+[![Build Status](https://travis-ci.org/emicklei/go-restful.png)](https://travis-ci.org/emicklei/go-restful)
+[![Go Report Card](https://goreportcard.com/badge/github.com/emicklei/go-restful)](https://goreportcard.com/report/github.com/emicklei/go-restful)
+[![GoDoc](https://godoc.org/github.com/emicklei/go-restful?status.svg)](https://godoc.org/github.com/emicklei/go-restful)
+
+- [Code examples](https://github.com/emicklei/go-restful/tree/master/examples)
+
+REST asks developers to use HTTP methods explicitly and in a way that's consistent with the protocol definition. This basic REST design principle establishes a one-to-one mapping between create, read, update, and delete (CRUD) operations and HTTP methods. According to this mapping:
+
+- GET = Retrieve a representation of a resource
+- POST = Create if you are sending content to the server to create a subordinate of the specified resource collection, using some server-side algorithm.
+- PUT = Create if you are sending the full content of the specified resource (URI).
+- PUT = Update if you are updating the full content of the specified resource.
+- DELETE = Delete if you are requesting the server to delete the resource
+- PATCH = Update partial content of a resource
+- OPTIONS = Get information about the communication options for the request URI
+    
+### Example
+
+```Go
+ws := new(restful.WebService)
+ws.
+	Path("/users").
+	Consumes(restful.MIME_XML, restful.MIME_JSON).
+	Produces(restful.MIME_JSON, restful.MIME_XML)
+
+ws.Route(ws.GET("/{user-id}").To(u.findUser).
+	Doc("get a user").
+	Param(ws.PathParameter("user-id", "identifier of the user").DataType("string")).
+	Writes(User{}))		
+...
+	
+func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
+	id := request.PathParameter("user-id")
+	...
+}
+```
+	
+[Full API of a UserResource](https://github.com/emicklei/go-restful/tree/master/examples/restful-user-resource.go) 
+		
+### Features
+
+- Routes for request &#8594; function mapping with path parameter (e.g. {id}) support
+- Configurable router:
+	- (default) Fast routing algorithm that allows static elements, regular expressions and dynamic parameters in the URL path (e.g. /meetings/{id} or /static/{subpath:*}
+	- Routing algorithm after [JSR311](http://jsr311.java.net/nonav/releases/1.1/spec/spec.html) that is implemented using (but does **not** accept) regular expressions
+- Request API for reading structs from JSON/XML and accesing parameters (path,query,header)
+- Response API for writing structs to JSON/XML and setting headers
+- Customizable encoding using EntityReaderWriter registration
+- Filters for intercepting the request &#8594; response flow on Service or Route level
+- Request-scoped variables using attributes
+- Containers for WebServices on different HTTP endpoints
+- Content encoding (gzip,deflate) of request and response payloads
+- Automatic responses on OPTIONS (using a filter)
+- Automatic CORS request handling (using a filter)
+- API declaration for Swagger UI ([go-restful-openapi](https://github.com/emicklei/go-restful-openapi), see [go-restful-swagger12](https://github.com/emicklei/go-restful-swagger12))
+- Panic recovery to produce HTTP 500, customizable using RecoverHandler(...)
+- Route errors produce HTTP 404/405/406/415 errors, customizable using ServiceErrorHandler(...)
+- Configurable (trace) logging
+- Customizable gzip/deflate readers and writers using CompressorProvider registration
+
+## How to customize
+There are several hooks to customize the behavior of the go-restful package.
+
+- Router algorithm
+- Panic recovery
+- JSON decoder
+- Trace logging
+- Compression
+- Encoders for other serializers
+
+TODO: write examples of these.

+Package restful , a lean package for creating REST-style WebServices without magic.
+
+WebServices and Routes
+
+A WebService has a collection of Route objects that dispatch incoming Http Requests to a function calls.
+Typically, a WebService has a root path (e.g. /users) and defines common MIME types for its routes.
+WebServices must be added to a container (see below) in order to handler Http requests from a server.
+
+A Route is defined by a HTTP method, an URL path and (optionally) the MIME types it consumes (Content-Type) and produces (Accept).
+This package has the logic to find the best matching Route and if found, call its Function.
+
+	ws := new(restful.WebService)
+	ws.
+		Path("/users").
+		Consumes(restful.MIME_JSON, restful.MIME_XML).
+		Produces(restful.MIME_JSON, restful.MIME_XML)
+
+	ws.Route(ws.GET("/{user-id}").To(u.findUser))  // u is a UserResource
+
+	...
+
+	// GET http://localhost:8080/users/1
+	func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
+		id := request.PathParameter("user-id")
+		...
+	}
+
+The (*Request, *Response) arguments provide functions for reading information from the request and writing information back to the response.
+
+See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-user-resource.go with a full implementation.
+
+Regular expression matching Routes
+
+A Route parameter can be specified using the format "uri/{var[:regexp]}" or the special version "uri/{var:*}" for matching the tail of the path.
+For example, /persons/{name:[A-Z][A-Z]} can be used to restrict values for the parameter "name" to only contain capital alphabetic characters.
+Regular expressions must use the standard Go syntax as described in the regexp package. (https://code.google.com/p/re2/wiki/Syntax)
+This feature requires the use of a CurlyRouter.
+
+Containers
+
+A Container holds a collection of WebServices, Filters and a http.ServeMux for multiplexing http requests.
+Using the statements "restful.Add(...) and restful.Filter(...)" will register WebServices and Filters to the Default Container.
+The Default container of go-restful uses the http.DefaultServeMux.
+You can create your own Container and create a new http.Server for that particular container.
+
+	container := restful.NewContainer()
+	server := &http.Server{Addr: ":8081", Handler: container}
+
+Filters
+
+A filter dynamically intercepts requests and responses to transform or use the information contained in the requests or responses.
+You can use filters to perform generic logging, measurement, authentication, redirect, set response headers etc.
+In the restful package there are three hooks into the request,response flow where filters can be added.
+Each filter must define a FilterFunction:
+
+	func (req *restful.Request, resp *restful.Response, chain *restful.FilterChain)
+
+Use the following statement to pass the request,response pair to the next filter or RouteFunction
+
+	chain.ProcessFilter(req, resp)
+
+Container Filters
+
+These are processed before any registered WebService.
+
+	// install a (global) filter for the default container (processed before any webservice)
+	restful.Filter(globalLogging)
+
+WebService Filters
+
+These are processed before any Route of a WebService.
+
+	// install a webservice filter (processed before any route)
+	ws.Filter(webserviceLogging).Filter(measureTime)
+
+
+Route Filters
+
+These are processed before calling the function associated with the Route.
+
+	// install 2 chained route filters (processed before calling findUser)
+	ws.Route(ws.GET("/{user-id}").Filter(routeLogging).Filter(NewCountFilter().routeCounter).To(findUser))
+
+See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-filters.go with full implementations.
+
+Response Encoding
+
+Two encodings are supported: gzip and deflate. To enable this for all responses:
+
+	restful.DefaultContainer.EnableContentEncoding(true)
+
+If a Http request includes the Accept-Encoding header then the response content will be compressed using the specified encoding.
+Alternatively, you can create a Filter that performs the encoding and install it per WebService or Route.
+
+See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-encoding-filter.go
+
+OPTIONS support
+
+By installing a pre-defined container filter, your Webservice(s) can respond to the OPTIONS Http request.
+
+	Filter(OPTIONSFilter())
+
+CORS
+
+By installing the filter of a CrossOriginResourceSharing (CORS), your WebService(s) can handle CORS requests.
+
+	cors := CrossOriginResourceSharing{ExposeHeaders: []string{"X-My-Header"}, CookiesAllowed: false, Container: DefaultContainer}
+	Filter(cors.Filter)
+
+Error Handling
+
+Unexpected things happen. If a request cannot be processed because of a failure, your service needs to tell via the response what happened and why.
+For this reason HTTP status codes exist and it is important to use the correct code in every exceptional situation.
+
+	400: Bad Request
+
+If path or query parameters are not valid (content or type) then use http.StatusBadRequest.
+
+	404: Not Found
+
+Despite a valid URI, the resource requested may not be available
+
+	500: Internal Server Error
+
+If the application logic could not process the request (or write the response) then use http.StatusInternalServerError.
+
+	405: Method Not Allowed
+
+The request has a valid URL but the method (GET,PUT,POST,...) is not allowed.
+
+	406: Not Acceptable
+
+The request does not have or has an unknown Accept Header set for this operation.
+
+	415: Unsupported Media Type
+
+The request does not have or has an unknown Content-Type Header set for this operation.
+
+ServiceError
+
+In addition to setting the correct (error) Http status code, you can choose to write a ServiceError message on the response.
+
+Performance options
+
+This package has several options that affect the performance of your service. It is important to understand them and how you can change it.
+
+	restful.DefaultContainer.DoNotRecover(false)
+
+DoNotRecover controls whether panics will be caught to return HTTP 500.
+If set to false, the container will recover from panics.
+Default value is true
+
+	restful.SetCompressorProvider(NewBoundedCachedCompressors(20, 20))
+
+If content encoding is enabled then the default strategy for getting new gzip/zlib writers and readers is to use a sync.Pool.
+Because writers are expensive structures, performance is even more improved when using a preloaded cache. You can also inject your own implementation.
+
+Trouble shooting
+
+This package has the means to produce detail logging of the complete Http request matching process and filter invocation.
+Enabling this feature requires you to set an implementation of restful.StdLogger (e.g. log.Logger) instance such as:
+
+	restful.TraceLogger(log.New(os.Stdout, "[restful] ", log.LstdFlags|log.Lshortfile))
+
+Logging
+
+The restful.SetLogger() method allows you to override the logger used by the package. By default restful
+uses the standard library `log` package and logs to stdout. Different logging packages are supported as
+long as they conform to `StdLogger` interface defined in the `log` sub-package, writing an adapter for your
+preferred package is simple.

+====
+
+Leveled execution logs for Go.
+
+This is an efficient pure Go implementation of leveled logs in the
+manner of the open source C++ package
+	https://github.com/google/glog
+
+By binding methods to booleans it is possible to use the log package
+without paying the expense of evaluating the arguments to the log.
+Through the -vmodule flag, the package also provides fine-grained
+control over logging at the file level.
+
+The comment from glog.go introduces the ideas:
+
+	Package glog implements logging analogous to the Google-internal
+	C++ INFO/ERROR/V setup.  It provides functions Info, Warning,
+	Error, Fatal, plus formatting variants such as Infof. It
+	also provides V-style logging controlled by the -v and
+	-vmodule=file=2 flags.
+	
+	Basic examples:
+	
+		glog.Info("Prepare to repel boarders")
+	
+		glog.Fatalf("Initialization failed: %s", err)
+	
+	See the documentation for the V function for an explanation
+	of these examples:
+	
+		if glog.V(2) {
+			glog.Info("Starting transaction...")
+		}
+	
+		glog.V(2).Infoln("Processed", nItems, "elements")
+
+
+The repository contains an open source version of the log package
+used inside Google. The master copy of the source lives inside
+Google, not here. The code in this repo is for export only and is not itself
+under development. Feature requests will be ignored.
+
+Send bug reports to golang-nuts@googlegroups.com.

+
+## Description
+
+pflag is a drop-in replacement for Go's flag package, implementing
+POSIX/GNU-style --flags.
+
+pflag is compatible with the [GNU extensions to the POSIX recommendations
+for command-line options][1]. For a more precise description, see the
+"Command-line flag syntax" section below.
+
+[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+pflag is available under the same style of BSD license as the Go language,
+which can be found in the LICENSE file.
+
+## Installation
+
+pflag is available using the standard `go get` command.
+
+Install by running:
+
+    go get github.com/spf13/pflag
+
+Run tests by running:
+
+    go test github.com/spf13/pflag
+
+## Usage
+
+pflag is a drop-in replacement of Go's native flag package. If you import
+pflag under the name "flag" then all code should continue to function
+with no changes.
+
+``` go
+import flag "github.com/spf13/pflag"
+```
+
+There is one exception to this: if you directly instantiate the Flag struct
+there is one more field "Shorthand" that you will need to set.
+Most code never instantiates this struct directly, and instead uses
+functions such as String(), BoolVar(), and Var(), and is therefore
+unaffected.
+
+Define flags using flag.String(), Bool(), Int(), etc.
+
+This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+
+``` go
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+```
+
+If you like, you can bind the flag to a variable using the Var() functions.
+
+``` go
+var flagvar int
+func init() {
+    flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+}
+```
+
+Or you can create custom flags that satisfy the Value interface (with
+pointer receivers) and couple them to flag parsing by
+
+``` go
+flag.Var(&flagVal, "name", "help message for flagname")
+```
+
+For such flags, the default value is just the initial value of the variable.
+
+After all flags are defined, call
+
+``` go
+flag.Parse()
+```
+
+to parse the command line into the defined flags.
+
+Flags may then be used directly. If you're using the flags themselves,
+they are all pointers; if you bind to variables, they're values.
+
+``` go
+fmt.Println("ip has value ", *ip)
+fmt.Println("flagvar has value ", flagvar)
+```
+
+There are helpers function to get values later if you have the FlagSet but
+it was difficult to keep up with all of the flag pointers in your code.
+If you have a pflag.FlagSet with a flag called 'flagname' of type int you
+can use GetInt() to get the int value. But notice that 'flagname' must exist
+and it must be an int. GetString("flagname") will fail.
+
+``` go
+i, err := flagset.GetInt("flagname")
+```
+
+After parsing, the arguments after the flag are available as the
+slice flag.Args() or individually as flag.Arg(i).
+The arguments are indexed from 0 through flag.NArg()-1.
+
+The pflag package also defines some new functions that are not in flag,
+that give one-letter shorthands for flags. You can use these by appending
+'P' to the name of any function that defines a flag.
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+var flagvar bool
+func init() {
+	flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
+}
+flag.VarP(&flagVal, "varname", "v", "help message")
+```
+
+Shorthand letters can be used with single dashes on the command line.
+Boolean shorthand flags can be combined with other shorthand flags.
+
+The default set of command-line flags is controlled by
+top-level functions.  The FlagSet type allows one to define
+independent sets of flags, such as to implement subcommands
+in a command-line interface. The methods of FlagSet are
+analogous to the top-level functions for the command-line
+flag set.
+
+## Setting no option default values for flags
+
+After you create a flag it is possible to set the pflag.NoOptDefVal for
+the given flag. Doing this changes the meaning of the flag slightly. If
+a flag has a NoOptDefVal and the flag is set on the command line without
+an option the flag will be set to the NoOptDefVal. For example given:
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+flag.Lookup("flagname").NoOptDefVal = "4321"
+```
+
+Would result in something like
+
+| Parsed Arguments | Resulting Value |
+| -------------    | -------------   |
+| --flagname=1357  | ip=1357         |
+| --flagname       | ip=4321         |
+| [nothing]        | ip=1234         |
+
+## Command line flag syntax
+
+```
+--flag    // boolean flags, or flags with no option default values
+--flag x  // only on flags without a default value
+--flag=x
+```
+
+Unlike the flag package, a single dash before an option means something
+different than a double dash. Single dashes signify a series of shorthand
+letters for flags. All but the last shorthand letter must be boolean flags
+or a flag with a default value
+
+```
+// boolean or flags where the 'no option default value' is set
+-f
+-f=true
+-abc
+but
+-b true is INVALID
+
+// non-boolean and flags without a 'no option default value'
+-n 1234
+-n=1234
+-n1234
+
+// mixed
+-abcs "hello"
+-absd="hello"
+-abcs1234
+```
+
+Flag parsing stops after the terminator "--". Unlike the flag package,
+flags can be interspersed with arguments anywhere on the command line
+before this terminator.
+
+Integer flags accept 1234, 0664, 0x1234 and may be negative.
+Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+TRUE, FALSE, True, False.
+Duration flags accept any input valid for time.ParseDuration.
+
+## Mutating or "Normalizing" Flag names
+
+It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow.
+
+**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag
+
+``` go
+func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+	from := []string{"-", "_"}
+	to := "."
+	for _, sep := range from {
+		name = strings.Replace(name, sep, to, -1)
+	}
+	return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc)
+```
+
+**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name
+
+``` go
+func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+	switch name {
+	case "old-flag-name":
+		name = "new-flag-name"
+		break
+	}
+	return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(aliasNormalizeFunc)
+```
+
+## Deprecating a flag or its shorthand
+It is possible to deprecate a flag, or just its shorthand. Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used.
+
+**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead.
+```go
+// deprecate a flag by specifying its name and a usage message
+flags.MarkDeprecated("badflag", "please use --good-flag instead")
+```
+This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used.
+
+**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n".
+```go
+// deprecate a flag shorthand by specifying its flag name and a usage message
+flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only")
+```
+This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used.
+
+Note that usage message is essential here, and it should not be empty.
+
+## Hidden flags
+It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
+
+**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
+```go
+// hide a flag by specifying its name
+flags.MarkHidden("secretFlag")
+```
+
+## Disable sorting of flags
+`pflag` allows you to disable sorting of flags for help and usage message.
+
+**Example**:
+```go
+flags.BoolP("verbose", "v", false, "verbose output")
+flags.String("coolflag", "yeaah", "it's really cool flag")
+flags.Int("usefulflag", 777, "sometimes it's very useful")
+flags.SortFlags = false
+flags.PrintDefaults()
+```
+**Output**:
+```
+  -v, --verbose           verbose output
+      --coolflag string   it's really cool flag (default "yeaah")
+      --usefulflag int    sometimes it's very useful (default 777)
+```
+
+
+## Supporting Go flags when using pflag
+In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
+to support flags defined by third-party dependencies (e.g. `golang/glog`).
+
+**Example**: You want to add the Go flags to the `CommandLine` flagset
+```go
+import (
+	goflag "flag"
+	flag "github.com/spf13/pflag"
+)
+
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+
+func main() {
+	flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
+	flag.Parse()
+}
+```
+
+## More info
+
+You can see the full reference documentation of the pflag package
+[at godoc.org][3], or through go's standard documentation system by
+running `godoc -http=:6060` and browsing to
+[http://localhost:6060/pkg/github.com/spf13/pflag][2] after
+installation.
