+# go-restful-swagger12
+
+[](https://travis-ci.org/emicklei/go-restful-swagger12)
+[](https://godoc.org/github.com/emicklei/go-restful-swagger12)
+
+How to use Swagger UI with go-restful
+=
+
+Get the Swagger UI sources (version 1.2 only)
+
+ git clone https://github.com/wordnik/swagger-ui.git
+
+The project contains a "dist" folder.
+Its contents has all the Swagger UI files you need.
+
+The `index.html` has an `url` set to `http://petstore.swagger.wordnik.com/api/api-docs`.
+You need to change that to match your WebService JSON endpoint e.g. `http://localhost:8080/apidocs.json`
+
+Now, you can install the Swagger WebService for serving the Swagger specification in JSON.
+
+ config := swagger.Config{
+ WebServices: restful.RegisteredWebServices(),
+ ApiPath: "/apidocs.json",
+ SwaggerPath: "/apidocs/",
+ SwaggerFilePath: "/Users/emicklei/Projects/swagger-ui/dist"}
+ swagger.InstallSwaggerService(config)
+
+
+Documenting Structs
+--
+
+Currently there are 2 ways to document your structs in the go-restful Swagger.
+
+###### By using struct tags
+- Use tag "description" to annotate a struct field with a description to show in the UI
+- Use tag "modelDescription" to annotate the struct itself with a description to show in the UI. The tag can be added in an field of the struct and in case that there are multiple definition, they will be appended with an empty line.
+
+###### By using the SwaggerDoc method
+Here is an example with an `Address` struct and the documentation for each of the fields. The `""` is a special entry for **documenting the struct itself**.
+
+ type Address struct {
+ Country string `json:"country,omitempty"`
+ PostCode int `json:"postcode,omitempty"`
+ }
+
+ func (Address) SwaggerDoc() map[string]string {
+ return map[string]string{
+ "": "Address doc",
+ "country": "Country doc",
+ "postcode": "PostCode doc",
+ }
+ }
+
+This example will generate a JSON like this
+
+ {
+ "Address": {
+ "id": "Address",
+ "description": "Address doc",
+ "properties": {
+ "country": {
+ "type": "string",
+ "description": "Country doc"
+ },
+ "postcode": {
+ "type": "integer",
+ "format": "int32",
+ "description": "PostCode doc"
+ }
+ }
+ }
+ }
+
+**Very Important Notes:**
+- `SwaggerDoc()` is using a **NON-Pointer** receiver (e.g. func (Address) and not func (*Address))
+- The returned map should use as key the name of the field as defined in the JSON parameter (e.g. `"postcode"` and not `"PostCode"`)
+
+Notes
+--
+- The Nickname of an Operation is automatically set by finding the name of the function. You can override it using RouteBuilder.Operation(..)
+- The WebServices field of swagger.Config can be used to control which service you want to expose and document ; you can have multiple configs and therefore multiple endpoints.

+go-restful
+==========
+package for building REST-style Web Services using Google Go
+
+[](https://travis-ci.org/emicklei/go-restful)
+[](https://goreportcard.com/report/github.com/emicklei/go-restful)
+[](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 → 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 → 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
+- Use [jsoniter](https://github.com/json-iterator/go) by build this package using a tag, e.g. `go build -tags=jsoniter .`
+
+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.
