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")
|
|
...
|
|
}
|
|
```

### 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 (see [go-restful-swagger12](https://github.com/emicklei/go-restful-swagger12),[go-restful-openapi](https://github.com/emicklei/go-restful-openapi))
|
|
- 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
