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.
