将Web API暴露给使用Golang接受json和/或参数的第三方

An http package that wraps "net/http" will be helpful. Examples:

Here is a simple service to get you started:

package main

import (
    "github.com/emicklei/go-restful"
    "log"
    "net/http"
)

type User struct {
    Name string
}

func postOne(req *restful.Request, resp *restful.Response) {
    newUser := new(User)
    err := req.ReadEntity(newUser)
    if err != nil {
        resp.WriteErrorString(http.StatusBadRequest, err.Error())
        return
    }

    log.Printf("new user: '%v'", newUser)
}

func main() {
    ws := new(restful.WebService)
    ws.Path("/users")
    ws.Consumes(restful.MIME_JSON)
    ws.Produces(restful.MIME_JSON)

    ws.Route(ws.POST("").To(postOne).
        Param(ws.BodyParameter("User", "A User").DataType("main.User")))

   restful.Add(ws)

  http.ListenAndServe(":8080", nil)
}

Here is a curl to test the service by posting a single user:

curl -v -H "Content-Type: application/json" -XPOST "localhost:8080/users" -d '{"name": "Joe"}'
