Go Gorilla mux 处理 API 个请求

Question

我想从以下 Gorilla Mux 路由器获取地图结构 input.package main

例如，

 router.Methods("GET").Path("/api/{action}").HandlerFunc(httpLog(myHandler))

func myHandler(rw http.ResponseWriter, r *http.Request) {
    vars := mux.Vars(r)
    log.Println(vars["action"])
}

服务于 0.0.0.0:3000/api/input，这会打印出字符串 input

如果我想接收这样的请求怎么办：

0.0.0.0:3000/api/v3?id=hello&password=great&product=ipad&confirm=true

根据这个请求，我想得到一张地图：

map["id"] = "hello"
map["password"] = "great"
map["product"] = "ipad"
map["confirm"] = "true"

Answer 1

你要我做吗？

func myHandler(r http.ResponseWriter, q *http.Request) {
    vars := mux.Vars(q)
    fmt.Println(vars["action"])

    fmt.Println(q.FormValue("id"))
    fmt.Println(q.FormValue("password"))
    fmt.Println(q.FormValue("product")) 
    fmt.Println(q.FormValue("confirm"))     
}

Answer 2

您可以在路由器上使用查询方法

package main

import (
    "fmt"
    "net/http"

    "github.com/gorilla/mux"
)

func main() {
    router := mux.NewRouter().Queries("id", "{id:[a-z]+}", "password", "{password:[a-z]+}", "product", "{product:[a-z]+}", "confirm", "{confirm:true|false}")
    request, _ := http.NewRequest("GET", "http://example.com?id=hello&password=great&product=ipad&confirm=true", nil)

    var match mux.RouteMatch
    router.Match(request, &match)
    fmt.Println(match.Vars)
}
