PHP转Go系列 | GET 和 POST 请求的使用姿势

package main

import (
    "fmt"
    "net/http"
    "io/ioutil"
)

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

func handler(w http.ResponseWriter, r *http.Request) {
    switch r.Method {
    case "GET":
        getHandler(w, r)
    case "POST":
        postHandler(w, r)
    default:
        http.Error(w, "Method Not Allowed", http.StatusMethodNotAllowed)
    }
}

func getHandler(w http.ResponseWriter, r *http.Request) {
    // 获取查询参数
    query := r.URL.Query()
    name := query.Get("name")
    fmt.Fprintf(w, "Hello, %s!", name)
}

func postHandler(w http.ResponseWriter, r *http.Request) {
    // 解析请求体
    body, err := ioutil.ReadAll(r.Body)
    if err != nil {
        http.Error(w, "Internal Server Error", http.StatusInternalServerError)
        return
    }
    defer r.Body.Close()

    // 假设请求体是URL编码的表单数据
    formData := string(body)
    fmt.Fprintf(w, "Form Data: %s", formData)
}
