Golang里实现Http服务器并解析header参数和表单参数
package serverimport (
"net/http"
"strconv"
"fmt"
)
func HttpStart(port int){
http.HandleFunc("/hello", helloFunc)
err := http.ListenAndServe(":"+strconv.Itoa(port), nil)
if err != nil {
fmt.Println("监听失败：",err.Error())
}
}
func helloFunc(w http.ResponseWriter, r *http.Request){
fmt.Println("打印Header参数列表：")
if len(r.Header) > 0 {
for k,v := range r.Header {
fmt.Printf("%s=%s\n", k, v)
}
}
fmt.Println("打印Form参数列表：")
r.ParseForm()
if len(r.Form) > 0 {
for k,v := range r.Form {
fmt.Printf("%s=%s\n", k, v)
}
}
//验证用户名密码，如果成功则header里返回session，失败则返回StatusUnauthorized状态码
w.WriteHeader(http.StatusOK)
if (r.Form.Get("user") == "admin") && (r.Form.Get("pass") == "888") {
w.Write([]byte("hello,验证成功！"))
} else {
w.Write([]byte("hello,验证失败了！"))
}
}
