go的net/http的http-form

go http-form 表格获取数据

package main

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

var form string = `<!DOCTYPE html>
<html>
<head>
	<title></title>
</head>
<body>
	<form action="#" method="post" name="bar">
		<input type="text" name="in" />
		<input type="text" name="in" />
		<input type="submit" value="Submit" />
	</form>
</body>
</html>`

func SimpleServer(w http.ResponseWriter, request *http.Request) {
	io.WriteString(w, "<h1>Hello, world.</h1>")
}

func FormServer(w http.ResponseWriter, request *http.Request) {
	w.Header().Set("Content-Type", "text/html")
	switch request.Method {
	case "GET":
		io.WriteString(w, form)
	case "POST":
		request.ParseForm()
		io.WriteString(w, "request.Form[in][0] :\n")
		io.WriteString(w, request.Form["in"][0])
		io.WriteString(w, "\t")

		io.WriteString(w, "request.Form[in][1] :\n")
		io.WriteString(w, request.Form["in"][1])
		io.WriteString(w, "\t\n")

		// request.FormValue("in")  只能取到第一个值,request.Form["in"]取到数组
		io.WriteString(w, request.FormValue("in"))
		io.WriteString(w, "\t")
		fmt.Printf("request.Form[in]= %v,%T \n",request.Form["in"],request.Form["in"])
		fmt.Printf("request.FormValue(\"in\")= %v,%T \n",request.FormValue("in"),request.FormValue("in"))

	}
}

func main() {
	http.HandleFunc("/test1", SimpleServer)
	http.HandleFunc("/test2", FormServer)
	if err := http.ListenAndServe(":8888", nil); err != nil {
	}
}

go http 增加pannic判断

package main

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

func main() {
	http.HandleFunc("/", LogPanic(test))
	http.HandleFunc("/form", LogPanic(form))
	err := http.ListenAndServe(":9000", nil)
	if err != nil {
		fmt.Println("服务开启失败", err)
		return
	}
}

func test(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, "hello")
	panic("test")
}

func form(w http.ResponseWriter, request *http.Request) {
	var fromTable string = `<html><head></head><body>
	<form method="post" action="">
	<input type="text" name="test" />
	<input type="text" name="test" />
	<input type="submit" name="提交" />
	</from>
	</body></html>`
	w.Header().Set("Content-Type", "text/html")
	switch request.Method {
	case "GET":
		io.WriteString(w, fromTable)
	case "POST":
		request.ParseForm()
		io.WriteString(w, request.Form["test"][1])
		io.WriteString(w, "\n")
		io.WriteString(w, request.FormValue("test"))
	}
}

func LogPanic(handler http.HandlerFunc) http.HandlerFunc {
	return func(w http.ResponseWriter, r *http.Request) {
		defer func() {
			if x := recover(); x != nil {
				log.Printf("%v panic:%v", r.RemoteAddr, x)
			}
		}()
		handler(w, r)
	}
}
