Golang HTTPS / TLS POST客户端/服务器

I have written a simple client/server in Go that will do an HTTP GET over TLS, but I'm trying to also make it capable of doing an HTTP POST over TLS.

In the example below index.html just contains the text hello, and the HTTP GET is working fine. I want the client to get the HTTP GET and write back, hello world to the server.


package main

import (

func main() {
    link := ""

    tr := &http.Transport{
        TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
    client := &http.Client{Transport: tr}
    response, err := client.Get(link)
    if err != nil {
    defer response.Body.Close()

    content, _ := ioutil.ReadAll(response.Body)
    s := strings.TrimSpace(string(content))


    // out := s + " world"      
    // Not working POST...
    // resp, err := client.Post(link, "text/plain", &out)



package main

import (

func main() {
    http.HandleFunc("/static/", func (w http.ResponseWriter, r *http.Request) {
        fmt.Println("Got connection!")
        http.ServeFile(w, r, r.URL.Path[1:])
    log.Fatal(http.ListenAndServeTLS(":443", "server.crt", "server.key", nil))

I also currently have nothing to handle the POST on the server side, but I just want it to print it out to the screen so when I run the client I will see the server print hello world.

How should I fix my client code to do a proper POST? And what should the corresponding server code look like to accept the POST? Any help would be appreciated, I'm having trouble finding HTTPS/TLS POST examples.

您没有共享错误消息,但是我认为 client.Post </ code>调用不允许 字符串作为第三个参数,因为它需要 io.Reader </ code>。 改试试这个:</ p>

  out:= s +“ world” 
resp,err:= client.Post(链接,“ text / plain”,bytes.NewBufferString(out) )
</ code> </ pre>

在服务器端,您已经设置了正确的代码来处理POST请求。 只需检查以下方法:</ p>

  http.HandleFunc(“ / static /”,func(w http.ResponseWriter,r * http.Request){
如果r.Method = =“ POST” {
</ code> </ pre>

I 注意到另一个问题。 使用 index.html </ code>在这里可能行不通。 http.ServeFile </ code>将重定向该路径。 请参见 https://golang.org/pkg/net/http/#ServeFile : </ p>

以“ /index.html”结尾的任何请求重定向到同一路径,而没有最终的\ n“ index.html”。 为避免此类重定向,请修改路径或使用
ServeContent。</ p>
</ blockquote>

我建议您仅使用其他文件名来避免该问题。</ p>

You didn't share the error message, but I assume the client.Post call wasn't allowing a string as its third parameter, because it requires an io.Reader. Try this instead:

out := s + " world"     
resp, err := client.Post(link, "text/plain", bytes.NewBufferString(out))

On the server side, you already have the right code set up to handle the POST request. Just check the method:

http.HandleFunc("/static/", func (w http.ResponseWriter, r *http.Request) {
    if r.Method == "POST" {
        // handle POST requests
    } else {
        // handle all other requests

I noticed one other issue. Using index.html probably won't work here. http.ServeFile will redirect that path. See https://golang.org/pkg/net/http/#ServeFile:

As a special case, ServeFile redirects any request where r.URL.Path ends in "/index.html" to the same path, without the final "index.html". To avoid such redirects either modify the path or use ServeContent.

I'd suggest just using a different file name to avoid that issue.
