我可以在GoLang post请求中发布json格式的数据吗[duplicate]

Question

所以我有一个php页面，我试图让我的GoLang客户端通过POST请求进行通信。php脚本通过key:value进行输入，key:value是message:hello world，希望添加多个键。它适用于我的python脚本，但不适用于golang，所以这里是我到目前为止在golang中的内容。

package main

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

func main() {
    resp, err := http.Post("http://127.0.0.1/project/devapi.php",
        url.Values{"message": {"Client has been connected"}})

    if err != nil {
        // handle error
    }

    defer resp.Body.Close()
    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        // handle error
    }

    fmt.Println(string(body))

}

尝试运行上述代码时收到的错误消息：

# command-line-arguments
Programs\Client\client.go:11:24: not enough arguments in call to http.Post
        have (string, url.Values)
        want (string, string, io.Reader)

php脚本是：

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    echo $_POST['message'];
}
?>

我能得到的最佳回复如下：

正是我要找的

package main

import (
    "bytes"
    "encoding/json"
    "fmt"
    "log"
    "net/http"
)

func main() {

    values := map[string]string{"name": "John Doe", "occupation": "gardener"}
    json_data, err := json.Marshal(values)

    if err != nil {
        log.Fatal(err)
    }

    resp, err := http.Post("https://httpbin.org/post", "application/json",
        bytes.NewBuffer(json_data))

    if err != nil {
        log.Fatal(err)
    }

    var res map[string]interface{}

    json.NewDecoder(resp.Body).Decode(&res)

    fmt.Println(res["json"])
}
