如何使用golang中的http.Post函数发送POST请求并获取响应

import "net/http"

values := url.Values{}
values.Set("key1", "value1")
values.Set("key2", "value2")

url := "http://example.com/api"  // 要发送的POST请求的URL
body := strings.NewReader(values.Encode())  // 将请求参数编码成字节流
response, err := http.Post(url, "application/x-www-fORM-urlencoded", body)  // 发送POST请求
if err != nil {
    fmt.Println("发送POST请求失败：", err)
    return
}
defer response.Body.Close()

result, err := ioutil.ReadAll(response.Body)  // 读取响应结果
if err != nil {
    fmt.Println("读取响应结果失败：", err)
    return
}
fmt.Println("响应结果：", string(result))  // 输出响应结果

package main

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

func main() {
    values := url.Values{}
    values.Set("key1", "value1")
    values.Set("key2", "value2")

    url := "http://example.com/api"
    body := strings.NewReader(values.Encode())
    response, err := http.Post(url, "application/x-www-form-urlencoded", body)
    if err != nil {
        fmt.Println("发送POST请求失败：", err)
        return
    }
    defer response.Body.Close()

    result, err := ioutil.ReadAll(response.Body)
    if err != nil {
        fmt.Println("读取响应结果失败：", err)
        return
    }
    fmt.Println("响应结果：", string(result))
}
