Golang如何使用net/http发送GET请求_Golang HTTP GET请求实践

package main
<p>import (
"fmt"
"io/ioutil"
"log"
"net/http"
)</p><p>func main() {
resp, err := http.Get("<a href="https://www.php.cn/link/4d2fe2e8601f7a8018594d98f28706f2">https://www.php.cn/link/4d2fe2e8601f7a8018594d98f28706f2</a>")
if err != nil {
log.Fatal("请求失败:", err)
}
defer resp.Body.Close()</p><pre class="brush:php;toolbar:false;"><pre class="brush:php;toolbar:false;">body, err := ioutil.ReadAll(resp.Body)
if err != nil {
    log.Fatal("读取响应失败:", err)
}

fmt.Println(string(body))

client := &http.Client{
    Timeout: 10 * time.Second,
}
resp, err := client.Get("https://www.php.cn/link/4d2fe2e8601f7a8018594d98f28706f2")

<code>req, err := http.NewRequest("GET", "https://www.php.cn/link/4d2fe2e8601f7a8018594d98f28706f2", nil)
if err != nil {
    log.Fatal(err)
}
<p>// 可在此添加Header等配置
req.Header.Set("User-Agent", "my-client")</p><p>client := &http.Client{Timeout: 5 * time.Second}
resp, err := client.Do(req)
if err != nil {
log.Fatal(err)
}
defer resp.Body.Close()

type Response struct {
    Origin string `json:"origin"`
    URL    string `json:"url"`
}
<p>var data Response
err := json.NewDecoder(resp.Body).Decode(&data)
if err != nil {
log.Fatal("解析JSON失败:", err)
}
fmt.Printf("访问地址: %s, IP: %s\n", data.URL, data.Origin)

if resp.StatusCode != http.StatusOK {
    log.Fatalf("HTTP错误: %d", resp.StatusCode)
}
