Golanghttp客户端请求代码示例

resp, err := http.Get("https://httpbin.org/get")
if err != nil {
    log.Fatal(err)
}
defer resp.Body.Close()
<p>body, err := io.ReadAll(resp.Body)
if err != nil {
log.Fatal(err)
}</p><p>fmt.Println(string(body))</p>

data := `{"name": "Alice", "age": 30}`
req, err := http.NewRequest("POST", "https://httpbin.org/post", strings.NewReader(data))
if err != nil {
    log.Fatal(err)
}
<p>req.Header.Set("Content-Type", "application/json")
req.Header.Set("Authorization", "Bearer your-token")</p><p>client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
log.Fatal(err)
}
defer resp.Body.Close()</p><p>body, _ := io.ReadAll(resp.Body)
fmt.Println(string(body))</p>

client := &http.Client{
    Timeout: 10 * time.Second,
}
<p>// 可进一步定制 Transport 来控制连接行为
transport := &http.Transport{
MaxIdleConns:       10,
IdleConnTimeout:    30 * time.Second,
DisableCompression: true,
}
client.Transport = transport</p>

resp, err := client.Do(req)
if err != nil {
    log.Fatal(err)
}
defer resp.Body.Close()
<p>if resp.StatusCode != http.StatusOK {
fmt.Printf("请求失败，状态码: %d\n", resp.StatusCode)
return
}</p><p>body, _ := io.ReadAll(resp.Body)
fmt.Println("响应内容:", string(body))</p>
