Python 语言和 go 语言 http 请求使用代理的差异( Python 可以正常跑， go 不行)

请大佬们帮忙看下，go 怎么才能通过代理成功发起请求

我也试了 php 也不行

python 代码

import requests def send_request_via_proxy(*args, **kwargs): baidu_proxy = 'http://cloudnproxy.baidu.com:443' kwargs['proxies'] = {'http': baidu_proxy, 'https': baidu_proxy} if 'headers' not in kwargs: kwargs['headers'] = {} if 'User-Agent' not in kwargs['headers']: kwargs['headers'][ 'User-Agent'] = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36 baiduboxapp/13.10.0.10' resp = requests.request(*args, **kwargs) print(resp.request.headers) print(resp.request) return resp if __name__ == '__main__': api = 'https://pubstatic.b0.upaiyun.com/?_upnode' ip_info = send_request_via_proxy('GET', api).json() print(ip_info['remote_addr']) print(ip_info['remote_addr_location']) 

go 代码

package main import ( "fmt" "io" "log" "net/http" "net/url" "time" ) func main() { URL, _ := url.Parse("http://cloudnproxy.baidu.com:443") client := &http.Client{ Transport: &http.Transport{ TLSHandshakeTimeout: 30 * time.Second, Proxy: http.ProxyURL(URL), }, } req, err := http.NewRequest("GET", "https://pubstatic.b0.upaiyun.com/?_upnode", nil) if err != nil { log.Fatal(err) } req.Header.Set("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36(KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36 baiduboxapp/13.10.0.10") resp, err := client.Do(req) if err != nil { log.Fatal(err) } defer resp.Body.Close() bodyText, err := io.ReadAll(resp.Body) if err != nil { log.Fatal(err) } fmt.Printf("%s\n", bodyText) }
