代碼示例

Swiftproxy 讓開發者輕鬆將高品質住宅代理及靜態住宅代理整合到程式碼中。無論您使用的是 HTTP、HTTPS 或 SOCKS5 協議，我們的代理皆完全相容於主流程式語言與工具。

本節提供多種環境下的程式碼整合範例，幫助您在實際應用場景中實現代理支持，例如網頁爬蟲、數據彙整、SEO 監控等。

Python

// import requests
if __name__ == '__main__':
proxyip = "http://username_custom_zone_US:[email protected]:7878"
url = "http://ipinfo.io"
proxies = {
'http': proxyip,
}
data = requests.get(url=url, proxies=proxies)
print(data.text)

Node.js

// import fetch from 'node-fetch';
import createHttpsProxyAgent from 'https-proxy-agent'

const username = 'username_custom_zone_us';
const password = 'password';
const proxy = 'us.swiftproxy.net:7878'

const agent = createHttpsProxyAgent(
  `http://${username}:${password}@${proxy}`
);

const response = await fetch('http://ipinfo.io', {
  method: 'get',
  agent: agent,
});

console.log(await response.text());

PHP

// $ch = curl_init();
curl_setopt($ch, CURLOPT_PROXY, "us.swiftproxy.net" );
curl_setopt($ch, CURLOPT_PROXYUSERPWD, "username_custom_zone_us:password");
curl_setopt($ch, CURLOPT_PROXYTYPE,CURLPROXY_HTTP);
curl_setopt($ch, CURLOPT_URL, 'http://ipinfo.io');
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$result = curl_exec($ch);
curl_close($ch);
echo $result;

GO

// package main
import (
	"fmt"
	"io/ioutil"
	"net/http"
	"net/url"
	"os"
)
func main() {
	proxyURL, _ := url.Parse("http://username_custom_zone_US:[email protected]:7878")
	proxy := http.ProxyURL(proxyURL)
	transport := &http.Transport{
		Proxy: proxy,
	}
	client := &http.Client{
		Transport: transport,
	}
	targetURL := "http://ipinfo.io"

	resp, err := client.Get(targetURL)
	if err != nil {
		fmt.Fprintln(os.Stderr, "Error fetching from", targetURL, ":", err)
		os.Exit(1)
	}
	defer resp.Body.Close()

	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		fmt.Fprintln(os.Stderr, "Error reading response body:", err)
		os.Exit(1)
	}

	fmt.Println(string(body))
}
