HTTP Proxy Demo 代码
1、Python
#! -- encoding:utf-8 --
import requests
# 要访问的目标页面
targetUrl = "http://ip.hahado.cn/ip"
# 代理服务器
proxyHost = "ip.hahado.cn"
proxyPort = "39010"
# 代理隧道验证信息
proxyUser = "username"
proxyPass = "password"
proxyMeta = "http://%(user)s:%(pass)s@%(host)s:%(port)s" % {
"host" : proxyHost,
"port" : proxyPort,
"user" : proxyUser,
"pass" : proxyPass,
}
proxies = {
"http" : proxyMeta,
"https" : proxyMeta,
}
resp = requests.get(targetUrl, proxies=proxies)
print resp.status_code
print resp.text
2、C Sharp
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://ip.hahado.cn/ip");
WebProxy myProxy = new WebProxy();
Uri newUri = new Uri("http://ip.hahado.cn:39010");
myProxy.Address = newUri;
myProxy.Credentials = new NetworkCredential("username", "password");
request.Proxy = myProxy;
3、PHP
// 要访问的目标页面
$targetUrl = "http://ip.hahado.cn/ip";
//$targetUrl = "http://ip.hahado.cn/switch-ip";
//$targetUrl = "http://ip.hahado.cn/current-ip";
// 代理服务器
define("PROXY_SERVER", "ip.hahado.cn:39010");
// 隧道身份信息
define("PROXY_USER", "username");
define("PROXY_PASS", "password");
$proxyAuth = base64_encode(PROXY_USER . ":" . PROXY_PASS);
$headers = implode("\r\n", [
"Proxy-Authorization: Basic {$proxyAuth}",
"Proxy-Switch-Ip: yes",
]);
$options = [
"http" => [
"proxy" => $proxyServer,
"header" => $headers,
"method" => "GET",
],
];
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);
4、JAVA
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import java.net.Authenticator;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.PasswordAuthentication;
import java.net.Proxy;
import java.net.URL;
class ProxyAuthenticator extends Authenticator {
private String user, password;
public ProxyAuthenticator(String user, String password) {
this.user = user;
this.password = password;
}
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, password.toCharArray());
}
}
/**
* 注意：下面代码仅仅实现HTTP请求链接，每一次请求都是无状态保留的，仅仅是这次请求是更换IP的，如果下次请求的IP地址会改变
* 如果是多线程访问的话，只要将下面的代码嵌入到你自己的业务逻辑里面，那么每次都会用新的IP进行访问，如果担心IP有重复，
* 自己可以维护IP的使用情况，并做校验。
*/
public class ProxyDemo {
public static void main(String args[]) throws Exception {
// 要访问的目标页面
String targetUrl = "http://ip.hahado.cn/ip";
//String targetUrl = "http://ip.hahado.cn/switch-ip";
//String targetUrl = "http://ip.hahado.cn/current-ip";
// 代理服务器

try {

// 创建代理服务器地址对象
InetSocketAddress addr = new InetSocketAddress(proxyServer, proxyPort);
// 创建HTTP类型代理对象

// 解析返回数据
byte[] response = readStream(connection.getInputStream());
System.out.println(new String(response));
} catch (Exception e) {
System.out.println(e.getLocalizedMessage());
}
}
/**
* 将输入流转换成字符串
*
* @param inStream
* @return
* @throws Exception
*/
public static byte[] readStream(InputStream inStream) throws Exception {
ByteArrayOutputStream outSteam = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len = -1;
while ((len = inStream.read(buffer)) != -1) {
outSteam.write(buffer, 0, len);
}
outSteam.close();
inStream.close();
return outSteam.toByteArray();
}
}
5、golang
package main
import (
"net/url"
"net/http"
"bytes"
"fmt"
"io/ioutil"
)
const ProxyServer = "ip.hahado.cn:39010"
type ProxyAuth struct {
License string
SecretKey string
}
func (p ProxyAuth) ProxyClient() http.Client {
proxyURL, _ := url.Parse("http://" + p.License + ":" + p.SecretKey + "@" + ProxyServer)
return http.Client{Transport: &http.Transport{Proxy:http.ProxyURL(proxyURL)}}
}
func main() {
targetURI := "http://ip.hahaod.cn/ip"
//targetURI := "http://ip.hahaod.cn/switch-ip"
//targetURI := "http://ip.hahaod.cn/current-ip"
// 初始化 proxy http client
client := ProxyAuth{License: "username", SecretKey: "password"}.ProxyClient()
request, _ := http.NewRequest("GET", targetURI, bytes.NewBuffer([] byte(``)))
// 切换IP (只支持 HTTP)
request.Header.Set("Proxy-Switch-Ip", "yes")
response, err := client.Do(request)
if err != nil {
panic("failed to connect: " + err.Error())
} else {
bodyByte, err := ioutil.ReadAll(response.Body)
if err != nil {
fmt.Println("读取 Body 时出错", err)
return
}
response.Body.Close()
body := string(bodyByte)
fmt.Println("Response Status:", response.Status)
fmt.Println("Response Header:", response.Header)
fmt.Println("Response Body:\n", body)
}
}
