Proxy Rotator - 可选

了解 Proxy Rotator、其作为轮换端点的功能以及其会话控制功能。

如果您想使用 Proxy Rotator，此服务是可选的——请联系您的客户经理以获取一个域名。

我们不直接连接到单个 IP，而是为你提供一个单一端点，指向你分配的代理列表。每次请求时，该端点都会获取不同的 IP。请参见下面的示例，了解如何将该端点用作代理。

该 vm.oxylabs.io 域名仅为示例。请联系您的客户经理，以获取转发给您的域名。

Proxy Rotator 只能与端口一起使用 60000.

代码示例

curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location

<?php
$query = curl_init('https://ip.oxylabs.io/location');
curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($query, CURLOPT_PROXY, 'http://vm.oxylabs.io:60000');
curl_setopt($query, CURLOPT_PROXYUSERPWD, "username:password");
$output = curl_exec($query);
curl_close($query);
if ($output) {
    echo $output;
}

import requests

response = requests.get(
    'https://ip.oxylabs.io/location',
    代理={'http': 'http://user1:pass1@vm.oxylabs.io:60000',
            'https': 'http://user1:pass1@vm.oxylabs.io:60000'}
)
print(response.text)

using System;
using System.Net;

class Example
{
    static void Main()
    {
        var proxy = new WebProxy
        {
            Address = new Uri($"http://vm.oxylabs.io:60000"),
            BypassProxyOnLocal = false,
            UseDefaultCredentials = false,
            Credentials = new NetworkCredential("username", "password")
        };

        var handler = new HttpClientHandler
        {
            Proxy = proxy,
        };

        HttpClient client = new HttpClient(handler);
        var task = Task.Run(async () =>
        {
            var response = await client.GetAsync("https://ip.oxylabs.io/location");
            var content = response.Content;
            var result = await content.ReadAsStringAsync();
            return result;
        });

        task.Wait();
        Console.WriteLine(task.Result);
    }
}

代理轮换只会从您在初始设置期间选择的 ASN 中的代理中选择 IP。自动轮换不会切换到其他 ISP，也不会更改您未选择的 ASN。

使用 Proxy Rotator 进行会话控制

可以使用 Proxy Rotator 保持相同的 IP 地址。首先，您需要知道您的 Proxy Rotator 有多少个代理。然后添加 --proxy-header "Proxy-Server: sXXX" 标头到您的请求中，其中 sXXX 是代理编号，例如， s5 或 s2541.

代码示例

user1@machine:~$ curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location --proxy-header "Proxy-Server: s10"
1.2.30.40
user1@machine:~$ curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location --proxy-header "Proxy-Server: s10"
1.2.30.40
user1@machine:~$ curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location --proxy-header "Proxy-Server: s10"
1.2.30.40

<?php
$query = curl_init('https://ip.oxylabs.io/location');
curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($query, CURLOPT_PROXY, 'http://vm.oxylabs.io:60000');
curl_setopt($query, CURLOPT_PROXYUSERPWD, "username:password");
curl_setopt($query, CURLOPT_PROXYHEADER, [
    "Proxy-Server: s10",
]);

$output = curl_exec($query);
curl_close($query);
if ($output) {
    echo $output;
}

import requests


class ProxyAdapter(requests.adapters.HTTPAdapter):
    def proxy_headers(self, proxy):
        headers = super(ProxyAdapter, self).proxy_headers(proxy)
        headers['Proxy-Server'] = 's10'
        return headers


s = requests.Session()
s.proxies = {'http': 'http://username:password@vm.oxylabs.io:60000',
             "https": "http://username:password@vm.oxylabs.io:60000'}"
s.mount('http://', ProxyAdapter())
s.mount('https://', ProxyAdapter())
response = s.get('https://ip.oxylabs.io/location')
print(response.text)

using System;
using System.Net;

class Example
{
    static void Main()
    {
        var client = new WebClient();
        client.Proxy = new WebProxy("http://vm.oxylabs.io:60000");
        client.Proxy.Credentials = new NetworkCredential("user1", "pass1");

        client.Headers.Add("Proxy-Server", "s10");

        Console.WriteLine(client.DownloadString("https://ip.oxylabs.io/location"));
    }
}

这有帮助吗？
