代理轮换
了解如何使用 ISP 代理的代理轮换功能自动切换 IP。这将提高您的爬取成功率。
ISP 代理支持代理轮换。要使用此功能，您需要将端口号更改为 8000。每次新请求时，您将从代理列表中收到一个随机 IP。
代码示例
curl -x isp.oxylabs.io:8000 -U "user-USERNAME:PASSWORD" https://ip.oxylabs.io/location #pip install requests
import requests
username = 'USERNAME'
password = 'PASSWORD'
proxy = 'isp.oxylabs.io:8000'
proxies = {
"https": ('https://user-%s:%s@%s' % (username, password, proxy))
}
response=requests.get("https://ip.oxylabs.io/location", proxies=proxies)
print(response.content)//npm install axios
const axios = require("axios");
const https = require("https");
const client = axios.create({
httpsAgent: new https.Agent({
rejectUnauthorized: false,
}),
});
const username = 'USERNAME';
const password = 'PASSWORD'
client
.get("https://ip.oxylabs.io/location", {
proxy: {
protocol: "https",
host: "isp.oxylabs.io",
port: 8000,
auth: {
username: `user-${username}`,
password: password,

.then((res) => {
console.log(res.data);

.catch((err) => console.error(err));

var httpClientHandler = new HttpClientHandler {Proxy = proxy};
using var client = new HttpClient(handler: httpClientHandler, disposeHandler: true);
var result = await client.GetStringAsync("https://ip.oxylabs.io/location");
Console.WriteLine(result);如果您提供一个 country- 参数，则 IP 将从指定的国家池中选择。例如，如果您只想轮换美国代理池，请使用一个参数 country- 并在您的用户字符串中添加两个字母的国家代码 country-US 在您的用户字符串中。
