Reverse proxy?

[koteesy]

Hello, for example, i have few proxies:

const proxies = [
      '51.222.21.93:80',
      '107.1.80.135:80',
      '34.234.164.65:80'
];

And i have anyProxy server on 127.0.0.1:5050

I want do something like:

Request come to 127.0.0.1:5050 then i'll get random proxy from my proxy list, then anyProxy request with that proxy.

How i can implement that?

module.exports = {
  summary: 'a rule to inject proxy',
  * beforeSendRequest (requestDetail) {
    const proxies = [
      '51.222.21.93:80',
      '107.1.80.135:80',
      '34.234.164.65:80'
    ];

    const item = proxies[Math.floor(Math.random()*proxies.length)];

    // Where i can put my proxy?

    console.log(item);

    return null;
  },
};

你可以了解一下node的 http模块的request类。
根据anyproxy的源码我发现，请求远程服务器使用的是http.request，requestDetail.requestOptions就是http.request 和https.request 的options。
http.request 示例
const req = https.request(options, res => {

})
req.end()

查询了相关文档https://www.cnblogs.com/ference/p/4014210.html，可以如下实现
http相关实现方法：
module.exports = {
summary: 'a rule to inject proxy',

• beforeSendRequest (requestDetail) {
  let Options=requestDetail.requestOptions；
  //修改Options ，add proxyOptions
  ......
  requestDetail.requestOptions=Options;
  return requestDetail
  },
  };

https根据文档介绍自行实现代理类并修改Options即可。

另一种实现方法更为简单，直接自己使用请求库（如Axios、Superagent、ruquest等）进行请求，并直接返回
const request = require('request'),
module.exports = {
summary: 'a rule to inject proxy',

• beforeSendRequest (requestDetail) {

// 要访问的目标地址
let url = requestDetail.url
let method = requestDetail.requestOptions.method
// 代理服务器ip和端口
let proxy_ip = '47.115.36.94';
let proxy_port = 16816;

// 完整代理服务器url
let proxy = util.format('http://%s:%d', proxy_ip, proxy_port);

function req () {
return new Promise((resolve, reject) => {
// 发起请求
request({
url: url,
method: 'GET',
data: {
.....
},
proxy: proxy,
headers: {
....
},
encoding: null, // 方便解压缩返回的数据
}, function (error, res, body) {
//.....todo....
resolve(body)

    });
})

}

let response=await req();

return {
response: response
};
},
};
