Node.js做的代理转发服务器

可以代理苹果ID服务器

const http = require('http');
const https = require('https');
const client = require('https');
const fs = require('fs');
const server_options = {
  pfx: fs.readFileSync('appleid.apple.com.pfx'),
  //passphrase: 'sample'
};
const server = https.createServer(server_options, (server_req, server_res) => {
  //1：有人访问虚拟代理服务器时
  console.log(server_req.url);
  const client_options = {};
  client_options.hostname = 'appleid.apple.com.akadns.net';
  client_options.port = 443;
  client_options.method = server_req.method;
  client_options.path = server_req.url;
  client_options.headers = server_req.headers;
  client_options.headers.host = 'appleid.apple.com';
  client_options.timeout = 5000;
  //2：转发Header给目标真实的服务器
  const client_req = client.request(client_options, (client_res) => {
    //3：目标服务器返回Header
    server_res.writeHead(client_res.statusCode, client_res.headers);
    client_res.on('data', (d) => {
      //4：收到目标服务器的数据，并转发给用户
      server_res.write(d);
    });
    client_res.on('end', (d) => {
      //5：目标服务器数据发完了
      server_res.end(d);
    });
  }).on('error', (e) => {
    //6：访问目标服务器时出错
    console.error(e);
  });
  server_req.on('data', (data) => {
    //7：收到用户发来的数据，并转发给目标服务器
    console.log(data.toString());
    client_req.write(data);
  });
  server_req.on('end', (data) => {
    //8：用户数据发完了。
    client_req.end(data);
  });
});
server.on('clientError', (err, socket) => {
  socket.end('HTTP/1.1 400 Bad Request

');
});
server.on('error', (err, socket) => {
  if (err.code === 'EADDRINUSE') {
    console.log('绑定地址被占用');
  }
});
const options = {};
options['host'] = '0.0.0.0';
options['port'] = 443;
server.listen(options, () => {
  console.log('启动成功');
});

代码更新。下面这个可以记录到文件里面去

const http = require('http');
const https = require('https');
const client = require('https');
const fs = require('fs');
const zlib = require('zlib');
/*
const crypto = require('crypto');
const md5 = (str) => {
  const md5 = crypto.createHash("md5");
  md5.update(str);
  return md5.digest('hex');
};
const base64 = (str) => {
  const b = new Buffer(str);
  return b.toString('base64');
};
//*/
const rootDir = 'data';//文件保存路径
const server_options = {
  pfx: fs.readFileSync('appleid.apple.com.pfx'),
  //passphrase: 'sample'
};
const server = https.createServer(server_options, (server_req, server_res) => {
  //1：有人访问虚拟代理服务器时

  console.log(server_req.url);
  fs.writeFileSync(rootDir + '/request_header-' + url_encoded, JSON.stringify(server_req.headers));
