需要用到2个库，
requestsocks5-http-client/lib/Agent/
或
socks5-https-client/lib/Agentsocks5-http-client/lib/Agent/socks5-https-client/lib/Agent因为一些已知原因，有时候，http.request请求无法拿到数据，
首先想到的是proxy，其次是socket5.有了以上两个库，接下来的代码超级简单。
const request = require('request');
var httpAgent = require('socks5-http-client/lib/Agent');
var httpsAgent = require('socks5-https-client/lib/Agent');

var Agent = /^https/.test(url) ? httpsAgent : httpAgent;
request({

url: url,

strictSSL: false,

agentClass: Agent
}, function(err, res) {

console.log(err||res.body,res.statusCode,res.headers);
});


const request = require('request');
var httpAgent = require('socks5-http-client/lib/Agent');
var httpsAgent = require('socks5-https-client/lib/Agent');

var Agent = /^https/.test(url) ? httpsAgent : httpAgent;
request({

url: url,

strictSSL: false,

agentClass: Agent
}, function(err, res) {

console.log(err||res.body,res.statusCode,res.headers);
});

当然，也可以修改代理地址：
request({

url: url,

strictSSL: false,

agentClass: Agent,

agentOptions: {

socksHost: 'localhost', // Defaults to 'localhost'.

socksPort: 1080, // Defaults to 1080.

}
}, function(err, res) {

console.log(err||res.body,res.statusCode,res.headers);
});

request({

url: url,

strictSSL: false,

agentClass: Agent,

agentOptions: {

socksHost: 'localhost', // Defaults to 'localhost'.

socksPort: 1080, // Defaults to 1080.

}
}, function(err, res) {

console.log(err||res.body,res.statusCode,res.headers);
});
我有点不理解的地方是：
我使用http.request 的时候，需要自己添加各种headers，来满足请求不报错，而request库却不用写任何headers。
