This article mainly introduces nodejs to send http requests through proxy. It has certain reference value. If you are interested, you can learn about it. I hope it can help everyone.

There may be such a demand, which requires node to be used as a web server to send http or https requests through another http/https proxy server. Without further ado, everyone knows the code directly:

var http = require(&#39;http&#39;)
var opt = {
 host:&#39;这里放代理服务器的ip或者域名&#39;,
 port:&#39;这里放代理服务器的端口号&#39;,
 method:&#39;POST&#39;,//这里是发送的方法
 path:&#39; https://www.google.com&#39;,   //这里是访问的路径
 headers:{
 //这里放期望发送出去的请求头
 }
}
//以下是接受数据的代码
var body = &#39;&#39;;
var req = http.request(opt, function(res) {
 console.log("Got response: " + res.statusCode);
 res.on(&#39;data&#39;,function(d){
 body += d;
 }).on(&#39;end&#39;, function(){
 console.log(res.headers)
 console.log(body)
 });

}).on(&#39;error&#39;, function(e) {
 console.log("Got error: " + e.message);
})
req.end();

In this way, we send an https request through the designated proxy server. Note that we use the http protocol with the proxy server here, not https. Of course, the returned result will be based on your The proxy servers vary.
