nodejs Websoket wss error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

错误提示如下：

Error: write EPROTO 140052867975040:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:../deps/openssl/openssl/ssl/s23_clnt.c:827:
 
    at _errnoException (util.js:1022:11)
    at WriteWrap.afterWrite [as oncomplete] (net.js:880:14) code: 'EPROTO', errno: 'EPROTO', syscall: 'write' }

最后发现是因为https使用的端口是443，而http使用的端口是80，这里要切换过来

代码如下：

var content = querystring.stringify("id=111111");
var options = {
  host: '127.0.0.1',
  hostname: "www.baidu.com",
  //port: 80,		//http
  port: 443,	//https
  path: action,
  method: 'POST',
  headers: {
	'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'/* ,
	'Content-Length': send.length */
  }
};
var req = http.request(options, function (res) {
	//返回数据流
	var body="";
	res.setEncoding('utf8');
	res.on('data', function (chunk) {
		// console.log('BODY: ' + chunk);
		body += chunk;
	});
	res.on('end', function(){
		// console.log("body = "+body);
		if(body.length>0){
			try{
				//逻辑处理
			} catch(e){
				console.log(e);
			}
		}
	});
});
req.on('error', function (e) {
  console.log('problem with request: ' + e.message);
});
req.write(content);
req.end();
