附上代码给大家参考

var req = http.request(options,function (res) {

req.on('error',function (e) {

req.write(postData);
req.end();

运行时报错：Error: write EPROTO 101057795:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:op；

发现是由于我前面写的是 var http = ‘https’，端口号写的是 port：80；

而实际上 https 的端口号应该是如代码中的 ‘port’：443
