按照課程上面進行測試，雖然評論成功了，但是沒有打印出?res.on('data',function(chunk){? ? ? ? console.log(Buffer.isBuffer(chunk));? ? ? ? console.log(typeof chunk);? ? });這個事件中的數(shù)據(jù)，請問是什么原因呢？源代碼：var http =require('http');var querystring =require('querystring');var postData = querystring.stringify({? ? content:'不錯不錯不錯',? ? cross_post:1,? ? belongId:2862414});var options ={? ? hostname: 'v.yinyuetai.com',? ? port:80,? ? path:'/video/2862414',? ? method:'POST',? ? headers:{? ? ? ?
