灌水案例

node.js实现灌水

###自动评论 - get是对request进行了封装，所以可以使用http的request - 原理：通过cookie，实现用户自动评论，headers中的cookie很重要 - `path: '/course/docomment'` - `'Content-Length': postData.length`

var http = require('http');
var querystring = require('querystring');         //加载序列化模块

var postData = querystring.stringify({            
    'content': '妹子，求安慰',                    //灌水内容
    'mid': 8837                                   //FormData中的mid(课程号)
})

var options = {
    hostname: 'www.imooc.com',
    port: 80,
    path: '/course/docomment',                    //评论路径
    method: 'POST',
    headers: {    
       'Accept': 'application/json, text/javascript, */*; q=0.01',
       'Accept-Encoding': 'gzip, deflate',
       'Accept-Language': 'zh-CN',
       'Cache-Control': 'no-cache',
       'Connection': 'Keep-Alive',
       'Content-Length': postData.length,        //这里要修改为评论内容的长度
       'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
       'Cookie': 'imooc_uuid=492ffbb1-7380-47b0-86ee-9a8bee1e88a8; imooc_isnew_ct=1480587158;       Hm_lvt_f0cfcccd7b1393990c78efdeebff3968=1483414974,1483587044,1483696939,1483732760; imooc_isnew=2; loginstate=1; apsid=Q0OTQ2MWJjNjczOWMxZjdjOWRiZTJhZTg4YmYxN2EAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAANDM5OTQzMQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAxNDc3ODM1NzAxQHFxLmNvbQAAAAAAAAAAAAAAAAAAADM3MThmYmU3NzkzZWI3ZGJiOGI3NzZmMDU2MWI0Zjlh2oZnWNqGZ1g%3DOG; last_login_username=1477835701%40qq.com; IMCDNS=0; cvde=586f6b26ebe6d-150; Hm_lpvt_f0cfcccd7b1393990c78efdeebff3968=1483800760; PHPSESSID=rmj1gld73uuir54oqbkh2vihi5; jwplayer.qualityLabel=¸ßÇå; jwplayer.volume=21',

       'X-Requested-With': 'XMLHttpRequest'
    }
}

var req = http.request(options, function(res){
       console.log('Status:' + res.statusCode);
       console.log('headers:' + JSON.stringify(res.headers));
       res.on('data', function(chunk){
          console.log(Buffer.isBuffer(chunk));
          console.log(typeof chunk);
       })
       res.on('end', function(){
        console.log('评论完毕');
       })
})

req.on('error', function(e){
    console.log('Error:'+e.message)
})
req.write(postData);
req.end();

headers的获取

• 打开浏览器控制台，Network
• 在任意网站评论，点击提交
• 会出现一个数据请求，点开后，即可找到headers
