如何愉快的填写问卷星

从业务开发，了解http本质。

问卷星代刷方法:

python+selenium 通过自动化测试工具正常填写，方法低效，容易出现安全检测（本文不讲）。
post请求，模拟包发送，简单快捷，跳过安全检测，缺点:需要对http协议有所了解，对请求包进行分析。

开始

设计问卷，我将从测试简单的单选，多选，填空上进行请求包分析。

选择一款带有右键检查的浏览器，本文采用google浏览器。

测试开始，准备对请求包进行解析，此处点击提交按钮后，需要在反应过程快速停止抓包，否则会被响应包覆盖：

接下来我们点击请求包，查看请求包内容将有惊人发现:

我们讲解一些内容，为python模拟post请求提供支撑。

Request URL:实际提交的URL路径

Status Code:状态码和原因

Cookie：小甜饼记录浏览器与服务器交互的状态信息

Host：主机域名或者地址

Referer:引用地址防盗链

User-Agent：代理主机（模仿）

下拉到页尾，我们将看到最重要的部分-请求内容

我们仔细看会发现，与我们在填写问卷时，所选择，多选，填空内容似乎有所联系。因此，这里便是我们对post请求的切入点。我们也很容易发现其中规律 :

题号x后面+$+选项y+结尾}

接下来我们模拟代码

引用包（代码注释部分需要注意 host,Referer,Cookie）:

requests：网络库，进行网络请求
random：随机数算法库，进行随机选择
fake_useragent：虚拟用户代理，模仿浏览器请求
urllib3:网络库

模仿随机选择代码

此处我们更改url地址为request请求地址，其余根据设置内容，对下面循环进行定制

运行代码10表示正确
