Requests方法 -- Blog流程类进行关联

1、接口封装关联

1.有些接口经常会用到比如登录的接口，这时候我们可以每个接口都封装成一个方法，如：登录、保存草稿、发帖、删帖，这四个接口就可以写成四个方法
2.接口封装好了后，后面我们写用例那就直接调用封装好的接口就行了，有些参数，可以参数化，如保存草稿的 title 和 body 两个参数是动态的。
3.像这种流程类的接口，后面的会依赖前面的，就可以用 session 关联起来
4.保存以下脚本 

import requests
#禁用安全请求警告
from requests.packages.urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
"""
1.由于登录时候是多加 2 个 cookie，我们可以先用 get 方法打开登录首页，获取部分 cookie
2.再把登录需要的 cookie 添加到 session 里
3.添加成功后，随便编辑正文和标题保存到草稿箱
