Requsts方法 -- Blog流程類進行關聯

一、接口封裝關聯

1.有些接口常常會用到好比登陸的接口，這時候咱們能夠每一個接口都封裝成一個方法，如：登陸、保存草稿、發帖、刪帖，這四個接口就能夠寫成四個方法
2.接口封裝好了後，後面咱們寫用例那就直接調用封裝好的接口就好了，有些參數，能夠參數化，如保存草稿的 title 和 body 兩個參數是動態的。
3.像這種流程類的接口，後面的會依賴前面的，就能夠用 session 關聯起來
4.保存如下腳本 

import requests
#禁用安全請求警告
from requests.packages.urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
"""
1.因爲登陸時候是多加 2 個 cookie，咱們能夠先用 get 方法打開登陸首頁，獲取部分 cookie
2.再把登陸須要的 cookie 添加到 session 裏
3.添加成功後，隨便編輯正文和標題保存到草稿箱
