【第五章】介面關聯 正則表示式-jsonpath模組
阿新 • • 發佈：2021-12-09
這一章節說到的是正則表示式模組跟jsonpthon模組 以及介面引數化的操作
簡單介紹一下正則表示式跟jsonpath模組
re模組是python獨有的匹配字串的模組，該模組中提供的很多功能是基於正則表示式實現的，而正則表示式是對字串進行模糊匹配，提取自己需要的字串部分，他對所有的語言都通用。注意：
- re模組是python獨有的
- 正則表示式所有程式語言都可以使用
- re模組、正則表示式是對字串進行操作

- 通過字串的replace方法分割正則提取器的值
- replace_demo_07.py

- 在excel裡面我們已經定義好的取值方式可以根據正則jsonpath或者沒有
- 優化request_utils模組底層方法get跟post
- 單獨拿一個接口出來封裝,以免導致之前的程式碼也不能執行
