python3+requests：使用类封装接口测试脚本

前言：接口测试用例较多，我们不可能每个用例都写一次requests,get或者requests,post等，所以对共用方法要进行封装处理

第一次修改：将get请求和post请求单独定义出来，使用过程中根据不同类型的请求直接调用对应的方法

 import requests
 import json

 def send_post(url,data,headers):
     response = requests.post(url=url,data=data,headers=headers).json()
     return json.dumps(response,sort_keys=True,indent=4)

 def send_get(url,data,headers):
     response = requests.get(url=url,data=data,headers=headers).json()
     return json.dumps(response,sort_keys=True,indent=4)

 def run_main(url,headers,method,data=None):
     respose = None
     if method == 'GET':
         respose = send_get(url,data,headers)
     else:
         respose = send_post(url,data,headers)
     return respose

 url = 'https://...'
 headers = {'Content-Type': 'application/x-www-form-urlencoded'}
 print(run_main(url,headers,method='POST'))

第二次修改：用class进行封装，主函数中创建一个实例run来调用类中的方法

 import requests
 import json
 class Runmain:
     def send_post(self,url,data,headers):
         response = requests.post(url=url,data=data,headers=headers).json()
         return json.dumps(response,sort_keys=True,indent=)

     def send_get(self,url,params,headers):
         response = requests.get(url=url,params=params,headers=headers).json()
         return json.dumps(response,sort_keys=True,indent=)

     def run_main(self,url,params,data,headers,method):
         respose = None
         if method == 'GET':
             respose = self.send_get(url,params,headers)
         else:
             respose = self.send_post(url,data,headers)
         return respose

 if __name__ == '__main__':
     run = Runmain()
     url = 'https://...'
     headers = {'Content-Type': 'application/x-www-form-urlencoded'}
     print(run.run_main(url,params=None,data=None,headers=headers,method='POST'))

第三次修改：第二次修改，每次都需要实例化后再调用对应的方法；

改进办法：使用__init__方法实现：只要实例化类时候就会调用__init__方法

 import requests
 import json
 class Runmain:
     def __init__(self,url,params,data,headers,method):
         self.response = self.run_main(url,params,data,headers,method)

     def send_post(self,url,data,headers):
         response = requests.post(url=url,data=data,headers=headers).json()
         return json.dumps(response,sort_keys=True,indent=)

     def send_get(self,url,params,headers):
         response = requests.get(url=url,params=params,headers=headers).json()
         return json.dumps(response,sort_keys=True,indent=)

     def run_main(self,url,params,data,headers,method):
         respose = None
         if method == 'GET':
             respose = self.send_get(url,params,headers)
         else:
             respose = self.send_post(url,data,headers)
         return respose

 if __name__ == '__main__':
     url = 'https://...'
     headers = {'Content-Type': 'application/x-www-form-urlencoded'}
     run = Runmain(url,params=None,data=None,headers=headers,method='POST')
     print(run.response)
