前言：介面測試用例較多，我們不可能每個用例都寫一次requests,get或者requests,post等，所以對共用方法要進行封裝處理

第一次修改：將get請求和post請求單獨定義出來，使用過程中根據不同型別的請求直接呼叫對應的方法

 1 import requests
 2 import json
 3 
 4 def send_post(url,data,headers):
 5     response = requests.post(url=url,data=data,headers=headers).json()
 6     return json.dumps(response,sort_keys=True,indent=4)
 7 
 8 def send_get(url,data,headers):
 9     response = requests.get(url=url,data=data,headers=headers).json()
10     return json.dumps(response,sort_keys=True,indent=4)
11 
12 def run_main(url,headers,method,data=None):
13     respose = None
14     if method == 'GET':
15         respose = send_get(url,data,headers)
16     else:
17         respose = send_post(url,data,headers)
18     return respose
19 
20 url = 'https://...'
21 headers = {'Content-Type': 'application/x-www-form-urlencoded'}
22 print(run_main(url,headers,method='POST'))

第二次修改：用class進行封裝，主函式中建立一個例項run來呼叫類中的方法

 1 import requests
 2 import json
 3 class Runmain:
 4     def send_post(self,url,data,headers):
 5         response = requests.post(url=url,data=data,headers=headers).json()
 6         return json.dumps(response,sort_keys=True,indent=4)
 7 
 8     def send_get(self,url,params,headers):
 9         response = requests.get(url=url,params=params,headers=headers).json()
10         return json.dumps(response,sort_keys=True,indent=4)
11 
12     def run_main(self,url,params,data,headers,method):
13         respose = None
14         if method == 'GET':
15             respose = self.send_get(url,params,headers)
16         else:
17             respose = self.send_post(url,data,headers)
18         return respose
19 
20 if __name__ == '__main__':
21     run = Runmain()
22     url = 'https://...'
23     headers = {'Content-Type': 'application/x-www-form-urlencoded'}
24     print(run.run_main(url,params=None,data=None,headers=headers,method='POST'))

第三次修改：第二次修改，每次都需要例項化後再呼叫對應的方法；

改進辦法：使用__init__方法實現：只要例項化類時候就會呼叫__init__方法

 1 import requests
 2 import json
 3 class Runmain:
 4     def __init__(self,url,params,data,headers,method):
 5         self.response = self.run_main(url,params,data,headers,method)
 6 
 7     def send_post(self,url,data,headers):
 8         response = requests.post(url=url,data=data,headers=headers).json()
 9         return json.dumps(response,sort_keys=True,indent=4)
10 
11     def send_get(self,url,params,headers):
12         response = requests.get(url=url,params=params,headers=headers).json()
13         return json.dumps(response,sort_keys=True,indent=4)
14 
15     def run_main(self,url,params,data,headers,method):
16         respose = None
17         if method == 'GET':
18             respose = self.send_get(url,params,headers)
19         else:
20             respose = self.send_post(url,data,headers)
21         return respose
22 
23 if __name__ == '__main__':
24     url = 'https://...'
25     headers = {'Content-Type': 'application/x-www-form-urlencoded'}
26     run = Runmain(url,params=None,data=None,headers=headers,method='POST')
27     print(run.response)
