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

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 = None14     if method == 'GET':15         respose = send_get(url,data,headers)16     else:17         respose = send_post(url,data,headers)18     return respose19 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进行封装，主函数中创建一个实例run来调用类中的方法

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 = None14         if method == 'GET':15             respose = self.send_get(url,params,headers)16         else:17             respose = self.send_post(url,data,headers)18         return respose19 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

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 = None17         if method == 'GET':18             respose = self.send_get(url,params,headers)19         else:20             respose = self.send_post(url,data,headers)21         return respose22 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)
