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  2 import json  3 
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 
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 
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 
url = 'https://...'
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

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 
    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 
    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 
if __name__ == '__main__': 21     run = Runmain() 22     url = 'https://...'
    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

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 
 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 
    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 
    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 
if __name__ == '__main__': 24     url = 'https://...'
    headers = {'Content-Type': 'application/x-www-form-urlencoded'} 26     run = Runmain(url,params=None,data=None,headers=headers,method='POST') 27     print(run.response)
