本文实例讲述了python实现比对美团接口返回数据和本地mongo数据是否一致。分享给大家供大家参考，具体如下：

应用背景：美团平台商品的上下架状态、库存、售价，和mongo库存储的是否一致。

tools文件内容

# -*- coding: utf-8 -*-import hashlibimport timeimport requestsdef get_md5(string):#返回字符串md5加密后的串 hl = hashlib.md5() hl.update(string.encode('utf-8')) return hl.hexdigest()def get_tamp():#获取当前的时间戳 t = time.time() return int(t)def req_get_result(api_url,api_data):#get方法请求函数 req_get = requests.get(api_url,api_data) result = req_get.json() return resultdef req_post_result(api_url,api_data):#post方法请求函数 req_post = requests.post(api_url,data=api_data) result = req_post.json() return resultdef file_edit(file_name,wr_str):#写入txt文件 f1 = open(r'D:\%s.txt'%file_name,'a') f1.write(wr_str+'\n') f1.close()def param_sort(param_dict):#传入字典,返回排序后并且连接好的字符串 keys_list = sorted(param_dict.keys()) rb_str = '' for k in keys_list: key_value = k + '=' + str(param_dict[k]) rb_str = rb_str + key_value +'&' rb_str = rb_str[0:-1] #不保留字符串末尾的& return rb_str

下面是主逻辑
