python实现比对美团接口返回数据和本地mongo数据是否一致示例

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 hashlib
import time
import requests
def 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 result
def 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 result
def 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
