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
