本文详细探讨了微信服务器后台如何实现高效的消息收发。从消息的接收、处理到发送，涉及到了消息队列、并发控制和数据一致性等关键技术。同时，文章还分析了服务器在高并发场景下如何保证消息的可靠性和实时性。

app.py

# -*- coding:utf-8 -*-

from flask import Flask, request
import time
import xml.etree.ElementTree as et

import hashlib

app = Flask(__name__)


@app.route('/wx/', methods=['GET', 'POST'])
def wechat():
    if request.method == 'GET':
        token = 'groundwalker'
        data = request.args
        signature = data.get('signature', '')
        timestamp = data.get('timestamp', '')
        nonce = data.get('nonce', '')
        echostr = data.get('echostr', '')

        list = [token, timestamp, nonce]
        list.sort()

        s = list[0] + list[1] + list[2]

        hascode = hashlib.sha1(s.encode('utf-8')).hexdigest()

        if hascode == signature:
            return echostr
        else:
            return ""

    if request.method == 'POST':
        xmldata = request.data
        xml_rec = et.fromstring(xmldata)

        ToUserName = xml_rec.find('ToUserName').text
        FromUserName
