微信机器人自动解析二维码

最近老婆在玩的一款游戏，有个任务是分享一个二维码图片给微信好友，然后好友按住图片点两下识别二维码就行了，她总是发给我的帐号，让我给识别，有时候忙起来给忘了，最近在学习Python，就想用Python现成的机器人做一个自动识别二维码的小软件。

直接上代码：

import itchat, time
from itchat.content import *
from PIL import Image
import zbarlight
import urllib.request
from urllib import request
import os
@itchat.msg_register([TEXT, MAP, CARD, NOTE, SHARING])
def text_reply(msg):
    msg.user.send('%s: %s' % (msg.type, msg.text))

@itchat.msg_register([PICTURE, RECORDING, ATTACHMENT, VIDEO])
def download_files(msg):
    msg.download(msg.fileName)
    ab_name = msg.fileName
    with open(ab_name, 'rb') as image_file:
        image = Image.open(image_file)
        image.load()
    codes = zbarlight.scan_codes('qrcode', image)
    a_url = codes[0].decode("utf-8")
    head = {}
    head['User-Agent'] = 'Mozilla/5.0 (Linux; Android 4.1.1; Nexus 7 Build/JRO03D) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166  Safari/535.19'
    req = request.Request(a_url, headers=head)
    response = request.urlopen(req)
    html = response.read().decode('utf-8')

    time.sleep(2)  
    with open(ab_name, 'rb') as image_file:
        image = Image.open(image_file)
        image.load()
    codes = zbarlight.scan_codes('qrcode', image)
    a_url = codes[0].decode("utf-8")
    head = {}
    head['User-Agent'] = 'Mozilla/5.0 (Linux; Android 4.1.1; Nexus 7 Build/JRO03D) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166  Safari/535.19'
    req = request.Request(a_url, headers=head)
    response = request.urlopen(req)
    html = response.read().decode('utf-8')
    return a_url

@itchat.msg_register(FRIENDS)
def add_friend(msg):
    msg.user.verify()
    msg.user.send('Nice to meet you!')

@itchat.msg_register(TEXT, isGroupChat=True)
def text_reply(msg):
    if msg.isAt:
        msg.user.send(u'@%s\u2005I received: %s' % (
            msg.actualNickName, msg.text))

itchat.auto_login(enableCmdQR=2)
itchat.run(True)

直接从https://github.com/littlecodersh/ItChat 主页上的样例复制过来，增加了下自己需要的功能，然后在Linux命令行下结合screen命令使用。

Linux命令行下如果二维码显示不全的话，把终端的字体大小调节小一点，我用的上SecureCRT。

效果图:
