ItChat

Fixes

• Fix BadStatusLine and HTTP 503 errors in synccheck
• Handle malformed synccheck responses (hex-encoded strings) that were causing crashes

Note: Response format unclear — monitor for edge cases if you rely on synccheck integration.

增加了消息撤回方法，示例如下：

import itchat

itchat.auto_login(True)

user = itchat.search_friends(nickName='LittleCoder')[0]
r = user.send('hi')
msgId = r['MsgID']
r = itchat.revoke(msgId, user.userName)

itchat.run()

如果两个类互相引用将导致无法被正常回收，所以采取这种形式：

from weakref import ref

class D(object):
    def __init__(self, name):
        self.name = name
    def __del__(self):
        print('[deleted]: %s' % self.name)

class T(D):
    @property
    def pointer(self):
        return getattr(self, '_pointer', lambda: None)()
    @pointer.setter
    def pointer(self, value):
        self._pointer...

主要更改

• 更新用户、群、公众号的oop操作
• 在注册方法的返回值中增加User键值，存放发送者的类
• 将注册方法的返回值改为可以通过__getattr__访问
• 另，所有新操作不影响旧的字典的使用方式

oop操作

import itchat

user = itchat.get_friends()[0]
user.send('hi')

同样，群和公众号也是这样访问。

注册方法返回值增加User

import itchat

@itchat.msg_register(itchat.content.TEXT)
def _(msg):
    msg['User'].send('hi')

itchat.auto_login(True)
itchat.run...

获取用户头像：

import itchat, shutil

itchat.auto_login(True)

r = itchat.get_head_img(picDir='tmp.unknown')
print(r)
if 'PostFix' in r:
    shutil.move('tmp.unknown', 'tmp.%s' % r['PostFix'])

获取聊天图片：

import itchat, shutil

itchat.auto_login(True)

@itchat.msg_register(itchat.content.PICTURE)
def download(msg):
    r = msg['Text']('tmp.unknown')
    print(r)...

import itchat

def qrCallback(uuid, status, qrcode):
    if status == '400':
        itchat.logout()

itchat.auto_login(True, qrCallback=qrCallback)

if itchat.originInstance.alive:
    itchat.run()
else:
    print('qrcode timeout and exit')

你可以这样测试：

首先成功登陆一次：

import itchat
itchat.auto_login(True)

之后在手机上将该登录状态登出。（模拟各类登出）

之后重新运行登陆，你将不需要扫码直接在手机上获得登陆推送。

import itchat
itchat.auto_login(True)
itchat.send('Login without qrcode!', 'filehelper')

在上次登陆后没有通过其他途径登陆该微信的情况下，再次登录将不再需要扫码，直接收到登陆推送。

Exceptions in registered functions will now be shown in warning level. When wechat domain is not available, exceptions will also be shown in warning level.

这个问题简而言之就是退了一个用户，之后本地不会删除该用户。

这里给出一个群聊人数监控的示例：

#coding=utf8
import logging

import itchat
from itchat.content import *

logger = logging.getLogger('itchat')
groupName = u'萝卜群'
groupMemberCount = -1
groupUserName = None

itchat.auto_login(True)

group = itchat.search_chatrooms(name=groupName)[0]
if not group['MemberList']:
    logger.info('no member list detected')
    group = itchat.u...

更新了大文件的上传

这个不用多说了吧，你试试大文件就好了

更新了新的发送协议

微信更新了附件的发送协议，所以我也更新了一下
