這個微信接口還挺有意思的，隨便玩了下，可以備份消息，群發(fā)消息好多，不過貌似有些功能還有些bug，寫了一段群發(fā)消息的代碼，可以做個群聊機(jī)器人：

import itchat

itchat.auto_login(hotReload=True)
chatrooms = itchat.get_chatrooms(update=True, contactOnly=True)
chatroom_ids = [c['UserName']for c in chatrooms]
print('正在監(jiān)測的群聊：', len(chatrooms), '個')
print(' '.join([item['NickName'] for item in chatrooms]))
print(chatroom_ids)


@itchat.msg_register(itchat.content.TEXT, isGroupChat=True)
def msg_reply(msg):
    default = '倪幸福啊！'
    if msg['FromUserName'] in chatroom_ids:
        return default
    else:
        return None


itchat.run()

實(shí)現(xiàn)了一個自動回復(fù)特定群消息的功能，不過如果連上圖靈機(jī)器人就可以更智能一點(diǎn)了，懶得搞了，還有msg那一長串誰看下去啊- -還有很多功能以后再玩吧。

實(shí)現(xiàn)爬好友圖片功能：

import PIL.Image as Image

itchat.auto_login(hotReload=True)
friends = itchat.get_friends(update=True)[0:]
user = friends[0]['UserName']

num = 0
for i in friends:
    img = itchat.get_head_img(userName=i['UserName'])
    fileImage = open('F:/test/myenviron' + "/" + str(num) + ".jpg", 'wb')
    fileImage.write(img)
    fileImage.close()
    num += 1

ls = os.listdir('F:/test/myenviron')
each_size = int(math.sqrt(float(640*640)/len(ls)))
lines = int(640/each_size)
image = Image.new('RGBA',(640,640))

x = 0
y = 0
for i in range(0,len(ls)+1):
    try:
        img = Image.open('F:/test/myenviron' + "/" + str(i) + ".jpg")
    except IOError:
        print("Error")
    else:
        img = img.resize((each_size, each_size), Image.ANTIALIAS)
        image.paste(img, (x*each_size, y*each_size))
        x += 1
        if x == lines:
            x = 0
            y += 1

image = image.convert('RGB')
image.save('F:/test/myenviron' + "/" + 'all.jpg')
itchat.send_image('F:/test/myenviron' + "/" + 'all.jpg', 'filehelper')

圖靈機(jī)器人

import itchat
import requests
然后定義一個向圖靈機(jī)器人發(fā)送消息并接受機(jī)器人回復(fù)的消息，并將從圖靈機(jī)器人接受到的消息return返回。


def get_response(_info):
    print(_info)                                       # 從好友發(fā)過來的消息
    api_url = 'http://www.tuling123.com/openapi/api'   # 圖靈機(jī)器人網(wǎng)址
    data = {
        'key': '485712b8079e44e1bc4af10872b08319',     # 如果這個 apiKey 如不能用，那就注冊一次
        'info': _info,                                 # 這是我們從好友接收到的消息 然后轉(zhuǎn)發(fā)給圖靈機(jī)器人
        'userid': 'wechat-robot',                      # 這里你想改什么都可以
    }
    r = requests.post(api_url, data=data).json()       # 把data數(shù)據(jù)發(fā)
    print(r.get('text'))                               # 機(jī)器人回復(fù)給好友的消息
    return r
 

三、定義消息回復(fù)

@itchat.msg_register(itchat.content.TEXT)
def text_reply(msg):
    return "【我是天才^_^】" + get_response(msg["Text"])["text"]
　
/這里是關(guān)閉群消息的，針對群消息可以再加一欄/

四、掃碼登錄，大功告成。

if __name__ == '__main__':
    itchat.auto_login(hotReload=True)                  # hotReload = True, 保持在線，下次運(yùn)行代碼可自動登錄
    itchat.run()
