Python 3.x 无法使用fbchat登录facebook

我正在尝试创建一个python程序来发送fb消息，但无法使用以下代码登录

import fbchat 
from getpass import getpass

username = input("username: ")
client = fbchat.Client(username, getpass())
print(client.getSessions)
no_of_friends = 1 #int(("Number of friends: ")) 

for i in range(no_of_friends): 
    
    name = str(input("Name: "))
    
    friends = client.searchForUsers(name)  # return a list of names
    
    friend = friends[0]
    
    msg = input("Message: ") 
    
    sent = client.send(fbchat.models.Message( msg), thread_id = int(friend.uid))
    
    if sent: 
        
        print("Message sent successfully!")

它给出了以下错误

Attempt #1 failed, retrying
Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/fbchat/_client.py", line 205, in login
    self._state = State.login(
  File "/usr/local/lib/python3.8/dist-packages/fbchat/_state.py", line 151, in login
    return cls.from_session(session=session)
  File "/usr/local/lib/python3.8/dist-packages/fbchat/_state.py", line 190, in from_session
    revision = int(r.text.split('"client_revision":', 1)[1].split(",", 1)[0])
IndexError: list index out of range

试试这个，我已经测试过了，效果非常好。你需要添加用户代理

这听起来像是该库维护人员的错误报告……如何使用Python fbchat使用messenger在Facebook上发送消息？
