我是telethon和python的新手。我已经在python3中安装了telethon，我希望获得电报频道或小组的所有成员。我在互联网上搜索了很多，发现下面的代码。我正在努力去理解它.Telegram文档还不足以做到这一点。有更好的解决方案吗？
from telethon import TelegramClient
from telethon.tl.functions.contacts import ResolveUsernameRequest
from telethon.tl.functions.channels import GetAdminLogRequest
from telethon.tl.functions.channels import GetParticipantsRequest
from telethon.tl.types import ChannelParticipantsRecent
from telethon.tl.types import InputChannel
from telethon.tl.types import ChannelAdminLogEventsFilter
from telethon.tl.types import InputUserSelf
from telethon.tl.types import InputUser
# These example values won't work. You must get your own api_id and
# api_hash from https://my.telegram.org, under API Development.
api_id = 12345
api_hash = '8710a45f0f81d383qwertyuiop'
phone_number = '+123456789'
client = TelegramClient(phone_number, api_id, api_hash)
client.session.report_errors = False
client.connect()
if not client.is_user_authorized():
client.send_code_request(phone_number)
client.sign_in(phone_number, input('Enter the code: '))
channel = client(ResolveUsernameRequest('channelusername')) # Your channel username
user = client(ResolveUsernameRequest('admin')) # Your channel admin username
admins = [InputUserSelf(), InputUser(user.users[0].id, user.users[0].access_hash)] # admins
admins = [] # No need admins for join and leave and invite filters
filter = None # All events
filter = ChannelAdminLogEventsFilter(True, False, False, False, True, True, True, True, True, True, True, True, True, True)
cont = 0
list = [0,100,200,300]
for num in list:
result = client(GetParticipantsRequest(InputChannel(channel.chats[0].id, channel.chats[0].access_hash), filter, num, 100))
for _user in result.users:
print( str(_user.id) + ';' + str(_user.username) + ';' + str(_user.first_name) + ';' + str(_user.last_name) )
with open(''.join(['users/', str(_user.id)]), 'w') as f: f.write(str(_user.id))
但是我收到了这个错误。我错过了什么？
Traceback (most recent call last):
File "run.py", line 51, in <module>
result = client(GetParticipantsRequest(InputChannel(channel.chats[0].id, channel.chats[0].access_hash), filter, num, 100))
TypeError: __init__() missing 1 required positional argument: 'hash'
答案 0 :(得分：5)
您的代码适用于较旧的Telethon版本。在新版本中，hash方法添加了新参数GetParticipantsRequest。因此，您还需要将hash作为参数传递。像这样添加hash=0：
result = client(GetParticipantsRequest(InputChannel(channel.chats[0].id, channel.chats[0].access_hash), filter, num, 100, 0))
请注意，请求的hash不是频道哈希。这是根据您已经了解的参与者计算的特殊哈希值，因此Telegram可以避免重新发送整个内容。你可以把它留到0。
Here是官方Telethon维基的最新示例。

我认为您可以在新版Telethon
from telethon import TelegramClient
from telethon.tl.functions.channels import GetParticipantsRequest
from telethon.tl.functions.channels import GetFullChannelRequest
from telethon.tl.types import ChannelParticipantsSearch
api_id = XXXXX
api_hash = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
phone_number = '+98XXXXXXXX'
################################################
channel_username = 'tehrandb'
################################################
client = TelegramClient('session_name',api_id,api_hash)
assert client.connect()
if not client.is_user_authorized():
client.send_code_request(phone_number)
me = client.sign_in(phone_number, input('Enter code: '))
# ---------------------------------------
offset = 0
limit = 200
my_filter = ChannelParticipantsSearch('')
all_participants = []
while_condition = True
# ---------------------------------------
channel = client(GetFullChannelRequest(channel_username))
while while_condition:
participants = client(GetParticipantsRequest(channel=channel_username, filter=my_filter, offset=offset, limit=limit, hash=0))
all_participants.extend(participants.users)
offset += len(participants.users)
if len(participants.users) < limit:
while_condition = False
我使用Telethon V0.19，但之前的版本几乎相同
答案 2 :(得分：1)
channel = client(ResolveUsernameRequest('channel_name'))
user_list = client.iter_participants(entity=channel)
for _user in user_list:
print(_user)
或
user_list = client.get_participants(entity=channel)
for _user in user_list:
print(_user)

使用client.invoke()代替client()。
您可以参考official guide。
答案 4 :(得分：0)
你可以试试下面的代码，它有效，我测试过。但我确实有一个问题，因为 Telethon 库不会额外增加所有用户，它只会额外增加 90% 的用户。我认为它以某种方式跳过了一些......不知道为什么。
