如何使用telethon在电报频道中获取所有用户？

Question

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'

Answer 1

肖恩的回答不会有任何区别.

您的代码适用于较旧的Telethon版本.在新版本中,hash向GetParticipantsRequest方法添加了一个新参数.因此,您也需要hash作为参数传递.hash=0像这样添加:

result = client(GetParticipantsRequest(InputChannel(channel.chats[0].id, channel.chats[0].access_hash), filter, num, 100, 0))

请注意,hash请求的不是通道哈希.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.

这是来自官方Telethon wiki的最新示例.

Answer 2

channel = client(ResolveUsernameRequest('channel_name'))
user_list = client.iter_participants(entity=channel)
for _user in user_list:
    print(_user)

或者

user_list = client.get_participants(entity=channel)
for _user in user_list:
    print(_user)

你可以尝试下面的代码，它有效，我测试过。但我确实有一个问题，因为 Telethon 库并没有覆盖所有用户，它只覆盖了 90% 的用户。我认为它以某种方式跳过了一些......不知道为什么。

from telethon.sync import TelegramClient
from telethon.tl.functions.messages import GetDialogsRequest
from telethon.tl.types import InputPeerEmpty
import csv

api_id = 123456
api_hash = 'YOUR_API_HASH'
phone = '+111111111111'
client = TelegramClient(phone, api_id, api_hash)

client.connect()
if not client.is_user_authorized():
    client.send_code_request(phone)
    client.sign_in(phone, input('Enter the code: '))


chats = []
last_date = None
chunk_size = 200
groups=[]
 
result = client(GetDialogsRequest(
             offset_date=last_date,
             offset_id=0,
             offset_peer=InputPeerEmpty(),
             limit=chunk_size,
             hash = 0
         ))
chats.extend(result.chats)

for chat in chats:
    try:
        if chat.megagroup== True:
            groups.append(chat)
    except:
        continue

print('Choose a group to scrape members from:')
i=0
for g in groups:
    print(str(i) + '- ' + g.title)
    i+=1

g_index = input("Enter a Number: ")
target_group=groups[int(g_index)]

print('Fetching Members...')
all_participants = []
all_participants = client.get_participants(target_group, aggressive=True)

print('Saving In file...')
with open("members.csv","w",encoding='UTF-8') as f:
    writer = csv.writer(f,delimiter=",",lineterminator="\n")
    writer.writerow(['username','user id', 'access hash','name','group', 'group id'])
    for user in all_participants:
        if user.username:
            username= user.username
        else:
            username= ""
        if user.first_name:
            first_name= user.first_name
        else:
            first_name= ""
        if user.last_name:
            last_name= user.last_name
        else:
            last_name= ""
        name= (first_name + ' ' + last_name).strip()
        writer.writerow([username,user.id,user.access_hash,name,target_group.title, target_group.id])      
print('Members scraped successfully.')
