如何使用 Telethon 在電報頻道中獲取所有用戶？

Question

我是 Telethon 和 python 的新手。 我已經在 python3 中安裝了 Telethon，我想獲取電報頻道或組的所有成員。 我在互聯網上搜索了很多，發現下面的代碼。 我真的很努力地理解它。電報文檔不足以做到這一點。 有更好的解決方案嗎？

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))

但我收到此錯誤。 我錯過了什么？

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

肖恩的回答沒有任何區別。

您的代碼適用於較舊的 Telethon 版本。 在新版本中，新的參數hash添加到GetParticipantsRequest方法。 因此，您也需要將hash作為參數傳遞。 添加hash=0像這樣：

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

請注意，請求的hash不是通道哈希。 它是根據您已經知道的參與者計算的特殊哈希，因此 Telegram 可以避免重新發送整個內容。 您可以將其保留為 0。

這是來自 Telethon 官方 wiki 的最新示例。

Answer 2

我認為您可以在新版本的Telethon使用此代碼

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

我用Telethon V0.19 ，但以前的版本幾乎相同

Answer 3

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

要么

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

Answer 4

你可以試試下面的代碼，它有效，我測試過。 但我確實有一個問題，因為 Telethon 庫不會額外增加所有用戶，它只會額外增加 90% 的用戶。 我認為它以某種方式跳過了一些......不知道為什么。

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.')

Answer 5

使用client.invoke()而不是client() 。

你可以參考官方指南。
