如何使用 Telethon 创建公共/私人频道？我在官方文档中没有找到这个信息。

【问题讨论】：

【解决方案1】：

您可以使用此过程来创建私人频道（也可以通过为其分配用户名将其公开）：

from telethon.tl.functions.channels import CreateChannelRequest, CheckUsernameRequest, UpdateUsernameRequest
from telethon.tl.types import InputChannel, InputPeerChannel
createdPrivateChannel = client(CreateChannelRequest("title","about",megagroup=False))

#if you want to make it public use the rest
newChannelID = createdPrivateChannel.__dict__["chats"][0].__dict__["id"]
newChannelAccessHash = createdPrivateChannel.__dict__["chats"][0].__dict__["access_hash"]
desiredPublicUsername = "myUsernameForPublicChannel"
checkUsernameResult = client(CheckUsernameRequest(InputPeerChannel(channel_id=newChannelID, access_hash=newChannelAccessHash), desiredPublicUsername))
if(checkUsernameResult==True):
    publicChannel = client(UpdateUsernameRequest(InputPeerChannel(channel_id=newChannelID, access_hash=newChannelAccessHash), desiredPublicUsername))

我如何创建邀请链接？
请深入研究库 API，以便您可以找到所需的任何内容：exportInviteResult = client(ExportInviteRequest(InputPeerChannel(channel_id=createdSupergroup.__dict__["chats"][0].__dict__["id" ], access_hash=createdSupergroup.__dict__["chats"][0].__dict__["access_hash"]))
从 telethon.tl.functions.channels 导入 ExportInviteRequest
现在不行了：from telethon.tl.functions.channels import ExportInviteRequest ImportError: cannot import name 'ExportInviteRequest' from 'telethon.tl.functions.channels'
谢谢。一个好主意是使用 await（和异步模式）。

【解决方案2】：

上面的片段可以工作，但在同步模式下，asyncio 调用如下：

from telethon import TelegramClient    
from telethon.tl.functions.channels import InviteToChannelRequest, CreateChannelRequest, CheckUsernameRequest, UpdateUsernameRequest
from telethon.tl.types import InputPeerChannel
    

tm = TelegramClient(username, api_id, api_hash)
tm.start(user_phone)

async def proc():
    created_private_channel = await tm(CreateChannelRequest(
        "Channel Title",
        "Channel description",
        broadcast=True, megagroup=False))
    new_channel_id = created_private_channel.created_private_channel.chats[0].id
    new_channel_access_hash = created_private_channel.chats[0].access_hash
    check_channelname_result = await tm(CheckUsernameRequest(
        InputPeerChannel(channel_id=new_channel_id,
                         access_hash=new_channel_access_hash), desired_ch_name))
    if check_channelname_result:
        update_response = await tm(UpdateUsernameRequest(
            InputPeerChannel(channel_id=new_channel_id,
                             access_hash=new_channel_access_hash), desired_ch_name))
        print(f'update_response={update_response}')
    else:
        print(f'channelname={desired_ch_name} already taken')

tm.loop.run_until_complete(proc())
