从 Twitch 的 API 获取信息以检查 discord 机器人的主播是否在线

Question

我正在尝试制作一个 Discord 机器人，以在您键入“$live”时检查 Twitch 上的主播是否在线，但我无法让它工作。我正在使用 Discord.py。我的主要问题是使用 headers 调用 API 来提供我的授权。此外，使用我目前编写的代码，它会发送此错误。我的主要问题是，我如何提供授权密钥，这样它既不会给出下面的错误，也不会说需要 OAuth。 TIA！

Ignoring exception in on_message Traceback (most recent call last): File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/client.py", line 343, in _run_event await coro(*args, **kwargs) File "main.py", line 19, in on_message response = requests.get(url, headers=headers) File "/opt/virtualenvs/python3/lib/python3.8/site-packages/requests/api.py", line 76, in get return request('get', url, params=params, **kwargs) File "/opt/virtualenvs/python3/lib/python3.8/site-packages/requests/api.py", line 61, in request return session.request(method=method, url=url, **kwargs) File "/opt/virtualenvs/python3/lib/python3.8/site-packages/requests/sessions.py", line 528, in request prep = self.prepare_request(req) File "/opt/virtualenvs/python3/lib/python3.8/site-packages/requests/sessions.py", line 456, in prepare_request p.prepare( File "/opt/virtualenvs/python3/lib/python3.8/site-packages/requests/models.py", line 317, in prepare self.prepare_headers(headers) File "/opt/virtualenvs/python3/lib/python3.8/site-packages/requests/models.py", line 449, in prepare_headers for header in headers.items(): AttributeError: 'set' object has no attribute 'items'

下面的代码。

import discord 
import os
import requests

client = discord.Client()
url = 'https://api.twitch.tv/helix/search/channels?query=whyoscar'
headers = {'client_id:' '*******************', 'Authorization:' 'Bearer **********************'}

@client.event
async def  on_ready():
  print('We have logged in as {0.user}'.format(client))

@client.event 
async def on_message(message):
  if message.author == client.user:
    return
  
  if message.content.startswith('$live'):
    response = requests.get(url, headers=headers)
    details = response.json()
    await message.channel.send(details)

client.run(os.getenv('TOKEN'))

Answer 1

根据 Twitch 论坛上的 this post，您将需要一个用户令牌，而不是应用程序令牌。

Twitch API 文档说

OAuth or App Access Token required

...但没有指定令牌需要是用户令牌。

无论如何，转到 TwitchTokenGenerator，select Bot Chat Token，使用您的 Twitch 信息登录，它应该可以工作。

Answer 2

如果您使用 OAuth 访问 Twitch API，那么流程应该是这样的：

authURL = 'https://id.twitch.tv/oauth2/token'
client_ID = 'xxx'
secret = 'xxx'

AutParams = {'client_id': client_ID,
             'client_secret': secret,
             'grant_type': 'client_credentials'
             }

AutCall = requests.post(url=authURL, params=AutParams)
access_token = AutCall.json()['access_token']

head = {
    'Client-ID' : client_ID,
    'Authorization' :  "Bearer " + access_token
    }

Answer 3

答案是，你想像这样定义你的 headers：url = 'https://api.twitch.tv/helix/search/channels?query=<channel you want to search for>&first=1' headers = {"client-id": os.getenv('CLIENT_ID_TOKEN'), "Authorization": os.getenv('ACCESS_TOKEN')} 然后把它们放在 response = requests.get(url, headers=headers) 中，然后得到 JSON 的响应并检查is_live=true 的回复。就这些！
