python - 使用 Python 3.x 从网站中提取 JSON 数据

Question

我正在尝试从网站提取一些 JSON 数据，用于我为 Discord 机器人制作的一个小程序。代码目前看起来像:

if message.content.startswith("!jsontest"):
    import requests
    data = requests.get('http://schoolido.lu/api/cards/799/').json()
    print(data)

我也尝试过使用 urllib.request.urlopen，但无论使用哪种方法，我都会收到 403 错误。这是输出:

   Traceback (most recent call last):
  File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\discord\client.py", line 259, in _run_event
    yield from getattr(self, event)(*args, **kwargs)
  File "C:/Users/user/Desktop/Bot.py", line 177, in on_message
    response = ur.urlopen("http://schoolido.lu/api/cards/799/")
  File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\urllib\request.py", line 162, in urlopen
    return opener.open(url, data, timeout)
  File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\urllib\request.py", line 471, in open
    response = meth(req, response)
  File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\urllib\request.py", line 581, in http_response
    'http', request, response, code, msg, hdrs)
  File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\urllib\request.py", line 509, in error
    return self._call_chain(*args)
  File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\urllib\request.py", line 443, in _call_chain
    result = func(*args)
  File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\urllib\request.py", line 589, in http_error_default
    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 403: Forbidden

是我遗漏了什么，还是代码有误？我已经尝试了很多来自 SO 的其他示例，但它们都没有做任何不同的事情，即我仍然得到 403。

首先尝试将其转换为 Python 字典，如下所示。它应该有效。

if message.content.startswith("!jsontest"):
import requests
import json
data = requests.get('http://schoolido.lu/api/cards/799/')
text = data.text
dictionary = json.loads(text)
print(data)
