python - 请求——如何判断您是否收到了成功消息？

Question

我的问题与this one密切相关.

我正在使用 Requests 库访问 HTTP 端点。我想检查响应是否成功。

我目前正在这样做:

r = requests.get(url)
if 200 <= response.status_code <= 299:
    # Do something here!

除了对 200 到 299 之间的值进行那种丑陋的检查之外，有没有我可以使用的速记？

The response has an ok property .使用那个:

if response.ok:
    ...

实现只是围绕 Response.raise_for_status 的尝试/异常(exception)，它本身会检查状态代码。

@property
def ok(self):
    """Returns True if :attr:`status_code` is less than 400, False if not.

    This attribute checks if the status code of the response is between
    400 and 600 to see if there was a client error or a server error. If
    the status code is between 200 and 400, this will return True. This
    is **not** a check to see if the response code is ``200 OK``.
    """
    try:
        self.raise_for_status()
    except HTTPError:
        return False
    return True
