python - FCM API 'Bad request 400' 错误

Question

我正在尝试通过新的 FCM api 协议(protocol)实现发送通知。我通过了身份验证请求，我也在谷歌控制台中启用了 api。现在，当我发送请求时，我收到 Bad request 400 错误。响应不包含错误代码和错误消息以外的任何其他信息。甚至原因字段都显示“错误请求”。我正在用 FCM api docs 来实现它.

def fcm_test():
    FCM_URL = "https://fcm.googleapis.com/v1/projects/MY_PROJECT_NAME/messages:send"
    my_token = "device-token"

    payload = {
        "massage": {
            "token": my_token,
            "notification": {
                "body": "body",
                "title": "title"
            }
        }
    }

    payload = json.dumps(payload)
    headers = {
        "Authorization": "Bearer {auth_token}".format(auth_token=_get_authentication_token()),
        "Content-Type": "application/json; UTF-8",
    }
    try:
        request = moves.urllib.request.Request(FCM_URL, payload.encode('utf-8'), headers)
        response = moves.urllib.request.urlopen(request, timeout=10)
    except Exception as e:
        pass
    return

Answer 1

您的有效载荷 key 中有一个拼写错误，您可以用“message”而不是“massage”再试一次吗？
