问题描述

我有以下日志

这是我的观点

# views.py
def approve(request, pk):
    logger.info("meeting_approve:")
    try:
        logger.info("approve: query company api")
        r = requests.get(
            f"{foo}/bar",
            timeout=5,
        )
    except Timeout:
        messages.add_message(
            request, messages.WARNING, "Cannot connect to company api."
        )
        logger.warn(f"meeting_approve: Cannot connect to company api")
        return JsonResponse({"error": "Cannot connect to company api"}, status=500)
    logger.info(f"meeting_approve: check security {pk}")
    meeting = Meeting.objects.get(id=pk)
    logger.info(f"meeting_approve: check if blocked {meeting.company}")

为什么我的 JsonResponse 超时？

解决方案

问题似乎是任何 5xx 状态都会使服务器超时。这可能是因为 api 试图通过电子邮件向管理员发送堆栈跟踪，而电子邮件未在服务器上配置。

解决方法是不使用 5xx 状态。

return JsonResponse({"error": "Cannot connect to company api"}, status=404)
