推荐答案

您无能为力.

您正在向服务器发送请求.此特定请求失败，因为服务器将请求发送到代理，并收到超时错误.您的服务器将状态报告回给您504.

You are sending a request to a server. This particular request fails, because the server sends a request to a proxy, and gets a timeout error. Your server reports this back to you as status 504.

修复它的唯一方法是修复代理(使其及时响应)，或者更改服务器以不依赖该代理.两者都在您的区域之外.

The only way to fix it is to fix the proxy (make it respond in a timely manner), or to change the server to not rely on that proxy. Both are outside your area.

您无法防止此类错误.您可以做的是找出发生此类问题时应该获得的用户体验，并加以实施.顺便提一句.如果您收到504错误，那么您也应该期待超时错误.假设您以60秒的超时向服务器发出请求，而服务器以60秒的超时向代理发出请求.因为两个超时都相同，所以有时您的服务器将收到代理超时并将其发送给您(状态504)，但是有时您对服务器的请求将在此之前超时，并且您会收到超时错误.

You cannot prevent such errors. What you can do is find out what user experience there should be when such a problem happens, and implement it. BTW. If you get 504 errors, then you should also expect timeout errors. Say you make a request to your server with 60 second timeout, and your server makes a request to the proxy with 60 second timeout. Because both timeouts are the same, sometimes your server will receive the proxy timeout and send it to you (status 504), but sometimes your request to the server will time out just before that, and you get a timeout error.
