Golang interface 504 error: how to solve it?

When writing web applications using Golang, we may encounter many types of errors. One of the common errors is the 504 gateway timeout error. This error means that our application timed out while processing the request, or it failed to receive a response from another server. If you are facing this problem, this article will provide you with some solutions.

1. Increase the timeout

If your Golang application times out, then you can try increasing the timeout so that more time is used to process requests. In Go, we can set the timeout by setting the Timeout property of http.Client. Here is a sample code:

client := &http.Client{
   Timeout: time.Second * 30,
}

In the above code, we set the timeout to 30 seconds. You can adjust this time based on your application needs.

2. Enable HTTP Keep-Alive

Enabling HTTP Keep-Alive can reduce the latency of HTTP requests and allow multiple requests to be transmitted through the same socket. This can be achieved by setting the Connection header. In Golang, we can use http.Transport to set the Connection header:

tr := &http.Transport{
    MaxIdleConns:    10,
    IdleConnTimeout: 30 * time.Second,
}

client := &http.Client{Transport: tr}

In the above code, we set the MaxIdleConns property to 10, which means we can use up to 10 connections in the idle state. The IdleConnTimeout property sets a time period during which an idle socket will be closed if no requests are made using it.

3. Bundle requests

If your application needs to handle a large number of data requests, you can try to break the data requests into multiple small requests to reduce processing time. This can also reduce load issues caused by too frequent requests.

4. Check the network connection

If your application cannot receive a response from another server, there may be a problem with the network connection. Check whether the network connection is normal and restart your network device if necessary.

5. Check the server log

If you cannot resolve this issue, please check the server log. The log files may provide more information about the problem. You may need to check for problems with your network equipment or firewall settings.

Summary

504 gateway timeout error is a common problem when writing web applications in Golang. This article provides some ways to solve this problem, including increasing the timeout, enabling HTTP Keep-Alive, packetizing requests, checking network connections, and viewing server logs. Please try these methods based on your application needs and get positive results.
