Express JS阻止GET/favicon.ico [英] Express js prevent GET /favicon.ico

问题描述

在每个请求中，即使是不包含html文件的REST API，我的服务器也正在接收对/favicon.ico的GET请求.为什么会发生这种情况，如何阻止该请求?

In every request, my server is receiving GET request to /favicon.ico, even when it's REST api that not include html file. Why is this happening and how can I prevent this request?

推荐答案

浏览器默认情况下将尝试从主机名的根请求/favicon.ico，以便在浏览器选项卡中显示图标.

Browsers will by default try to request /favicon.ico from the root of a hostname, in order to show an icon in the browser tab.

如果您想避免此请求返回404，则可以:

If you want to avoid this request returning a 404, you can either:

• 提供一个favicon.ico文件，该文件在您网站的根目录中可用.
• 使用诸如 serve-favicon 之类的模块将请求指向特定文件.
li>

• 捕获favicon.ico请求并发送204 No Content状态:

• Supply a favicon.ico file that is available at the root of your site.
• Use a module such as serve-favicon to point requests to a specific file.

• Catch the favicon.ico request and send a 204 No Content status:

app.get('/favicon.ico', (req, res) => res.status(204));
