Rails 中的 ActionController::RoutingError(没有路由匹配 [GET] “/favicon.ico") [英] ActionController::RoutingError (No route matches [GET] "/favicon.ico") in Rails

问题描述

我试过使用

<link href="/favicon.ico" rel="shortcut icon" /> 

还有这个

<link href="/assets/favicon.ico" rel="shortcut icon" />

但我仍然在日志文件中看到此错误

but I am still seeing this error in the log file

ActionController::RoutingError (No route matches [GET] "/favicon.ico"):

favicon.ico 在 public 文件夹中(我也把它放在 app/assets 文件夹中)

the favicon.ico is there in public folder (I have also put it in app/assets folder too)

如何修复这个错误?

推荐答案

您收到此错误是因为您的 public/ 中没有 favicon.ico> 应用程序目录.由于该文件在那里不存在，Rails 继续前进，在 config/routes.rb 中寻找与 /favicon.ico 匹配的路由.

You're getting this error because you don't have a favicon.ico in your public/ directory of your application. Because the file doesn't exist there, Rails moves on, looking for a route to match against /favicon.ico in the config/routes.rb.

您可以通过以下两种方式之一解决此问题

You can fix this in one of two ways

1. 手动将 favicon.ico 文件放在应用程序的 public/ 目录中.

2. 将 favicon.ico 放在 app/assets/images/ 中，然后更改您的 标签使用 image_path

1. Manually place the favicon.ico file in the public/ directory of your application.

2. Put the favicon.ico in app/assets/images/ and then change your <link ... tag to use image_path

<link href="<%= image_path("favicon.ico") %>" rel="shortcut icon" />

这会将 favicon.ico 放在 public/assets/favicon.ico 中，不 放在文档根目录中.

This will place the favicon.ico in public/assets/favicon.ico, not in the document root.

我建议坚持上面的#1.

至于为什么这个请求甚至出现在您的日志中，许多现代浏览器在域的根目录中查找 /favicon.ico 以用于书签，或选项卡或地址栏中的演示文稿.这就是为什么最好将 favicon.ico 保留在域的根目录中，以防浏览器决定(无论出于何种原因)忽略您的 <link rel="icon快捷方式" ... 标签.

As for why this request is even showing up in your logs, many modern browsers look in the root of the domain for /favicon.ico to use for bookmarking, or presentation in a tab or the address bar. This is why it's a good idea to keep the favicon.ico in the root of your domain, in case a browser decides (for whatever reason) to ignore your <link rel="icon shortcut" ... tag.
