无法摆脱丢失的manifest.json错误 [英] Can't get rid of missing manifest.json error

问题描述

我正在Visual Studio 2017中使用ReactJs前端构建一个ASP.NET Core应用.

I'm building an ASP.NET Core app with ReactJs front-end in Visual Studio 2017.

最近，我开始注意到控制台中丢失的manifest.json错误-参见下文.它似乎并没有影响我的应用程序，但我确实想摆脱此错误.

Recently, I started to notice the missing manifest.json error in the console -- see below. It doesn't seem to effect my app but I do want to get rid of this error.

如果我在Edge中查看我的应用，则看不到丢失的manifest.json错误，因此该错误似乎仅包含在Chrome中.

If I view my app in Edge, I don't see the missing manifest.json error so this error seems to be contained to Chrome only.

我将应用程序发布到Azure，然后再次在Chrome中出现相同的错误，但没有在Edge中出现.

I published the app to Azure and again, in Chrome, I'm getting the same error but not in Edge.

有什么办法可以解决吗?

Any idea how I can solve it?

推荐答案

很可能在项目中某个地方引用了manifest.json，而文件/资源​​本身不存在.

Most probably there is a reference to manifest.json somewhere in the project, while the file/resource itself does not exist.

检查是否有与rel=manifest类似的link标签

Check to see if you have any link tags with rel=manifest similar to

<link rel="manifest" href="/manifest.webmanifest">

在规范的媒体类型注册部分中指定了.webmanifest扩展名，但是浏览器通常支持带有其他适当扩展名的清单，例如.json.

The .webmanifest extension is specified in the Media type registration section of the specification, but browsers generally support manifests with other appropriate extensions like .json.

即

<link rel="manifest" href="/manifest.json">

并将其从代码中删除以停止错误.

and remove it from the code to stop the error.
