css因为mime被阻止,CSS文件被阻止:MIME类型不匹配(X-Content-Type-Options:nosniff)...

我正在开发Angular 4应用,我想应用一些全局样式。在有关角度站点的教程之后,我在应用程序的根目录中创建了一个“

styles.css”文件,并在我的应用程序的index.html中引用了该样式表:

angular应用已成功编译:

$ ng serve

** NG Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200 **

[...]

webpack: Compiled successfully.

但是,当我在Chromium浏览器中访问http://

localhost:4200时,控制台显示错误消息

GET http://localhost:4200/styles.css

在Firefox浏览器中,该错误更为明显:

GET

http://localhost:4200/styles.css [HTTP/1.1 404 Not Found 15ms]

The resource from "http://localhost:4200/styles.css" was blocked due to MIME type mismatch (X-Content-Type-Options: nosniff).

这两个文件index.html和styles.css都位于我的角度应用程序的根目录中。我试图获得有关该问题的更多信息:

nosniff

Blocks a request if the requested type is

"style" and the MIME type is not "text/css", or

"script" and the MIME type is not a JavaScript MIME type.

但是我不明白为什么它使请求无效,因为我type="text/css"在引用样式表时已指定。
