用于PNG图像的chrome中的MIME类型警告 [英] MIME type warning in chrome for png images

问题描述

 资源解释为图像，但用MIME类型application / octet-stream传输。 
  

以前见过这个吗？

解决方案

使用ASP.NET开发服务器运行ASP.NET WebForms应用程序时遇到此问题。

我怀疑类似的情况也会发生，如果您使用IIS Express作为您的服务器（VS 2010 SP1）。

我的问题在本地通过编辑项目设置（在Web下）并从ASP.NET开发服务器更改为本地计算机上的IIS。我可以看到，PNG已经被正确定义为图像MIME类型，实际上，当我点击我的本地IIS服务器时，它将以正确的类型提供文件。

Just ran my site in chrome and suprisingly it comes up with this warning for each of my .png images:

Resource interpreted as image but transferred with MIME type application/octet-stream.

Anyone seen this before?

Regards

解决方案

I encountered this while running an ASP.NET WebForms app using the ASP.NET Development Server.

I suspect something similar will happen if you use IIS Express as your server as well (VS 2010 SP1).

I 'resolved' my problem locally by editing the project settings (under Web) and changed from the ASP.NET Development Server to IIS on my local machine. I can see that PNG was already defined correctly as an image MIME type and indeed when I hit my local IIS server it's serving up the file with the correct type.
