【问题标题】:Getting Mime Type Error when loading Django CSS加载 Django CSS 时出现 Mime 类型错误
【发布时间】:2020-11-20 21:11:19
【问题描述】:

今天我的 Django 项目 CSS 文件出现问题。当我尝试访问我的页面时,我的 CSS 文件没有加载。起初,我以为问题只出在 Django 管理员身上,所以我问了this question,然而,我认为这个问题值得单独提问。

我的页面正常加载,只是没有 CSS 样式,也没有出现错误。但是,在 chrome 控制台中,我发现了这个错误:

Refused to apply style from 'https://[mywebsite].com/static/pathToMyCssFile/file.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

我不明白"its MIME type ('text/html') is not a supported stylesheet MIME type" 是什么意思?它是将我的 CSS 代码检测为 HTML 还是相反?

我也试过this解决方案。

编辑:我的管理 CSS 文件返回 404

Admin Base.CSS


谢谢!

【问题讨论】:

  • 尝试打开file.css。如果是django 404错误页面,给出这个页面的截图
  • @Talha Quddoos 由于 GAEfan 的回答,当我打开我的应用程序静态文件时不再出现错误。但是,我的管理页面 css 文件有 404 错误

标签: python css django


【解决方案1】:

应该是text/css mimetype,比如:<link rel="stylesheet" type="text/css" href="mystyle.css">

【讨论】:

  • 谢谢!我在我的模板html中忘记了这一点。现在我的页面似乎工作了。但是,我的管理页面仍然无法正常工作。
  • 我应该删除这个问题,因为它现在有效吗?管理员仍然无法工作,但这是我的另一个问题
  • 没有。您接受此答案,然后提出新问题
【解决方案2】:

在我在 AWS elastic beanstalk 上托管的 Django 应用程序上,我只需在我的 CSS 链接中添加 text/css 即可解决所有问题
