💡 MIME类型在Web开发中很重要，正确配置Content-Type头确保浏览器正确解析文件。
MIME（Multipurpose Internet Mail Extensions）类型是一种标准，用于表示文件的媒体类型和格式。服务器通过Content-Type头告诉浏览器如何处理返回的资源。格式为type/subtype，例如text/html。
常见MIME类型包括：text/html（HTML文件）、application/json（JSON数据）、image/png（PNG图片）、application/pdf（PDF文档）、text/css（CSS样式表）、application/javascript（JavaScript文件）。
在Web服务器（如Nginx、Apache）中配置MIME类型。Nginx使用types指令，Apache使用AddType指令。错误配置可能导致文件无法正确加载或安全隐患。
MIME类型配置错误会导致浏览器无法正确解析文件。例如CSS文件被当作text/plain时样式不会生效。使用X-Content-Type-Options: nosniff头可以防止MIME嗅探。
