当我在Flask应用中处理登录提交时,发现CSS文件无法正确加载,显示404错误。经过仔细分析,我发现问题出在路由处理上。Flask默认会根据当前路由构建静态文件的路径,导致文件无法正确加载。为解决此问题,我手动构建了静态文件的路径,确保CSS文件始终从正确的根目录加载。

步骤解释:

  • 检查Flask配置:确保 static_folder 正确设置为 static,默认路径下即可。

  • 模板中手动构建路径:在模板中使用 url_for('static', filename='style.css'),确保路径正确。

  • 验证结果:在提交表单时,检查浏览器的开发工具,确保CSS文件加载正确路径。

  • 通过以上步骤,问题得以解决,CSS文件在任何路由下都能正确加载。
