Google App Engine无法显示图片和CSS

Question

我是GAE的新手，并尝试在其上部署我的php应用程序，但是当我在浏览器中打开main.php时，它不会显示任何CSS和图像。

我的目录结构是

我的 app.yaml

application: blogakash
version: 1
runtime: php
api_version: 1
threadsafe: yes

handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: .*
  script: main.php

- url: /install_ubuntu.php
  script: install_ubuntu.php

- url: /install_virtualbox.php
  script: install_virtualbox.php

- url: /install_xampp.php
  script: install_xampp.php

- url: /tutorials.php
  script: tutorials.php


- url: /images
  static_dir: images

- url: /css
  static_dir: css

和我的记录

GAE无法上传我的CSS和图像。我无法理解日志说的内容。我还搜索了堆栈上类似的线程，尝试了大部分内容，但dint得到了任何输出。

我在安装或配置中遗漏了什么？

感谢。
