【问题描述】：

这是我当前的 app.yaml：

runtime: nodejs10
service: default

instance_class: F1
automatic_scaling:
  min_instances: 0
  max_instances: 2

handlers:

  # Serve extension from where they were requested
- url: /(.*\.(css|ico|js|png|jpg|gif|mp4|txt|xml|json))$
  static_files: dist/apps/my-app/browser/\1
  upload: dist/apps/my-app/browser/.*\.(css|ico|js|png|jpg|gif|mp4|txt|xml|json)$
  secure: always
  expiration: "365d"

  # Handle blog SEO routes
- url: /blog
  static_files: dist/apps/my-app/browser/blog/index.html
  upload: dist/apps/my-app/browser/blog/index.html
  secure: always
  expiration: "0s"

- url: /blog/introducing-my-app
  static_files: dist/apps/my-app/browser/blog/introducing-my-app/index.html
  upload: dist/apps/my-app/browser/blog/introducing-my-app/index.html
  secure: always
  expiration: "0s"

- url: /blog/added-international-support
  static_files: dist/apps/my-app/browser/blog/added-international-support/index.html
  upload: dist/apps/my-app/browser/blog/added-international-support/index.html
  secure: always
  expiration: "0s"

- url: /blog/new-blog-entry
  static_files: dist/apps/my-app/browser/blog/new-blog-entry/index.html
  upload: dist/apps/my-app/browser/blog/new-blog-entry/index.html
  secure: always
  expiration: "0s"

  # Handle default index.html
- url: /(.*)
  static_files: dist/apps/my-app/browser/index.html
  upload: dist/apps/my-app/browser/index.html
  secure: always
  expiration: "0s"

如何将“处理博客 SEO 路由”下的规则合并为一个规则？使用每个博客条目更新 app.yaml 是不可扩展的。

这个结构是从一个 Angular Universal Prerender 项目生成的。

我尝试了几种组合都没有运气：

- url: /blog/(.*)
  static_files: dist/apps/my-app/browser/blog/\1/index.html
  upload: dist/apps/my-app/browser/blog/\1/index.html
  secure: always
  expiration: "0s"

【解决方案1】：

我认为您的最后一次尝试与实际解决方案非常接近。请简单地调整upload 值：

- url: /blog/(.*)
  static_files: dist/apps/my-app/browser/\1/index.html
  upload: dist/apps/my-app/browser/(.*)/index.html
  secure: always
  expiration: "0s"

正如您在 Google Cloud documentation 中看到的那样，在描述 upload 键时，您需要在其定义中提供正则表达式占位符而不是反向引用。

请考虑在 SO 中查看类似的问题，例如 this one 或 this other。
