Question

我面临与谷歌应用引擎应用程序相同的问题。它适用于SDK（localhost），上传到appengine时无法正常工作。部署成功。我被困在这!!!任何帮助表示赞赏。

以下跟踪日志：

Answer 1

您的问题是您尝试加载的模板位于静态指令html中。

不需要将模板部署为静态资源 - 实际上您可能不应该这样做。

部署静态资源时，应用程序通常无法读取这些资源。最近添加了app.yaml指令，以便您阅读这些资源。

除非您希望静态提供html文件，否则只需删除/html静态指令，或将模板移到其他位置。

或添加指令。 application_readable到/html静态处理程序

请参阅静态处理程序的文档https://developers.google.com/appengine/docs/python/config/appconfig#Static_Directory_Handlers

就我个人而言，我建议不要静态地提供jinja模板以及使用它们进行渲染。

为什么这在开发环境中有效 - 开发环境不使用不同的存储机制来提供静态和应用程序可读资源。

Answer 2

您无法将模板存储在静态目录中。

只需从app.yaml中删除/html处理程序，如下所示：

application: cloud-chess
version: 2
runtime: python27
api_version: 1
threadsafe: yes

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

- url: /images
  static_dir: files/images/

- url: /scripts
  static_dir: files/scripts/

- url: .*
  script: chessboard.app

libraries:
- name: webapp2
  version: "2.5.2"
- name: jinja2
  version: latest

Appengine应用程序在部署时无法正常工作 - TemplateNotFound。它适用于localhost
