Question

我上傳谷歌App Engine的應用程序，它是在URL developers.google.com/appengine/docs/python/memcache/usingmemcache#Memcache

當我運行在谷歌應用程序App Engine的啓動，運行，但該網站顯示： （第一個錯誤是有我們沒有的Python「PIL」模塊，但我不使用圖像能否請你建議是什麼原因造成的錯誤

Answer 1

確保？您在上傳應用程序的路徑中包含以下文件：

1. index.yaml（自動生成;此時您不需要添加或更改任何內容）。

2. favicon.ico（正確的格式;如果我沒有記錯，應該是16x16或32x32像素）。

3. main.py（映射在你的網站的所有路徑;下面的例子給出）：

   from webapp2 import WSGIApplication 
   from Server import MainRequestHandler 
   from Server import SomeRequestHandler 
   from Server import OtherRequestHandler 
   
   app = WSGIApplication([ 
       ('/'    ,MainRequestHandler), 
       ('/abc'   ,SomeRequestHandler), 
       ('/def'   ,SomeRequestHandler), 
       ('/xyz'   ,OtherRequestHandler), 
   ]) 
   

4. 的app.yaml（包含以下內容;使用<...>在您需要設置的值）：

   application: <the app-id you chose when use signed in for GAE> 
   version: 1 
   runtime: python27 
   api_version: 1 
   threadsafe: yes 
   
   handlers: 
   - url: /favicon\.ico 
       static_files: favicon.ico 
       upload: favicon\.ico 
   
   - url: .* 
       script: main.app 
   
   libraries: 
   - name: webapp2 
       version: "2.5.1" // you might need to change this as well 
   

Note：

如果您希望避免處理'favicon.ico'請求，那麼您必須刪除文件'app.yaml'中的引用。

補充：

您將需要實現所有在 'main.py' 進口請求處理程序。

在上面的例子中，「main.py」希望能夠找到它們命名爲「服務器」一個Python模塊中。

每個請求處理程序必須繼承class RequestHandler，從webapp2進口。

補充＃2：

爲了解決「PIL」的問題（也有類似的問題，如果記錯），只需安裝它。

從Windows命令行中輸入：PIP安裝PIL。
