無法在Google App Engine中上傳文件

Question

我不知道爲什麼我無法上傳我的文件？當我點擊提交而不是重定向到默認頁面（即http://localhost:8082）時，它重定向到http://localhost:8082/sign。我沒有建立這樣的路徑，所以它返回鏈接斷開。這裏是我的html：

<form action="/sign" enctype="multipart/form-data" method="post"> 
       <div><label>Excel file submit:</label></div> 
       <div><input type="file" name="excel"/></div> 
       <div><input type="submit" value="Upload file"></div> 
      </form> 

我的app.yaml：

application: engineapp01 
version: 1 
runtime: python 
api_version: 1 

handlers: 
- url: /js 
    static_dir: js 
- url: /css 
    static_dir: css 
- url: .* 
    script: main.py 

main.py：

你爲什麼表單數據發送到一個不存在的頁面？

嘗試改變HTML到：

<form action="/" enctype="multipart/form-data" method="post"> 
... 

...因爲 「/」 是你的表單處理代碼所在。
