获取名称和使用python扩展上传的文件（谷歌应用程序引擎） [英] Getting the name & extension of an uploaded file using python (google app engine)

问题描述

我正在使用表单将文件上传到Google应用引擎并将其存储在数据存储中。 l还希望存储原始文件名和扩展名以用于演示目的。

是否有从检索服务器端检索此数据的方法，或只能收集客户端并作为单独的字段发送（例如 http://www.tinyurl.com/5jybfq ）？

非常感谢。

对于那些遵循以下答案的解决方案： >

  this_file = self.request.params [file_upload_form_field_name]。filename 
 
（this_file_name （this_file_extension）= os.path.splitext（this_file）
 
 self.response.out.write（文件名：+ this_file_name +< br>）
 
 self.response.out.write（File extension：+ this_file_extension +< br>）
  

解决方案

请阅读

  self.request.params [<包含文件的表单元素名称> ] .filename 
  

I am using a form to upload files to the google app engine and store them in the datastore. l would also like to store the original file name and extension for presentation purposes.

Is there a way of retrieving this data from the post sever side or can it only be gathered client side and sent as separate fields (e.g. http://www.tinyurl.com/5jybfq)?

Many thanks.

For those that follow the solution dased on the answer below:

this_file = self.request.params["file_upload_form_field_name"].filename 

(this_file_name, this_file_extension) = os.path.splitext(this_file) 

self.response.out.write("File name: " + this_file_name + "<br>") 

self.response.out.write("File extension: " + this_file_extension + "<br>") 

解决方案

Does the snippet from this email work?

 self.request.params[<form element name with file>].filename
