推荐答案

正在上传的文件的文件名可以通过查看包含该文件的变量的 filename 属性来确定文件。例如，假设您的表单有一个名为 content 的字段：

The filename of the file that is being uploaded can be determined by looking at the filename property of the variable that holds the file. For example, let's say that your form has a field named content:

<input type="file" name="content" />

在您的Handler中，您可以找到文件名称：

Inside your Handler, you could find the name of the file with:

filename = self.request.POST["content"].filename
