如何将.csv扩展名添加到Google App Engine中的文件下载中？

我在python中使用csv模块来从Google App Engine中的一个数据存储表中创建一个下载。下载工作正常，但您必须手动添加扩展名，以便您可以在Excel中打开它。我无法弄清楚如何修改响应，以便文件下载具有.csv扩展名。我可以让它像这样，但是这个网络应用程序是为了广泛的受众，所以我想让它尽可能容易让他们使用。如何将.csv扩展名添加到Google App Engine中的文件下载中？

相应的语法是：self.response.headers [ '内容处置'] =“附件;文件名= measurements.csv” –
