这里的Asana-API unicode（uft8）问题是什么（文件附件）？

Question

我以为我可以用思维和谷歌来解决这个问题，但我没有。。。在

有一个asana API python wrapper，我forked and extended，所以它处理文件上传。在

我在我的管理web应用程序中使用它来创建任务并向它们附加.pdf文件。在

asana API docs指定

Only the UTF-8 character encoding is supported for both requests and responses.

只要我在附加的文件名中没有德语元音变音（在本例中是廑），一切都会正常工作。在

我要做的是：从mysql数据库（所有内容都是utf-8）中获取一个文件URL，并将其作为attach_to_task()函数的参数。在

这就是一个例子：

u'/Users/Foo/directory/inv\xf6ice.pdf'

asanaapi python包装器的POST方法随后抛出一个'Received non 2xx or 404 status code on call'，并且不上载该文件。在

但是，如果我手动将文件名中包含“ö”的文件上载到asana，然后使用pythonapi包装器来获取关于任务附件的信息，那么

{u'id': 99347997, u'name': u'inv\xf6ice.pdf'}回来。在

在someone else's post里写着

'ö' in UTF-8 is '\xc3\xb6'.

但我真的不明白我试图上传的\xf6和他们回馈的\xf6之间有什么区别。但是，这个问题必须存在于包含元音变音的文件名中，因为对于没有元音变化的文件，它工作得非常好。在

有人能告诉我我做错了什么吗？谢谢您。在

这是响应标头：

在详细（调试）模式下，我还得到：

{u'errors': [{u'message': u'file: File is not an object'}]}
