Question

我以为我能用思考和谷歌来解决这个问题，但我不是......

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

我在我的管理Web应用程序中使用它来创建任务并将.pdf文件附加到它们。

asana API docs指定

请求和响应仅支持UTF-8字符编码。

只要我在我附加的文件名中没有德语变音符号（在本例中为ö），一切正常。

这就是我的工作：我从mysql数据库（utf-8中的所有内容）中获取文件URL，并将其作为attach_to_task()函数的参数。

这是一个例子：

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

asana API python包装器的POST方法然后抛出'Received non 2xx or 404 status code on call'并且不上传文件。

但是，如果我手动将文件名中包含'ö'的文件上传到asana，然后使用python API包装器获取有关任务附件的信息，我会

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

在someone else's post中它说

UTF-8中的'p''是'\ xc3 \ xb6'。

但我真的不明白我试图上传的\xf6与他们回馈的\xf6之间有什么区别。但是，问题必须存在于包含变音符号的文件名中，因为对于无变音文件，它可以正常工作。

有人可以暗示我做错了吗？谢谢。

这是响应标题：

在详细（调试）模式下，我也得到了这个：

curl -v没有问题，并说出以下内容：

什么是Asana API unicode（utf-8）问题（文件附件）？
