By integrating our web system with Asana,
However, since early December, files attached to Asana have garbled filenames.
We use Java source distributed on GitHub for file attachment processing,
/**
* Upload a file and attach it to a task
*
* @param task Globally unique identifier for the task.
* @param fileContent Content of the file to be uploaded
* @param fileName Name of the file to be uploaded
* @param fileType MIME type of the file to be uploaded
* @return Request object
*/
public ItemRequest<Attachment> createOnTask(String task, InputStream fileContent, String fileName, String fileType) {
MultipartContent.Part part = new MultipartContent.Part()
.setContent(new InputStreamContent(fileType, fileContent))
.setHeaders(new HttpHeaders().set(
"Content-Disposition",
String.format("form-data; name=\"file\"; filename=\"%s\"", fileName) // TODO: escape fileName?
));
MultipartContent content = new MultipartContent()
.setMediaType(new HttpMediaType("multipart/form-data").setParameter("boundary", UUID.randomUUID().toString()))
.addPart(part);
I have confirmed that I am passing the correct string to fileName,
Our server processing has not changed before and after the phenomenon.
If you are experiencing the same situation,
Hi @TT-TMC , I just tried the same in our application and I confirm that filename is garbage after upload.
But, I have no idea if it was ok before, I don’t remember if we tested with complex utf-8 filenames.
But, that’s something I need to look on our side. Maybe we should add a utf-8 encoding headers somewhere I suppose.

Hi @Frederic_Malenfant ,When specifying a file name with Content-Disposition,
public ItemRequest<Attachment> createOnTask(String task, InputStream fileContent, String fileName, String fileType) {
String encFileName = fileName;
try {
encFileName = URLEncoder.encode(fileName, "UTF-8").replace("+", "%20");
} catch (UnsupportedEncodingException e1) {
e1.printStackTrace();
}
MultipartContent.Part part = new MultipartContent.Part()
.setContent(new InputStreamContent(fileType, fileContent))
.setHeaders(new HttpHeaders().set(
"Content-Disposition",
String.format("form-data; name=\"file\"; filename*=UTF-8''%s", encFileName)
// String.format("form-data; name=\"file\"; filename=\"%s\"", fileName) // TODO: escape fileName?
));

Same behaviour on me using the python-asana library (version=3.0.0).
Giving the param file_name some greek characters, the filename of the attachment file uploaded to Asana has wrong encoding.
Request:
client.attachments.create_attachment_for_task(
task_id=data['task_id'],
file_content=attachment,
file_name='τεστ συνημμένο',
file_content_type=attachment.content_type,
opt_pretty=True
)
Asana attachment filename stored:
ÏεÏÏ ÏÏ
νημμÎνο
Note that posting the same request using Postman, the attachment filename is stored with the correct encoding in the Asana task.
