Download an Issue Attachment
Use the REST API to download an attachment of a specific issue.
To solve this task, you basically need to obtain a full download URl of a specific issue attachment. To do so:
Get a list of available attachments with their attributes.
Get the attachment by its returned URL.
note
Please note that any reading operation with an attachment requires you to have a user account that is granted permission to read the target issue and its attachments.
To get the list of issue attachments, send a GET request to the following endpoint:
/api/issues/{issue_ID}/attachmentsTo form a download URL for an attachment, make sure you specify the url attribute in the fields request parameters. To make the identification of the target attachment easier, add also the name attribute at least.
For example:
curl -X GET
'https://example.youtrack.cloud/api/issues/2-6/attachments?fields=name,size,mimeType,extension,charset,url' /
-H 'Accept: application/json' /
-H 'Authorization: Bearer {TOKEN}'[
{
"charset": null,
"extension": "png",
"url": "/youtrack/api/files/7-2?sign=MTYxMzE2OTAwMDAwMHwxLTF8Ny0yfHdrRzJCYzA2cnZEclFLUzBLWEp6NXZGNE5kczA5eGVIVUUw%0D%0AbF9BVHZ3V3MNCg%0D%0A&updated=1569436739288",
"mimeType": "image/png",
"name": "orphan-modules.png",
"size": 208788,
"$type": "IssueAttachment"
},
{
"charset": null,
"extension": "png",
"url": "/youtrack/api/files/7-3?sign=MTYxMzE2OTAwMDAwMHwxLTF8Ny0zfFMxNW12bkFfNmhWZTFrWjhGa3lNZmF4Umt2MmFXWU1UWUFu%0D%0AUDJhalhITHMNCg%0D%0A&updated=1554209920719",
"mimeType": "image/png",
"name": "older-versions.png",
"size": 23812,
"$type": "IssueAttachment"
}
]Now all we need to do is to follow the link that we've received in the url attribute of the attachment and save the result as a file.
Make a request in the following format:
curl -X GET --output picture.png 'https://{HOST:PORT}{URL from previous request}' -H 'Cache-Control: no-cache'For example:
curl -X GET --output orphan-modules.png \
'https://example.youtrack.cloud/api/files/7-2?sign=MTYxMzE2OTAwMDAwMHwxLTF8Ny0yfHdrRzJCYzA2cnZEclFLUzBLWEp6NXZGNE5kczA5eGVIVUUw%0D%0AbF9BVHZ3V3MNCg%0D%0A&updated=1569436739288' \
-H 'Cache-Control: no-cache'Note that the Authorization header here is not required because the client is identified using the sign= request parameter.
