Delete Objects in Bucket with jQuery - autodesk-forge

Question

How do i selete an object in a bucket through a jQuery-Call. The following Code shows my example for uploading the file. The goal is to have the deleting in a similar way. Thanks
function uploadFile(node) {
$('#hiddenUploadField').click();
$('#hiddenUploadField').change(function () {
if (this.files.length == 0) return;
var file = this.files[0];
switch (node.type) {
case 'bucket':
var formData = new FormData();
formData.append('fileToUpload', file);
formData.append('bucketKey', node.id);
$.ajax({
url: '/api/forge/oss/objects',
data: formData,
processData: false,
contentType: false,
type: 'POST',
success: function (data) {
$('#appBuckets').jstree(true).refresh_node(node);
}
});
break;
}
});
}

You could expose the necessary part on the server side (just like it is done for the /api/forge/oss/objects endpoint which uploads a file to a given bucket) which then could be called from the client side in a similar way.
Server side:
router.delete('/buckets/:id', function (req, res) {
var tokenSession = new token(req.session)
var id = req.params.id
var buckets = new forgeSDK.BucketsApi();
buckets.deleteBucket(id, tokenSession.getOAuth(), tokenSession.getCredentials())
.then(function (data) {
res.json({ status: "success" })
})
.catch(function (error) {
res.status(error.statusCode).end(error.statusMessage);
})
})
Client side:
function deleteBucket(id) {
console.log("Delete bucket = " + id);
$.ajax({
url: '/dm/buckets/' + encodeURIComponent(id),
type: 'DELETE'
}).done(function (data) {
console.log(data);
if (data.status === 'success') {
$('#forgeFiles').jstree(true).refresh()
showProgress("Bucket deleted", "success")
}
}).fail(function(err) {
console.log('DELETE /dm/buckets/ call failed\n' + err.statusText);
});
}
Have a look at this sample which has both file upload and bucket deletion implemented: https://github.com/adamenagy/oss.manager-nodejs

Ah great, thank you. And how would you solve it on the server side with C# ? Rigth now the Upload on server-side looks like:
[HttpPost]
[Route("api/forge/oss/objects")]
public async Task<dynamic> UploadObject()
{
// basic input validation
HttpRequest req = HttpContext.Current.Request;
if (string.IsNullOrWhiteSpace(req.Params["bucketKey"]))
throw new System.Exception("BucketKey parameter was not provided.");
if (req.Files.Count != 1)
throw new System.Exception("Missing file to upload");
string bucketKey = req.Params["bucketKey"];
HttpPostedFile file = req.Files[0];
// save the file on the server
var fileSavePath = Path.Combine(HttpContext.Current.Server.MapPath("~/App_Data"),
file.FileName);
file.SaveAs(fileSavePath);
// get the bucket...
dynamic oauth = await OAuthController.GetInternalAsync();
ObjectsApi objects = new ObjectsApi();
objects.Configuration.AccessToken = oauth.access_token;
// upload the file/object, which will create a new object
dynamic uploadedObj;
using (StreamReader streamReader = new StreamReader(fileSavePath))
{
uploadedObj = await objects.UploadObjectAsync(bucketKey,file.FileName,
(int)streamReader.BaseStream.Length, streamReader.BaseStream,"application/octet-
stream");
}
// cleanup
File.Delete(fileSavePath);
return uploadedObj;
}
