I'm trying to upload an image on Google cloud console with javascript, but it's not working at all.
I have tried with the multiple post URL's https://storage.googleapis.com/upload/storage/v1/b/${bucketName}/o/ https://storage.googleapis.com/upload/storage/v1/b/${bucketName}/o?uploadType=media&name=${filename}
but none of them works, it always says 404 not found.
I want to upload the image on google cloud console with help of Javascript or jQuery
A POST to the second URL pattern you listed, https://storage.googleapis.com/upload/storage/v1/b/BUCKET_NAME/o?uploadType=media&name=OBJECT_NAME, is correct.
There are several alternatives you could try, for example a PUT to the pattern https://storage.googleapis.com/BUCKET_NAME/OBJECT_NAME.
Getting a 404 is unexpected and somewhat hard to diagnose without the exact URL. The most obvious cause would be that a bucket of that name doesn't exist. Check for typos? The second most likely reason is that you are accidentally doing a PUT or a GET instead of a POST.
Try making the same call with cURL, wget, or similar to see if you can reproduce the issue with another tool.
