Signed url with & causing problems when performing curl request

Question

I'm creating resumable upload signed urls in google cloud and passing the link to an external API for performing some process. On examining the callbacks from the API, I can see the url actually being split into different parameters because of the & present in the google signed url.

callback": "https://storage.googleapis.com/bucket/file-name?x-goog-"x-goog-date": "20220303T233221Z",
"x-goog-expires": "3600",
"callback_method": "put",
"x-goog-algorithm": "GOOG4-RSA-SHA256",
"x-goog-credential": "****",
"x-goog-signedheaders": "host"

The signed url looks like

https://storage.googleapis.com/bucket/file-name?x-goog-signature=4398348934893498fjksdfjksdjk&x-goog-algorithm=GOOG4-RSA-SHA256&x-goog-credential=bucket40project.iam.gserviceaccount.com%2F2003%2Fus-west1%2Fstorage%2Fgoog4_request&x-goog-date=202201Z&x-goog-expires=3600&x-goog-signedheaders=host

and the curl request to the API looks like

curl --request POST
-url 'website.com?callback=<the above url>"
--header 
--data

Any input would be really appreciated. I tried including an \ before the & or enclosing it within quotes, but nothing seems to work.

Using `urllib.parse.quote(url)` in python did the trick for me. — Tony Stark, Mar 07 '22 at 10:31

Based on this answer.

You need to url-encode the previous url

curl --request POST \
    --data-urlencode "callback=<the above url>" \
    website.com

This doesn't work for me unfortunately. – Tony Stark Mar 04 '22 at 12:49
