Convert CURL to javascript fetch

How can I convert the following CURL command to javascript fetch?

curl --request GET -L -c --url https://tableau.example.com/trusted/DjabukX7T3u_bTUT0z7NdQ==:rQS3WF-ol-5snlDTOYlQ7pS2/t/site/views/workbook_name/view_name

I used the above command on my server is working.

Then I throw this command to many online CURL to javascript fetch converters, and they all return only like this:

fetch('https://tableau.example.com/trusted/DjabukX7T3u_bTUT0z7NdQ==:rQS3WF-ol-5snlDTOYlQ7pS2/t/site/views/workbook_name/view_name');

The above fetch code is not working for me. and it returns Uncaught (in promise) TypeError: Failed to fetch.

I think the -c -L flag in CURL has the meaning for fetching:

https://curl.se/docs/manpage.html#-c

https://curl.se/docs/manpage.html#-L

What is the precise corresponding javascript fetch code for this CURL command?

thanks for the help from all of you.

Answer

Most of the flags you are using for cURL are default behaviour for fetch.

Since you are making a cross-origin request you need to set the credentials flag to include for cookies to be enabled.

Note that this will require the server to support a CORS preflight.
