What does '--user' mean with curl

Question

I\'m working with an API and I have to send a POST request. I know how to set a header (-H) and (-d) is the body, but what is \"--user\".

If I submit this with Postm

Answer 1

Specify the user name and password to use for server authentication. If you simply specify the user name, curl will prompt for a password.

If your curl request does not have any -- user, then server that requires authentication sends back a 401 response code and an associated WWW-Authenticate: header that lists all the authentication methods that the server supports.

< HTTP/1.1 401 
< WWW-Authenticate: Basic realm="oauth2/client"

Then you will know the server is using Basic authentication

You can add --basic to explicitly tell it is Basic authentication

Please refer to HTTP authentication for more information
