Curl - post form issue
I'm having an issue with curl post form, I dont' understand what I'm mising. I would like to send a post command login/password to a form, quite simple in the paper.
URL : http: // <myebsite> / login

Here the form source code :

Code:
<form action="/login_check" method="post">    

<input type="text" id="username" name="_username" value=""/>      

<input type="password" id="password" name="_password" />      

<button type="submit">Connexion</button></form>


When I submit the form from Firefox, I got the http header :

Code:
http: // <mywebsite> /login_check

So I wrote this command :

Code:
curl -v -d "_username=test&_password=test" -H "User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:64.0) Gecko/20100101 Firefox/64.0" -H "Content-type: application/x-www-form-urlencoded" http: // <mywebsite> /login > curl.html

Here the verbose log :

Code:

*   Trying <ip>... connected

In curl.html, I have the current form, without notification of the error or the succeed, depending the login I use. It's like it does nothing.

Is it because of the redirection ? or that the submit button doesn't have an id ?

Any help would be appreciated Smilie

Thank you
