Autofill a form of another website and send it

问题

I searched the web and found nothing.

On the website, there is a Input box for a E-Mail address. I would like to fill this field with an e-mail address and the send the form. Then i will get the whole source code from the website.

I don't wanna give this to the URL like "?myvar=test&myvar2=test2". I searched for examples for CURL, but found nothing.

I only want fill the form, send it, and get the source code. Or is there an addon for firefox or a free program?

You will need to look at the form action attribute. This should point you to the script the form is posted to. When you have that information you can send a POST request to that url using curl or when in php,

$postdata = http_build_query(
    array(
        'email' => 'youremailaddress'
    )
); 
$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context  = stream_context_create($opts);

$result = file_get_contents('http://example.com/submit.php', false, $context);

You can do this, but not the way you expect. To POST a form, you need to first fetch the source code for it (with Curl, or whatever your preference). For each input on the form, you store the name and give it a value. Then you need to send those values with their respective names to the action url of the form, using the method and enctype specified on the form.
