Parsing HTML with cURL POST

Question

I'm sending POST request to some link with valid username and password.

I use this command: curl -X POST -F '[email protected]' -F 'password=123' http://my.site.com/login

but it got Moved Temporarily. Redirecting to /

How can I redirect with cURL ?

HTTP/1.1 302 Moved Temporarily
Server: nginx

<p>Moved Temporarily. Redirecting to <a href="/">/</a></p>

Answer 1

curl's -L (--location) option follows a redirected URL:

curl -LX POST ...

But the caveat is that, this will follow redirections after login. If the login page redirects to another login page where you need to (re)submit the same POST request, then you need to use the --location-trusted option to make all the redirected URLs as trusted, otherwise curl will send the POST authentication info only to the initial URL. So if you trust the redirected URL, do:

curl -L --location-trusted -X POST ...
