Hi,
How do I open a website in a browser, enter login data and get the resulting page content automatically?
I found this:
https://de.mathworks.com/matlabcentral/answers/246143-how-do-i-open-a-website-in-a-browser-enter-login-data-and-get-the-resulting-page-content-automatica
the author wrote:
I did this:
url = 'http://www.myurl.com';
options = {'Username', 'myUsername', 'Password', 'myPassword', 'Timeout', 10};
z = webwrite(url, options);
What I get in z is just the source code of the login page. Do I have to use the URL of the login page or can I use the URL I want to go to after login? How would I get that content, when I have to use the login URL? Do I have to do something with a cookie? Could it be that the website which I try to login do not support RESTful API? How can I find out?
I have same questions and did not find the answers. Who can help?

Hi! You can use webread and weboptions together. And you must point to the page that you want to download (HTML code or json text, for example).
message = webread('www.myurl.com', weboptions('Username', 'YourUsername', 'Password', 'YourPassword'))
