I am trying to extract some info from a website which requires login to access said page. I created a webview to allow to user to log in first.

The question is, how to use the authorization info from that webview in other HTTP requests?

You can extract the cookies from the page and use them in later requests.

@Override
public void onPageFinished(WebView view, String url){
    String cookies = CookieManager.getInstance().getCookie(url);
    Log.d(TAG, "All the cookies in a string:" + cookies);
}

  • depends what you want to do with it. Are you trying to make http calls? or use it in another webview? or.... – Tomer Shemesh May 17 '16 at 18:33
  • How in that cookies you will know if the login process was successful? – hcarrasko May 17 '16 at 18:42
  • Prefereably http calls. – David Banker May 17 '16 at 18:43
  • @Hector well if it goes to a specific url when it logs in or errors you could check that. Most pages have that. Also some pages dont give you a valid cookie until the login is successful. It all depends on the specific website. – Tomer Shemesh May 17 '16 at 18:45
  • Let's assume login is successful, how do I use the cookies in a http request then? – David Banker May 17 '16 at 18:47
  • @DavidBanker When making an http call there will be ways to add headers. just add the header with key Cookie and the value cookies string we have just gotten – Tomer Shemesh May 17 '16 at 18:48
  • @TomerShemesh ah ok, then I should to create a cookie in the web app (ie. called "logsOK") to set if the logs in was successful, then in Android ask if this cookie exist? – hcarrasko May 17 '16 at 18:50
  • i think your getting mixed up. you shouldnt be creating any cookies. The website you are going to in the webview will create a cookie. Every website is different in what the cookie is called. you can use the chrome debug menu to view all the cookies and see whats created when you login. – Tomer Shemesh May 17 '16 at 18:52
