Using WebView setHttpAuthUsernamePassword?

Question

I\'m trying to do basic authentication to view a protected url. I want to access the protected url which looks like this:

http://api.test.com/userinfo/vid?=1         


        

Answer 1

In this example realm is By Invitation Only

AuthType Basic
AuthName "By Invitation Only"
AuthUserFile /usr/local/apache/passwd/passwords
Require user rbowen sungo

Answer 2

I never did get setHttpAuthUsernamePassword to work with phonegap's FileTransfer.download (since it doesn't use the webview), but I DID get this to work with phonegap. It's worth noting if any other phonegap people end up on this thread.

    Authenticator.setDefault(new Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(user, pass.toCharArray());
        }
    });

Answer 3

You may need something other than "" for the second parameter. Contact the developer of the Web site and find out what an appropriate realm should be. Or, use tools like curl to find out what the realm should be.

Answer 4

webview.setWebViewClient(new WebViewClient () {

    public void onReceivedHttpAuthRequest(WebView view,
            HttpAuthHandler handler, String host, String realm) {

        handler.proceed("login", "pass");
    }
});

Answer 5

This is so silly. I hacked something together that worked for me, I hope it'll work for you too.

public class AuthRequestDialogFragment extends DialogFragment
{
    @InjectView(R.id.dauth_userinput)
    public EditText userinput;

    @InjectView(R.id.dauth_passinput)
    public EditText passinput;

    @OnClick(R.id.dauth_login)
    public void login(View view) {
        ((Callback) getTargetFragment()).login(userinput.getText().toString(), passinput.getText().toString());
        this.dismiss();
    }

    @OnClick(R.id.dauth_cancel)
    public void cancel(View view) {
        ((Callback) getTargetFragment()).cancel();
        this.dismiss();
    }

    public static interface Callback
    {
        public void login(String username, String password);
        public void cancel();
    }

    @Override
    public void onStart() {
        super.onStart();
        WindowManager wm = (WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE);
        Display display = wm.getDefaultDisplay();
        int width = display.getWidth();
        int height = display.getHeight();

        getDialog().getWindow().setLayout(width*2/3, height/5*2);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        View view = inflater.inflate(R.layout.dialog_authrequest, container);
        ButterKnife.inject(this, view);
        getDialog().setTitle("Authorization required");
        return view;
    }
}

And

                android:layout_width="wrap_content"

        <EditText

            android:layout_alignBottom="@+id/dauth_passtext"
            android:layout_toRightOf="@id/dauth_passtext"
            android:layout_toEndOf="@id/dauth_passtext"
            android:layout_alignLeft="@id/dauth_userinput"
            android:layout_alignStart="@id/dauth_userinput"/>

    </RelativeLayout>

    <Button
        android:id="@+id/dauth_cancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Cancel"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_marginBottom="15dp"
        android:layout_marginRight="15dp"
        android:layout_marginEnd="15dp"/>


    <Button
        android:id="@+id/dauth_login"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Log In"
        android:layout_alignTop="@+id/dauth_cancel"
        android:layout_marginRight="15dp"
        android:layout_marginEnd="15dp"
        android:layout_toLeftOf="@+id/dauth_cancel"/>



</RelativeLayout>

And

public class WebViewFragment extends Fragment implements AuthRequestDialogFragment.Callback {

    @Override
    public void login(String username, String password) {
        Log.d(this.getClass().getName(), "Login");
        myWebViewClient.login(username, password);
    }

    @Override
    public void cancel() {
        Log.d(this.getClass().getName(), "Cancel");
        myWebViewClient.cancel();
    }

And the most important:

private class MyWebViewClient extends WebViewClient {
    private WebView myView;
    private HttpAuthHandler httpAuthHandler;
    private String host;
    private String realm;

    @Override
    public void onReceivedHttpAuthRequest(WebView view, HttpAuthHandler handler, String host, String realm) {
        AuthRequestDialogFragment authRequestDialogFragment = new AuthRequestDialogFragment();
        FragmentManager fragmentManager = ((getActivity()).getSupportFragmentManager());
        authRequestDialogFragment.setTargetFragment(WebViewFragment.this, 0);
        authRequestDialogFragment.show(fragmentManager, "dialog");
        this.httpAuthHandler = handler;
        this.myView = view;
        this.host = host;
        this.realm = realm;
    }

    public void login(String username, String password) {
        httpAuthHandler.proceed(username, password);
        myView = null;
        httpAuthHandler = null;
        host = null;
        realm = null;
    }

    public void cancel() {
        super.onReceivedHttpAuthRequest(myView, httpAuthHandler, host, realm);
        myView = null;
        httpAuthHandler = null;
        host = null;
        realm = null;
    }
}

Uses dependency:

compile 'com.jakewharton:butterknife:6.0.0'

Answer 6

Another option is to use a WebViewClient;

webview.setWebViewClient(new MyWebViewClient ());

private class MyWebViewClient extends WebViewClient {
@Override
public void onReceivedHttpAuthRequest(WebView view,
        HttpAuthHandler handler, String host, String realm) {

    handler.proceed("me@test.com", "mypassword");

}
}
