Sending custom header with every request in webview

[sudheeshde]

Hi, consider this as a question, I succeeded to pass my custom header that contains a token for accessing the webpage into advancedwebview. It initiall yloads the page, but when using POST with another url in the webview, my header (token) actually didn't passed to server. Why is that? Is my code is broken? I also referred issue #27. But couldn't catch the idea. Please help me. I'm attaching my code here.

`public class TableViewTest extends AppCompatActivity implements AdvancedWebView.Listener {

    SharedPreferences pref;
    boolean preventCaching = true;

    private static final String URL = "my-url";
    private AdvancedWebView mWebView;

    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_table_view_test);

        pref = getSharedPreferences("LoginActivity", Context.MODE_PRIVATE);
        final String acToken = pref.getString("token", "DEFAULT");

       //used this method to add headers with every request, not working
        Map<String, String> headers = new HashMap<String, String>();
        headers.put("Authorization", "Bearer " + acToken);
        //mWebView.loadUrl(your url, headers);

        //webView = (WebView) findViewById(R.id.webView1Id);

        mWebView = (AdvancedWebView) findViewById(R.id.webview);
        mWebView.setListener(this, this);
        mWebView.setGeolocationEnabled(false);
        mWebView.setMixedContentAllowed(true);
        mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

        mWebView.setWebViewClient(new WebViewClient() {

            @Override

Don't worry, that problem is not your fault. But I'm afraid this also means there is no easy solution. Sorry!

It's explained in the Javadoc of the method that you're calling:

https://github.com/delight-im/Android-AdvancedWebView/blob/ab994097de27c1aa3b85ffc0b220c8fd83a446fd/Source/library/src/main/java/im/delight/android/webview/AdvancedWebView.java#L315

Unfortunately, there's no simple way to fix this, technically.

Okay, thank you for the reply.

[thorkous]

@sudheeshde can you post the code to catch the headers?

[giacomomasseron]

Same issue here, anyone solved?
