Android webview post 无法使用 extraheader

Question

我正在为客户开发 android 应用程序，我有一个加载外部链接的 webview，一些页面有一个带有 post 操作的表单，我使用 loadUrl（带覆盖）来添加extraHeaders（设备类型和访问令牌），但随着提交 header 丢失，我收到 401 错误。注意：我不能对客户端站点进行大修改，我必须从 android 应用程序端找到解决方案。

@SuppressLint("JavascriptInterface")
public void registerWebView() {
    Log.i("ACC TOKEN", DataSave.getAccessToken());
    mWebView = (AdvancedWebView) findViewById(R.id.mbrowser);
    mWebView.addHttpHeader(Utils.HEADER_AUTHORIZATION_NAME, "Bearer " + DataSave.getAccessToken());
    mWebView.addHttpHeader(Utils.HEADER_DEVICE_NAME, Utils.HEADER_DEVICE_VALUE);
    mWebView.addJavascriptInterface(new WebAppInterface(this), "Android");
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        WebView.setWebContentsDebuggingEnabled(true);
    }

    Log.i("WV FILE", AdvancedWebView.isFileUploadAvailable() + "");

    final GestureDetector gestureDetector = new GestureDetector(mContext, new GestureListener());
    mWebView.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            hideShareMenu();
            return gestureDetector.onTouchEvent(event);
        }

    });



    mWebView.setWebViewClient(new WebViewClient() {
        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            super.onReceivedError(view, errorCode, description, failingUrl);
            Log.i("WebView", "Got error !! " + errorCode);
        }

        public boolean shouldOverrideUrlLoading(WebView view, String urlT) {
            Log.i("WebView", "Loading " + urlT);
            if (urlT.contains(Utils.URL_ROOT)) {
                view.stopLoading();
                view.loadUrl(urlT, getExtraHeaders());
                return true;
            }else{
                view.stopLoading();
                Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(urlT));
                startActivity(browserIntent);
                return false;
            }
        }

        public void onPageFinished(WebView view, String url) {
            handleNavigationUI(url);
        }

    });



    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);
    webSettings.setLoadWithOverviewMode(true);
    webSettings.setUseWideViewPort(true);

    mPublicationIcon = (ImageView)findViewById(R.id.publication);

    mSearchActionBar = (RelativeLayout)findViewById(R.id.layout_find);
    mSearchActionBarHeight = Utils.dpToPx(mContext, 40);
    mSearchInput = (cEditText)findViewById(R.id.search_input);

    mPublicationIcon.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mWebView.loadUrl(Utils.URL_ROOT + Utils.URL_PUBLICATION);
            toggleSearchbar(false, "");
            togglePublicationIcon(false);
        }
    });

}
