webview android如何添加authorization header？

public class MyWebViewClient extends WebViewClient {
    private String authorizationHeader;

    public MyWebViewClient(String authorizationHeader) {
        this.authorizationHeader = authorizationHeader;
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        super.onPageStarted(view, url, favicon);
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
    }

    @Override
    public void onLoadResource(WebView view, String url) {
        super.onLoadResource(view, url);
    }

    @Override
    public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Map<String, String> headers = request.getRequestHeaders();
            headers.put("Authorization", authorizationHeader);
            request.setRequestHeaders(headers);
        }
        return super.shouldInterceptRequest(view, request);
    }
}

WebView webView = new WebView(context);
String authorizationHeader = "Bearer your_token_here";
webView.setWebViewClient(new MyWebViewClient(authorizationHeader));
