如何在WebView中更新请求标头 [英] How to update request header in WebView

我正在尝试从android Webview访问URL.在加载我通过chrome检查的URL时，一个标头值为null(请参见下图).

I'm trying to access a URL from android WebView. While loading the URL i inspected through chrome that one header value is null (See the following image).

推荐答案

    webView = (WebView) findViewById(R.id.webView);
    progressBar = (ProgressBar) findViewById(R.id.progressBar);

    webView.getSettings().setJavaScriptEnabled(true);
    webView.setWebChromeClient(new WebChromeClient() {
        public void onProgressChanged(WebView view, int progress) {
            progressBar.setProgress(progress);
            if (progress == 100) {
                progressBar.setVisibility(View.GONE);
            }
        }
    });




    HashMap<String, String> headers=new HashMap<>();

    webView.loadUrl("https://stackoverflow.com",headers);
