在 webview 上找不到文件异常 - 当文件实际存在时

Question

我正在尝试在 web 视图中加载网页，但出现以下异常：

java.io.FileNotFoundException: https://fonts.googleapis.com/css?family=Roboto:400,300,500,700,900,700italic

但令我惊讶的是，如果我点击链接：

我实际上可以在我的浏览器中加载它。许多其他文件也会发生这种情况，通常可以从浏览器访问这些文件。我在这里想念什么？

下面是我的自定义实现：

WebViewClient webViewClient = new WebViewClient() {

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


            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                if (webView.getProgress() == 100) {
                    stopAnim();
                }
            }


            @Override
            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
                NoNetworkDialog.showNetworkDialog(getActivity());

            }

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                if (!CheckConnection.isNetworkConnected(getActivity())) {
                    NoNetworkDialog.showNetworkDialog(getActivity());
                    return false;
                } else {
                    view.loadUrl(url);
                    return true;
                }

            }

            @Override
            public WebResourceResponse shouldInterceptRequest(WebView view, String url1) {

                //  if (!CheckConnection.isNetworkConnected(getActivity())) {
                //    NoNetworkDialog.showNetworkDialog(getActivity());
                //  } else {
                try {
                    URL url = new URL(url1);

                    HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();


                    CookieManager cookieManager = CookieManager.getInstance();
                    String cookie = cookieManager.getCookie(url.getHost());


                    urlConnection.setDoOutput(true);
                    urlConnection.setRequestProperty("Cookie", cookie);
                    urlConnection.setRequestProperty("***_USER_AGENT", "***_app");
                    urlConnection.setRequestMethod("GET");

                    InputStream in = new BufferedInputStream(urlConnection.getInputStream());

                    return new WebResourceResponse(urlConnection.getContentType(), "UTF-8", in);

                } catch (Exception e) {
                    e.printStackTrace();

                    return null;
                }
                //  }
                //  return null;
            }
        };

删除setDoOutput() 看看是否有效。您没有发出 POST 请求，也不需要它。
