Question

我有一个webview，我想要添加自定义标题，我希望这可以满足重定向并查看如何执行此操作，我偶然发现了最高投票答案here。

但是，此解决方案使用的是现已弃用的方法。我试图修改解决方案：

 public void webViewUrlConn() {
        new Thread(new Runnable() {

            @Override
            public void run() {

                try {
                    URL url = new URL("https://someUrl.com");

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


                    CookieManager cookieManager = CookieManager.getInstance();
                    String cookie = cookieManager.getCookie(url.getHost());
                    urlConnection.setDoOutput(true);
                    urlConnection.setRequestProperty("Cookie", cookie);
                    urlConnection.setRequestProperty("CRM_USER_AGENT", "crm_app");
                    urlConnection.setRequestMethod("POST");

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


                    data = new java.util.Scanner(in).useDelimiter("\\A").next();

                    System.out.println("Data:" + data);

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

                getActivity().runOnUiThread(new Runnable() {
                    public void run() {
                        wv.loadData(data, "text/html", "UTF-8");
                        pd.setVisibility(View.INVISIBLE);
                        wv.setVisibility(View.VISIBLE);

                    }
                });


            }
        }).start();
    }

这完美无瑕。但这不是我需要的。我想覆盖WebViewClient类以满足即使是在webview上点击的链接，我想出了以下内容：

 WebViewClient webViewClient = new WebViewClient() {

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

                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("CRM_USER_AGENT", "crm_app");
                    urlConnection.setRequestMethod("POST");

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


                    data = new java.util.Scanner(in).useDelimiter("\\A").next();

                    System.out.println("Data:" + data);


                    urlConnection.getContentType();
                    urlConnection.getContentEncoding();
                    urlConnection.getContentEncoding();

                    urlConnection.disconnect();



                    return new WebResourceResponse("text/html","UTF-8", in);

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

                    return null;
                }


            }
        };


        wv.setWebViewClient(webViewClient);

        pd.setVisibility(View.INVISIBLE);
        wv.setVisibility(View.VISIBLE);
        wv.loadUrl("https://someurl.com");

以上不起作用，我无法确定原因 - 我得到一个空白的webview。当我从data打印值时，我会得到一些未知字符。

我也在尝试向Webview请求添加自定义标头，这就是我偶然发现您的问题的原因。我发现另一个问题解决了与an answer that worked for me类似的问题，所以它也可能会为你解决问题：

我有同样的问题。如果删除


urlConnection.disconnect（）;


它有效。

使用HttpUrlConnection自定义WebViewClient - 为每个请求添加标头（WebView）
