webView中获取response头部信息

webView中获取response头部信息

转自：

Neither WebView nor WebViewClient provide methods to do that, Though, you can try to implement that manually. You can do something like this:

private WebView webview;
public void onCreate(Bundle icicle){// bla bla bla// here you initialize your webviewwebview = new WebView(this);webview.setWebViewClient(new YourWebClient());
}// this will be the webclient that will manage the webview
private class YourWebClient extends WebViewClient{// you want to catch when an URL is going to be loadedpublic boolean  shouldOverrideUrlLoading  (WebView  view, String  urlConection){// here you will use the url to access the headers.// in this case, the Content-Length oneURL url;URLConnection conexion;try {url = new URL(urlConection);conexion = url.openConnection();conexion.setConnectTimeout(3000);t();// get the size of the file which is in the header of the requestint size = ContentLength();}// and here, if you want, you can load the page normallyString htmlContent = "";HttpGet httpGet = new HttpGet(urlConection);// this receives the responseHttpResponse response;try {response = ute(httpGet);if (StatusLine().getStatusCode() == 200) {// la conexion fue establecida, obtener el contenidoHttpEntity entity = Entity();if (entity != null) {InputStream inputStream = Content();htmlContent = convertToString(inputStream);}}} catch (Exception e) {}webview.loadData(htmlContent, "text/html", "utf-8");return true;}public String convertToString(InputStream inputStream){StringBuffer string = new StringBuffer();BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));String line;try {while ((line = adLine()) != null) {string.append(linea + "n");}} catch (IOException e) {}String();}
}
