HttpURLConnection-“ https：”和“ http：”

HttpURLConnection-“ https：//”和“ http：//”

除非您使用user2558882的想法，否则除非有其他工具可以为您提供网站图标，否则您将必须同时检查http和https网址。没有其他方法可以做到这一点。这是使用网络的困难之一。

也许以不同的方式看待您的代码并将您尝试做的事情分解为更小，更易于管理的部分会更好一些？

public void getFavicon(String host) {    URL httpUrl = this.getHttpUrl(host + "/favicon.ico");    Bitmap favicon = this.getBitmap(httpUrl);    if (favicon == null) {        URL httpsUrl = this.getHttpsUrl(host + "/favicon.ico");        favicon = this.getBitmap(httpsUrl);    }    if (favicon == null) {        throw new FaviconMissingException("Unable to find favicon for host: " + host);    }    return favicon;}public URL getHttpUrl(String uri) throws MalformedURLException {    // There are better ways of building a url then string concationation.    return new URL("http://" + uri);}public URL getHttpsUrl(String uri) throws MalformedURLException {    // There are better ways of building a url then string concationation.    return new URL("https://" + uri);}public Bitmap getBitmap(URL url) {    InputStream inputStream = getInputStream(url);    Bitmap bitmap = BitmapFactory.depreStream(inputStream);    return bitmap}public InputStream getInputStream(URL url) {    // Please use a real connection library like HTTPClient here!    // HttpClient will handle timeouts, redirects, and things like that for you.    HttpURLConnection connection = (HttpURLConnection) url.openConnection();    connection.setDoInput(true);    connection.connect();    return connection.getInputStream();}

顺便说一句，关注一个或两个连接需要花费更多时间，然后编写代码以发出两个请求。我几乎保证Google会根据需要发出两个请求。如果它对Google足够好，对我来说也足够好。

最后，如果您开始发现发出两个请求确实花费了太多时间，则可以采取一些措施来提高性能。
