访问带有用户名、密码的URL

很简单，举例如下：

HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); urlConnection.setRequestMethod("GET"); urlConnection.setDoOutput(false); urlConnection.setConnectTimeout(10 * 1000); urlConnection.setReadTimeout(10 * 1000); urlConnection.setRequestProperty("Connection", "Keep-Alive"); String username = "[username]"; String password = "[password]"; String input = username + ":" + password; String encodingInput = Base64.encodeToString(input.getBytes(), 0); urlConnection.setRequestProperty("Authorization", "Basic " + encodingInput); urlConnection.connect();
