Question

注意：我们的Host应用程序调用此JAR文件（实际上是 class）仅支持JVM 1.5。由于代码的触发器来自应用程序，我们没有任何其他去限制我们的Java 代码与JDK 1.5的兼容性。

以下是我尝试过的代码：

        String webPage = "https://api.twilio.com/2010-04-01/Accounts";
        URL url = new URL(webPage);
        URLConnection urlConnection = url.openConnection();
        urlConnection.setRequestProperty("Authorization", "Basic BASE64ECONDED_STRING_OF_LENGTH_93_CHARACTERS_WITHOUT_ANY_WHITESPACE");
        //((HttpURLConnection) urlConnection).setRequestMethod("GET");//I get same error with or without this
        InputStream is = urlConnection.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);

        int numCharsRead;
        char[] charArray = new char[1024];
        StringBuffer sb = new StringBuffer();
        while ((numCharsRead = isr.read(charArray)) > 0) {
            sb.append(charArray, 0, numCharsRead);
        }
        String result = sb.toString();

        System.out.println("*** BEGIN ***");
        System.out.println(result);
        System.out.println("*** END ***");

我一直收到的错误是：

看起来Java 1.5中不支持基本授权。完全相同的代码适用于Java 1.7。我也得到了成功的回应。有没有办法让它在Java 1.5中运行？

使用Java的基本授权（1.5）
