Http连接失败401

Question

我正在使用Microsoft认知服务器将其文本转换为语音。

我的讲师为我提供了此Java程序来建立HTTP连接。

每当我运行httpConnect方法时，都会得到Connection to the Internet has failed. Please try again.异常。我对代码的了解不多，无法知道为什么会发生这种情况。

据我所知，该服务的密钥都是最新的。

堆栈跟踪：

java.io.IOException: Server returned HTTP response code: 401 for URL: https://speech.platform.bing.com/synthesize

代码：

public class HttpConnect {
final static int TIMEOUT  = 10000; /* ms  */
final static int BUFFSIZE = 4096; /* 4KB */

public static byte[] httpConnect(String method, String url, String[][] headers, byte[] body) {
    try {
        /*
        * Setup connection.
        */
        URL u = new URL( url );
        HttpURLConnection conn = (HttpURLConnection) u.openConnection();

        conn.setRequestMethod( method );
        conn.setDoInput ( true );
        conn.setDoOutput( true );
        conn.setConnectTimeout( TIMEOUT );
        conn.setReadTimeout   ( TIMEOUT );
        for ( int i = 0; i < headers.length; i++ ) {
            conn.setRequestProperty( headers[ i ][ 0 ], headers[ i ][ 1 ] );
        }
        conn.connect();

        /*
        * Send data.
        */
        DataOutputStream dos = new DataOutputStream( conn.getOutputStream() );
        dos.write( body );
        dos.flush();
        dos.close();

        /*
        * Receive data.
        */
        DataInputStream       dis = new DataInputStream( conn.getInputStream() );
        ByteArrayOutputStream bos = new ByteArrayOutputStream();

        byte[] buffer = new byte[ BUFFSIZE ];
        for (;;) {
            int n = dis.read( buffer );
            if ( n > 0 ) {
                bos.write( buffer, 0, n );
            } else {
                break;
            }
        }

        byte response[] = bos.toByteArray();
        dis.close();

        /*
        * Teardown connection.
        */
        conn.disconnect();

        return response;


    } catch ( SocketTimeoutException ex ) {
        System.out.println( "Connection to the Internet has timed out. Please try again." ); //Edited exception - Josh
        return null;

    } catch ( Exception ex ) {
        System.out.println( "Connection to the Internet has failed. Please try again. " ); //Edited exception - Josh
        ex.printStackTrace();
        return null;
    }
}
