Korzystam z najnowszego emulatora pamięci masowej Azure SDK. Próbuję podpisać prośbę do mojej kropelki. Po uruchomieniu poniższego kodu otrzymuję błąd autoryzacji.

Nie mogę zrozumieć, co jest nie tak, chociaż kilkakrotnie sprawdzałem, czy kod jest zgodny ze specyfikacjami dostępu blob Azure SDK.

Oto wyjście konsoli:

GET



x-ms-date:Sun, 23 Sep 2012 04:04:07 GMT
/devstoreaccount1/tweet/?comp=list
SharedKey devstoreaccount1:Hx3Pm9knGwCb4Hs9ftBX/+QlX0kCGGlUOX5g6JHZ9Kw=
Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

Oto kod:

public static void signRequest(HttpURLConnection request, String account, String key) throws Exception
{
    SimpleDateFormat fmt = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss");
    fmt.setTimeZone(TimeZone.getTimeZone("GMT"));
    String date = fmt.format(Calendar.getInstance().getTime()) + " GMT";

    StringBuilder sb = new StringBuilder();
    sb.append("GET\n"); // method
    sb.append('\n'); // md5 (optional)
    sb.append('\n'); // content type
    sb.append('\n'); // legacy date
    sb.append("x-ms-date:" + date + '\n'); // headers
    sb.append(request.getURL().getPath() + "/tweet/?comp=list"); // resource TODO: "?comp=..." if present

    System.out.println(sb.toString());
    Mac mac = Mac.getInstance("HmacSHA256");
    mac.init(new SecretKeySpec(Base64.decode(key), "HmacSHA256"));
    String authKey = new String(Base64.encode(mac.doFinal(sb.toString().getBytes("UTF-8"))));
    String auth = "SharedKey " + account + ":" + authKey;
    request.setRequestProperty("x-ms-date", date);
    request.setRequestProperty("Authorization", auth);
    request.setRequestMethod("GET");
    System.out.println(auth);
}



public static void main(String args[]) throws Exception
{
     String account = "devstoreaccount1";
     String key = "Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==";
     HttpURLConnection connection = (HttpURLConnection) (new URL("http://localhost:10000/devstoreaccount1")).openConnection();
     signRequest(connection, account, key);
     connection.connect();
     System.out.println(connection.getResponseMessage());
 }

Po otrzymaniu opinii od Gaurav i Smarx, oto kod, wciąż otrzymuję ten sam błąd. Czy możesz mi pokazać jakiś kod? Trudno zrozumieć inaczej.

    public static void sign(HttpURLConnection request, String account, String key, String url) throws Exception

        sb.append('\n'); // md5 (optional)

        sb.append('\n'); // legacy date
        sb.append("x-ms-date:" + date + '\n'); // headers
