I am using the following code to sign the base string. Is this
correct?
My problem is, I generate the base string using OAuth playground and
when I create the signature it does not match with the one generated
in the playground and my subsequent request fails with HTTP error code
400
What is wrong in this?
public final class Encoder {
private static final String SIGNING_ALGORITHM = "HmacSHA1";
private Encoder() {
// nothing to do.
}
public static String sign(final String source, final String key) {
if (key == null) {
throw new IllegalArgumentException("key cannot be null");
}
Mac mac = null;
try {
mac = Mac.getInstance(SIGNING_ALGORITHM);
mac.init(new SecretKeySpec(key.getBytes(),
SIGNING_ALGORITHM));
} catch (Exception e) {
throw new RuntimeException(e);
}
final byte[] result = mac.doFinal(source.getBytes());
final String signature = new String(Base64.encodeBase64
(result));
return signature;
}
}
