我正在编写一个需要与Server通信的JavaScript客户端应用程序。我试图实现API,但我坚持使用一种方法,我需要帮助。
感染我不知道如何将其从Java翻译成JavaScript(我不知道在哪里可以找到用javascript编写的模拟库,这个方法中使用了这个模块库):
import java.security.SignatureException;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
/**
* This class defines common routines for generating
* authentication signatures for AWS requests.
*/
public class Signature {
private static final String HMAC_SHA1_ALGORITHM = "HmacSHA1";
/**
* Computes RFC 2104-compliant HMAC signature.
* * @param data
* The data to be signed.
* @param key
* The signing key.
* @return
* The Base64-encoded RFC 2104-compliant HMAC signature.
* @throws
* java.security.SignatureException when signature generation fails
*/
public static String calculateRFC2104HMAC(String data, String key)
throws java.security.SignatureException
{
String result;
try {
// get an hmac_sha1 key from the raw key bytes
SecretKeySpec signingKey = new SecretKeySpec(key.getBytes(), HMAC_SHA1_ALGORITHM);
// get an hmac_sha1 Mac instance and initialize with the signing key
Mac mac = Mac.getInstance(HMAC_SHA1_ALGORITHM);
mac.init(signingKey);
// compute the hmac on input data bytes
byte[] rawHmac = mac.doFinal(data.getBytes());
// base64-encode the hmac
result = Encoding.EncodeBase64(rawHmac);
} catch (Exception e) {
throw new SignatureException("Failed to generate HMAC : " + e.getMessage());
}
return result;
}
}
此方法来自AWS Documentations: Java Sample Code for Calculating HMAC-SHA1 Signatures
我在问是否有人可以给我一些参考资料(网站),我可以找到用javascript编写的解决方案或模拟库。
我搜索了AWS Documentation and SDK for JavaScript,但我找不到JS中的翻译。
非常感谢。
