用JAVA生成各种凭证代码

1 上传凭证：

import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import com.qiniu.util.StringUtils;
import com.qiniu.util.UrlSafeBase64;

public class TokenUpload {  

    public static void tokenupload() throws NoSuchAlgorithmException, InvalidKeyException{
        String ACCESS_KEY = "AK";
        String SECRET_KEY = "SK";
//      String putpolicy = "{\"scope\":\"javademo\",\"deadline\":1457843866}";
        String putpolicy = "{\"scope\":\"thinkox-shang:sdfsdf.jpg\",\"deadline\":1441940419}";
        String t3 = UrlSafeBase64.encodeToString(putpolicy);
        Mac mac = javax.crypto.Mac.getInstance("HmacSHA1");
        mac.init(new SecretKeySpec(StringUtils.utf8Bytes(SECRET_KEY),"HmacSHA1"));
        String t2 = UrlSafeBase64.encodeToString(mac.doFinal(StringUtils.utf8Bytes(t3)));
        System.out.println(ACCESS_KEY+":"+t2+":"+t3);
    }

    public static void main(String args[]) throws InvalidKeyException, NoSuchAlgorithmException{
        tokenupload();
    }

}
