ZTO接口签名方式

C#

var checkBytes = Encrypt.GetMd5HashBytes(data + key, encoding);
var dataDigest = Convert.ToBase64String(checkBytes);

JAVA

import org.apache.commons.codec.binary.Base64;
import org.apache.commons.codec.digest.DigestUtils;
import java.nio.charset.Charset;

public class DigestUtil {
    public static String md5WithBase64(String str, String charset) {
        return base64(md5Bytes(str, charset));
    }

    public static String base64(byte[] bytes) {
        return Base64.encodeBase64String(bytes);
    }

    public static byte[] md5Bytes(String str) {
        return md5Bytes(str, "UTF-8");
    }

    public static byte[] md5Bytes(String str, String charset) {
        return DigestUtils.md5(str.getBytes(Charset.forName(charset)));
    }

    public static String md5Str(String str) {
        return DigestUtils.md5Hex(str);
    }

    public static String md5Str(String str, String charset) {
        return DigestUtils.md5Hex(str.getBytes(Charset.forName(charset)));
    }

    public static String decodeBase64(String content) {
        return new String(Base64.decodeBase64(content));
    }

    public static String decodeBase64(String content, String encode) {
        return new String(Base64.decodeBase64(content), Charset.forName(encode));
    }
}

PHP

$data="你好";
$key="签名";
$data_digest = base64_encode(md5($data.$key,TRUE));

java版的签名用 md5WithBase64方法
