签名方法

测试环境logistic_provider_id和secretKey线下提供

如果使用正确的签名方法有时能请求成功有时报签名失败，可能是发请求时自动urldecode导致+变成了空格，可以对data_digest和logistics_interface进行urlencode后再发送请求

JAVA

/**
 *
 * @param content 加密报文
 * @param charset 编码，UTF-8
 * @param secretKey 密钥
 * @return
 */

public static String doSign(String content, String charset, String secretKey) {
   String sign = "";
   content = content + secretKey;
   try {
      MessageDigest md = MessageDigest.getInstance("MD5");
      md.update(content.getBytes(charset));
      sign = new String(Base64.encodeBase64(md.digest()), charset);
   } catch (Exception e) {
      throw new RuntimeException(e);
   }
   return sign;
}

PHP

$content = [ "testkey" => "testkey", "testdata" => "testdata" ];
$appSecret = '8026ny111111111111'; // 秘钥
$digest = base64_encode(md5(json_encode($content).$appSecret, true)); //生成签名

public static string DoSign(string content, string charset, string appSecret)
{
    string toSignContent = content + appSecret;

    System.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create();

    byte[] inputBytes = System.Text.Encoding.GetEncoding(charset).GetBytes(toSignContent);
    byte[] hash = md5.ComputeHash(inputBytes);

    return System.Convert.ToBase64String(hash);
}
