TrustyPay.Crypto.Banks.CMB 0.0.4

招行免前置机接口客户端类

1. 从招商银行企业开放平台下载国密算法密钥生成工具;
2. 双击运行国密算法密钥生成工具SMKeyTool.exe并点击"生成密钥"按钮;
3. 妥善保管好生成的银行公钥/用户公钥/用户私钥/用户对称密钥;
4. 将上述的用户公钥和加密版对称密钥保存到招商银行银企直联->设置与授权->密钥设置;
5. CmbHttpClient类的使用示例：

    
    using TrustyPay.Crypto;
    using TrustyPay.Crypto.Banks.CMB;

    var config = new Config(
        "<用户私钥>",
        "<银行公钥>",
        "<用户对称密钥>",
        "用户编号" // 用户编号来自招行企业网银后台设置的用户[U盾编号]，此用户需要有相应的接口调用权限。
    );

    var client = new CmbHttpClient(
        "https://招商银行接口生产地址/测试接口地址",
        config);

    SubaccountBalanceResult result;
    try
    {
        result = await client.PostAsync<SubaccountBalanceResult>(
            string.Empty,
            new SubaccountBalanceQuery("用户招行账号", "记账子单元编号", "续传字段"),
            System.Threading.CancellationToken.None);
    }
    catch (InvalidSignatureException se)
    {
        Console.WriteLine("signature is incorrect!!!");
        return;
    }
    catch (HttpResponseException re)
    {
        Console.WriteLine("some errors occured!!!");
        return;
    }

        public string FuncCode => "NTDMABAL";

        public SubaccountBalanceQuery(
            string account,
            string subaccount,
            string nextLink)
        {
            Account = new[]{
                new AccountInfo
                {
                    Account = account,
                    Subaccount = subaccount,
                    NextLink = nextLink
                }
            };
        }

        public class AccountInfo
        {
            [JsonProperty("accnbr")]
            public string Account { get; set; }

            [JsonProperty("dmanbr")]
            public string Subaccount { get; set; }

            [JsonProperty("ctnkey")]
