TrustyPay.Crypto.Banks.CMB 0.0.3

招行免前置机接口客户端类

1. 下载招行国密算法密钥生成工具
2. 运行SMKeyTool.exe程序并点击"生成密钥"按钮
3. 保存好银行公钥/用户公钥/用户私钥/用户对称密钥
4. CmbHttpClient类的使用示例：

    using System.Net.Http;
    using TrustyPay.Crypto;

    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编号，需要有相应的权限，用于调用云直联接口。
    );

    var client = new CmbHttpClient(
        "https://招行生产/测试接口地址",
        config);

    try
    {
        return await client.PostAsync<SubaccountBalanceQuery, 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)
    {
        throw;
    }
    catch (HttpRequestException se)
    {
        throw;
    }
