TrustyPay.Crypto.Banks.CMB 0.0.8

招行免前置机接口客户端类

1. 使用KeyGenerator类生成招行需要的密钥信息：

   using TrustyPay.Crypto.Banks.CMB;
   
   var generator = new KeyGenerator("<银行公钥>");
   Console.WriteLine("招行密钥设置信息 => 用户公钥:{0}, 加密后对称密钥:{1} ",
        generator.SM2PublicKey, generator.SM4KeyEncrypted);
   Console.WriteLine("招行接口调用信息 => 用户私钥:{0}, 对称密钥:{1} ",
        generator.SM2PrivateKey, generator.SM4Key);
   

2. 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;

3. 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;

4. CmbHttpClient类的使用示例：

       using TrustyPay.Crypto;
       using TrustyPay.Crypto.Http;
       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(re.Message);
           return;
       }
   

5. SubaccountBalanceQuery类定义:

       using Newtonsoft.Json;
       using TrustyPay.Crypto.Banks.CMB;
   
       public class SubaccountBalanceQuery : IFunctionCode
       {
           [JsonProperty("ntdmabalx")]
           public AccountInfo[] Account { get; set; }
   
           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")]
               public string NextLink { get; set; }
           }
       }
   

6. SubaccountBalanceResult类定义:

       using Newtonsoft.Json;
   
       public class SubaccountBalanceResult

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

           }
   
           public class BalanceItem
           {
               [JsonProperty("accnbr")]
