【问题描述】：
我正在尝试生成 HMAC 签名。这是为了与信用卡公司进行验证。下面是我生成 HMAC 签名的代码：
public string APISecurityKey(Identity postParameters)
{
String secretAccessKey = "secretkey";
string data = "message";
byte[] secretKey = Encoding.UTF8.GetBytes(secretAccessKey);
HMACSHA256 hmac = new HMACSHA256(secretKey);
hmac.Initialize();
byte[] bytes = Encoding.UTF8.GetBytes(data);
byte[] rawHmac = hmac.ComputeHash(bytes);
return Convert.ToBase64String(rawHmac);
}
他们要求我用 JSON 请求替换消息字段（提供的 JSON 应将所有回车换行符序列替换为空格字符）。我的对象看起来像这样：
public class Identity
{
public List<Header> header { get; set; }
public string firstName { get; set; }
public string LastName { get; set; }
public string middleName { get; set; }
public string address { get; set; }
public string mothersName { get; set; }
public string DriversLic { get; set; }
public DateTime insertTime { get; set; }
public string Status { get; set; }
public string city { get; set; }
public string state { get; set; }
public string zip { get; set; }
public DateTime UpdatedOn { get; set; }
}
}
public class Header
{
public string tenantId { get; set; }
public string requestType { get; set; }
public string clientReferenceId { get; set; }
public string expRequestId { get; set; }
public string txnId { get; set; }
public string messageTime { get; set; }
public string options { get; set; }
}
给我的消息示例是这样的：
{"tenantId": "TENANT1","request Type": "Simulator","clientRefere
nceId": "Hunter + ProveID","expRequestId": "333","messageTim
e": "2016-08-04T22:13:07Z","options": {"workflow": "wf1","model
Type":"mt1","responseType":1,"Responses": {…}}}
我不确定如何在我的 JSON 消息中包含tenantId、tenantId、expRequestId、选项。我对 JSON 很陌生。我有这个部分代码：
public static async Task createJSON( Identity postParameters)
{
var tmpRequest = new HttpRequestMessage();
tmpRequest.Content = new StringContent(JsonConvert.SerializeObject(postParameters));
tmpRequest.Content.Headers.Add("tenantId", "V123456");
tmpRequest.Content.Headers.Add("requestType", "PreciseIdOnly");
}
postParameters 是我的带有值的 Identity 对象。如何创建包含 tenantId、tenantId、expRequestId 和对象的 JSON，以便我可以将该 JSON 值放入 APISecurityKey 方法的消息中。下面是我需要创建的测试 JSON 文件：
{
"header": {
"tenantId": "V123456",
"requestType": "Precise",
"clientReferenceId": "11111111",
"RequestId": "",
"txnId": "",
"messageTime": "2020-05-28T00:00:02Z",
"options": {}
},
"payload": {
"control": [
{
"option": "SUBSCRIBER_PREAMBLE",
"value": "wer"
},
{
"option": "SUBSCRIBER_OPERATOR_INITIAL",
"value": "WS"
},
{
"option": "SUBSCRIBER_SUB_CODE",
"value": "1111111"
},
{
"option": "PID_USERNAME",
"value": "demo"
},
{
"option": "PID_PASSWORD",
"value": "password"
},
{
"option": "PRODUCT_OPTION",
"value": "11"
}
],
"contacts": [{
"id": "APPLICANT_CONTACT_ID_1",
"person": {
"typeOfPerson": "",
"personIdentifier": "",
"personDetails": {
"dateOfBirth": "1990-12-11",
"yearOfBirth": "",
"age": "",
"gender": "",
"noOfDependents": "",
"occupancyStatus": "",
"mothersMaidenName": "",
"spouseName": ""
},
"names": [{
"id": "",
"firstName": "Test1",
"middleNames": "D",
"surName": "Test2",
"nameSuffix": ""
}]
},
"addresses": [{
"id": "Main_Contact_Address_0",
"addressType": "CURRENT",
"poBoxNumber": "",
"street": "2312 Test Drve",
"street2": "",
"postTown": "test",
"postal": "49548",
"stateProvinceCode": "CA"
}],
"identityDocuments": [{
"documentNumber": "123456789",
"hashedDocumentNumber": "",
"documentType": "SSN"
}]
}]
}
}
我想使用对象在 C# 中生成与上面示例相同的 JSOn。
任何帮助将不胜感激。

信用卡公司是否提供了您需要遵守的某种规范或文档？如果有，可以分享一下吗？很难从您的问题中看出预期的输出应该是什么。
