使用 ASP.NET Core 反序列化 HttpClient 的 Json 响应

Question

I am calling a third-party API with HttpClient GET Request and it works fine. The response is quite complex of objects. All I want to do is to extract a specific attribute within these objects. Here is the response Json

  "creationTime": "2021-11-06T12:22:49.602Z",
  "currency": "USD",
  "customer": {
    "firstName": "xxxx"
  },
  "id": "xxxx",
  "lastUpdatedTime": "2021-11-06T12:22:51.689Z",
  "merchant": "xxx",
  "merchantAmount": 33,
  "merchantCategoryCode": "5311",
  "merchantCurrency": "USD",
  "reference": "XX",
  "result": "SUCCESS",
  "sourceOfFunds": {
    "provided": {
      "card": {
        "brand": "MASTERCARD",
        "expiry": {
          "month": "X",
          "year": "XX"
        },
        "fundingMethod": "DEBIT",
        "nameOnCard": "XXX",
        "number": "XXXXX123",
        "scheme": "MASTERCARD",
        "storedOnFile": "NOT_STORED"
      }
    },
    "type": "CARD"
  },
  "status": "CAPTURED",
  "totalAuthorizedAmount": 33,
  "totalCapturedAmount": 33,
  "totalRefundedAmount": 0,
  "transaction": [
    {
      "3DSecure": {
        "acsEci": "02",
        "authenticationToken": "XXXX+XXXX=",
        "paResStatus": "Y",
        "veResEnrolled": "Y",
        "xid": "mmmXXX"
      },
      "3DSecureId": "XXX",
      "authorizationResponse": {
        "cardSecurityCodeError": "M",
        "commercialCardIndicator": "1",

        "stan": "22443",
        "time": "122249",
        "transactionIdentifier": "014VPH"
      },
      "customer": {
        "firstName": "XXXX"
      },
      "device": {
     
      },
      "gatewayEntryPoint": "CHECKOUT",
      "merchant": "XXXX",
      "order": {
        "amount": 33,
        "chargeback": {
          "amount": 0,
          "currency": "USD"
        },
        "creationTime": "2021-11-06T12:22:49.602Z",

        "lastUpdatedTime": "2021-11-06T12:22:51.689Z",
        "merchantAmount": 33,
        "merchantCategoryCode": "xxx",
        "merchantCurrency": "IQD",
        "reference": "243",
        "status": "CAPTURED",
        "totalAuthorizedAmount": 33,
        "totalCapturedAmount": 33,
        "totalRefundedAmount": 0
      },
      "response": {
        "acquirerCode": "00",
        "acquirerMessage": "Approved",
        "cardSecurityCode": {
          "acquirerCode": "M",
          "gatewayCode": "MATCH"
        },
        "gatewayCode": "APPROVED"
      },
      "result": "SUCCESS",
      "sourceOfFunds": {
        "provided": {
          "card": {
            "brand": "MASTERCARD",
            "expiry": {
              "month": "x",
              "year": "xx"
            },
            "fundingMethod": "DEBIT",
            "nameOnCard": "xxxxx",
            "number": "xxxxxx",
            "scheme": "MASTERCARD",
            "storedOnFile": "NOT_STORED"
          }
        },
        "type": "CARD"
      },
      "timeOfLastUpdate": "2021-11-06T12:22:51.689Z",
      "timeOfRecord": "2021-11-06T12:22:49.617Z",
 
    }
  ]
} 

I'd like to extract "status": "CAPTURED" and "acquirerCode": "00" . here is what I tried

  var client = new HttpClient();
            string _ContentType = "application/json";
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(_ContentType));
            client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", base64EncodedAuthenticationString);

            var _UserAgent = "d-fens HttpClient";
            client.DefaultRequestHeaders.Add("User-Agent", _UserAgent);
            HttpResponseMessage response;
            response = await client.GetAsync(api_URL);
  
            var resContent =  JsonConvert.DeserializeObject(await response.Content.ReadAsStringAsync());
 
            var content = response.Content.ReadAsStringAsync().Result;
 
            return Ok(resContent);

Extracting these values would solve the issue I'm facing. Thanks in advance

Answer 1

if you need just this 2 values the easiest way is

var json = response.Content.ReadAsStringAsync().Result;

var result = JObject.Parse(json);
var status= result["status"];
var acquirerCode= result["transaction"][0]["response"]["acquirerCode"];

output

CAPTURED
00

And there is a hard way

var json = response.Content.ReadAsStringAsync().Result;

 var jsonDeserialized=JsonConvert.DeserializeObject<Data>(json);

 var status= jsonDeserialized.Status;
     
var acquirerCode=jsonDeserialized.Transaction.Select(t =>  t.Response.AcquirerCode).FirstOrDefault();
