使用ASP.NETCore對HttpClient的Json回應進行消毒-有解無憂

我正在使用 HttpClient GET 請求呼叫第三方 API，它作業正常。回應是相當復雜的物件。我想要做的就是提取這些物件中的特定屬性。這是回應 Json

  ]
}

我想提取"status": "CAPTURED"和 "acquirerCode": "00"。這是我嘗試過的

  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);

提取這些值將解決我面臨的問題。提前致謝

uj5u.com熱心網友回復：

如果您只需要這 2 個值，最簡單的方法是

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

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

輸出

CAPTURED
00

并且有一條艱難的路

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();
