(C#) HTTP POST JSON and Parse JSON ResponseDemonstrates how to send a JSON POST and then parse the JSON response.
// This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.JsonObject json = new Chilkat.JsonObject(); bool success = json.LoadFile("qa_data/json/jsonBodyForHttpPost.json"); if (success != true) { Debug.WriteLine(json.LastErrorText); return; } Chilkat.Http http = new Chilkat.Http(); Chilkat.HttpResponse resp = http.PostJson2("https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums","application/json",json.Emit()); if (http.LastMethodSuccess != true) { Debug.WriteLine(http.LastErrorText); return; } Chilkat.JsonObject jsonResp = new Chilkat.JsonObject(); jsonResp.Load(resp.BodyStr); jsonResp.EmitCompact = false; Debug.WriteLine(jsonResp.Emit()); // The JSON response to be parsed looks like this: // { // "LifeAmount": 513.85, // "LifeResidualAmount": 123.38, // "CriticalIllnessAmount": 0, // "CriticalIllnessResidualAmount": 0, // "DisabilityAmount": 881.70, // "PolicyFee": 0.00, // "PolicyFeeSecondary": 0, // "PolicyFeeHidden": 50.00, // "PolicyFeeHiddenSecondary": 0 // } // We can get the floating point numbers as strings. Then convert to double // using the appropriate string-to-double conversion for your programming language. // For example, in C++ use atof. In C# use Convert.ToDouble. string lifeAmount = jsonResp.StringOf("LifeAmount"); string lifeResidualAmount = jsonResp.StringOf("LifeResidualAmount"); Debug.WriteLine("LifeAmount = " + lifeAmount); Debug.WriteLine("LifeResidualAmount = " + lifeResidualAmount); |
