HTTP POST JSON and Parse JSON Response

See more HTTP Examples

Demonstrates how to send a JSON POST and then parse the JSON response. Go

    success := false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    json := chilkat.NewJsonObject()

    success = json.LoadFile("qa_data/json/jsonBodyForHttpPost.json")
    if success == false {
        fmt.Println(json.LastErrorText())
        json.DisposeJsonObject()
        return
    }

    http := chilkat.NewHttp()

    resp := chilkat.NewHttpResponse()
    success = http.HttpJson("POST","https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums",json,"application/json",resp)
    if success == false {
        fmt.Println(http.LastErrorText())
        json.DisposeJsonObject()
        http.DisposeHttp()
        resp.DisposeHttpResponse()
        return
    }

    jsonResp := chilkat.NewJsonObject()
    jsonResp.Load(resp.BodyStr())

    jsonResp.SetEmitCompact(false)
    fmt.Println(*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.  
    lifeAmount := jsonResp.StringOf("LifeAmount")
    lifeResidualAmount := jsonResp.StringOf("LifeResidualAmount")

    fmt.Println("LifeAmount = ", *lifeAmount)
    fmt.Println("LifeResidualAmount = ", *lifeResidualAmount)

    json.DisposeJsonObject()
    http.DisposeHttp()
    resp.DisposeHttpResponse()
    jsonResp.DisposeJsonObject()
