I am having a json deserialization issue in my own self-service.
I have a test page that calls self-serving REST with JSON, here is the code:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script type="text/javascript">
function doFunction() {
xhr = new XMLHttpRequest();
var url = "https://localhost:1234/business/test/testing2/endpoint";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-type", "application/json");
xhr.onreadystatechange = function () {
if (xhr.readyState == 4 && xhr.status == 200) {
var json = JSON.parse(xhr.responseText);
alert(json);
}
}
var data = JSON.stringify({ testing : "test" });
xhr.send(data);
}
</script>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="clickMe" type="button" value="clickme" onclick="doFunction();" />
</div>
</form>
</body>
</html>
And here is my self-service interface and contracts:
[DataContract]
public class OperationInput
{
[DataMember]
public string testing { get; set; }
}
[DataContract]
public class OperationOutput
{
[DataMember]
public int Status { get; set; }
[DataMember]
public string Message { get; set; }
[DataMember]
public string AddInfo { get; set; }
[DataMember]
public string PartnerID { get; set; }
[DataMember]
public string SessionID { get; set; }
}
[ServiceContract]
interface IRegisterOperation
{
[OperationContract]
[WebInvoke(UriTemplate = "/endpoint",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json, Method = "*")]
OperationOutput Operation(OperationInput order);
}
And here is the implementation of the interface:
public class RegisterOperation : IRegisterOperation
{
public OperationOutput Operation(OperationInput input)
{
System.IO.StreamWriter file = new System.IO.StreamWriter("c:\\testing.txt", false);
file.WriteLine(input.testing);
file.Close();
OperationOutput output = new OperationOutput();
output.Status = 200;
output.Message = "The action has been successfully recorded on NAVe";
output.AddInfo = "";
return output;
}
}
I create self-host using this code:
host = new ServiceHost(implementationType, baseAddress);
ServiceEndpoint se = host.AddServiceEndpoint(endpointType, new WebHttpBinding(WebHttpSecurityMode.Transport), "");
se.Behaviors.Add(new WebHttpBehavior());
host.Open();
Using debug, I notice that it hits a breakpoint inside my service, so calling localhost works, but the input parameter is NULL, as you can see in the image below:
Here are 2 images capturing a POST request with JSON on the violin:
Do you have any idea why I am getting null? instead of the string "test", how do I do when called in javascript?
Thank you very much in advance;)
