Calling local WFC service from ASP.net AJAX
Apr 26 2018 9:36 AM
Hey all I am using the following code on my local machine to give me a temporary WCF service:
using
System;
using
System.Windows.Forms;
using
System.ServiceModel;
using
TestService;
namespace
TestClient
{
public
partial
class
Form1 : Form
{
IService1 patientSvc =
null
;
public
Form1()
{
InitializeComponent();
}
private
void
Form1_Load(
object
sender, EventArgs e)
{
EndpointAddress address =
new
EndpointAddress(
new
Uri(
"net.tcp://localhost:2202/PatientService"
));
NetTcpBinding binding =
new
NetTcpBinding();
ChannelFactory
factory =
new
ChannelFactory
(binding, address);
patientSvc = factory.CreateChannel();
}
}
}
And the class1:
using
System;
using
System.Collections.Generic;
using
System.Text;
using
System.ServiceModel;
using
System.Runtime.Serialization;
namespace
TestService
{
[ServiceContract()]
public
interface
IService1
{
[OperationContract]
Patient GetPatient(Int32 index);
[OperationContract]
void
SetPatient(Int32 index, Patient patient);
}
[ServiceBehavior(IncludeExceptionDetailInFaults =
true
)]
public
class
PatientService : IService1
{
Patient[] pat =
null
;
public
PatientService()
{
pat =
new
Patient[3];
pat[0] =
new
Patient();
pat[0].FirstName =
"Bob"
;
pat[0].LastName =
"Chandler"
;
pat[1] =
new
Patient();
pat[1].FirstName =
"Joe"
;
pat[1].LastName =
"Klink"
;
pat[2] =
new
Patient();
pat[2].FirstName =
"Sally"
;
pat[2].LastName =
"Wilson"
;
}
public
Patient GetPatient(Int32 index)
{
if
(index <= pat.GetUpperBound(0) && index > -1)
return
pat[index];
else
return
new
Patient();
}
public
void
SetPatient(Int32 index, Patient patient)
{
if
(index <= pat.GetUpperBound(0) && index > -1)
pat[index] = patient;
}
}
[DataContract]
public
class
Patient
{
string
firstName;
string
lastName;
[DataMember]
public
string
FirstName
{
get
{
return
firstName; }
set
{ firstName = value; }
}
[DataMember]
public
string
LastName
{
get
{
return
lastName; }
set
{ lastName = value; }
}
}
}
This works just fine if I have the call to
PatientService
with a
1
. It shows me the values
Joe
and K
link
.
However, doing the same on my ASP.net website page with the following:
.cs page:
@{
ViewBag.Title = ViewBag.Message;
Layout =
"~/Views/Shared/_Layout.cshtml"
;
}
class
=
"col-sm-offset-2 col-sm-8"
style=
"margin-bottom: 10px; margin-top: 10px; text-align: center;"
>
class
=
"tips btn btn-success btn-outline"
style=
"margin-right: 10px;"
id=
"WCF"
data-tooltip=
"@Html.Raw(tips["
Continue
"])"
>WCF TEST
And the JavaScript:
$(document).ready(function () {
$(
"#WCF"
).on(
"click"
, function () {
$.ajax({
type:
"POST"
,
url: ajaxDirPath +
"WCF"
,
data:
'{"patNum": "1"}'
,
contentType:
"application/json"
,
// content type sent to server
success: ServiceSucceeded,
error: ServiceFailed
});
});
});
function ServiceFailed(result) {
console.log(
'Service call failed: '
+ result.status +
' '
+ result.statusText);
}
function ServiceSucceeded(result) {
resultObject = result.MyFunctionResult;
console.log(
"Success: "
+ resultObject);
}
And the code behind:
[HttpPost]
public
string
WCF(
string
patNum)
{
Dictionary<
string
,
string
> resultsBack =
new
Dictionary<
string
,
string
>();
EndpointAddress address =
new
EndpointAddress(
new
Uri(
"net.tcp://localhost:2202/PatientService"
));
NetTcpBinding binding =
new
NetTcpBinding();
ChannelFactory
factory =
new
ChannelFactory
(binding, address);
IService1 patientSvc = factory.CreateChannel();
Patient patient = patientSvc.GetPatient(Convert.ToInt32(patNum));
if
(patient !=
null
)
{
resultsBack.Add(
"dback"
,
"GOOD"
);
resultsBack.Add(
"return1"
, patient.FirstName);
resultsBack.Add(
"return2"
, patient.LastName);
}
return
JsonConvert.SerializeObject(resultsBack, Formatting.Indented);
}
The
patient
variable is
NULL
for everything it returns back.
What would I be doing incorrectly?
Steps in debug:
This is the steps in debugging from both the javascript and the WCF service:
