I've gotten to a point now where I can receive responses from a client website I've made (for internal use in the company I work at) on my WCF Webservice. But whenever I get a response it's always null.
I've look around for various solutions and none of them seems to fix this issue. I have the following:
[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest, UriTemplate = "/AddNewActivity")]
String AddNewActivity(String jsonObject);
And implemented:
public String AddNewActivity(String jsonObject)
{
return JsonConvert.SerializeObject("Success");
}
Just to test that it works. I set a breakpoint at the above function to read the jsonObject string and see what it looks like. When I read it though, it's null. Always null.
Here is the JavaScript:
function OnModalCreateNewActivityBtnClick() {
var modal = $('#new-activity-modal-body');
var activityMap = {
status: modal.find('#new-activity-modal-status-dropdown').val(),
name: modal.find('#new-activity-modal-name-field').val(),
responsible: modal.find('#new-activity-modal-responsible-field').val(),
department: modal.find('#new-activity-modal-department-dropdown').val(),
startTime: modal.find('#new-activity-modal-datepicker-start').val(),
endTime: modal.find('#new-activity-modal-datepicker-end').val(),
description: modal.find('#editor').cleanHtml(),
axAccounts: modal.find('#new-activity-modal-ax-account-numbers-field').val()
};
var jsonObject = '{ "String": ' + JSON.stringify(activityMap) + '}';
$.ajax({
type: 'POST',
url: 'http://localhost:52535/PUendeligService.svc/AddNewActivity',
data: jsonObject,
contentType: 'application/json; charset=utf-8',
dataType: 'json',
processData: true,
success: function (data, status, jqXHR) {
alert("Success: " + data);
},
error: function (xhr) {
console.log(xhr.responseText);
alert("Error: " + xhr.responseText);
}
});
}
Anyone have any idea why it returns null?
UPDATE
I used Fiddler and the information that leaves the website to the web service is correct. It's a JSON String that Fiddler can read. But the web service still receives a null object.
Let's simplify your sample a bit and start with this
<script type="text/javascript">
function OnModalCreateNewActivityBtnClick() {
var data = {
Status: modal.find('#new-activity-modal-status-dropdown').val(),
Name: modal.find('#new-activity-modal-name-field').val()
};
$.ajax({
type: 'POST',
url: 'Service.svc/AddNewActivity',
data: JSON.stringify(data),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (msg) {
alert(data.Status + ' == ' + msg.Status);
},
error: function (e) {
alert('failed with ' + e.statusText);
}
});
}
</script>
Your activity class
[DataContract]
public class Activity
{
[DataMember]
public String Status
{
get; set;
}
[DataMember]
public String Name
{
get; set;
}
}
Implementation
[WebInvoke(Method ="POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "AddNewActivity/")]
public Activity AddNewActivity(Activity activity)
{
// your stuff
return activity;
}
Lastly, since you didn't show your configuration let's assume the following
<system.serviceModel>
<services>
<service name="PUendelig.Service" behaviorConfiguration="serviceBehavior">
<endpoint address="" binding="webHttpBinding" contract="PUendelig.IService" behaviorConfiguration="web"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="serviceBehavior">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="web">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https"/>
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
