how to retrieve json or xml response from wcf rest service

Question

User-336392218 posted

Hi,

I have a wcf rest service and I'd like to receive data in json or xml based upon contet type of request.

 

this is the web.config file of the wcf service:

 

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
    <standardEndpoints>
      <webHttpEndpoint>
        <standardEndpoint name="" helpEnabled="true" 
                          automaticFormatSelectionEnabled="true" 
                          defaultOutgoingResponseFormat="Json"
                          crossDomainScriptAccessEnabled="true"></standardEndpoint>
      </webHttpEndpoint>
    </standardEndpoints>
  </system.serviceModel>

I've tested the service with a console app and it works fine:

when I set  req.ContentType = "text/json" the result is json.

when I set  req.ContentType = "text/xml" the result is xml

 

In asp.net script code using jquery I cannot obtain the same behaviour:

$(document).ready(function () {
            $.ajax({
                cache: false,
                url: "http://localhost:28660/RestService",
                type: "GET",
                contentType: "application/json; charset=utf-8",
                dataType: "jsonp",
                processData: false,
                error: function (xhr) {
                    console.log(xhr.responseText);
                },
                success: function (result) {
                    console.log(result);
                }
            });

        });

using the code above I would like to read data in json but I always receive xml formatted data.

 

need help. thank you.

you can use 

    $.ajax({
            type: "GET",
            dataType: "json",
            contentType: "application/json; charset=utf-8",

or

I use

dataType: "jsonp"

because I need it to be cross domain.

 

I also tried with

contentType: "application/json; charset=utf-8"

 

but the response from the server is alway xml.

Hi, please try remove contentType etc information:

$.ajax({
    url: 'http://localhost:8732/Service1/data/10',
    dataType: 'jsonp',
    error: function(req, status, ex) {
        // your code here
    },
