Wcf – .NET SOAP Web Service return JSON

asmxasp.netmobilewcfweb services

I need to prepare a .Net SOAP Web Service which returns JSON format, we have to use those service in iPad & Android.

I searched a lot but found only WCF Restful service that return JSON and ASMX SOAP service that return XML.

Please help me to prepare a .Net SOAP web service which returns JSON data either WCF or ASMX (WCF recommended).

If possible please also let me know what is the standard format (WCF REST return JSON, WCF SOAP return JSON, ASMX SOAP return XML, etc.) to use .NET web-services with iPad/iPhone & Android.

Using WCF it is trivial to return JSON, and IOS developers will love you if you avoid SOAP. Since you didn't specify a version of .NET you require, I will point you to the latest and greatest feature called Web API. See the tutorial here http://www.asp.net/web-api/overview/getting-started-with-aspnet-web-api/tutorial-your-first-web-api

Jquery – How to format a Microsoft JSON date

eval() is not necessary. This will work fine:

var date = new Date(parseInt(jsonDate.substr(6)));

The substr() function takes out the /Date( part, and the parseInt() function gets the integer and ignores the )/ at the end. The resulting number is passed into the Date constructor.

I have intentionally left out the radix (the 2nd argument to parseInt); see my comment below.

Also, I completely agree with Rory's comment: ISO-8601 dates are preferred over this old format - so this format generally shouldn't be used for new development.

For ISO-8601 formatted JSON dates, just pass the string into the Date constructor:

var date = new Date(jsonDate); //no ugly parsing needed; full timezone support

Finally figured it out.

The app code is correct as posted. The problem is with the configuration. The correct web.config is:

<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.0" />
    </system.web>
    <system.webServer>
        <handlers>
            <add name="ScriptHandlerFactory"
                 verb="*" path="*.asmx"
                 type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                 resourceType="Unspecified" />
        </handlers>
    </system.webServer>
</configuration>

According to the docs, registering the handler should be unnecessary from .NET 4 upwards as it has been moved to the machine.config. For whatever reason, this isn't working for me. But adding the registration to the web.config for my app resolved the problem.

A lot of the articles on this problem instruct to add the handler to the <system.web> section. This does NOT work and causes a whole load of other problems. I tried adding the handler to both sections and this generates a set of other migration errors which completely misdirected my troubleshooting.

In case it helps anyone else, if I had ther same problem again, here is the checklist I would review:

Did you specify type: "POST" in the ajax request?
Did you specify contentType: "application/json; charset=utf-8" in the ajax request?
Did you specify dataType: "json"in the ajax request?
Does your .asmx web service include the [ScriptService] attribute?
Does your web method include the [ScriptMethod(ResponseFormat = ResponseFormat.Json)] attribute? (My code works even without this attribute, but a lot of articles say that it is required)
Have you added the ScriptHandlerFactory to the web.config file in <system.webServer><handlers>?
Have you removed all handlers from the the web.config file in in <system.web><httpHandlers>?

Hope this helps anyone with the same problem. and thanks to posters for suggestions.
