I'd like to read data server-side from a web service that outputs in json format. I haven't found any good examples that don't use jquery and are server-side.
Specifically I'm looking at the "weight" field from this api:

Just ramping up on JSON and JQuery and returning data to a ASP.NET web page from a web service using Ajax. The JQuery part is pretty straight-forward. However, when trying to return JSON formatted data instead of XML from a 2.0 web service, I'm stuck. The web service does have the System.Web.Script.Services.ScriptService attribute, so I can hit it via JavaScript; however, the web service always...always...returns data in XML format, no matter if I explicitly say I want JSON as the datatype in my JQuery code. So I don't know if this is an issue with the web service or the JQuery code. I posted this here, but realize that the category could be incorrect depending on where the issue is. Is there no way to return JSON data from a 2.0 web service? It's a production web service, so I can't change the code unfortunately.
View 3 RepliesI Need by service contract to return the xml/json result depending on the request type. function which will convert my result set (i am using linq to sql) so that i do not need to create the xml format for the result set by iterating through the table row many times.What is the suitable way to do that.
I need a kind of short cut method which will convert the table data to xml result.Had i been using asp.net mvc i would have been able to generate the xml data by overriding the the ExecuteResult method in the ActionResult and giving Conetnt-Type = "text/xml" as OP.But since i am using Wcf i don't have the controller context(as controller context is the parameter that needs to be passed to Execute Result).
My present code for converting the table data to the xml format is below.
public XDocument UsersLists(string authToken)
{
bool IsAuthenticated = Authenticate(authToken);
XDocument xDoc = new XDocument();
XElement root = new XElement("Users");
[Code]....
I need to eliminate this way of generating xml for each table records.

I am using JQuery & JSON (POST) to call webmethod. However I can call only webmethod located at aspx file but not in asmx file Below are sample codes
CustomValidate.asmx
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Public Class CustomValidate
Inherits System.Web.Services.WebService
'ACCESS VIA JSON
<System.Web.Services.WebMethod()> _
Public Shared Function AJAX_Test(ByVal date1) As Boolean...
Return True
End Function
End Class
Javascript: JQuery JSON
function isDates(source, arguments) {
var isValidDate;
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CustomValidate.asmx/AJAX_Test",
data: '{date1: "' + arguments.Value + '"}',
dataType: "json",
async: false,
success: function(result) {
isValidDate = result;
},
error: function(httpRequest, textStatus, errorThrown) {
alert("status=" + textStatus + ",error=" + errorThrown);
}
});
arguments.IsValid = isValidDate;
}
It always return javascript undefined error. But if I put the AJAX_Test webmethod in aspx page and replace the url: "CustomValidate.asmx/AJAX_Test" to "mypage.aspx/AJAX_Test". It works fine.
I am new to WCF, I was using web service asmx before. I have trouble on making my wcf JSON ajax service work through http like asmx.Could you help me see what wrong in my code?My WCF services are defined in my website application folder. My aim is to call this service in my aspx page java-script code and return complex object back as JSON to my javascript. I have no problem on doing this through classic asmx web service.
When I try to test it through my browser by type this in the URL , URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc/GetAll. it return "Method not allowed."
But if I type just this URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc, it return this:
WCFCompanyService Service
You have created a service.To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:
svcutil.exe URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc?wsdl
This will generate a configuration file and a code file that contains the client class. Add the two files to your client application and use the generated client class to call the Service. For example:
C#
class Test { static void Main() { HelloClient client = new HelloClient();
[Code]....
This is my Ajax-enabled WCF service code:
[Code]....
This is the web.config service model setting

I have a text file named gisQuery129.json that is created using Json.NET - [URL] There is an example on how to create a JSON file and I have done that successfully, but I want to read the file on a page load event and add the values to .NET textbox controls for input values in a query. The created file looks like the following:
{
"myData": {
"randomNumber": "129",
"Application": "MyMapApp",
"FeatureId": "ALL",
"Feature": "ALL",
"spatialQuery": "FEATURE_ID= '11111' AND REQ_SEQ_NUM= 1 AND RAND_PARAM= 129 OR FEATURE_ID= '22222' AND REQ_SEQ_NUM= 2 AND RAND_PARAM= 129"
}
}
I want to read the data in the above sample JSON data and then populate my textboxes something like this:
txtRandParam.text = "129"
txtApplication.text = "MyMapApp" and three more text boxes after that.

I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable.
EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.
i built contact form in aspx 3.5 and i'm using jquery to send it to web service (asmx).the web service need to return success or error code. the problem is that at the web method i get only single value and not array. I'm kind of new in ajax and i tried a lot of solutions but without any results.. please if you can only explain me the principle of what to do it also be good..this is the client side:
$(document).ready(function()
{
$("#submit").click(function(event)
{
[code].....
when i debug i see that the input parameter "name" contains only one string - i dont know how to get the full json string that i send to the service and contains all the form data - i want to desirialize it to string array or something like, and process it.
We have an exisiting Web Service which receives SOAP requests and returns the data accordingly. However, we have a new project which requires the same information but the Android SDK doesn't support SOAP so we need to use JSON. As JSON is just a data container format, I need to write a new module to replace the SOAP WSDL which receives a querystring from the Android app and then processes the data and returns it in a JSON packet. The problem is that having never used JSON I'm unsure as to how I return the data to the app in JSON format. Does anyone have any examples I can look at in VB.Net or C#?

How can it be sent.???
One way is to Send it as XML Document But I don't know how to do this i.e. How to convert this set of record in to XML Document. and then How to retrieve values from this Document in a GridView at the requesting side.
I am getting this JSON string from an ASP.Net webservice:
{"d":{"Table":[{"col1":123,"col2":"name","col3":"name","col4":100,"col5":"/Date(1153033200000)/"},{"col1":123,"col2":"name","col3":"name","col4":101,"col5":"/Date(1153033200000)/"},{"col1":123,"col2":"name","col3":"name","col4":102,"col5":"/Date(1153033200000)/"}]}}
In my jQuery how do I reference the Table code so I can loop through the data?
msg.d[i].col1
What am I missing? msg.d.table[i]?
I have read about desearlizing a json file into class fields which I understand. But what I cannot find in a tutorial is how to read in the json data. Everyone just adds the data to a variable and uses it. I will be passing in a json file from a mobile app. I know I should use a web service but for now I want to use an asp.net ASPX page to do this. I will be using the newtonking json control.
View 1 RepliesI´m new to web services and currently working with an integration to a third party system. I have created a web service that creates and exports a <List> of objects. The challange I have is that the third party company consuming my created web service wants to have the data as a XML document just as it is presented when I push the "Invoke button" when testing my web service on the server it resides on. Doing so I get all my exported data presented as a nice XML document. Since a web service actually exports this XML it should be a fairly simple task, but I do not know how? Would perhaps anyone have a code snippet consuming a web service and present the data just as an XML document? Or could point me to an example? I´m using VS 2008.

View 2 RepliesA customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
I have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
