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:
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();
As it is now I create a JavaScript object and then stringify it, put it in a hidden textbox and my code behind can read this string. I then use JSON.NET to parse the string which works fine. I now try to use ajax to post it to my web service but have some issues with how to send the string. I have tried many ways but gets the common errors like
Invalid JSON primitive: myString.
So I checked this out [URL] and it works with hard coded values but I want to use a variable.
JavaScsript to create the object:
for (var i = 0; i < results.rows.length; i++) { var row = results.rows.item(i); var customer = new Object(); customer.id = row['id'] customer.name = row['name'] var customerString = JSON.stringify(customer); $.ajax({ type: "POST", url: "synchronise.asmx/synchroniseCustomers", data: "synchroniseCustomers: " + customerString, contentType: "application/json; charset=utf-8", dataType: "json", error: function (xhr, status) { alert("An error occurred: " + status); }, success: function (msg) { alert("success"); } }); }
WebMethod:
public void synchroniseCustomers(string customerString) { JObject o = JObject.Parse(customerString); string id = (string)o["id"]; string name = (string)o["name"];
If I use data: '{ FirstName: "Dave", LastName: "Ward" }'
in the example above it works but I wish to pass on a string instead.
I want to make a web servcie(.svc) that returns JSON data after entering the input.....which is resulted as in the downloaded filein JSON format.i want something like that-http://209.62.6.226/GracoRest/service.svc/Rest/WheretoBuyplease help me for the above but....step by step...i m trying WCF very 1st time
I just hit the following issue: I am calling a web service that returns a serialized JSON object let's say: __type, FirstName, LastName (.net object Person with properties FirstName and LastName). __type's value is Test.Person
I have created a JS object using Type.registerNameSpace/registerClass called Demo.Person and it is registered on the page using the ScriptManager. Everything is working fine; I am able to get data from the server on the call back.
Is it possible to make the returned object from the web service be an instance of the declared JavaScript Demo.Person class? The idea would be to call a method like result.getFullName() on the client side without having to copy all the properties. This is just a simple scenario for more complex objects.
I am using ASP.Net 3.5. I have fiiled dropdown list in javascript using ajax service but unable to get its selected value in button click event on server side.
I'm not able to call a service using the scriptmanager and javascript. But when I include the service into the project i call it. but when i seperate it in another project. I'm not able to call.
i am running with an unfamilier issue with jquery ajax and wcf service . i have created a simple wcf service and trying to show it on a asp.net label... the wcf service just returns a string which has to b shown on a label. the url has been set on jquery ajax url to call the wcf service using rest. but somehow i am not getting the desired thing done . the ajax cannot retrieve the data from the wcf service , here are the code snippets.
The Ajax Portion in default.aspx :
[Code]....
The Service Contract for WCF :
[Code]....
The implemented Method :
[Code]....
and the Web.Config :
[Code]....
can someone figure out here i am going wrong .... that the ajax is unable to retrieve the data from the above wcf Service .. its just a very basic and simple one .. but unable to figure out the Real Prblem.
I am using asp.net 3.5. I filled dropdown list in javascript using ajax service but unable to get its selected value in button click event on server side.
My WCF Client calls my WCF Service which then calls ASMX Web Service. The problem is i have configured my wcf client and wcf service to windows credentials type but when wcf service calls asmx service the user credentials (default windowsidentity) is not passed to asmx service.
In WCF Service i am able to get user identity by using : Thread.CurrentPrincipal.Identity.Name; WCF Service - i have disabled anonymous access and enabled windows authentication. ASMX Web Service - i have disabled anonymous access and enabled windows authentication. WCF Service Config [Code]....
I have passed some JSON to my page via a webservice. I used JSON.NET to convert XML to JSON. The JSON output looks ok to me, but I am unable to access some of the items in the response. I am not sure why it is not working. I am using jQuery to read the response and make the webservice call. Even when I try to read the length of the array it says 'undefined'
function GetFeed(){ document.getElementById("marq").innerHTML = ''; $.ajax({ type: "POST",
We have a web application providing a service using a simple REST interface (GET/POST methods) and returning results in JSON format.
A client wants to use the service from an ASP application (I assume ASP.NET) and asks for example code.
Is there any standard/widely-acceptable procedure for consuming JSON based web services from an ASP.NET application? I'm not familiar with the .NET framework, but can work my way through C#.
I originally have the question posted here, but I need as many eyes as possible on it.Essentially, I'm having issues redirecting to an action in mvc2 when working with JSON data. I post a stringified JSON object to an action and the action in turn redirects as needed. It worked previously when using form fields, but not when I'm posting JSON. To get posted JSON objects to properly bind to parameters objects in MVC, I'm taking advantage of the JsonValueProviderFactory class from MVC2Futures/MVC3Beta.Why is this occuring? The jQuery ajax call is telling the server "I'm giving you json, I expect html in return" and all actions pointed to via RedirectToAction calls are structured in a similar manner. I instead get stuck in a loop, continually hitting the originally requested action, with a prompt to reenter authorization information to boot! It seems lose authentication/authorization information in the process.The linked question on
What are the pros and cons of the following 2 cases: Case I: Traditional way: Add service reference in project. Create object and Get data from service on server side and bind to asp.net grid. Case II: Update Service for JSON behavior. Add service reference in project. Call service from javascript to get data. Bind data to jquery grid. Which one is the best approach and why?(Not developer point of view)
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.
I have an containing a list of divs that jQuery turns into progress bars. On .ready, I build a list of all of these progress bars and for each one, call a webservice that gets a value indicating how full the progress bar should be. In order to do this, I need to pass the ID of the div to the web service.
Because the divs are inside a ListView, I manually set the id to be id="completionbar_<%# Eval("MilestoneID") %>"
However, when I pass this id into my web service, it comes up as "undefined" every time. When I view the source, it looks like it's set correctly.
I still can't seem to get this to work.I've tried string arrays object arrays dictionaries. I might be formatting my JSON incorrectly however I am using the labs_JSON plugin. If I remove my data and test the webservice it calls correctly. The : My code looks as follows :
After much head scratching as to why my returned Json string is breaking JSON.parse, I have realized that it is the returned dates that it doesn't like.
