simple json post url api

Posted By:      Posted Date: August 23, 2010    Points: 0   Category :ASP.Net


I am a json newbie :)

I have this site that has an api that can provide city name if I send my zip code as a parameter. 


the result is returned as a json object. Now i just want to read the result in my js function.

I have tried the following but it always returns null:

function postnr() {
    var url = 'http://www.postnummersok.se/api?q=16447';

Simple JSON request



I'm trying to make API calls to a service provider. I've never tackled JSON requests before but I want to give it a go - as they seem less verbose than XML. Could someone be kind enough to give me a simple example here? 

My confusion stems from some libraries I've come across. Do I need to add any libraries to my project? Or is it just a matter of creating a string that complies with JSON syntax and send it via a WebRequest?

How WCF 4 REST Service Support Form Post As Well As XML and JSON?


Using the rest 4 template.  I have a POST method defined, with an object as a parameter.  REST 4 does a great job of automatically mapping both xml and json posts to the method.  I tested this using an HttpClient test application to build and post xml content and then json content. 

I want to also support a standard form post to the method but am having problems!  

I'd like the same method already accepting and converting both xml and json to also work correctly for a form post.  I am testing this by creating an HttpUrlEncoded form in the test client, adding form name/value pairs that match what the method is expecting, and trying to post it.

However I get a 400 Bad Request.  Here's some example code that is returning a 400 bad request:

            var client = new HttpClient();

            HttpUrlEncodedForm form = new HttpUrlEncodedForm();
            form.Add("Id", "99");
            form.Add("Message", "Message test with 'special' chars #!#");
            form.Add("IpAddress", "");

            var response = client.Post("<valid-uri-here>", form.CreateHttpContent());


wcf 4 rest service accepts xml and json posts but get 400 bad request on form post


Using the rest 4 template.  I have a POST method defined, with an object as a parameter.  REST 4 does a great job of automatically mapping both xml and json posts to the method.  I tested this using an HttpClient test application to build and post xml content and then json content.  All data gets correctly mapped to the corresponding properties in my entity. 

I want to also support a standard form post to the method but am having problems! 

I'd like the same method already accepting and converting both xml and json to also work correctly for a form post.  I figured it would "just work" but no.

However I get a 400 Bad Request.  Here's some example code that is returning a 400 bad request:

Really straightforward but fails.  Ideas why? 


      var client = new HttpClient();

      HttpUrlEncodedForm form = new HttpUrlEncodedForm();
      form.Add("Id", "99"<

Post JSON data to WCF RESTful Service using jQuery

The POST request method is basically designed to post data to a web server for storage. That's why its normally used when submitting a complete form. In this WCF RESTful service tutorial, I'll try to explain how we can post JSON data to a WCF RESTful service using jQuery Ajax call with POST type. We discussed about "POST" HTTP verb in previous WCF tutorials but we didn't use it in our implementation. Purpose of this article is to understand "POST" request with complete implementation for a specific operation.

Creating a Simple Class in C#

The second article in the C# Object-Oriented Programming tutorial describes how classes are created in C# and how behaviour, in the form of publicly visible and private, hidden methods can be added. This demonstrates some of the uses of encapsulation

A Simple and Extensible Radio Button Style GridView

The GridView is one of the significant controls in ASP.NET 2.0 and later versions. No doubt it reduces a lot of work time. However, customizing the GridView control is not an easy task. For example, it's hard to add a radio button column to the GridView. This article demonstrates the reason why a radio button column cannot act as normal and how to create a simple and extensible radio button GridView.

Silverlight Simple Animation

Silverlight has several built in techniques for animating controls. Many of these technologies are particularly useful for creating simple animations meant to decorate a web page with eye catching movement that draws the reader's attention. In this post I will skip over these decorative technologies, and instead show how to create a simple animation using a technique similar to those used in many games.

Post back puzzle


Hi, I have a website where the user makes a selection from a combo box and it then fills a couple text boxes with text based upon the selection. I'm sure as you know it could take a second for the text to appear in the text box due to the post back. I know there is no way to make it instantanious, so what I would like to do it fill the text box with somthing like "Loading Info..." so the user does not type in it while the information is loading.

If you would like to see what I mean please go to this page: www.epiclinks.com/create.aspx and mess around with the combo boxes and You'll see what I mean.

What I would like to do is have it do a post back to write "Loading Info..." and then do another post back to fill it in based upon their selection. How would I do this?

I'm up for anything, so if you have a better solution than that please let me know.


I thought this would be simple... Trying to create a login does an ajax check before submit


I have the standard .net login control that is working.  (Still learning .net after 15yrs of classic)

What I want to do is OnButtonClick run a javascript function (to do an ajax call to the db to check if login is valid or not) and if it returns true, then submit the form normally, else don't submit. The piece that I can't figure out, is how to correctly override the default click even to hit my JS routine and then submit the form properly afterwards.

Thanks ahead of time

HTTP Post and WebService


I am working on a application which will accept the data in the post request. My application also wants to expose a web service and want to call another web service. Considering all these 3 action that I want to do, can I create a single application which will have a web form which will accept the POST request and expose a web service at the same time.

Although it may be possible to achieve this, Is this a correct way of doing it?

server side does not save data when using POST data to another URL using WebRequest


 I am using a IIS 7.5 on Windows 7. I have a simple application that uses System.Net.WebRequest to POST data to another URL (in fact, the server side URL is on my local computer and it is hosted in IIS 7.5).

  1.  The problem is the server does not save data from client although on the client side codes when I debug and I see the OK message return from the code line

   response.StatusDescription; // this has value of "OK"
2. How can I debug the server code side where to receive the request from client side who posts the data ?

The following is the codes for client who posts data using System.Net.WebRequest, and codes for server side who received posted data to save to database.

Client side codes: // also run on my local computer

public string PostIntegrationXml(XmlDocument xmlSubmitDoc)
