I am working in MVC 4 and using angularJs for client side scripting.I made an edit method which posts Id of the object to the MVC controller.When i click on edit . The url it generates is http://localhost:59568/NewsLetter/GetNewsLetterDataAng?id=%2256d6ac05afb241256469194b%22
but it should be
http://localhost:59568/NewsLetter/GetNewsLetterDataAng?id=56d6ac05afb241256469194b
Because of extra %22 in the front and end it is throwing 500 error.
Please suggest me how to remove it from the url
To complete the comment above I'll let you know an other thing about how to send and get data using angular js.
If you want to pass a json object to the server it's better to do it in a POST using the $http service builtin angular like in the example below:
$http.post(url, jsonObject){...};
By doing so, you send the json object as the body of the request and in asp.net-mvc the model binder can bind that json object to a class in your C# code.
In your case there is no need, as I said in the comments, for the JSON.stringfy method call when doing a GET request.

I have created a webpage using ReactJS. When I called my web URL in postman using the GET method, I got my HTML page as a response. But when I changed this method to POST, then got an error(404 Not Found). Can I make my URL available in the POST method too? Is this possible?
i had been working in a Spring Rest Data API in an application (just for fun).
I have the core made, works fine but now I want to use AngularJS as front-end.
I had work with Jackson (Mapping Java Objects to JSON), but with Spring Rest Data the Json response it's diferent, it has _embedded, _links, self, etc. links that make me confuse. I have something like this in the root url http://localhost/8080/app/api/tarifas
I have used a JS script called restangular but i have serveral problems (I'm newbie with Angular)
In my controller i have this
Check the error
If I add a RestangularProvider in my app.config(...) and change the Controller to getList instead get, works fine, but I need several entities data formats.
Any help it's welcome. If you know a better way please tell me.
Thanks!!
UPDATE
I found a form to do this (i don´t know if it's the better) but now my problem is the next:
I have objects that has other objects as attributes (realtionship), and the reference in the JSON is a link (not an object). Then, in the grid; the value of the description's internal object is blank. To get the json data I found this
Now I have the next content for one register (one of the grid)
And my grid (In Angular, HTML) looks like this (empty fields)
How can I retrieve the attribute description from the member estado, categoria, etc. and show it in the grid. Should make the request to get it?
Thanks!!
You can use either angular.toJson or json.stringify

I'm new to AngularJS and client side stuff and I'm adding a new page to an old application that uses Struts 1.3 as its framework. I would like to use AngularJS for the front end.
I know how to return JSON from the action class by writing the JSON to the front end and returning null for the action forward. However, I'm unclear how I would populate the scope variables within the controller after the GET. If I use a GET in the controller and get JSON back, how does my ActionForm fit into all this? Is it useful at all? Can I have a GET and POST for the same controller if I want to send new values back to my action? And, can I have variables like:
$scope.items={}
$scope.items.name=""
$scope.items.email=""
And then just send json.stringify(items) as my data in the POST if I can't use the form somehow?
I haven't found much information using AngularJS with Struts 1.3 so far.
EDIT:
I'll try to answer as best as possible what conclusion I came to but my questions above were very vague since I didn't really know what I was talking about and my position with the company I worked for has ended so I no longer have access to that code. What I meant to ask earlier was what am I going to do with the action form that I usually use for Struts actions and how am I going to get data from the front end to my action class during a POST. I found out that my usual ActionfForm was useless for what I wanted to do so I got rid of it and wrote a JSON object during the GET that would be modified on the frontend and passed back to another action when I did the POST. This is done like a normal POST to whateverAction.do, but I had to configure the data I was sending in the POST and name it something. I then picked up the modified JSON object by using
request.getParameter("jsonObjName")
and parsed it to different LinkedHashMap objects for each object in the JSON object. I think you can use the JSONObject classes instead of LinkedHashMap to parse if you are using JavaEE but I was using SE so I didn't have access to those in this project. Here a link to another page I used for the POST configurations:
How to get the data in Struts from AngularJS post
On the Java side you can also try to use Gson library that allows you to parse string to and from JSON, but Struts 1 generally won't fit well with AngularJS, if you remove the form on Java side, than makes no sense to keep Struts 1.
And if no possibility to remove Struts 1, than just keep Struts 1 for existing functionality and start using Struts 2 for new screens where AngularJS is applied.
It will be much easier cause the JSON from AngularJS' POST will automatically be bound to the bean object that has to match to JSON properties format and name.
I'm trying to use angular and asp.net vNext Web API. I have a controller up but when using angular's $resource the object values are not resolved (Post method parameter is null)
The request itself has nothing out of the ordinary, though it does send json back. I think I've seen somewhere that vNext doesn't support content negotiation yet so maybe that's it. Can anyone confirm or shed some light on the subject?
Also - is there a way to get to the raw post data in Web API? (I'm using the core framework) cause the Request.Form that I know from mvc is not there any more. I tried the GetFormAsync but that returns an empty collection.
EDIT:
Confirmed that the reason for not binding the parameter is the fact that data is sent as JSON. When form encoding is used, the parameter values are resolved correctly.
using [FromBody] attribute on the param solved the issue.
I'm using AngularJS $resource service.
After creating an instance of the resource, I'm trying to change one of the GET params.
The problem is that i keep getting the original value.
any ideas?

Iliya
