AngularJS $http get to ASP.NET Web Api with object in parameters

Question

I'm trying to get filtered data from server using a filtering object I pass to the server side. I have managed to get this working with a post:

angular:

var filter: { includeDeleted: true, foo: bar };
$http({ method: 'post', url: 'api/stuff', data: filter });

web api:

public IEnumerable<StuffResponse> Post([FromBody]Filter filter)
{
    return GetData(filter);
}

But i don't want to use a post for this, I want to use a get. But this does not work:

angular

$http({ method: 'get', url: 'api/stuff', params: filter });

web api

public IEnumerable<StuffResponse> Get([FromUri]Filter filter)
{
    return GetData(filter);
}

Also tried specifying params: { filter: filter }. If i try [FromBody] or nothing, filter is null. With the FromUri i get an object at least - but with no data. Any ideas how to solve this, without creating input parameters for all filter properties?

Solution 1

A HTTP GET request can't contain data to be posted to the server. What you want is to a a query string to the request. Fortunately angular.http provides an option for it params.

See : http://docs.angularjs.org/api/ng/service/$http#get

Solution 2

Yes you can send data with Get method by sending them with params option

var data ={
  property1:value1,
  property2:value2,
  property3:value3
};

$http({ method: 'GET', url: 'api/controller/method', params: data });

and you will receive this by using [FromUri] in your api controller method

public IEnumerable<StuffResponse> Get([FromUri]Filter filter)
{
    return GetData(filter);
}

and the request url will be like this

http://localhost/api/controller/method?property1=value1&property2=value2&property3=value3

Solution 3

Solved it this way:

Angular:

$http({
       url: '/myApiUrl',
       method: 'GET',
       params: { param1: angular.toJson(myComplexObject, false) }
      })

C#:

[HttpGet]
public string Get(string param1)
{
     Type1 obj = new JavaScriptSerializer().Deserialize<Type1>(param1);
     ...
}

As you see in the example with 'get', I am using 'params'. And I can see the filter object is translated to URL parameters in the request - but the server can't deserialize it to the Filter object

Filter is a class name, So you can't do this, you can't pass class in a query string, so you need to change the class to string,int,float...

Vil's answer provides a cleaner solution imo

that's a POST. Does it work with a get? Plus it's not angular JS.
