Passing an object as parameter to Breeze controller action

Question

I'm trying to send an object as a parameter through Breeze without success. Using the following code I can send a primitive type: Client: ``` var query = EntityQuery .from('account/authenticate') .withParameters({ loginRequest: "hello" }); ``` Server: ``` [BreezeController] public class AccountController : ApiController { [HttpGet] public LoginResult Authenticate(string loginRequest) { // String for loginRequest received successfully } } ``` However, if I try and pass a complex type up, the param is always null: Client: ``` var loginRequest = { userName: 'me', password: 'pass' }; var query = EntityQuery .from('account/authenticate') .withParameters({ loginRequest: loginRequest }); ``` Server: ``` [BreezeController] public class AccountController : ApiController { [HttpGet] public LoginResult Authenticate(LoginRequest loginRequest) { // Object for loginRequest always null } } ``` I believe this is in part because Breeze always uses a GET for queries. A POST might handle the serializati…

Accepted Answer

You may be missing a [FromUri] attribute. Any time I tried to pass a more complex object or set of parameters everything would come back as null until I added that attribute.

```
[BreezeController]
public class AccountController : ApiController
{
    [HttpGet]
    public LoginResult Authenticate([FromUri] LoginRequest loginRequest)
    {
        // Object for loginRequest always null
    }
}
```
