Send JSON request with Restkit RKParams

问题

I need to send a JSON request to a REST service. I'm using Restkit RKParams to send a request.

Currently it works as follows:

[params setValue:@"-46.566393" forParam:@"checkin[lng]"]; 
[params setValue:@"-23.541576" forParam:@"checkin[lat]"];

Send:

{
    "checkin":
    {
        "lng":"-26.566393",
        "lat":"-63.541576"
    }
}

Now I want to form JSON data like this (with few more items):

{
    "checkin":
    {
        "lng":"-26.566393",
        "lat":"-63.541576",
        "votes":
        [
            {"vote_id":28},
            {"vote_id":11}
        ]
    }
}

How would I set the params to work as desired? It is possible to do this?

回答1:

RestKit does handle nested models, but it looks like it doesn't do that directly in RKParams. I would look at some of the other classes to do what you're trying to do. Key-value mapping looks like it will do what you want.

Or if you want to hack it,

[RKParams setValue:@"[{\"vote_id\":28},{\"vote_id\":11}]" forParam:@"checkin[votes]"]

might just work. No promises, though.
