Network

Edit

Note: This plugin was removed in MvvmCross 7.1.0

The purpose of the Network plugin is to provide an implementation IMvxReachability. It is currently implemented for iOS, Android, UWP and WPF.

public interface IMvxReachability
{
    bool IsHostReachable(string host);
}

Since this original purpose, Network has now further been expanded to provide a simple Rest implementation - and this is available on Android, iOS, Windows UWP and WPF.

The Rest client is mainly implemented using the IMvxRestClient and IMvxJsonRestClient interfaces

public interface IMvxRestClient
{
    void ClearSetting(string key);
    void SetSetting(string key, object value);

    void MakeRequest(MvxRestRequest restRequest, Action<MvxRestResponse> successAction,
                     Action<Exception> errorAction);

    void MakeRequest(MvxRestRequest restRequest, Action<MvxStreamRestResponse> successAction,
                     Action<Exception> errorAction);
}

public interface IMvxJsonRestClient
{
    Func<IMvxJsonConverter> JsonConverterProvider {
        get;
        set;
    }

    void MakeRequestFor<T>(MvxRestRequest restRequest, Action<MvxDecodedRestResponse<T>> successAction,
                           Action<Exception> errorAction);
}

These are supported by a small set of Request and Response classes:

• MvxRestRequest, MvxStreamRestRequest, MvxJsonRestRequest, MvxStringRestRequest, MvxStringRestRequest, MvxMultiPartFormRestRequest and MvxWwwFormRequest
• MvxRestResponse, MvxStreamRestResponse, MvxJsonRestResponse

To make a simple fixed url Rest request, you can use:

var request = new MvxRestRequest("http://myService.org/things/list");
var client = Mvx.IoCProvider.Resolve<IMvxRestClient>();
client.MakeRequest(request,
(MvxStreamRestResponse response) => {
    // do something with the response.StatusCode and response.Stream
},
error => {
    // do something with the error
});

To use the Json APIs, you must have an IMvxJsonConverter implementation available - one way to get this is to load the Json plugin. With this in place, a simple Json upload with Json response might look like:

var request = new MvxJsonRestRequest<Person>("http://myService.org/things/add")
{
    Body = person
};

var client = Mvx.IoCProvider.Resolve<IMvxJsonRestClient>();
client.MakeRequestFor<PersonAddResult>(request,
(MvxDecodedRestResponse<PersonAddResult> response) => {
    // do something with the response.StatusCode and response.Result
},
error => {
    // do something with the error
});

Note:

• This Rest module is a ‘light-weight’ implementation which works for many simple Rest web services.
• For more advanced web service requirements, consider extending the classes offered here or consider importing other more established Rest libraries such as RestSharp (http://restsharp.org/).
