上游消息- iOS GCM



我试图实现谷歌消息在我的应用程序和服务器使用Xamarin API。下游消息(服务器到应用程序)工作得很好,但我不能让上游工作。

在服务器端,我使用PHP与XMPP库(JAXL),这样我就可以在GCM服务器上验证并向设备发送消息。我已经注册接收代码:

$XMPPClient->add_cb("on__message", function($stanza){ 
        echo "new message";
        $data = json_decode(html_entity_decode($stanza->childrens[0] -> text), true);
        $messageType = $data['message_type'];
        $messageId = $data['message_id']; //message id which was sent by us
        $gcmKey = $data['from']; //gcm key;
        ...
        });

在客户端,我使用GCM api调用SendMessage:

    public class SendClass : ReceiverDelegate
{
    public void SendMessage(string Message)
    {
        InstanceId.SharedInstance.Start(Google.InstanceID.Config.DefaultConfig);
        Service.SharedInstance.SendMessage(new NSDictionary("key", "value"), @"SenderID@gcm.googleapis.com", "Message");
    }
    public override void DidSendDataMessage(string messageID)
    {
        base.DidSendDataMessage(messageID);
    }
    public override void WillSendDataMessage(string messageID, NSError error)
    {
        base.WillSendDataMessage(messageID, error);
    }
}

GCM API有两个方法应该在消息发送到服务器的过程中调用,DidSendDataMessageWillSendDataMessage,但是这些方法没有被调用。

谁能给我一些提示吗?

谢谢!

我发现问题了。首先,您需要设置 googlemessaging的de delegate。配置到你的类(继承自ReceiverDelegate),注意不要从GoogleInstanceID.Config.

之后,您需要从两个库中调用Start()方法,GoogleMessaging。Service and Google.InstanceID。然后魔术就完成了:
        private void StartService()
    {
        NSError ConfigError;
        Google.Core.Context.SharedInstance.Configure(out ConfigError);
        GCMSenderID = Google.Core.Context.SharedInstance.Configuration.GcmSenderID;
        SendC = new SendClass();
        Google.GoogleCloudMessaging.Config Conf = Google.GoogleCloudMessaging.Config.DefaultConfig;
        Conf.ReceiverDelegate = SendC;
        Service.SharedInstance.Start(Conf);
        Service.SharedInstance.Connect(delegate (NSError error)
        {
            if (error == null)
            {
                GetToken();
            }
        });
    }
    private void GetToken()
    {
        InstanceId.SharedInstance.Start(Google.InstanceID.Config.DefaultConfig);
        InstanceId.SharedInstance.Token(GCMSenderID, Constants.ScopeGCM, new NSDictionary(Constants.RegisterAPNSOption, DevToken,
            Constants.APNSServerTypeSandboxOption, 1), delegate (string Token, NSError error)
            {
                if (Token != null)
                {
                    OnTokenReceived(Token);
                }
            });
    }
