是否可以使用 Firebase 的 FCM 向 iOS 设备发送 apns 推送通知？
所需工作流程：
iOS 应用程序向我的 .NET 服务器发送请求，以向其提供推送令牌。我的 .NET 服务器将处理所有推送通知。所以我假设这将是对火基地的 http 请求，火基地会发出通知吗？
这个工作流程可行吗？
我使用Firebase的FCM使用Android应用程序，所以我认为一定有办法使用iOS。
下面是在 C# 中使用 FCM 发送推送通知的代码片段。
NotifBooking objnotif = new NotifBooking();
string ApplicationID = "AIzaSyCBM20ZXXXXXXXXXXjog3Abv88";
string SENDER_ID = "962XXXXXXX";
var value = "Alert :" + Message + ""; //message text box
WebRequest tRequest;
tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send"); tRequest.Method = "post";
tRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
tRequest.Headers.Add(string.Format("Authorization: key={0}", ApplicationID)); tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
tRequest.ContentType = "application/json";
var data1 = new
{
to = "" + dt.Rows[i]["RegId"].ToString().Trim() + "",//Device RegID
priority = "high",
notification = new
{
body = Message,
title = Heading,
is_background = true,
image = "abc.com/images/1_icon.png",
appicon = "abc.com/images/1_icon.png",
sound = "default"
},
data = new
{
//body = Message,
//is_background=false,
//title = "Test FCM",
//appicon = "myicon",
image = "abc.com/images/1_icon.png"
},
};
Console.WriteLine(data1);
var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(data1);
Byte[] byteArray = Encoding.UTF8.GetBytes(json);
tRequest.ContentLength = byteArray.Length;
using (Stream dataStream = tRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse tResponse = tRequest.GetResponse())
{
using (Stream dataStreamResponse = tResponse.GetResponseStream())
{
using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String sResponseFromServer = tReader.ReadToEnd();
string str = sResponseFromServer;
}
}
}
}
objnotif.data = json;
}
您应该从 Firebase 获取设备令牌，并使用相同的令牌在后端注册当前用户。
之后，您可以从后端发送推送通知。
将此代码放在 AppDelegate 类中。
从 DoneLaunching 调用 InitAPNS((。
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
//TODO: save token and register one in backend side
Settings.DeviceTokenFCM = InstanceId.SharedInstance.Token;
}
public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, Action<UIBackgroundFetchResult> completionHandler)
{
ShowPushMessage(userInfo);
}
private void ShowPushMessage(NSDictionary userInfo)
{
if (userInfo != null)
{
try
{
var apsDictionary = userInfo["aps"] as NSDictionary;
var alertDictionary = apsDictionary?["alert"] as NSDictionary;
var body = alertDictionary?["body"].ToString();
var title = alertDictionary?["title"].ToString();
var window = UIApplication.SharedApplication.KeyWindow;
var vc = window.RootViewController;
var alert = UIAlertController.Create(title, body, UIAlertControllerStyle.Alert);
alert.AddAction(UIAlertAction.Create("OK", UIAlertActionStyle.Cancel, null));
vc.PresentViewController(alert, animated: true, completionHandler: null);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
}
}
private void InitAPNS()
{
// Monitor token generation
InstanceId.Notifications.ObserveTokenRefresh(TokenRefreshNotification);
if (UIDevice.CurrentDevice.CheckSystemVersion(10, 0))
{
UNUserNotificationCenter.Current.RequestAuthorization(UNAuthorizationOptions.Alert | UNAuthorizationOptions.Sound | UNAuthorizationOptions.Sound, (granted, error) =>
{
if (granted)
{
InvokeOnMainThread(UIApplication.SharedApplication.RegisterForRemoteNotifications);
}
});
}
else if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
{
var pushSettings = UIUserNotificationSettings.GetSettingsForTypes(
UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound,
new NSSet());
UIApplication.SharedApplication.RegisterUserNotificationSettings(pushSettings);
UIApplication.SharedApplication.RegisterForRemoteNotifications();
}
else
{
UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;
UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);
}
Firebase.Core.App.Configure();
}
private void TokenRefreshNotification(object sender, NSNotificationEventArgs e)
{
ConnectToFCM();
}
private void ConnectToFCM()
{
var tokenFirebase = InstanceId.SharedInstance.Token;
////registation token in background thread
System.Threading.Tasks.Task.Run(() =>
{
if (!string.IsNullOrEmpty(tokenFirebase))
{
Firebase.CloudMessaging.Messaging.SharedInstance.SetApnsToken(tokenFirebase, ApnsTokenType.Production);
}
});
Messaging.SharedInstance.ShouldEstablishDirectChannel = true;
