PushSharp是一个C#编写的服务端类库,用于推送消息到各种客户端,支持iOS(iPhone/iPad)、Android、Windows Phone、Windows 8、Amazo、Blackberry等设备。
官方网站:https://github.com/Redth/PushSharp
当前最新稳定版本为2.0.4,支持通过NuGet获取(https://www.nuget.org/packages/PushSharp/)
提供了易于使用的API,支持以下平台的消息推送:
100%的托管代码完全兼容Mono平台。
PushSharp主要包含以下程序集:
其中,PushSharp.Core为必须的组件,其他的可以根据自己需要来选择对应平台。
平常使用只需要用NuGet来获取程序集即可:
Install-Package PushSharp
这样会把主流平台的程序集(Apple/Android/Windows/WindowsPhone)都下载下来,可以根据自己需要删除用不到的平台组件。
假如需要使用Blackberry等NuGet包里没有的组件,则需要到官方网站(https://github.com/Redth/PushSharp)获取源码自行编译。
对于Apple平台,只需要PushSharp.Core和PushSharp.Apple组件即可。
官方WIKI提供了详细的证书配置步骤:
Apple平台证书创建流程:
对于Apple平台需要特别说明:
启用消息推送都是在AppDelegate里注册来完成的。
对于使用objc语言编写的客户端:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if (application.enabledRemoteNotificationTypes == UIRemoteNotificationTypeNone) { [application registerForRemoteNotificationTypes: UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound]; } application.applicationIconBadgeNumber = -1; // Override point for customization after application launch. return YES; } - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { NSString *pushToken = [[[[deviceToken description] stringByReplacingOccurrencesOfString:@"<"withString:@""] stringByReplacingOccurrencesOfString:@">" withString:@""] stringByReplacingOccurrencesOfString: @" " withString: @""]; [[NSUserDefaults standardUserDefaults] setObject:pushToken forKey:@"pushtoken"]; // 保存起来 }
对于使用MonoTouch的客户端:
public override bool FinishedLaunching(UIApplication app, NSDictionary options) { app.RegisterForRemoteNotificationTypes( UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound); app.ApplicationIconBadgeNumber = -1; // ... return true; } public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken) { // 成功接收到用于消息推送的token string tokenStr = token.Description; string pushToken = tokenStr.Replace("<", string.Empty).Replace(">", string.Empty).Replace(" ", string.Empty); NSUserDefaults.StandardUserDefaults.SetString(pushToken, "pushtoken"); } public override void FailedToRegisterForRemoteNotifications(UIApplication application, NSError error) { // 消息推送注册失败 } public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, Action<UIBackgroundFetchResult> completionHandler) { // 接收到推送的消息 // 在iOS7可能需要开启Background Modes的Remote Notifications }
在接收到deviceToken的时候先存储在NSUserDefaults中,在用户登录的时候再取出来一起发送到服务端:
NSString *pushToken = [[NSUserDefaults standardUserDefaults] stringForKey:@"pushtoken"]; //objc string pushToken = NSUserDefaults.StandardUserDefaults.StringForKey("pushtoken"); //MonoTouch
服务端在用户登录成功之后,把接收到用户的用户名与pushToken关联起来,在推送消息的时候就可以针对指定用户来推送,具体的过程略。
而对于不需要用户登录的app,可以在接收到deviceToken的时候直接发送到服务端。
更多的客户端配置参考PushSharp源码的Client.Samples及PushSharp.Client目录。
var pusher = new PushBroker(); pusher.RegisterAppleService(new ApplePushChannelSettings(File.ReadAllBytes("yourAppId.p12"), "证书的密码")); pusher.QueueNotification( new AppleNotification() .ForDeviceToken(pushToken) // 从数据库等地方获取设备的pushToken .WithAlert("测试iOS消息推送 - 囧月") .WithBadge(1) .WithSound("default") );
在RegisterAppleService方法中可以注册多个APNS证书,PushSharp可以自动检测是Development/Production,这时候需要为证书设置标识:
pusher.RegisterAppleService(new ApplePushChannelSettings(File.ReadAllBytes("yourAppId.p12"), "证书的密码"), "证书标识如youAppId_development"); pusher.RegisterAppleService(new ApplePushChannelSettings(File.ReadAllBytes("yourAppId.p12"), "证书的密码"), "证书标识如youAppId_production");
此外,可以注册各种事件来获得各种状态:
pusher.OnDeviceSubscriptionChanged += pusher_OnDeviceSubscriptionChanged; pusher.OnDeviceSubscriptionExpired += pusher_OnDeviceSubscriptionExpired; pusher.OnNotificationSent += pusher_OnNotificationSent; pusher.OnNotificationFailed += pusher_OnNotificationFailed; pusher.OnNotificationRequeue += pusher_OnNotificationRequeue; pusher.OnChannelCreated += pusher_OnChannelCreated; pusher.OnChannelDestroyed += pusher_OnChannelDestroyed; pusher.OnChannelException += pusher_OnChannelException; pusher.OnServiceException += pusher_OnServiceException; static void pusher_OnNotificationFailed(object sender, INotification notification, Exception error) { var n = (AppleNotification)notification; //error.Message ...获取推送出错的信息 } static void pusher_OnNotificationSent(object sender, INotification notification) { //消息推送成功后 var n = (AppleNotification)notification; //n.Payload.Alert.Body 获取推送的消息内容... } static void pusher_OnDeviceSubscriptionExpired(object sender, string expiredSubscriptionId, DateTime expirationDateUtc, INotification notification) { // 从数据库删除过期的expiredSubscriptionId } static void pusher_OnDeviceSubscriptionChanged(object sender, string oldSubscriptionId, string newSubscriptionId, INotification notification) { // 把数据库中的oldSubscriptionId更新为newSubscriptionId }
