ios - 火力地堡， swift : Send a push notification to specific user given device token

Question

我有一个 Firebase Swift 聊天应用程序，我想在其中向特定用户发送推送通知。我已经捕获并可以访问用户的设备 token 。

所有引用资料都提到必须有一个“网络应用程序”来管理它，但我还没有设法找到这方面的任何具体示例。

1. 是否需要一个网络应用程序来管理 Firebase 的推送通知？

2. 如果是这样，是否有任何示例说明这是如何工作的？

谢谢。

Answer 1

• 首先为 Firebase 云消息传递 进行所有配置。可以关注这个链接https://firebase.google.com/docs/cloud-messaging/ios/client
• 现在您需要为要向其发送推送通知的关联用户访问 Firebase 注册 token 。您可以按照以下步骤获取此 token :
  1. 将 'Firebase/Messaging' pod 添加到您的项目。
  2. 在您的 AppDelegate.swift 文件中导入 FirebaseMessaging。
  3. 使 MessagingDelegate 协议(protocol)符合您的 AppDelegate 类。
  4. 编写 didRefreshRegistrationToken 委托(delegate)方法并获取用户的注册 token :

• 现在您已准备好向您的特定用户发送推送通知。发送通知如下:

  func sendPushNotification(payloadDict: [String: Any]) {
     let url = URL(string: "https://fcm.googleapis.com/fcm/send")!
     var request = URLRequest(url: url)
     request.setValue("application/json", forHTTPHeaderField: "Content-Type")
     // get your **server key** from your Firebase project console under **Cloud Messaging** tab
     request.setValue("key=enter your server key", forHTTPHeaderField: "Authorization")
     request.httpMethod = "POST"
     request.httpBody = try? JSONSerialization.data(withJSONObject: payloadDict, options: [])
     let task = URLSession.shared.dataTask(with: request) { data, response, error in
        guard let data = data, error == nil else {
          print(error ?? "")
          return
        }
        if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {
          print("statusCode should be 200, but is \(httpStatus.statusCode)")
          print(response ?? "")
        }
        print("Notfication sent successfully.")
        let responseString = String(data: data, encoding: .utf8)
        print(responseString ?? "")
     }
     task.resume()
  }
  

• 现在调用上面的函数:

  let userToken = "your specific user's firebase registration token"
  let notifPayload: [String: Any] = ["to": userToken,"notification": ["title":"You got a new meassage.","body":"This message is sent for you","badge":1,"sound":"default"]]
  self.sendPushNotification(payloadDict: notifPayload)
