发送 Firebase Swift 使用 NSURLSession HTTP 推送 Post

Question

我设置了我的应用程序，以便用户在登录时使用他们的用户 UID 订阅主题。每当一个用户向另一个用户发送消息时，我将调用我希望触发推送的下面的函数。

func sendPushNotification(toUser: String, message: String) {
        let urlString = "https://fcm.googleapis.com/fcm/send"
        let topic = "\topic\(toUser)"
        let url = NSURL(string: urlString)!
        let paramString  = "to=\(topic)"

        let request = NSMutableURLRequest(URL: url)
        request.HTTPMethod = "POST"
        request.HTTPBody = paramString.dataUsingEncoding(NSUTF8StringEncoding)!
        request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")

        let task =  NSURLSession.sharedSession().dataTaskWithRequest(request)  { (data, response, error) in
            do {
                if let jsonData = data {
                    if let jsonDataDict  = try NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.AllowFragments) as? [String: AnyObject] {
                        NSLog("Received data:\n\(jsonDataDict))")
                    }
                }
            } catch let err as NSError {
                print(err.debugDescription)
            }
        }

        task.resume()
    }

根据 Firebase 文档，我应该执行此 HTTP 请求：

Send to a single topic:

https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

{
  "to": "/topics/foo-bar",
  "data": {
    "message": "This is a Firebase Cloud Messaging Topic Message!",
   }
}

我正在努力查看我在 paramString 中传递的内容，以便根据他们的示例发送消息。另外，我在哪里定义 Authorization:key=

使用 Firebase Cloud Messaging 发送消息需要您在 Authorization header 中提供 服务器密钥 。顾名思义，此密钥只能在应用服务器（或您控制的其他基础设施）上运行的代码中使用。将服务器密钥放入您发送给用户的应用程序中，意味着恶意用户可以使用它代表您发送消息。

来自 Firebase documentation on sending messages to topics（强调我的）：

From the server side, sending messages to a Firebase Cloud Messaging topic is very similar to sending messages to an individual device or to a user group. The app server sets the to key with a value like /topics/yourTopic.
