Question

您好我正在尝试向使用Swift订阅特定主题的所有设备发送通知。我想通过代码而不是Firebase控制台手动发送推送。这是我写的代码。

public static func sendPush(){
    if let url = URL(string: "https://fcm.googleapis.com/fcm/send"){
        var urlRequest: URLRequest = URLRequest(url: url)
        urlRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")
        urlRequest.addValue("key = AIzaSyBaaaaaaaaaaaa-NbAUq3iMYmw", forHTTPHeaderField: "Authorization")
        let dic: Dictionary<String, Any> = [
            "to" : "/topics/News",
            "priority" : "high",
            "notification" :[
                "body" : "This is a notification",
                "title" : "FCM Notification"
            ]

        ]


        do{
            let data = try JSONSerialization.data(withJSONObject: dic, options: .prettyPrinted)
            urlRequest.httpBody = data
            urlRequest.httpMethod = "POST"
            print("JSON Object Serialized")
        }
        catch{

        }

        let task = URLSession.shared.dataTask(with: urlRequest, completionHandler: {
            data, response, error in
            print("Inside Task")
            if error != nil{
                print("Push \(error?.localizedDescription)")
            }
            if response != nil {
                print("Data : \(response)")
            }
        })
        task.resume()
    }
}

当我通过调用它执行上述功能时，我得到状态代码200.这意味着没问题，请求成功。但订阅此主题的我的设备不会收到通知。我也订阅了通知，但没有任何反应。当我尝试使用Firebase控制台向各个设备发送通知时，他们会收到通知，但不会通过代码收到通知。我正在阅读此文档Tutorial

这是在请求完成后在控制台中打印的内容

Data : Optional(<NSHTTPURLResponse: 0x170225560> { URL: https://fcm.googleapis.com/fcm/send } { status code: 200, headers {
"Cache-Control" = "private, max-age=0";
"Content-Encoding" = gzip;
"Content-Length" = 54;
"Content-Type" = "application/json; charset=UTF-8";
Date = "Fri, 12 May 2017 21:14:52 GMT";
Expires = "Fri, 12 May 2017 21:14:52 GMT";
Server = GSE;
"alt-svc" = "quic=\":443\"; ma=2592000; v=\"37,36,35\"";
"x-content-type-options" = nosniff;
"x-frame-options" = SAMEORIGIN;
"x-xss-protection" = "1; mode=block";
} })

请帮助我解决这个问题，并告诉我我做错了什么，我应该如何取得成功？谢谢。
