如果发送的不是 firebase 控制台，则不会传递 Firebase 通知

Question

我遇到了一个非常奇怪的问题，从 Firebase 控制台发送的通知正在正确传送，这意味着项目已配置且证书正确，但是当我从应用程序发送通知时它不起作用。我正在使用以下方法发送通知。

func sendPushNotification(to token: String, title: String, body: String, Type: String) {

        let urlString = "https://fcm.googleapis.com/fcm/send"
        let url = NSURL(string: urlString)!
        let paramString: [String : Any] =
            [
                "message" :[
                    "to" : token,
                    "notification" : ["title" : title, "body" : body],
                    "data" : ["notification_type": Type]
                ],
                "to" : token
            ]

        print(paramString)
        let request = NSMutableURLRequest(url: url as URL)
        request.httpMethod = "POST"
        request.httpBody = try? JSONSerialization.data(withJSONObject:paramString, options: [.prettyPrinted])
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")
        request.setValue("key=AAAApQ9EAjg:XXXX", forHTTPHeaderField: "Authorization")
        let task =  URLSession.shared.dataTask(with: request as URLRequest)  { (data, response, error) in
            do {
                if let jsonData = data {
                    if let jsonDataDict  = try JSONSerialization.jsonObject(with: jsonData, options: JSONSerialization.ReadingOptions.allowFragments) as? [String: AnyObject] {
                        NSLog("Received data:\n\(jsonDataDict))")
                    }
                }
            } catch let err as NSError {
                print(err.debugDescription)
            }
        }
        task.resume()



    }

我也尝试过使用以下方法通过 curl 发送

<?php
/**
 * Created by PhpStorm.
 * User: ussaidiqbal
 * Date: 2020-02-17
 * Time: 19:45
 */

$url = "https://fcm.googleapis.com/fcm/send";
$token = "eMIK6wGOTUUutqp62vEIr-:XXXXXX";
$serverKey = 'AIzaSyCJFUydXXXXXXXXXX';
$title = "Title";
$body = "Body of the message";
$notification = array('title' =>$title , 'text' => $body, 'sound' => 'default', 'badge' => '1');
$arrayToSend = array('to' => $token, 'notification' => $notification,'priority'=>'high');
$json = json_encode($arrayToSend);
$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: key='. $serverKey;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST,

    "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);
//Send the request
$response = curl_exec($ch);
//Close request
if ($response === FALSE) {
    die('FCM Send Error: ' . curl_error($ch));
}
curl_close($ch);

我也曾尝试使用以下负载

通过 PostMan 发送

{
    "notification":{
        "title": "XXXXX",
        "body": "XXXXX"
    },
  "to": "XXXXXXX"
}

这是请求的响应

{
    "multicast_id": 36126XXXXXXXX,
    "success": 1,
    "failure": 0,
    "canonical_ids": 0,
    "results": [
        {
            "message_id": "0:1581960379105057~~~~~~~~~~"
        }
    ]
}

None 上面的方法似乎有效，我做错了什么？我已经尝试了 Legacy server key 和 Server key 但没有成功。有人遇到过这样的问题吗？

struct NotificationStruct: Codable {
    var notification: NotificationBodyStruct?
    var to: String?
    var time_to_live = 60000
}

struct NotificationBodyStruct: Codable {
    var title: String?
    var text: String?
    var sound: String?
}    



func sendNotificationtoken: String, name: String, completion: @escaping(Bool) -> Void) {
    do {
        let noti = NotificationStruct(notification: NotificationBodyStruct(title: name, text: text, sound: "default"), to: "\(token)", time_to_live: 6000)
        let body = try JSONEncoder().encode(noti)

        makeConnection(body: body) { (success) in
            DispatchQueue.main.async {

        }

        completion(true)
    })
    dataTask.resume()
}

我还认为您的 paramString 属性有误。试试看：

        let paramString: [String : Any] = [
            "to" : token,
            "notification" : ["title" : title, "text" : body],
            "time_to_live" : 60000,
            "sound" : "default"
        ]

所以在花了很多时间之后我弄明白了并且一切正常。因此，如果其他人遇到此问题，他们可以通过打开您的 AppDelegate.swift 文件来解决，找到一个函数 didRegisterForRemoteNotificationsWithDeviceToken 并替换为以下

 func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        print("APNs token retrieved: \(deviceToken)")
        // With swizzling disabled you must set the APNs token here.
         Messaging.messaging().apnsToken = deviceToken
    }

完成这一切后似乎一切正常。
