缺少 FCM 令牌答案

【问题标题】：FCM token missing缺少 FCM 令牌
【发布时间】：2017-04-12 22:10:57
【问题描述】：

我正在尝试使用 Postman 测试 FCM，但即使有 FCM 令牌，我也总是收到以下错误。我在 Cloud Messaging 选项卡中获得了令牌：Firebase Cloud Messaging 令牌。

<HTML>
<HEAD>
    <TITLE>The request was missing an Authentification Key (FCM Token). Please, refer to section &quot;Authentification&quot; of the FCM documentation, at https://firebase.google.com/docs/cloud-messaging/server.</TITLE>
</HEAD>

这是我发送的内容。

POST /fcm/send HTTP/1.1
Host: fcm.googleapis.com
Cache-Control: no-cache
Postman-Token: 9109eb13-245f-0786-21a5-6207f5426b44

Content-Type:application/json
Authorization:key=AAAAfnYrKvU:APA91bFwgeM3zuFId6UDzvIHk9qZ3lKHnX-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
{  "data": {     "message": "This is a Firebase Cloud Messaging Topic Message!",    } }:

【解决方案1】：

花了几个小时后，我发现在 Postman 中，您必须将以下内容放在标题中。

Key: Content-Type
Value: application/json
Key: Authorization
Value: key=AAAAfnYrKvU:APA91bFwgeM3zuFId6UDzvIHk9qZ3lKHnX-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
(Firebase Cloud Messaging token)

然后点击 Body 并选择 Raw，在这里添加 json。

    {
        "data": {
            "title": "new messages",
            "score": "5x1",
            "time": "15:10"
        },
        "to": "/topics/alldevices"
    }

我还发现你不能通过消除“to”来发送到所有设备：你必须让你的应用订阅一个主题。就我而言，我让我的应用订阅了“所有设备”。

现在我可以发送“to”：“/topics/alldevices”，所有应用都会收到通知。

之前本来打算加个评论的，但是没赶上。您所做的步骤与我在此documentation 中提供的示例相同。干得好。
您还可以通过在“收件人”字段中提供InstanceID（令牌）来发送到各个设备。
是的，答案是正确的。我没有注意到在我的情况下是令牌本身之前的“key=”。

"notification": {
    "title": "Hello",

}

【讨论】：

'Authorization' 是标头名称，'key=AAAATI...' 是标头值。
抱歉耽搁了。是的，'Authorization' 是标头名称，'key=AAA....' 标头值 @arberg

这是使用令牌向设备发送通知的示例邮递员 POST 请求。

Type: POST
Url: https://fcm.googleapis.com/fcm/send

Headers
key: Content-Type,
value: application/json

key: Authorization,
value: key="This is the key in your FCM project console->Settings->Cloud Messaging->Server Key""

    body: "mode": "raw"

    { 
     "to": "Token/s received to mobile end",  
     "notification" : {
     "body" : "message",
     "content_available" : true,
     "priority" : "high",
     "title" : "title of the notification"
     }
    }

这是为单个移动设备发送推送通知的示例邮递员请求

content-type: application/json
authorization: key="<server key>"

JSON Body

  "notification":{
    "title":"Ionic 4 Notification",

@GauravInno's 的回答让我意识到我的服务器密钥不正确，我不知何故使用了错误的密钥。我从 Firebase 控制台获得了 serverKey：

在request.setValue("key=\(serverKey)", forHTTPHeaderField: "Authorization")下面的代码中使用：

var apsDict = [String: Any]()
// add values

guard let url = URL(string: "https://fcm.googleapis.com/fcm/send") else { return }
    
let serverKey = "AAAA ..."
    
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject: apsDict, options: [])
request.setValue("application/json", forHTTPHeaderField: "Content-Type")

// *** serverKey is used here ***
request.setValue("key=\(serverKey)", forHTTPHeaderField: "Authorization")

let task = URLSession.shared.dataTask(with: request)  { (data, response, error) in
        
    do {
        if let jsonData = data {
                
            print("jsonData: \(String(data: jsonData, encoding: .utf8)!)")
                
            if let jsonDataDict = try JSONSerialization.jsonObject(with: jsonData, options: .allowFragments) as? [String: AnyObject] {
                print("jsonData Success Received data:\n\(jsonDataDict))")
            }
        }
    } catch let err as NSError {
        print("jsonData Error: \(err.debugDescription)")
    }
}
task.resume()
