FCM - 以编程方式向用户段发送推送通知 [英] FCM - Programatically Send Push Notification To User Segments

问题描述

我可以将通知从Firebase控制台发送到单个设备，主题和用户细分。

我想将推送通知发送给用户细分。我搜索了很多，但我只是得到脚本发送通知单用户或主题不给用户细分。

我尝试了下面的代码

  var client = new RestClient（https://fcm.googleapis.com/fcm/send）; 
 var request = new RestRequest（Method.POST）; 
 request.AddHeader（content-type，application / json）; 
 request.AddHeader（authorization，key = mykey）; 
 request.AddParameter（application / json，\\\
\\\
 {\to \：\user-segment-name \，\\\
\notification ：\\ \\ \\身体\\：\\ \\测试消息\\，\\ \\ \\ \\ \\标题\：\葡萄牙与丹麦\\\\
}， \\priority \：\high \\\\
}，ParameterType.RequestBody）; 
 IRestResponse响应= client.Execute（request）; 
 Response.Write（response.Content）; 
  

我在下面得到了回应

  { multicast_id：5837227475989925972， 成功：0， 失败：1， canonical_ids：0 结果：[{ 错误： InvalidRegistration}] } 
  

解决方案

不幸的是，似乎以编程方式发送给用户段仍然是不可能的。参考这里：

但是您不会能够将通知发送到Firebase用户标识符（UID）和 / li>

只能通过Firebase控制台

I am able to send the notification to single device, topics and user segment from Firebase Console.

I want to send the push notification to a user segment. I searched a lot but I'm only getting script to send notification to Single User or Topic not to user segments.

I tried the below code

var client = new RestClient("https://fcm.googleapis.com/fcm/send");
var request = new RestRequest(Method.POST);
request.AddHeader("content-type", "application/json");
request.AddHeader("authorization", "key=mykey");
request.AddParameter("application/json", "\n\n{\"to\" : \"user-segment-name\",\n\"notification\" : {\n    \"body\" : \"test message\",\n    \"title\" : \"Portugal vs. Denmark\"\n    },\n    \"priority\":\"high\"\n}", ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
Response.Write(response.Content); 

And i am getting the response below

{"multicast_id":5837227475989925972,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}

解决方案

Unfortunately, it seems that sending to user segments programatically still isn't possible. Reference here:

But you won't be able to

1. send notifications to a Firebase User Identifier (UID) and

2. send notifications to user segments (targeting properties & events like you can on the user console).

It's only possible via the Firebase Console.
