我正在尝试向主题发送FCM消息.但是从服务器收到提供了无效的主题值"错误.
I am trying to send an FCM message to a topic. But getting "Invalid topic value provided" error from the server.
Json有效载荷
{ "message":{ "topic":"/topics/news", "data":{ "title":"Hellow World", "message":"This is the Topic Message", "type1":"100", "type2":"abc" } } }响应
{ "error":{ "code":400, "message":"Request contains an invalid argument.", "status":"INVALID_ARGUMENT", "details":[ { "@type":"type.googleapis/google.rpc.BadRequest", "fieldViolations":[ { "field":"message.topic", "description":"Invalid topic value provided." } ] }, { "@type":"type.googleapis/google.firebase.fcm.v1.FcmError", "errorCode":"INVALID_ARGUMENT" } ] } }我尝试将主题值设置为新闻"(不带'/topics/'),但会引发相同的错误.我可以从Firebase控制台将消息发送到该主题,而不会出现任何问题.
I have tried topic value as "news" (without '/topics/') but it throws same error. I can send message to the topic from firebase console without any problem.
任何帮助表示赞赏. TIA
Any help appreciated. TIA
Edit1-下面的通知有效负载工作正常,但数据有效负载不起作用.根据文档,也允许数据有效载荷 firebase.google /docs/cloud-messaging/android/topic-messaging 请求
Edit1 - Notification payload below works fine but data payload doesn't work. As per documentation, data payloads too are allowed firebase.google/docs/cloud-messaging/android/topic-messaging Request
{ "message":{ "topic" : "foo-bar", "notification" : { "body" : "This is a Firebase Cloud Messaging Topic Message!", "title" : "FCM Message", } } }这行得通.我的代码中有一个小错误,该错误为该主题添加了其他引号.下面的请求就像一个魅力
EDIT2 : This works. I had a small bug in my code which was adding additional quotes to the topic. Below request works like a charm
{ "message":{ "topic":"news", "data":{ "title":"Hellow World", "message":"This is the Topic Message", "type1":"100", "type2":"abc" } } }推荐答案
根据 doc 您的请求应如下所示:
according to doc yor request should be like this:
fcm.googleapis/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!", } }更多推荐
提供的主题值无效
