firebase 云消息传递请求包含无效参数 [英] firebase cloud messaging Request contains an invalid argument

问题描述

我在使用 Firebase 云消息管理 API 发送消息时出错.

I am getting error while sending message using Firebase cloud messaging admin API.

错误信息如下

原因:com.google.api.client.http.HttpResponseException: 400 Bad Request{错误": {代码":400，"message": "请求包含无效参数.",错误":[{"message": "请求包含无效参数.",域":全球"，原因":错误请求"}],状态":INVALID_ARGUMENT"}}

Caused by: com.google.api.client.http.HttpResponseException: 400 Bad Request { "error": { "code": 400, "message": "Request contains an invalid argument.", "errors": [ { "message": "Request contains an invalid argument.", "domain": "global", "reason": "badRequest" } ], "status": "INVALID_ARGUMENT" } }

让我把我的管理员配置放在这里..

Let me put my admin configuration here..

FileInputStream serviceAccount = new FileInputStream("My service accout file.json");

FirebaseOptions options = new FirebaseOptions.Builder().setCredentials(GoogleCredentials.fromStream(serviceAccount))
                    .setDatabaseUrl("https://deliveryeat-1aa42.firebaseio.com").build();

FirebaseApp.initializeApp(options);

消息发送代码如下

// This registration token comes from the client FCM SDKs.
String registrationToken = "YOUR_REGISTRATION_TOKEN";

// See documentation on defining a message payload.
Message message = Message.builder().putData("score", "850").putData("time", "2:45").setToken(registrationToken).build();

// Send a message to the device corresponding to the provided
// registration token.
String response = FirebaseMessaging.getInstance().sendAsync(message).get();
// Response is a message ID string.
System.out.println("Successfully sent message: " + response);

我正在使用的 maven 依赖项如下

maven dependencies that i am using is following

<dependency>
    <groupId>com.google.firebase</groupId>
    <artifactId>firebase-admin</artifactId>
    <version>5.9.0</version>
</dependency>

那么任何人都可以帮助我吗?我做错了什么?

So can anyone help me in this? What am I doing wrong?

推荐答案

我怀疑您的 registrationToken 格式无效.它应该是 152 个字符.

I suspect that your registrationToken has an invalid format. It should be 152 characters.

要确认这一点，请尝试使用 setTopic("test") 而不是 setToken(registrationToken).

To confirm that, try building your message with setTopic("test") instead of setToken(registrationToken).
