Firebase FCM:无效参数

Question

我是第一次尝试FCM，所以只使用他们的示例代码。事实上，我什至在发送他们的示例消息。以下代码直接来自文档(除了来自其示例消息传递 android 工具的令牌(失败：

exports.onBroadcastCreated =    functions.firestore.document('/apath    /...').onCreate(async event => {
notification:{
title:"Portugal vs. Denmark",
body:"great match!"
},
token: 'eU2YUsi4Ugs:APA91bFH5bR9B1xosqrjvpw7HG4UkYTlDizmtra9pQRge-b4JxRbLjq9PVw91rqZytkUMKJXjPHd_dRlHHMk1bExCo_6Dxv99Vfp8MYz-H16Y9zmG8EFlWXNH4Tw_h6NRj2z1gLcz10m'
};
// Send a message to the device corresponding to the provided
// registration token.
return admin.messaging().send(message)
.then((response) => {
// Response is a message ID string.
console.log('Successfully sent message:', response);
})
.catch((error) => {
console.log('Error sending message:', error);
console.log(message);
});

}

因此，如您所见，在创建文档时，将从云函数发送通知。该函数称为 OK，但日志显示以下内容：

Answer 1

正如Carlos Fernandez Sanz指出的那样，其中一个原因是客户端和服务器连接到不同的Firebase项目。项目名称显示在客户端上的google-services.json文件中，以及服务器上的凭据 json 中。

Answer 2

我在 json 中的字符串中"，我将其更改为'并解决了问题！

$response = $client->post(
'https://fcm.googleapis.com/v1/projects/xxx/messages:send',[
'headers' => [
'Content-Type' => 'application/json',
'Authorization'     => 'Bearer ' . $token['access_token'],
],
GuzzleHttpRequestOptions::JSON => [
"message" => [
"token"  => "dflhjldkjhflksfshklsf",
"notification" => [
"title" => "FCM Message",
"body" => "This is an FCM notification message!"
]
]
]
]);

自：

$response = $client->post(
'https://fcm.googleapis.com/v1/projects/xxx/messages:send',[
'headers' => [
'Content-Type' => 'application/json',
'Authorization'     => 'Bearer ' . $token['access_token'],
],
GuzzleHttpRequestOptions::JSON => [
'message' => [
'token'  => 'dflhjldkjhflksfshklsf',
'notification' => [
'title' => 'FCM Message',
'body' => 'This is an FCM notification message!'
]
]
]
]);

希望对您有所帮助！
