Question

我第一次尝试使用FCM，所以只使用他们的示例代码。事实上，我甚至发送他们的示例消息。以下代码直接来自文档（除了来自他们的示例消息传递android工具的令牌），它失败了：

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，您可以看到在创建文档时将从云功能发送通知。该函数被称为OK，但日志显示为：

Answer 1

正如Carlos Fernandez Sanz所指出的，其原因之一是客户端和服务器连接到了不同的Firebase项目。项目名称显示在客户端上的google-services.json文件中和服务器上的凭据json中。

Answer 2

我的json字符串中有"，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'],
            ],
            GuzzleHttp\RequestOptions::JSON => [
                "message" => [
                    "token"  => "dflhjldkjhflksfshklsf",
                    "notification" => [
                        "title" => "FCM Message",
                        "body" => "This is an FCM notification message!"
                    ]
                ]
            ]
        ]);

收件人：

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

希望有帮助！
