我添加了键值对:

"requireInteraction": true

但桌面Chrome中的通知在20秒后仍然消失.有人知道Firebase是否支持这个键值对吗？谢谢!

我的例子如下.请换[...]到你的.

curl -X POST -H "Authorization: key=[...]" -H "Content-Type: application/json" -d '{
  "notification": {
    "requireInteraction": true,     
    "title": "This is custom title",
    "body": "this is custom body",
    "click_action": "https://google.com",
    "data" : {"requireInteraction": true  }
 },
  "to": "[...]",
}' "https://fcm.googleapis.com/fcm/send"

https://example.com触发 ajax 预请求（beforeSend）到https://api.example.com (nginx)

$.ajax({
    method: "POST",
    url: 'https://api.example.com',
    xhrFields: {withCredentials: true},
    data: {...},
    success: function(msg) {...},
    beforeSend: function(request){
        var token = 'xxxxxx';
        request.setRequestHeader('Authorization', 'Bearer ' + token);
    },
    complete: function(msg) {},
    error: function(xhr, ajaxOptions, thrownError) {}
});

Chrome 控制台返回错误消息

XMLHttpRequest 无法加载https://api.example.com/auth。预检响应中的 Access-Control-Allow-Headers 不允许请求标头字段授权。

我可以使用内存来迁移我的数据库并启动服务器吗？

我的/配置/数据库.php

'sqlite' => array(
    'driver' => 'sqlite',
    'database' => ':memory:', // fail
    // 'database' => 'database', // success 
    'prefix' => '',
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
),

并迁移表并启动laravel服务

$ php artisan migrate:refresh 
$ php artisan serve

我使用 driver=sqlite + database=database 一切正常，

我使用driver=sqlite + database=:memory，错误信息来自127:0.0.1 说数据库表尚未创建。
