Google chrome 谷歌浏览器推送通知缓存

我正在使用google chrome推送通知向我的用户发送推送通知。 我制作了如下教程：

它正在工作，但当我更改“sw.js”文件上的“message”时出现问题。它不会立即改变，当我发送推送消息时，用户会收到上一条消息

请帮帮我

看起来您正在尝试发送数据，如下所示：

 $fields = array(
    'registration_ids' => $registrationIDs,
    'data' => array( "message" => $message ),
);

这是web推送的错误做法。数据属性特定于GCM，不受Chrome支持。要发送数据，您需要加密有效负载。也许可以看看：

其次，您需要在服务工作者中更改showNotification（）代码以使用此数据。（尝试调用

console.log（event.data）

）

 $fields = array(
    'registration_ids' => $registrationIDs,
    'data' => array( "message" => $message ),
);
