快手小程序webview无法接收到H5中postMessage发送的消息

使用的uniapp+vite+vue3运行的快手小程序，使用了webview嵌入H5页面，但是无法收到H5发送的消息：

<web-view :src="url" ref="webview" @message="handleMessage" />

const handleMessage = (event: any) => {  
  console.log(event, "event");  
  uni.showModal({  
    title: "消息",  
    content: JSON.stringify(event.detail),  
  });  
};

H5中引入了uniapp的sdk，官网没有快手小程序的sdk，H5代码
<script type="text/javascript" src="https://js.cdn.aliyun.dcloud.net.cn/dev/uni-app/uni.webview.1.5.2.js"></script>
