DSbridge HarmonyOS适配问题

由于我们app里面很多模块是用h5写的，h5写的基于DSBridge，但是HarmonyOS版本的DSBridge js回调给h5不能直接传递给对象，直接转成string，这改变很大，这如果h5改的话，太多地方要改了。

@JavaScriptInterface() 
getSafeArea(data: string, handler: CompleteHandler) { 
  let safeAreaMap: Record<string, number> = { 
    "top": 0, 
    "left": 0, 
    "right": 0, 
    "bottom": 0 
  } 
 
  handler.complete(JSON.stringify(safeAreaMap)) 
}

请问有什么办法吗？

是可以直接传递对象的，下面是demo：

import { CompleteHandler, JavaScriptInterface, WebViewControllerProxy } from '@hzw/ohos-dsbridge' 
@Entry 
@Component 
struct webView { 
  private controller: WebViewControllerProxy = WebViewControllerProxy.createController() 
 
  aboutToAppear() { 
    this.controller.addJavascriptObject(new JsBridge()) 
  } 
  build() { 
    Column() { 
      Text('DsBridge 测试') 
      Web({ src: $rawfile('index.html'), controller: this.controller.getWebViewController() }) 
        .javaScriptAccess(true) 
        .javaScriptProxy(this.controller.getJavaScriptProxy()) 
    } 
    .height('100%') 
    .width('100%') 
  } 
} 
export class JsBridge { 
  @JavaScriptInterface() 
  testAsync(p: string, handler: CompleteHandler) { 
    let safeAreaMap: Record<string, number> = { 
      "top": 0, 
      "left": 0, 
      "right": 0, 
      "bottom": 0 
    } 
    handler.complete(safeAreaMap) 
  } 
}
<!-- index.html --> 
  <!DOCTYPE html> 
  <html> 
  <body id="box"> 
  <p>Hello World</p> 
  </body> 
  <script src="./dsbridge.js"></script> 
  <script> 
 
  dsBridge.call('testAsync', JSON.stringify({data: 200}), (msg) => { 
    document.body.innerHTML = JSON.stringify(msg) 
    updateMsg(msg) 
  }) 
  </script> 
  </html>
