HarmonyOS web组件的onInterceptRequest方法，能否支持异步方式返回WebResourceResponse

build() { 
 
  Column() { 
    Web({ src: $rawfile('catch.html'), controller: this.webviewController }) 
      .onInterceptRequest((event) => { 
        if (event) { 
          console.log('url123456:' + event.request.getRequestUrl()) 
        } 
 
        const url = event!.request.getRequestUrl(); 
 
        // const regExp = new RegExp("^(http|https)[w/-]+(.jpg)$"); 
        console.log(url.endsWith(".jpg") + '123456') 
        if (!url.endsWith(".jpg")) return null; 
        try { 
          // const responseweb = new WebResourceResponse(); 
          let url2='https://index.html/1.jpg'; 
          this.xxxx(url2).then(fd => { 
            this.responseweb.setResponseData(fd); 
            this.responseweb.setResponseCode(200); 
            this.responseweb.setReasonMessage('OK'); 
            this.responseweb.setResponseIsReady(true); 
            console.log(fd+" 1234567") 
          }); 
          this.responseweb.setResponseMimeType('image/*'); 
          this.responseweb.setResponseIsReady(false); 
          console.log(this.responseweb.getResponseData().toString+"123456") 
          return this.responseweb; 
 
        } catch (error) { 
          console.error(`[Demo]Code: ${error.code},Message: ${error.message} `); 
          return null 
        } 
 
      }) 
  } 
}
