登陆信息的cookie应该在什么时机注入？如何确保刚刚打开的web能注入登陆信息cookie

import { webview } from '@kit.ArkWeb' 
 
webview.once("webInited", () => { 
  console.log("setCookie"); 
  webview.WebCookieManager.configCookie("https://www.example.com", 'a=b,c=d,e=f'); 
}) 
 
@Entry 
@Component 
struct WebComponent { 
  controller: webview.WebviewController = new webview.WebviewController(); 
 
  build() { 
    Column() { 
      Web({ src: 'www.example.com', controller: this.controller }) 
    } 
  } 
}
