ElectronJS Webview cookies未被清除

我试着用-

let session=require('electron');
  session.clearCache(function () {
    //   console.log("cache clear");
     });
    session.clearStorageData();

 session.defaultSession.cookies.get({}, (error, cookies) => {
  cookies.forEach((cookie) => {
    let url = '';
    // get prefix, like https://www.
    url += cookie.secure ? 'https://' : 'http://';
    url += cookie.domain.charAt(0) === '.' ? 'www' : '';
    // append domain and path
    url += cookie.domain;
    url += cookie.path;

    session.defaultSession.cookies.remove(url, cookie.name, (error) => {
      if (error) console.log(`error removing cookie ${cookie.name}`, error);
    });
  });
});

getWebContents() 但当我尝试时,“getWebContents()”在控制台上不可用。如何访问webview,然后清除会话,以便下一个用户无法使用上一个用户的凭据登录?
