Question

我正在使用VueJS和Firebase Auth（NPM - 版本5.6.0）。我需要将匿名用户转换为Google作为提供商的注册用户。我尝试了recently updated sample from the Firebase docs：

        anonymousToGoogle: function () {
      var googleUser
      var provider
      var credential = firebase.auth.GoogleAuthProvider.credential(googleUser.getAuthResponse().id_token)
      firebase.auth.currentUser.linkWithRedirect(provider)
      firebase.auth().currentUser.linkAndRetrieveDataWithCredential(credential).then(function (usercred) {
        var user = usercred.user
        console.log('Anonymous account successfully upgraded', user)
      }, function (error) {
        console.log('Error upgrading anonymous account', error)
      })
    }
  }

Button（使用VuetifyJS框架）：

<v-btn block @click="anonymousToGoogle()">CONVERT - Login with Google</v-btn>

单击按钮后，控制台显示此错误：

[Vue警告]：“click”的事件处理程序出错：“TypeError：不能读取属性'getAuthResponse'未定义“

您只需在匿名用户上拨打linkWithRedirect即可。

// Assuming you previously signed in anonymously.
firebase.auth().signInAnonymously().then(function(result) {
  var provider = new firebase.auth.GoogleAuthProvider();
  // Page will redirect to google and then back. You can get back
  // result via getRedirectResult().
  return firebase.auth().currentUser.linkWithRedirect(provider);
}).catch(function(error) {
  // Error occurred.
});

使用Firebase转换匿名用户：无法读取未定义的属性“getAuthResponse”
