我的代码中有一个错误.我能够登录并检索用户信息.但又signinCallback被召唤了(我不知道怎么回事).它显示我之前的用户信息已经消失!这是HTML方面:

<span id="signinButton">
    <span
        class="g-signin"
        data-callback="signinCallback"
        data-clientid="CLIENT_ID"
        data-cookiepolicy="single_host_origin"

    chooseAuthProvider();

function chooseAuthProvider() {
  if (AuthStates.google && AuthStates.facebook) {
    if (AuthStates.google['access_token']) {
      // Signed in with Google, you can now use Google+ APIs.
      console.log(AuthStates.google);
      gapi.client.load('plus','v1', function(){
        var request = gapi.client.plus.people.get({
          'userId': 'me'
        }); 
        request.execute(function(resp) {
          document.getElementById('cname').value =resp.displayName;
          document.getElementById('cemail').value =resp.emails[0].value;
          console.log('Retrieved profile for:' …
