用户允许该应用时触发事件

Question

用户登录时会触发此事件

FB.Event.subscribe('auth.login', function(response) {
          //
        });

但我只是在寻找当用户从auth对话框中启用应用程序时触发的事件？

Answer 1

FB.Event.subscribe('auth.authResponseChange', function(response) {
  alert('The status of the session is: ' + response.status);
});

auth.authResponseChange - 在authResponse更改时触发，因此理论上当用户允许来自auth对话框的应用程序时，这将触发。

此外，在提示用户允许该应用的代码中：

FB.getLoginStatus(function(response) {
  if (response.authResponse) {
    // logged in and connected user, someone you know
  } else {
    // no user session available, someone you dont know
   FB.login(function(response) {
   if (response.authResponse) {
      console.log(reponse);
      // here will be all the response details from confirmed app
   } else {
     console.log('User cancelled login or did not fully authorize.');
   }
 }, {scope: 'email'});
  }
});
