我正在获取用户名，但我没有获取到。请任何人帮助我我做错了什么以及必须做的事情 do.Below 我给了代码也请找到它。

function fblogin() {
 FB.login(function(response) {
  if (response.authResponse) {
   alert("if");
   getUserInfo(); // Get User Information.
  } else {
   console.log('Authorization failed.');
  }
 }, {
  scope : 'email'
 });

}

function getUserInfo() {
 FB.api('/me', {fields: 'name, username, password, email, first_name, middle_name, last_name, gender, hometown, birthday'}, function(response) {
  alert("name=" + response.name);
  alert("username=" + response.username);
  alert("password=" + response.password);
  alert("id=" + response.id);

Answer 1

FB.api('/me', {fields: 'name,email,first_name,last_name'}, function(response) {
    ...
});

它被称为"Declarative Fields"，你必须在API调用中指定你想要获取的字段。

顺便说一句，根本不可能得到 phone 号码或用户名（只有真实姓名）。

用户的现有字段table：https://developers.facebook.com/docs/graph-api/reference/v2.6/user

现有权限：https://developers.facebook.com/docs/facebook-login/permissions
