在Facebook Graph API中，获取用户电子邮件地址和性别的API调用是什么？
I'm using the Graph API and the Facebook SDK for PHP with the help of this link: https://developers.facebook.com/docs/php/howto/profilewithgraphapi/4.0.0. This is the code:
use Facebook\FacebookRequest;
use Facebook\GraphUser;
use Facebook\FacebookRequestException;
if($session) {
try {
$user_profile = (new FacebookRequest(
$session, 'GET', '/me'
))->execute()->getGraphObject(GraphUser::className());
echo "Name: " . $user_profile->getName();
} catch(FacebookRequestException $e) {
echo "Exception occured, code: " . $e->getCode();
echo " with message: " . $e->getMessage();
}
}
I'm at the point where I'm able to get a user's name by using user_profile->getName();, I can also get his/her first name, last name, middle name, etc., according to the API calls here: https://developers.facebook.com/docs/php/GraphObject/#user-instance-methods. I know it is possible to get a user's email address and gender, but in the previous link I didn't find any API calls to be able to get this information.
For Facebook SDK for PHP, what are the API calls to get a user's email address and gender?
Thank you very much.
我借助此链接使用Graph API和Facebook SDK for PHP： https://developers.facebook.com/docs/php/howto/profilewithgraphapi/4.0.0 。 这是代码： p>
使用Facebook \ FacebookRequest;
use Facebook \ GraphUser;
use Facebook \ FacebookRequestException;
if（$ session）{
尝试 {
$ user_profile =（新的FacebookRequest（
$ session，'GET'，'/ me'
）） - ＆gt; execute（） - ＆gt; getGraphObject（GraphUser :: className（））;
echo“姓名：”。 $ user_profile-＆gt; getName（）;
}} catch（FacebookRequestException $ e）{
echo“异常发生，代码：”。 $ e-＆gt; getCode（）;
echo“with message：”。 $ e-＆gt; getMessage（）;
}
}

我正处于能够获得 用户的名字通过 user_profile-＆gt; getName（）; code>，我也可以根据这里的API调用得到他/她的名字，姓氏，中间名等： https://developers.facebook.com/docs/php/GraphObject/#user-instance - 方法。 我知道可以获取用户的电子邮件地址和性别，但在上一个链接中，我没有找到任何API调用来获取此信息。 p>
对于Facebook SDK for PHP，获取用户电子邮件地址和性别的API调用是什么？ p>
非常感谢。 p>

Have a look at
- https://developers.facebook.com/docs/graph-api/reference/v2.2/user#fields
- https://developers.facebook.com/docs/graph-api/using-graph-api/v2.2#fields
to get an overview what fields and edges you can query for the user object. In your case, that should be
/me?fields=id,gender,email
or
new FacebookRequest(
$session, 'GET', '/me?fields=id,gender,email'
)
Be aware that you'll need the user_email permission to be able to request the email field.
To get specific fields, use the getProperty() method as described at https://developers.facebook.com/docs/php/GraphObject/#getproperty
echo $user_profile->getProperty('gender');
