我正试图检索用户登录我的Web应用程序的电子邮件；这是我的代码：
FB.api('/me', function(response) {
console.log(response.name + ', ' + response.email);
});
用户名正确，但电子邮件结果为
未定义
我要去哪里错了？

在登录过程中询问@Component
class Prototype
{
@Autowired
private Repository repository;
// Here Session is part of javx.websocket package and cannot be added as part of
// Java configuration class with a @Bean annotation
// In this case how can I use constructor injection?
private Session session;
Prototype(Session session)
{
this.session = session;
}
}
@Component
class PrototypeClient
{
@Autowired
private ApplicationContext context;
private void createNewPrototype(Session session)
{
Prototype prototype = context.getBean(Prototype.class, session);
}
}
@ServerEndpoint(value = "/resources")
class WebSocketController
{
private PrototypeClient client = ApplicationContext.getBean(PrototypeClient.class);
@OnMessage
void handleMessage(Session session, String message)
{
client.createNewPrototype(session);
}
}
权限：
email此外，您还需要询问要获取的字段：
FB.login((response) => {
// handle the response
}, {scope: 'email'});
确保用户甚至有电子邮件，这不是必需的。并确保您确实在登录弹出窗口中被要求提供FB.api('/me', {fields: 'name,email'}, (response) => {
console.log(response.name + ', ' + response.email);
});
权限。
侧面注意：我只会使用email，因此您可以看到整个对象，而不是某些console.log(response)值。
