【问题描述】：
我正在构建一个表单，并希望通过例如获取“first_name”和“last_name”等字段。 facebook 或 google 数据，但只接收一个对象，每个条目都是“null”
我尝试添加一个自定义 ScropeBuilder，获取不同的帐户。
我的应用程序仅将访问令牌提供给浏览器终端，因此我可以通过邮递员发送请求以获取我想要的数据。
令牌控制器：
package com.example.demo;
import com.restfb.DefaultFacebookClient;
import com.restfb.FacebookClient;
import com.restfb.Version;
import com.restfb.scope.FacebookPermissions;
import com.restfb.scope.ScopeBuilder;
import com.restfb.types.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.security.SecurityProperties;
import org.springframework.social.connect.ConnectionRepository;
import org.springframework.social.facebook.api.Facebook;
import org.springframework.social.facebook.api.FacebookProfile;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping(value="/tokencontroller")
public class TokenController {
@Autowired
Facebook facebook;
@Autowired
ConnectionRepository connectionRepository;
@RequestMapping(value = "/userdata/{accessToken}", method = RequestMethod.POST)
public UserModel userMod(@PathVariable(value = "accessToken") String accessToken) {
UserModel userModel = new UserModel();
ScopeBuilder scopeBuilder = new ScopeBuilder();
scopeBuilder.addPermission(FacebookPermissions.PUBLIC_PROFILE);
/*if(connectionRepository.findPrimaryConnection(Facebook.class) == null) {
return null;
}*/
System.out.println("\n \n \n accesstoken: "+accessToken);
FacebookClient fbClient = new DefaultFacebookClient(accessToken, Version.VERSION_4_0);
User user = fbClient.fetchObject("me",User.class);
System.out.println("User: "+user);
System.out.println("Firstname: "+user.getFirstName());
return userModel;
}
@RequestMapping(value = "/getURL")
public void getUrl(){
ScopeBuilder scopeBuilder = new ScopeBuilder();
scopeBuilder.addPermission(FacebookPermissions.PUBLIC_PROFILE);
FacebookClient client = new DefaultFacebookClient(Version.LATEST);
String url = client.getLoginDialogUrl("502780177145376","/connect/facebook",scopeBuilder);
System.out.println(url);
}
}
```

Below we include the Login Button social plugin. This button uses
the JavaScript SDK to present a graphical Login button that triggers
the FB.login() function when clicked.

console.log('statusChangeCallback');

testAPI();

// The person is not logged into your app or we are unable to tell.

// This function is called when someone finishes with the Login

});
// Now that we've initialized the JavaScript SDK, we call
// FB.getLoginStatus(). This function gets the state of the
// person visiting this page and can return one of three states to
// the callback you provide. They can be:
//
// 1. Logged into your app ('connected')
// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
// your app or not.
//
// These three cases are handled in the callback function.
FB.getLoginStatus(function(response) {
statusChangeCallback(response);

};
// Load the SDK asynchronously

var js, fjs = d.getElementsByTagName(s)[0];

js.src = "https://connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
// Here we run a very simple test of the Graph API after login is
// successful. See statusChangeCallback() for when this call is made.
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me',{"fields":"first_name"}, function(response) {
console.log('Successful login for: ' + response.name);
document.getElementById('status').innerHTML =
'Thanks for logging in, ' + response.name + '!';

}
function login(){
FB.login(function(response){
console.log("\n Response: "+response.connectionState);
try{
if(response == 'connected')
console.log("Connected: "+true);

console.log("not connected");
console.log("accesstoken: " + response.authResponse.accessToken);

console.log("is nich");
}
});
}
</script>
<button onclick="login()">Login Button</button>
<div id="status">
</div>
</body>
</html>
```
I expect the output to be:
```JSON
{
"firstName": John,
"lastName": Johnson,
"address": myAddress,
"birthDay": myBirthday,
"email": myEmail,
"gender": myGender
}
```
Actual output is:
```JSON
{
"firstName": null,
"lastName": null,
"address": null,
"birthDay": null,
"email": null,
"gender": null
}
```
When logging it in console there is no exception or error message, just:
```

I don't get why it's not fetching the correct userdata.
May anyone can help me?
