When I write code to authorize with facebook-sdk, I was confused so I write how to solve this problem.<\/p>\n
User move to laravel redirect controller when user click button.<\/p>\n
use Illuminate\\Support\\Str;\r\n\r\nclass OauthController\r\n{\r\n public function redirectToFacebook()\r\n {\r\n $state = Str::random(32);\r\n session()->put('state', $state);\r\n $sendData = [\r\n \"client_id\" => 'client_id-xxxxx-xxxx',\r\n \"redirect_url\" => 'https:\/\/hogehoge.com\/facebook\/callback',\r\n \"state\" => $state,\r\n \"response_type\" => 'code',\r\n ];\r\n $url = 'https:\/\/www.facebook.com\/v8.0\/dialog\/oauth?'.http_build_query($sendData);\r\n return redirect($url);\r\n }\r\n}<\/pre>\nYou need to set session ‘state’\u00a0 for XSRF.<\/p>\n
Then, you redirect to facebook authorize page.<\/p>\n
Yser come back to callback url you set in sendData After user authorize.<\/p>\n
Secondly<\/h2>\n
You set function for callback from facebook.<\/p>\n
use Facebook\\Facebook;\r\nuse Facebook\\PersistentData\\PersistentDataInterface;\r\n\r\nclass OauthController\r\n{\r\n...\r\n public function callbackFromFacebook(string $accessToken = null)\r\n {\r\n $facebook = new Facebook([\r\n 'app_id' => FACEBOOK_APPLICATION_ID,\r\n 'app_secret' => FACEBOOK_SECRET_ID,\r\n 'default_graph_version' => 'v2.9',\r\n 'persistent_data_handler' => new MyLaravelPersistentDataHandler(),\r\n ]);\r\n $helper = $facebook->getRedirectLoginHelper();\r\n if ($accessToken) {\r\n $accessToken = $helper->getAccessToken();\r\n }\r\n $response = $facebook->get('\/me?fields=id', $accessToken);\r\n $user = $response->getGraphUser();\r\n $userId =$user->getId();\r\n...\r\n }\r\n}\r\n\r\nclass MyLaravelPersistentDataHandler implements PersistentDataInterface\r\n{\r\n public function get($key) {\r\n return session()->get($key);\r\n }\r\n public function set($key, $value) {\r\n session()->put($key, $value);\r\n }\r\n}<\/pre>\nFirst, you make instance of Facebook.<\/p>\n
If you want to use\u00a0 FacebookDataHandler, you make FacebookDataHandler class and set persistent_data_handler key and value.<\/p>\n
getRedirectLoginHelper method is used to generate a “Login with Facebook” link and obtain an access token from a redirect.<\/p>\n
This method check session of state for csrf measures.<\/p>\n
Second, try to get user data with accessToken.<\/p>\n
There you can set field like id,email,first_name,family_name which you want to get at field.<\/p>\n
After this. you make user-data object by using\u00a0getGraphUser.<\/p>\n
This object can get user data by method.<\/p>\n
FInally, you write function you want.<\/p>\n
