友達の名前、現在の場所、プロフィール写真を含むリストを取得したいと考えています。GRAPH API エクスプローラー ツールでクエリとアクセス トークン (必要なスコープ パラメーターを使用) を実行したところ、正常に動作しました --> https://developers.facebook.com/tools/explorer?method=GET&path=me%2Ffriends% 3Ffields%3Dname%2Clocation%2Cpicture
しかし、アプリケーションを実行するたびに、必要なスコープのないアクセス トークンを取得します (スコープがありません)。スコープをアクセス トークンに送信するにはどうすればよいですか?
アクセストークンに付与したいスコープ: スコープ: friends_location user_location user_relationships
私はローカルホスト環境で働いています。
