看起来您正在向应用程序授予 r_fullprofile 权限.这是正确的成员权限.但是，这只会将您的完整个人资料字段授予已认证的用户(位置"和教育"字段由该用户组成).使用您的1级和2级学位，您只能检索具有基本个人资料字段的字段(作为 r_basicprofile 成员权限的一部分)

Looks like you're granting r_fullprofile permissions to your application. That's the correct member permission. However, that will only grant you full profile fields to the authenticated user (of which the Position and Education fields are composed of). With your 1st and 2nd degree connections, you can only retrieve fields that Basic Profile fields (as part of the r_basicprofile member permission)
