Question

我正在使用Facebook Graph v5 sdk进行登录和张贴在墙上，但是出现一些错误。我已经成功登录并成功获取了用户的年龄，生日等详细信息，但是在使用此代码在Facebook上发布时

$fb->post('/me/feed', $attachment, $accessToken);

出现一些权限错误，如下所示。

错误：致命错误：未捕获的Facebook \ Exceptions \ FacebookAuthorizationException：（＃200）需要publish_actions权限，或以具有足够管理权限的管理员身份需要manage_pages和publish_pages

    $loginURL = $helper->getLoginUrl($redirectURL, $permissions);
    echo $loginURL;

您似乎正在尝试使用不包含publish_actions权限的令牌在用户墙上发布。

您应该首先阅读有关publish_actions的变更日志：https://developers.facebook.com/docs/graph-api/changelog/breaking-changes
