Question

这是一个可选权限，但我无法在我的画布应用中跳过它，当我点击此“权限”上的“跳过”时，我的页面会被重定向，一次又一次地请求此权限。任何人都知道为什么会这样？

非常感谢！：）

Answer 1

如果没有看到您的身份验证码，很难确定，但我确信您有

检查授予的权限，如果缺少某些权限，则重定向回对话框，或
使用JS SDK中指定的某些权限调用FB.login()，类似

如果您没有考虑跳过请求的用户

，

两者都会导致循环

显然，他正在使用facebook sdk库。我从未听说过跳过权限。在构建用于身份验证的URL时，可以在适当的函数中设置它们。值得检索登录身份验证流程，但请尝试oauth_url += '&scope=email'而不是您拥有的内容？或者，您可以尝试构建没有范围的oauth URL，并查看应用程序要求的权限。如果它要求特定权限，请检查登录功能并查看是否已设置某些权限。如果我没记错的话，应该是在facebook.php文件中。

无法跳过“publish_permission”，总是要求它
