我在我的 grails 应用程序中使用 Spring Security Facebook 插件。它在身份验证后从 Facebook 页面返回时显示以下错误消息。facebook 用户详细信息未保存在数据库中。请帮助解决此错误并成功验证 Facebook 用户。提前致谢。

FacebookUser.groovy 域类

class FacebookUser {

    long uid
  String accessToken
  Date accessTokenExpires

    static belongsTo = [user: User]

    static constraints = {
        uid unique: true
    }
}

spring-security-facebook 应用程序的 Config.groovy 设置

grails.plugins.springsecurity.facebook.domain.classname='com.awnsys.gcx.FacebookUser'
grails.plugins.springsecurity.facebook.domain.appUserConnectionPropertyName = 'user'
grails.plugins.springsecurity.facebook.appId='APPID'
grails.plugins.springsecurity.facebook.secret='secretID'

grails.plugins.springsecurity.facebook.autoCreate.enabled=true
grails.plugins.springsecurity.facebook.autoCreate.roles=['ROLE_USER', 'ROLE_FACEBOOK',]

以下是用户在 facebook 中接受应用程序后从 facebook 重定向时在浏览器中显示的错误消息

对于那些正在实现 FacebookAuthService 并遇到 Facebook 和 FacebookProfile 类被标记为错误的问题的人，请确保将这两个插件添加到 BuildConfig.groovy 文件中

compile ":spring-social-core:0.1.31"
compile ":spring-social-facebook:0.1.32"

注意：Spring Social Facebook 与 Spring Security Facebook 不是同一个插件。所以如果你有上面的代码，你仍然需要编译 Spring Social 插件。

compile ':spring-security-core:2.0-RC2'
compile ':spring-security-facebook:0.15.2-CORE2'

默认情况下，插件会生成用户名facebook_%UID%（facebook_100005487962357来自您的堆栈跟踪）。似乎您的User域需要.username字段电子邮件（并且有这样的限制），因此无法保存。

在这种情况下，我建议您通过实现FacebookAuthService.createAppUser方法来实现自己的填充用户对象的逻辑。请参阅文档：http ://splix.github.io/grails-spring-security-facebook/guide/5%20Customization.html#5.1%20Using%20FacebookAuthService

而且，Facebook 身份验证插件不知道用户电子邮件（默认情况下 Facebook 登录不提供），您必须从 Facebook API 获取它，请参见示例：https ://github.com/splix/grails-facebook-authentication -example/blob/master/grails-app/services/FacebookAuthService.groovy#L51
