如何使用Grails中的OAuth插件从facebook获取个人资料信息

grails:
  plugin:
    oauth:
      providers:
        facebook:
          api_key: YOUR_FACEBOOK_API_KEY
          api_secret: YOUR_FACEBOOK_API_SECRET
          successUri: /oauth/facebook/success
          failureUri: /oauth/facebook/failure

import grails.plugin.oauth.OAuthController

class MyController extends OAuthController {
    def facebookService

    def success() {
        def accessToken = fetchAccessToken('facebook')
        def profile = facebookService.getProfile(accessToken)
        // 处理个人资料信息
    }

    def failure() {
        // 处理授权失败情况
    }
}

import grails.plugin.oauth.OAuthUtils

class FacebookService {
    def oauthUtils

    def getProfile(String accessToken) {
        def response = oauthUtils.get("https://graph.facebook.com/me", [access_token: accessToken])
        if (response.status == 200) {
            return response.data
        } else {
            // 处理获取个人资料信息失败情况
        }
    }
}
