我已根据passportjs docs设置了我的facebook身份验证:

var passport = require('passport')
  , FacebookStrategy = require('passport-facebook').Strategy;

passport.use(new FacebookStrategy({
    clientID: FACEBOOK_APP_ID,
    clientSecret: FACEBOOK_APP_SECRET,
    callbackURL: "http://www.example.com/facebook/callback"
  },
  function(accessToken, refreshToken, profile, done) { ... });
  }
));

app.get('/login/facebook', passport.authenticate('facebook'))
   .get('/facebook/callback', passport.authenticate('facebook', {successRedirect: '/', failureRedirect: '/login'}));

这一切都很好.但是,当我想在启动登录请求之前自动将用户重定向到用户所在的页面时,有些情况(例如令牌过期).所以我尝试通过登录请求(从客户端到服务器到Facebook并返回)检查查询字符串参数.但是我无法在callbackURL中看到指定它的方法.

此外,当我尝试将一些上下文参数硬编码到config callbackURL(例如:" http://www.example.com/facebook/callback?redir=lastUserPage ")时,我得到一个OAuth解析错误.有趣的是,Facebook确实对访问代码以及redir param做出了正确的响应,但它在OAUTH异常时失败了:

FacebookTokenError: Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request
