我已经实现了Oauth 2（google），所以我已经非常熟悉通行证，并且不确定为什么会出现此错误。
这是我得到的错误：
C:\Users\Elijah\.projects\tutorials\web-socket-io\node_modules\passport-local\lib\strategy.js:47
if (!verify) { throw new TypeError('LocalStrategy requires a verify callback'); }
^

如果有人对如何解决此错误有任何想法，请告诉我！

答案 0 :(得分：0)
我通过将回调函数放在 localStrategy 括号内解决了这个问题 像这样
passport.use( new LocalStrategy( {usernameField: 'email', passwordField: 'password', passReqToCallback: true}, function(username, password, done){ //your codes });
