我正在尝试使用 Koa 2 和护照创建一个简单的用户注册/登录 api。
尝试登录时出现问题。
这是路线的代码；
import {
authEmail,
generateToken
} from '../../auth';
import User from '../../models/user';
export default (router) => {
router.post('/auth/email', authEmail(), generateToken());
router.post('/auth/register', register, generateToken());
};
async function register(ctx, next) {
const { name, email, password } = ctx.request.body;
// TODO - improve validation
if (name && email && password) {
let user = await User.findOne({ email });
if (!user) {
user = new User({
name,
email
});
user.password = user.generateHash(password);
await user.save();
ctx.passport = {
user: user._id,
};
console.log(ctx.passport)
await next();
} else {
ctx.status = 400;
ctx.body = { status: 'error', message: 'E-mail already registered' };
}
} else {
ctx.status = 400;
ctx.body = { status: 'error', message: 'Invalid email or password' };
}
}
这是 authEmail() + GenerateToken 函数；
export function authEmail() {
return passport.authenticate('email');
}
/** After autentication using one of the strategies, generate a JWT token */
export function generateToken() {
return async ctx => {
console.log('generating token....')
console.log(ctx.passport)
const { user } = ctx.passport;
if (user === false) {
ctx.status = 401;
} else {
const _token = jwt.sign({id: user}, config.secret);
const token = `JWT ${_token}`;
const currentUser = await User.findOne({_id: user});
ctx.status = 200;
ctx.body = {
token,
user: currentUser,
};
}
};
}
最后是护照电子邮件策略：
import User from '../../models/user';
import { Strategy as CustomStrategy } from 'passport-custom';
export default new CustomStrategy(async(ctx, done) => {
console.log('Email Strategy: ', ctx.body);
try {
/** Test whether is a login using email and password */
if (ctx.body.email && ctx.body.password) {
const user = await User.findOne({ email: ctx.body.email.toLowerCase() });
if (!user) { done(null, false, {'message': 'User not found.'}); }
const password = ctx.body.password;
if (!user.validPassword(password))
return done(null, false, {'message': 'Password not correct.'});
done(null, user);
} else {
done(null, false, {'message': 'Email and Password are required.'});
}
} catch (error) {
done(error);
}
});
尝试向/auth/email我运行发布请求时出现以下错误；
生成令牌....
undefined
xxx POST /api/auth/email 500 124ms
TypeError: Cannot read property 'user' of undefined...
这是我第一次使用 koa 和 passport，所以我一直在尝试清理我找到的 github repo。（https://github.com/zombiQWERTY/koa2-starter-kit），代码主要改编自这里。
非常感谢您对问题的任何建议，如果您需要更多信息/希望我分享服务器代码的更多部分，请告诉我。
编辑：
这是堆栈跟踪：
