node.js – NodeJS jwtStrategy需要一个函数来从请求错误中检索jwt

我从 https://devdactic.com/restful-api-user-authentication-1/学习教程.但是我在这方面有错误

passport.use(new JwtStrategy(opts, function(jwt_payload, done)

这是运行节点“server.js”时的错误

/home/chibi/Documents/connect/project/node_modules/passport-jwt/lib/strategy.js:39
throw new TypeError('JwtStrategy requires a function to retrieve jwt f
          ^
TypeError: JwtStrategy requires a function to retrieve jwt from requests (see option jwtFromRequest)

解决办法是什么?

我认为你正在使用’passport-jwt’2.0.0,它已添加了本教程使用的v1.x.x中的一些突破性更改.在选择中,您需要传递另一个选项jwtFromRequest来告诉它在哪里查找jwt有效载荷.

var JwtStrategy = require('passport-jwt').Strategy,
    ExtractJwt = require('passport-jwt').ExtractJwt;
var opts = {};
opts.jwtFromRequest = ExtractJwt.fromAuthHeader();
opts.secretOrKey = config.secret;
passport.use(new JwtStrategy(opts, function(jwt_payload, done) {
    User.findOne({id: jwt_payload.id}, function(err, user) {
        if (err) {
            return done(err, false);
        }
        if (user) {
            done(null, user);
        } else {
            done(null, false);
            // or you could create a new account
        }
    });
}));
