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/学习了教程。 但是我在这部分有错误
passport.use(new JwtStrategy(opts, function(jwt_payload, done)
这是我运行节点“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) at new JwtStrategy (/home/chibi/Documents/connect/project/node_modules/passport-jwt/lib/strategy.js:39:15) at module.exports (/home/chibi/Documents/connect/project/config/passport.js:10:16) at Object.<anonymous> (/home/chibi/Documents/connect/project/server.js:30:29) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Function.Module.runMain (module.js:497:10) at startup (node.js:119:16) at node.js:902:3
解决办法是什么?
我认为你正在使用'passport-jwt'2.0.0,它已经添加了一些来自教程使用的v1.xx的重大更改。 在opts
你需要传递另一个选项jwtFromRequest
告诉它在哪里寻找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 } }); }));
从官方文档中 ,使用JWT从2.x迁移到3.x时,应该使用:
ExtractJwt.fromAuthHeaderWithScheme('jwt')
而不是旧的:
ExtractJwt.fromAuthHeader()
