未經授權：錯誤401護照，智威湯遜

Question

passport.js

var jwtOptions = { 
     jwtFromRequest: ExtractJwt.fromAuthHeader(), 
     secretOrKey: config.secret 
    } 

    var jwtLogin = new JwtStrategy(jwtOptions, function (jwt_payload, done) { 
     console.log('payload received', jwt_payload); 
     User.findOne(jwt_payload._id, function (err, user) { 
      if (err) { 
      return done(err, false,{error:'its failed'}); 
     } 
     if (user) { 
      return done(null, user); 
     } 
     else { 
      done(null, false,{error:'401'}); 
     } 
    }); 
}); 

passport.use(jwtLogin); 

Authentication.js

function generateToken(user) { 
    return jwt.sign(user, key.secret, { 
     expiresIn: '1h', 
    }); 
}; 

function setUserInfo(request) { 
    console.log('inside setUserInfoo', request); 
    return { 
     _id: request._id, 
     email: request.email, 

    } 
}; 
exports.login = function (req, res, next) { 
    console.log('inside login function'); 
    var userInfo = setUserInfo(req.user); 
    res.status(200).json({ 
     token: generateToken(userInfo), //removed 'JWT' + generrateToken...Reading your answers. 
     user: userInfo 
    }); 
}; 

routes.js

//Assuming every thing is required correctly. 

var requireAuth = passport.authenticate('jwt',{session:false}); 

app.use('/api/contacts', contactRoutes); 

    contactRoutes.get('/',requireAuth, function(req,res){ 
     console.log('inside get route of contacts'); 
     contactControllers.getContacts(req,res)}); 

    contactRoutes.post('/', requireAuth, function (req, res) { 
     console.log("inside post routes of contacts"); 
     contactControllers.postContacts(req, res); //logic is correct but generate token syntax is similar to login function one. 
    }); 

服務類 .ts

獲取數據。

getContacts() { 
    console.log('Inside getContacts() of service class'); 
    return new Promise((resolve, reject) => { 
     let headers = new Headers(); 
     headers.append('Authorization', this.auth.token); 
     console.log('inside promise'); 

     this.http.get('http://localhost:8080/api/contacts/', { headers: headers }).map(res => 
     res.json()) 
     .subscribe(data => { 
      resolve(data); 
      console.log('inside resolve of service class', data); 
     }, 
     (err) => { 
      reject(err); 
     }); 
    }); 
    } 

我不使用授權這裏

，只有Authentication.When調用從服務類get後它會顯示unauthorized.Please幫助。

在Authentication.js文件中，我已經使用了Token：跟隨你的ans到了一些帖子，我已經刪除了'JWT'。但是那時也會顯示401未經授權的錯誤。

請幫忙！

Answer 1

在你headers.append（）位於你的服務文件的要求授權，交換機，認證和看看是否能工程

Answer 2

headers.append('Authorization', 'JWT ' + this.auth.token); 

Answer 3

可以代替試試這個：

headers.append('Authorization', 'Bearer ${this.auth.token}');
