NodeJs-从JWT令牌中检索用户信息?
节点和角度。我有一个MEAN堆栈身份验证应用程序,在其中按如下所述在成功登录时设置JWT令牌,并将其存储在控制器的会话中。通过服务拦截器将JWT令牌分配给config.headers:
var token = jwt.sign({id: user._id}, secret.secretToken, { expiresIn: tokenManager.TOKEN_EXPIRATION_SEC }); return res.json({token:token});
authservice.js Interceptor(省略了requestError,response和responseError):
authServices.factory('TokenInterceptor', ['$q', '$window', '$location','AuthenticationService',function ($q, $window, $location, AuthenticationService) { return {
request: function (config) {
config.headers = config.headers || {};
if ($window.sessionStorage.token) {
config.headers.Authorization = 'Bearer ' + $window.sessionStorage.token;
}
return config;
}
};
}]);
现在我想从令牌中获取登录的用户详细信息,我该怎么做?我尝试如下,但无法正常工作。当我记录来自Users.js文件的错误时,它的意思是“
ReferenceError:未定义标头”
authController.js:
$scope.me = function() { UserService.me(function(res) {
$scope.myDetails = res;
}, function() {
console.log('Failed to fetch details');
$rootScope.error = 'Failed to fetch details';
})
};
authService.js:
authServices.factory('UserService',['$http', function($http) { return {
me:function() {
return $http.get(options.api.base_url + '/me');
}
}
}]);
Users.js(节点):
exports.me = function(req,res){ if (req.headers && req.headers.authorization) {
var authorization =req.headers.authorization;
var part = authorization.split(' ');
//logic here to retrieve the user from database
}
return res.send(200);
}
为了检索用户详细信息,我是否也必须将令牌作为参数传递?还是将用户详细信息保存在单独的会话变量中?
回答:
首先,将Passport中间件用于用户授权处理是一个好习惯。它需要解析您的请求的所有繁琐工作,还提供许多授权选项。现在为您的Node.js代码。您需要使用jwt方法验证并解析传递的令牌,然后通过从令牌中提取的ID查找用户:
exports.me = function(req,res){ if (req.headers && req.headers.authorization) {
var authorization = req.headers.authorization.split(' ')[1],
decoded;
try {
decoded = jwt.verify(authorization, secret.secretToken);
} catch (e) {
return res.status(401).send('unauthorized');
}
var userId = decoded.id;
// Fetch the user by id
User.findOne({_id: userId}).then(function(user){
// Do something with the user
return res.send(200);
});
}
return res.send(500);
}
