嗨,我正在尝试使用通行证js和jsonwebtoken进行我的android应用程序的身份验证,但是当我尝试生成令牌作为用户登录名并使用邮递员测试api时,响应错误:

router.get('/login', user.isLoggedOut);
//AUTH routes
router.post('/registration', user.userRegister);

//Update User and delete User code below
这是provider.js文件:
const config = require('../config.js'); //ket noi db
const jwt = require('jsonwebtoken');
module.exports.deletePropertyOBject = function(myObject, property) {
var obj = myObject;
delete obj[property];
// console.log(obj);
return obj;
}
module.exports.setDataReturn = function(status = '', message = '', data = {}) {
*// const token = jwt.sign(data, 'superSecret', { expiresIn: config.tokenTime });*
IF I UNCOMMENTED THIS IT WOULD REPORT THE ERROR
var objReturn = {
"success": status,
"message": message,
'data': data,
};
return objReturn;
}
module.exports.createToken = function(user) {
var token = jwt.sign(user, 'superSecret', { expiresIn: config.tokenTime });
return token;
}
//xac thuc token
module.exports.verifyToken = function(req, res, next) {
next();
// var bearerHeader = req.headers['authorization'];;
// if (typeof(bearerHeader) !== 'undefined') {
// var bearer = bearerHeader.split(' ');
// var bearerToken = bearer[0];
// jwt.verify(bearerToken, 'superSecret', function(err, authData) {
// if (err) {
// res.sendStatus(403);
// } else {
// next();
// }
// });
// } else {
// res.sendStatus(403);
// }
}
module.exports.validateParam = function(obj) {
var output = {
status: true,
message: []
};
for (let [key, value] of Object.entries(obj)) {
if (typeof value === "undefined") {
output.message.push(key);
output.status = false;
}
}
return output;
}
谢谢您的帮助!

req.user是一个猫鼬对象,因此当在jwt.sign()中使用它时,显然会引起问题,我们必须将该对象转换为json,用use.toJSON(替换jwt.sign(user)中的用户)。这样可以解决问题
