`express` - app chrome 邮递员总是给出错误而不是响应

Question

请有人帮我找到这里的问题：

当我尝试 post 我的 username 和 password 时，我总是收到错误消息： requester.js:6211 POST http://localhost:7000/api/login 403 (Forbidden)send @ requester.js:6211(anonymous function) @ requester.js:4811dispatch @ jquery.min.js:3i @ jquery.min.js:3 requester.js:1056 Defining mode

我完全不知道这里的问题是什么。这是 post 人工请求的屏幕截图：

这是我的 api 文件：

var User = require('../models/user');
var config = require('../../config');

var secretKey = config.secretKey;

var jsonwebtoken = require("jsonwebtoken");


function createToken ( user ) {

    var token = jsonwebtoken.sign({
        _id : user.id,
        name : user.name,
        username: user.username
    }, secretKey, {
        expiresIn  : "1440m"
    })

    return token;
}

module.exports = function( app, express ) {

    var api = express.Router();

    api.post('/signup', function( req, res ) {

        var user = new User({
            name : req.body.name,
            username : req.body.username,
            password : req.body.password
        });

        user.save( function( err ) {
            if( err ) {

                res.send( err );
                return;

            }

            res.json({message : "User has been created!"});
        });

        api.get('/users', function( req, res ) {

            User.find({}, function( err, users ) {

                if( err ) {
                    res.send( err );
                    return;
                }

                res.json( users );

            })

        });

        api.post('/login', function( req, res ) {

            User.findOne({
                username : req.body.username
            }).select('password').exec(function( err, user ) {

                if( err ) throw err;

                if(!user) {
                    res.send({ message : "User doesnt Exist!"})
                } else if( user ) {

                    var validPassword = user.comparePassword( req.body.password );

                    if(!validPassword) {
                        res.send({ message : "Invalid Password"});
                    } else {

                        var token = createToken( user );

                        res.json({
                            success : true,
                            message : "Successfuly loged In!",
                            token : token
                        })

                    }
                }

            })

        })

    });

    //middleware

    api.use(function(req, res, next) {


        console.log("Somebody just came to our app!");

        var token = req.body.token || req.param('token') || req.headers['x-access-token'];

        // check if token exist
        if(token) {

            jsonwebtoken.verify(token, secretKey, function(err, decoded) {

                if(err) {
                    res.status(403).send({ success: false, message: "Failed to authenticate user"});

                } else {
                    req.decoded = decoded;
                    next();
                }
            });
        } else {
            res.status(403).send({ success: false, message: "No Token Provided"});
        }

    });

    //Destination B

    api.get("/", function( req, res ) {

        res.json("Hello World!");

    })

    return api;

}

Answer 1

路由应该是 'api/signup' 而不仅仅是 '/signup'。

路由定义不正确。而不是：

 api.post('/signup', function( req, res ) {
...
        api.get('/users', function( req, res ) {
   })
})

应该是：

 api.post('/signup', function( req, res ) {
...
})
api.get('/users', function( req, res ) {
...
})
