我创建了一个api，引用了这个link 它以下列方式验证请求：
router.post('/authenticate', function(req, res) {
var query = "SELECT * FROM ?? WHERE ??=? and ??=? LIMIT 1";
var table = ["users","user_email",req.body.user_email, "user_password",md5(req.body.user_password)];
query = mysql.format(query,table);
connection.query(query,function(err,rows){
if(err) {
res.json({"Error" : true, "Message" : "Error executing MySQL query"});
} else {
if(rows.length > 0){
var user = {'user_email':rows.user_email, 'user_password':rows.user_password}
var token = jwt.sign(user, app.get('superSecret'), {
expiresIn: '24h' // expires in 24 hours
});
delete rows[0].user_password;
// return the information including token as JSON
res.status(200).json({
error: false,
message: 'success',
token: token,
user:rows
});
} else {
res.status(404).json({"Error" : true, "Message" : "No records found"});
}
}
});
});
router.post("/users",function(req,res){
req.checkBody({
'user_email': {
notEmpty: true,
isEmail: {
errorMessage: 'Invalid Email'
}
},
'user_password': {
notEmpty: true,
isLength: {
options: [{ min: 6, max: 10 }],
errorMessage: 'Password must be between 6 and 10 chars long' // Error message for the validator, takes precedent over parameter message
},
errorMessage: 'Invalid Password' // Error message for the parameter
},
'user_name': { //
notEmpty: true, // won't validate if field is empty
isLength: {
options: [{ min: 2, max: 10 }],
errorMessage: 'Must be between 2 and 10 chars long' // Error message for the validator, takes precedent over parameter message
},
errorMessage: 'Invalid User Name'
},
'phone_number': { //
notEmpty: true,
isLength: {
options: [{ min: 10, max: 15}],
errorMessage: 'Must be between 10 and 15 chars long' // Error message for the validator, takes precedent over parameter message
},
errorMessage: 'Invalid Phone Number'
},
'address': { //
notEmpty: true,
isLength: {
options: [{ min: 10, max: 100}],
errorMessage: 'Must be between 10 and 100 chars long' // Error message for the validator, takes precedent over parameter message
},
errorMessage: 'Invalid Address'
},
'device_type': { //
notEmpty: true,
errorMessage: 'Invalid device type'
},
'login_type': { //
notEmpty: true,
errorMessage: 'Invalid login type'
},
'gcm_user_id': { //
notEmpty: true,
errorMessage: 'Invalid gcm id'
}
});
var errors = req.validationErrors();
if (errors) {
res.status(500).json(errors);
return;
}
var query = "INSERT INTO ??(??,??,??,??,??,??,??,??) VALUES (?,?,?,?,?,?,?,?)";
var table = ["users","user_name", "user_email", "user_password", "phone_number", "address", "device_type", "login_type", "gcm_user_id",
req.body.user_name, req.body.user_email, md5(req.body.user_password), req.body.phone_number, req.body.address,
req.body.device_type, req.body.login_type,req.body.gcm_user_id];
query = mysql.format(query,table);
connection.query(query,function(err,record){
if(err) {
res.status(500).json({"Error" : true, "Message" : err.message});
} else {
var query = "select * from ?? WHERE ?? = ?";
var table = ["users", "id", record.insertId];
query = mysql.format(query,table);
connection.query(query,function(err,rows){
if(err) throw err;
res.status(200).json({"Error" : false, "message" : "User Added !", "data":rows});
});
}
});
});
// route middleware to verify a token
router.use(function(req, res, next) {
// check header or url parameters or post parameters for token
var token = req.headers['x-access-token'];
console.log(token,'token');
// decode token
if (token) {
// verifies secret and checks exp
jwt.verify(token, app.get('superSecret'), function(err, decoded) {
if (err) {
console.log(err);
return res.json({ success: false, message: 'Failed to authenticate token.' });
} else {
// if everything is good, save to request for use in other routes
req.decoded = decoded;
next();
}
});
} else {
// if there is no token
// return an error
return res.status(401).send({
success: false,
message: 'No token provided.'
});
}
});
我想以下列方式验证请求：
实施例：
router.get("/users", jwtValidate ,function(req,res)
目前为避免身份验证，我必须在中间件上方应用路由。
答案 0 :(得分：4)
您可以通过以下方式验证请求：
router.get("/users", router.jwtValidate ,function(req,res){
//logic here
});
/**
* Require Mobile Login Routing middleware
* This function check if user loggedIn from mobile then verify it's Token.
* Here we implement middleware of mobile Auth
*/
router.jwtValidate = function(req, res, next) {
var token;
if (req.headers && req.headers.authorization) {
var parts = req.headers.authorization.split(' ');
if (parts.length == 2) {
var scheme = parts[0],
credentials = parts[1];
if (/^Bearer$/i.test(scheme)) {
token = credentials;
}
} else {
return res.json(401, {message: 'Format is Authorization: Bearer [token]'});
}
} else if (req.param('token')) {
token = req.param('token');
// We delete the token from query and body to not mess with blueprints
delete req.query.token;
delete req.body.token;
} else {
return res.status(401).send({
message: 'No Authorization header was found'
});
}
tokenService.verifyToken(token, function (error, token) {
if (error) {
return res.json(401, {message: 'User is not logged in'});
} else {
req.token = token;
req.user = token;
return next();
}
});
}
对于令牌服务，您可以使用以下代码：
/**
* jwt token service
*/
var jwt = require('jsonwebtoken');
var config = require('config');
// With this method we generate a new token based on payload we want to put on it
module.exports.issueToken = function(payload) {
return jwt.sign(
payload, // This is the payload we want to put inside the token
'config.secret' // Secret string which will be used to sign the token
);
};
// Here we verify that the token we received on a request hasn't be tampered with.
module.exports.verifyToken = function(token, verified) {
if(token && verified) {
return jwt.verify(
token, // The token to be verified
'config.secret', // The secret we used to sign it.
{}, // Options, none in this case
verified // The callback to be call when the verification is done.
);
}
};
