I have a problem escaping a Url validation of Token . I am using lib jwt (jsonwebtoken) to restrict the access to request of my api, however I want to leave url /imagem/:parametro without validation by token. Because today when I make the following request /imagem/teste.png it does not let pass without the token.
I'm doing it this way:
My server.js
const express = require('express');
const app = express();
const consign = require('consign');
const bodyParser = require('body-parser');
const fileupload = require('express-fileupload');
const jwt = require('jsonwebtoken');
module.exports = function(){
//define a url para arquivos estáticos
app.use('/public', express.static('./app/public'));
//habilta request e response json
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
//habilita o middleware de upload
app.use(fileupload());
//verifica se o token é valido
app.use(function(request, response, next){
if(request.originalUrl == '/token' || request.originalUrl == '/login' || request.originalUrl == '/imagem/' ){
return next();
}else{
if (request.headers.authorization && request.headers.authorization.split(' ')[0] === 'Bearer') {
var token = request.headers.authorization.split(' ')[1];
jwt.verify(token, process.env.SECRET_KEY, function(err, decoded) {
if (err) return response.status(500).send({ auth: false, message: 'Falha ao autenticar o token.' });
request.userId = decoded.id;
next();
});
} else if (request.query && request.query.token) {
next();
return request.query.token;
}else{
response.json("Não Autorizado!");
next();
}
}
});
app.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
});
//carrega modulos na variavel "app"
consign({ cwd: 'app' }).include('routes').then('controllers').then('helpers').into(app);
return app;
}
My Image Route
module.exports = function(app) {
app.get('/imagem/:nome', function(request, response, next){
var path = require("path");
var nome_imagem = request.params.nome;
response.sendFile(path.resolve('app', 'public', '${nome_imagem}') );
});
app.post('/imagem', function(request, response, next){
var file = request.files.img;
var extensao = file.name.slice('.');
var nome_arquivo = 'img-' + Date.now() + '.' + extensao;
file.mv('app/public/${nome_arquivo}', function(err){
if(err){
return response.status(500).send(err);
}
})
});
}
Note: I'm using express: 4.16.4 and lib jsonwebtoken: 8.3.0
