Lets say I have this route.
this.app.use('/app/fileasset/ui.html/:view*?', function(req,res) {});
If I have this url: /app/fileasset/ui.html /test/view
Then I can catch them in req.params ==> req.params[0] (root url, 'test') and req.params.view ('view')
The question is: how can I catch an unknown numbers of parameters ?
For example: /app/fileasset/ui.html /test/view/subview/wtv
How to get 'subview' and 'wtv' in req.params ? and having the same route to catch longer url with unknown number of params ?
thanks in advance
ExpressJS routing does allow to use wildcards, if you do something like this:
this.app.use('/app/fileasset/ui.html/*', function(req,res) {});
Then going to a url like /app/fileasset/ui.html/test/view/subview/wtv should populate req.params with "['test/view/subview/wtv']" which you can easily split on the forward slash.
Do you tryed foreach over req.params?
req.params.forEach(function (item) {
someFn(item);
})
or just for
for (var i = 0, len = req.params.length; i < len; i++) {
someFn(req.params[i]);
}

I want to get the number from the URL located in an API response.
For that I get the URL, but I don't know how to convert that in to text to extract the number.
cy.intercept('GET', 'http://viasphere.localhost/documents/page_elements/client/**',).as('response')
goTo.plusClientsButton()
cy.wait('#response', {timeout: 10000})
cy.get('#response').then( xhr => {
const link = xhr.request.headers.referer
cy.log(link)
link has the value: http://viasphere.localhost/documents/page_elements/client/19537
Obviosly const link = xhr.request.headers.referer.text() is not working...
You have to add .replace(/^\D+/g, '') to extract the number from the url.
cy.intercept(
'GET',
'http://viasphere.localhost/documents/page_elements/client/**'
).as('response')
goTo.plusClientsButton()
cy.wait('#response', {timeout: 10000})
cy.get('#response').then((xhr) => {
const client_id = xhr.request.headers.referer.replace(/^\D+/g, '')
cy.log(client_id) //prints 19537
})
Alternatively to the .then() Alapan Das provided, you can use cypress commands to perform the same actions.
cy.intercept('GET', 'http://viasphere.localhost/documents/page_elements/client/**',).as('response')
goTo.plusClientsButton()
cy.wait('#response', {timeout: 10000})
// can access request.headers.referer from .wait()
.its('request.headers.referer')
// returns 'http://viasphere.localhost/documents/page_elements/client/'
.invoke('replace', /^D+/g, '')
// now you have the link and can print it
.then(cy.log)
Trying to get variable from http://localhost:3000/categories/subcategories?category_id=13 but req.query returns empty result.
app.get('/subcategories', (req, res) => {
let category_id = req.query.category_id
console.log(req.query)
db.query('SELECT subcategory_name FROM subcategories WHERE category_id=(?)',
[category_id],
(err, result) =>{
res.send({category_id})
});
})
Is this possibly a problem with the way I've set up my server?
See how you are passing the data , directly entering the data or from another URL you are passing the data.
Ensuring you are not sending data via req.body. Ref :
Empty req.query on ExpressJS
or check res.send({category_id}) . Try printing res.send({"category_id": category_id}) . or see console.log(JSON.stringify(req.query))
Or Extract Query Parameters Without Express
const url = require('url');
const querystring = require('querystring');
let rawUrl = 'https://stackabuse.com/?page=2&limit=3';
let parsedUrl = url.parse(rawUrl);
let parsedQs = querystring.parse(parsedUrl.query);

I have to validate two fields are equals. In this case both passwords are the same. The problem it is that the "equals" from express-validator is not working.
This is the code:
app.post('/register', [
isNotLogged,
check('email', 'The email must be a valid one').isEmail(),
check('nickname', 'The nickname must be filled').notEmpty(),
check('password', 'The password must contain minimum eight characters, at least one letter and one number')
.matches("^(?=.*[A-Za-z])(?=.*\\d)[A-Za-z\\d]{8,}$"),
//This is not working
check('passwordConfirm', 'The passwords must match').equals('password'),
validateResults
], register)
Unfortunately Express-Validator doesn't work with Validator.js's equals(), you'll have to use one of Express-Validator's middlewares and not its Validator.js affility.
Here is an example straight from Express-Validator's website which seems fit your use case:
body('oldPassword')
// if the new password is provided...
.if((value, { req }) => req.body.newPassword)
// OR
.if(body('newPassword').exists())
// ...then the old password must be too...
.notEmpty()
// ...and they must not be equal.
.custom((value, { req }) => value !== req.body.newPassword);
You do not need to use Express-Validator's check middleware as you are throwing away your ability to utilise Validator.js's validators. Instead of check you could use isEmail() and exists() (an Express-Validator validator). Also, you don't need to have your middlewares as part of an array (although you can):
app.post('/register',
isNotLogged,
body('email').isEmail().withMessage('The email must be a valid one').bail().trim(),
body('nickname').exists({ checkNull: true }).withMessage('The nickname must be filled').bail().trim(),
body('password').trim().if((value, { req }) => (typeof req.body.passwordConfirm !== 'undefined')).bail().custom((value, { req }) => value !== req.body.passwordConfirm).withMessage('The email must be a valid one').bail().trim().matches("^(?=.*[A-Za-z])(?=.*\\d)[A-Za-z\\d]{8,}$"),
validateResults,
register
);
Here the body() function would come from const { body } = require('express-validator') theres a few others similar for query paramaters, header parameters ect, all are documented here.
I also used some trim()s and bails()s just to be safe. You can read up on those here and here.
I solve this problem like this:
code before:
const registrar = async (req, res) => {
await check('password').isLength({ min:6}).withMessage('password short ').run(req);
await check('repetir_password').equals('password').withMessage('password diferente?').run(req);
let resultado = validationResult(req);
res.json(resultado.array());
};
after:
correct code: change
'password'
by
req.body.password
const registrar = async (req, res) => {
await check('password').isLength({ min: 6 }).withMessage('password corta ').run(req);
await check('repetir_password').equals(req.body.password).withMessage('password diferente?').run(req);
let resultado = validationResult(req);
res.json(resultado.array());
};
I got one error with my blacklisted words, cannot read proprety ".id" of undefined. After "db.get(...)"
Thanks to help me!
// BLACKLISTED words
client.on('message', message => {
if(message.author.bot) return;
let wordarray = message.content.split(" ")
let filterWords = db.get(`blacklistwords_${message.guild.id}_${message.guild.id}`)
for(var i = 0; 1 < filterWords.length; i++) {
if(wordarray.includes(filterwords[i])) {
message.delete()
let Filter = new Discord.MessageEmbed()
.setColor('#FFE90F')
.setAuthor(message.guild.name, message.guild.iconURL())
.setDescription('<a:AttentionPink:706154679796760657> | **This word is blacklisted from this guild!** Do not say that again!')
.setTimestamp()
message.author.send(Filter)
break;
}
}
});
I think you should put your Guild ID in a var like so:
var guildID = message.guild.id;
If this is not working, well it's not the prettiest, but try using this line of code:
var guildID = bot.guilds.get(message.guild.id).id;
EDIT: Source
If the bot receives a message via DMs, it will not be able to get message.guild and that's why it says it is undefined. You can add something like if(message.channel.type === 'dm') return; so that the bot will not listen to DMs
How to rewrite all hash tag to slash tag under one directory? (apache)
http://www.domain.com/company/index#about => http://www.domain.com/company/index/about
http://www.domain.com/company/article#123456 => http://www.domain.com/company/article/123456
http://www.domain.com/company/events#October => http://www.domain.com/company/events/October
So, all the pages witch in /company/, rewrite # => /.
$(window).on('hashchange', function() {
//
}
In general all the browsers exclude the fragment part (#) from the request to the server. If you really want do it, you must rewrite the urls before call the server
function addHashtag2Pathname(url){
var a = document.createElement('a');
a.href = url;
if (a.pathname.substr(-1) != "/")
a.pathname = a.pathname + '/';
a.pathname += a.hash.replace(/^#/,'');
a.hash = '';
return a.href.replace(/#$/,'');
}
You can see this function in action here
http://jsfiddle.net/bknE4/43/
Actually I haven't tried this below, but it should work...
$(window).on('hashchange', function() {
var newurl = addHashtag2Pathname(location.href);
location.href = newurl;
})
If you navigate your web browser to http://www.domain.com/company/events#October, it will fetch the URL http://www.domain.com/company/events from the server. The server does not see the rest of the URL and can do nothing with it. Only Javascript can act on it.
$(window).on('hashchange', function() {
var a_tags = document.getElementsByTagName('a');
for (var i = 0; i < a_tags.length; i = i + 1) {
var elem = a_tags[i];
if (/company.*#/.test(elem.href)){
elem.href = elem.href.replace('#', '/');
}
}
}
You might want to change the regexp in the if conditional to be more specific.
The same for the replace function.
However I would change the HTML server side instead if it is supposed to be permanent.
