A client that follows redirects can be created as follows:
WebClient.builder()
.clientConnector(new ReactorClientHttpConnector(
HttpClient.create().followRedirect(true)
))
After invoking a HEAD request on a URL, how can the final Location header be retrieved? In other words, how can we get the final URL redirected to?
It is true that HttpClient#followRedirect(true) enables the redirection.
However there is also HttpClient#followRedirect(BiPredicate<HttpClientRequest,HttpClientResponse>), here you can control more precisely when you want to redirect and in addition to this you have always access to the response and the Location header, so in any time you will know to which location there will be a redirection.
More info here and here
For example
WebClient.builder()
.clientConnector(new ReactorClientHttpConnector(
HttpClient.create().followRedirect((req, res) -> {
System.out.println(res.responseHeaders().get("Location"));
return HttpResponseStatus.FOUND.equals(res.status());
})
))

I am trying to get URL which I am getting after redirection if do following:
cy.url().then(url => {
cy.log(url);
});
Then I get logged initial URL, but not the (new url), how do I get url in cypress after redirection?
redirection img (new url)
Solution:
To get the redirected URL just simply add cy.get and your element so it will wait until the redirect page loads. Here is the working solution for me:
cy.get('.crumb > p')
cy.url().then(url => {
cy.log(url);
});
Exactly as you wrote, you need to first wait for a element from the new URL to be visible, using a cy.get('any-element-from-the-new-url').
After that you can get the new URL just using cy.url(), in this case if you want to log this URL you can just use cy.log(cy.url()).
A more meaningful approach would be to add an assertion on the pathname to what you are expecting. The docs can shed some light on the cy.location(). You can use an include assertion on the pathname in the situation that you will not know all of the url string.
// visiting url - https://website.com/favorites
// redirects to - https://website.com/favorites/regional/local
cy.location('pathname') // yields "/favorites/regional/local"
.should('include', '/favorites/')
.then(cy.log)
If you do this, you don't have to do any previous step. Especially because the expectedUrl doesn't have to match the actual url which allow your test doesn't crash if that happens.
cy.url('match', 'expectedUrl').then(el=>{
cy.log(el)
})
I'm looking to 301 redirect to an external URL from within an Ember Route in Fastboot (based on the data returned by model()).
A solution, would be to access Express.js response object from within Ember, so I can call something like:
res.redirect(301, 'http://external-domain.com')?
However, I'm not entirely sure how res object can be accessed from within Ember.
Fastboot exposes a response object, but it's not the same as the Express res.
The following code will redirect both in Fastboot and in the browser:
if (this.get('fastboot.isFastBoot')) {
this.get('fastboot.response.headers').set('location', 'http://google.com');
this.set('fastboot.response.statusCode', 302);
} else {
window.location.replaceWith('http://google.com');
}
I'm trying to use a cloudflare worker to dynamically set the origin based on the requesting IP (so we can serve a testing version of the website internally)
I have this
addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request))
})
async function handleRequest(request) {
if (request.headers.get("cf-connecting-ip") == '185.X.X.X')
{
console.log('internal request change origin');
}
const response = await fetch(request)
console.log('Got response', response)
return response
}
I'm not sure what to set. The request object doesn't seem to have any suitable parameters to change.
Thanks
Normally, you should change the request's URL, like this:
// Parse the URL.
let url = new URL(request.url)
// Change the hostname.
url.hostname = "test-server.example.com"
// Construct a new request with the new URL
// and all other properties the same.
request = new Request(url, request)
Note that this will affect the Host header seen by the origin (it'll be test-server.example.com). Sometimes people want the Host header to remain the same. Cloudflare offers a non-standard extension to accomplish that:
// Tell Cloudflare to connect to `test-server.example.com`
// instead of the hostname specified in the URL.
request = new Request(request,
{cf: {resolveOverride: "test-server.example.com"}})
Note that for this to be allowed, test-server.example.com must be a hostname within your domain. However, you can of course configure that host to be a CNAME.
The resolveOverride feature is documented here: https://developers.cloudflare.com/workers/reference/apis/request/#the-cf-object
(The docs claim it is an "Enterprise only" feature, but this seems to be an error in the docs. Anyone can use this feature. I've filed a ticket to fix that...)
Am using a query param authentication with my backed that requires all http requests have the following
access-token=token
AM using vuejs2 resource
So in my request i want to intercept every request and attach the above so i have
Vue.http.interceptors.push(function (request, next) {
//here add the access token in my url string
//am stuck
next()
});
So i expect when i try
this.$http.get('users')
the request should automatically be
users?access-token=token
Also when ihave
this.$http.get('users?pagination=10')
then request url should have
users?pagination=10&access-token=token
How do i intercept all the requests and attach the query parameter access token
THe way i was able to resolve this was by
if(request.url.indexOf("?") === -1){ //means no access token since nothing is passed to the url
request.url = request.url+"?access-token=token";
}else{
if(request.url.indexOf("access-token") === -1){
request.url = request.url+"&access-token=token"
}
}
I am trying to redirect the user that uses my website after he has logged into his account, he will be redirected to a dashboard.
The problem is that I can see a request for the /dashboard route in the Network tab of the browser Inspection Tools, but the page never loads.
This is my code so far.
router.post('/login', function(request, response){
// verify against database and send back response
var userData = {};
userData.email = request.body.email;
userData.password = request.body.password;
userData.rememberPassword = request.body.rememberPassword;
// check if in the database and re-route
var query = database.query('SELECT * FROM users WHERE email = ?', [userData.email], function(error, result){
if(error){
console.log('Error ', error);
}
if(result.length){
// check if the password is correct
if(userData.password === result[0].password){
// redirect to the dashboard
// TODO this piece of code does not redirect correctly
response.redirect('/dashboard'); // < HERE
console.log('Haha');
}
}
else{
// do something when there is are no results
// invalid email status code
response.statusCode = 405;
response.send('');
}
});
});
And this is the route towards the dashboard, and it is being rendered properly when accessed in the browser.
router.get('/dashboard', function(request, response){
response.render(path.resolve(__dirname, 'views', 'dashboard.pug'));
});
Why can't it redirect when the user completes the login process?
Thanks.
The issue can be in the frontend and not in the backend. If you are using AJAX to send the POST request, it is specifically designed to not change your url.
Use window.location.href after AJAX's request has completed to update the URL with the desired path.But the easiest way would be to create a form with action as /login and use the submission to trigger the url change.
To make sure that the problem does not lie with the backend,
Add a logging statement to router.get('/dashboard' to verify if
the control was passed.
Check that the HTTP status code of the /login route is 302 indicating a redirect and location header has the route /dashboard.
Content type of response /dashboard is text/html.If not please set it using res.setHeader("Content-Type", "text/html").
