5 years ago Cloudflare is a service to mitigate servers from getting taken down from a DDoS. I don't know if this is going to be a permanent move from GGG, if that is the case we will have to put some very significant changes into Procurement.
If, as the league progresses, they move their endpoint from behind cloudflare. Procurement will carry on working. I will do my best to see if there is anything that can be done to restore procurement to a working state in the meantime but I would like to stress that getting around cloudflare will not be easy at all.

5 years ago This indeed appears to be problematic.
From what I've been able to figure out so far, the purpose of the Cloudflare DDoS protection splash screen (which you sometimes see when going to a Cloudflare-protected site) is designed so the browser performs some Javascript computation and sends it back to Cloudflare, "proving" it's not a bot or something like that. You can see some more details in this blog post; it looks like the computation that was required in the past was a simple Javascript mathematical expression, but it's since been obfuscated; when I went to pathofexile.com and looked at the source code of the CloudFlare page I got something like:
(function(){
var a = function() {try{return !!window.addEventListener} catch(e) {return !1} },
b = function(b, c) {a() ? document.addEventListener("DOMContentLoaded", b, c) : document.attachEvent("onreadystatechange", b)};
b(function(){
var a = document.getElementById('cf-content');a.style.display = 'block';
setTimeout(function(){
var s,t,o,p,b,r,e,a,k,i,n,g,f, UtFxZSV={"Q":+((!+[]+!![]+!![]+!![]+!![]+!![]+!![]+[])+(!+[]+!![]+!![]+!![]+!![]+!![]+!![]+!![]+!![])+(!+[]+!![]+!![]+!![]+!![]+!![]+!![])+(+[])+(+[])+(!+[]+!![]+!![])+(!+[]+!![]+!![]+!![])+(!+[]+!![]+!![])+(!+[]+!![]+!![]+!![]+!![]+!![]+!![]))/+((!+[]+!![]+!![]+[])+(!+[]+!![]+!![]+!![]+!![])+(!+[]+!![])+(!+[]+!![])+(!+[]+!![])+(!+[]+!![]+!![]+!![]+!![]+!![]+!![])+(!+[]+!![]+!![])+(!+[]+!![]+!![]+!![]+!![]+!![]+!![]+!![]+!![])+(!+[]+!![]+!![]+!![]))};
t = document.createElement('div');
t.innerHTML="<a href='/'>x</a>";
t = t.firstChild.href;r = t.match(/https?:\/\//)[0];
t = t.substr(r.length); t = t.substr(0,t.length-1);
a = document.getElementById('jschl-answer');
f = document.getElementById('challenge-form');
;UtFxZSV.Q-=+((!+[]+!![]+!![]+!![]+!![]+!![]+!![]+!![]+[])+(+!![])+(!+[]+!![]+!![]+!![]+!![]+!![]+!![])+(!+[]+!![]+!![]+!![]+!![])+(+[])+(!+[]+!![]+!![]+!![])+(!+[]+!![])+(!+[]+!![]+!![]+!![])+(!+[]+!![]+!![]))/+((+!![]+[])+(!+[]+!![]+!![]+!![]+!![]+!![])+(+!![])+(+!![])+(!+[]+!![]+!![]+!![]+!![]+!![]+!![]+!![]+!![])+(!+[]+!![]+!![]+!![]+!![])+(!+[]+!![]+!![]+!![]+!![])+(!+[]+!![]+!![]+!![]+!![]+!![])+(!+[]+!![]+!![]+!![]+!![]+!![]+!![]+!![]+!![]));a.value = +UtFxZSV.Q.toFixed(10) + t.length; '; 121'
f.action += location.hash;
f.submit();
}, 4000);
}, false);
})();We'll need to tackle this in different ways for each of the login methods we provide.
Right now, when Procurement makes a web request, such as to https://www.pathofexile.com/login to log in, it does not execute any Javascript, as that is complicated and unnecessary for our needs thus far. It's plausible we can use something like this CloudFlareUtilities library (available as a NuGet package), which uses pure C# to perform the necessary computations for CloudFlare, and manage any CloudFlare cookies. However, there are some complications.
HttpClient, which we do not use, so it is not a drop-in replacement or trivial addition to our code. In theory, however, the infrastructure we use is deprecated and, according to the .NET documentation, we should use HttpClient instead anyway.The CloudFlare DDoS protection works, in part, by keeping track of a client's user-agent and several cookies. Right now when the Procurement user logs in via Session ID we require the him to first log in to pathofexile.com and dig around in the cookies for the POESESSID. Beyond requiring this, we would also need the user to supply:
There is a description of this process here, with screenshots.
As that link reveals, there have been other Path of Exile apps which have faced similar issues. The situation in that link was when poe.trade started using CloudFlare. We might be able to learn some techniques from what they or others have done, but I really hope will be able to delegate handling the CloudFlare DDoS page to an external dependency, so we aren't required to keep updating it whenever CloudFlare changes their algorithm.
Of course, the best solution is for GGG to provide an actual login endpoint for their API so we don't need to rely on screen-scraping the login response, but it's not like it's Christmas or anything. Or maybe they could use OAuth or something like what EVE Online has/had.

5 years ago @qwak-adikt, I'm curious who you're referring to by "they". 👼
I created a pull request that is a quick-and-dirty way of logging in using Session ID. As mentioned in my earlier comment, it requires the user to provide three additional pieces of information when logging in, and I'm afraid one of the CloudFlare cookies could invalidate automatically after an hour or so, forcing the user to get a new one in his browser and logging back in to Procurement for it to be able to fetch data again.

5 years ago Actually if only the login endpoint is behind CloudFlare, then it might not matter while Procurement is running if that cookie expires, since we don't use the login endpoint except when logging in.

commented
5 years ago have you guys also checked this? https://github.com/elcattivo/CloudFlareUtilities perhaps will eliminate the needing for cookies from the browser (I did a few tests yesterday locally and I could authenticate with it, didn't had much time though to test further)
Yes - I was looking at using this myself yesterday, I have mentioned it to @thailyn in his pr #902
Just letting people know I have tested #902 myself locally and it will close #901
Round of applause for @thailyn

5 years ago Procurement 1.24.1 has been released, which fixes this issue when using SessionID
All credit to @aydjay and @thailyn for their work on getting this solved quickly.
Just downloaded the app and I cant login , no matter what I try
