Best HTTP Released

It doesn't work in editor mode. I send http request and not become response.

 

@mcmorry

When the request is aborted the the plugin will close the tcp connection and various errors will arise. These will be caught by the plugin, but some logging still occur however. All, in all these are harmless if you abort the request and you can ignore them.

IsKeepAlive: Open connections will consume server resources, but the plugin will close them quite quickly (20 sec) if there's no new request to send out. There's no direct way to close these open connections, however you can lower the default 20 sec to your needs:

Code (CSharp):

1. HTTPManager.MaxConnectionIdleTime = TimeSpan.FromSeconds(5);

 

@MaByteSolution

Can you share what you tried and what was you Unity version?
This code just worked right now with Unity 2017.2:

Code (CSharp):

1. using System;
2.  
3. using UnityEngine;
4. using UnityEditor;
5.  
6. using BestHTTP;
7.  
8. public class EditorTest : EditorWindow {
9.     [MenuItem("Window/Editor Test")]
10.     public static void Init() {
11.         EditorWindow.GetWindow(typeof(EditorTest));
12.     }
13.  
14.     void OnGUI() {
15.         if (GUILayout.Button("Send Request"))
16.             new HTTPRequest(new Uri("http://httpbin.org/get"), (req, resp) => Debug.Log(resp.DataAsText)).Send();
17.     }
18. }

 

@BestHTTP
Thank, it's ok. This was my mistake.

 

Hi, you have a way to add a cookie, but is there a way to remove a cookie that I dont want to send anymore?
This "add cookie" code is working:

Code (CSharp):

1. var request = new HTTPRequest(new Uri(address), OnFinished);
2. request.Cookies.Add(new Cookie("Name", "Value"));
3. request.Send();

This "remove cookie" code is not working (c is always null whereas the cookie "csrftoken" is still sent):

Code (CSharp):

1. HTTPRequest r = new HTTPRequest(new Uri(Url),
2.     HTTPMethods.Get, /* HTTPMethods methodType */
3.     true, true,  /* bool isKeepAlive, bool disableCache */
4.     GetFinished);
5. Cookie c = r.Cookies.Find(e => e.Name == "csrftoken");
6. if (c != null) {
7.     r.Cookies.Remove(c);
8. }
9. r.Send();

I've looked at your code, and you can't modify MaxAge (public long MaxAge { get; private set; })
To remove a cookie we could set its MaxAge to 0 (see here)

Maybe you have another solution that could suit me: add a custom filter to SetCookie that ignores specific cookies...

 

I've been struggling with this problem for 16 hours now, and it drives me nuts.
I've made a Unity client that uses Best HTTP Pro, for my Django Web application.
I've generated the .exe file. When I double click to launch the program, many times to try:
- the first client, let's call it "client A", fetches an URL / GET method, and in that URL, Django sends back "Set cookie" with sessionid = (value1)
- then the client A fetches an URL / POST method + user and password to login, Django says it's ok
- the second client, let's call it "client B", fetches an URL / GET method, and... there the cookie of the session of the first client!

I thought that the first "GET" call of the client B should not know have any cookies and should not send any cookie, right? This is the first "GET". But Wireshark showed me that the client B did already have the cookie of the client A! What am I missing here? Is there memory sharing between the two executables running, or whatever in Windows?

 

@OlivierPons

Cookies: The response's cookies contains the cookies that came from the server, but it's just a list of them. There a CookieJar that manages all of the cookies. If you want to delete a cookie to do not send back to the server, you have to delete it from the CookieJar.

You can use the Remove function to remove one cookie:

Code (CSharp):

1. BestHTTP.Cookies.CookieJar.Remove(uri, "cookie_key");

You can clear all stored cookies:

Code (CSharp):

1. BestHTTP.Cookies.CookieJar.Clear();

Or all cookies for a given domain:

Code (CSharp):

1. BestHTTP.Cookies.CookieJar.Clear("example.com");

On your second problem: It's quite expected. The plugin stores the cookies in the folder return by the Application.persistentDataPath. It constructs the path using the CompanyName + Product Name of your app. Because you built one app and executed (at least) two instances, they read from and saved to the very same file.

So, client A received sessionId from the server and saved cookies to the \CompanyName\ProductName\Cookies folder. Client B will load the CookiJar from the very same \CompanyName\ProductName\Cookies folder that contains the sessionId from client A, so when you initiate a request to the server it will load up the sessionId that client A received.

 

Thank you very much for your good and professional answer! You could copy / paste your nice previous answer to a FAQ addedum in your documentation

So my solution: to launch + test many times the same program, when the user logs in I set the cookie folder as "Cookies/[username]":

Code (CSharp):

1.         string p = Path.Combine(Application.persistentDataPath, "Cookies/");
2.         HTTPManager.RootCacheFolderProvider =
3.             () => Path.Combine(p, login);

Do you think it's ok, or there's a better suggestion/practice?

 

@OlivierPons

You can define your custom folder provider, so with a clever algorithm, you can generate different paths for each application instance.

The following is a quite simple example, it will assign a random path for each run (untested). Its drawback is that persistent caching became meaningless, as the next run it will generate a new path. Although it might give you a good headstart.

Code (CSharp):

1. BestHTTP.HTTPManager.RootCacheFolderProvider = () => System.IO.Path.Combine(Application.persistentDataPath, UnityEngine.Random.Range(0, int.MaxValue).ToString());

A better solution would be to be able to configure from the command line, or an ingame console, etc.

You should set the RootCacheFolderProvider in your startup code before any interaction with the plugin (eg. sending out requests, or starting other protocols).

 

@OlivierPons

As I see while I wrote my answer you already found the RootCacheProvider.

The problem with your solution is that folders are cached by the various subsystems (cache and cookie jar), so even if you change what path it returns, it will have no effect.

You have one option that i can see, that you have to generate a unique path when your app starts.

 

Hi,
I have problem with my Best HTTP basic edition.

Code (CSharp):

1. void Start() {
2.         SocketOptions options = new SocketOptions();
3.         options.AutoConnect = false;
4.         socketManager = new SocketManager(new Uri("http://192.168.0.129:3000/socket.io/"), options);
5.  
6.         socket = socketManager.Socket;
7.         socketManager.Socket.On(ResponseEventEnum.ERROR, OnError);
8.         socketManager.Socket.On(ResponseEventEnum.REGISTER_COMPLETED, OnRegisterCompleted);
9.         socketManager.Socket.On(ResponseEventEnum.LOGIN_SUCCESSFUL, OnLoginSuccessful);
10.         socketManager.Socket.On(ResponseEventEnum.ENTERED_TO_WORLD, OnEnteredToWorld);
11.         socketManager.Socket.On(ResponseEventEnum.USER_CONNECTED, OnUserConnected);
12.         socketManager.Socket.On(ResponseEventEnum.PLAYER_DISCONNECTED, OnPlayerDisconnecteda);
13. }

And event after button clicked:

Code (CSharp):

1. void MainMenuView_OnStartGameButtonClicked(MainMenuView mainMenuView) {
2.         socketManager.Open();
3.         mainMenuView.Hide();
4.        
5.     }

I receive following errors when I click the StartButton.

and

Version of Unity: 2017.3.0f3
Version of Best HTTP: 1.10.3


and

 

I don't know why but I can't add those two screens. So I wrote second post.

Maybe it has some connection with the following settings?
After first import I had another error message that tells

So I changed the settings as follow (screenshots).

 

@w4der

You should try to restart Unity.

No kidding, when Unity 2017.3 released it did the same to me, but restarting Unity solved it.

Anyway, your import settings are good now.

 

Hi,
I still have those two errors (I wrote about them 2 posts ago, I think you didin't see it).
Do you have any idea what is going wrong?
Above you can find the code.

and

 

@w4der

As I wrote this was the same to me too. For some unknown reason, Unity couldn't recognize the HTTPUpdateDelegator class as a derived class of MonoBehaviour. I can reproduce this easily by deleting my project's Library folder, then opening it in Unity 2017.3. But, closing Unity then opening the project again it works correctly...

After deleting Library folder:


Just closed Unity and opened again the very same project:

 

Thank you for your reply! Problem solved <3

I have second question.
Is the communication between client -> server somehow encrypted / protected against other?

If no... could you please tell any good solution that you recommend?

i.e. I have

Code (CSharp):

1. // Send a custom event to the server with two parameters
2. manager.Socket.Emit("LOGIN", "userName", "password");

 

@w4der

Communication isn't encrypted, but you can and should choose HTTPS to encrypt the whole communication.

 

Hi @BestHTTP , I'm wondering how can I implement the bypass cloudflare anti ddos just like this package in nodejs https://www.npmjs.com/package/cloudscraper
My full scenario is:
1/ Open httprequest to server
2/ Server then return a cloudflare anti ddos page
3/ By pass this page just like what cloudscraper does
4/ Then access to the main page and open websocket or signalR connection to the server.

For now I get stuck at step 3, would be great if you can suggest any solution for this.
Thanks.

 

@emperor1412

If you check out the source of cloudscraper, you can see that it intercepts the responses and if it contains a 'challange' it tries to solve it and will send back the answer. If it gave the right answers, it's able to initiate a request to the original address now.

It can be done with the plugin, the real challenge is the challenge itself.

 

@BestHTTP
Hi, How to force close websocket on webgl platform？
Other platforms I can call “Implementation.InternalRequest.Abort ()”

 

@melefans

Under WebGL you can use the regular websocket's Close() function only.

 

@BestHTTP I'm having an issue getting a JSON array back as HTTPRequest only returns the first element of the array.

When I plug the URL+args into the Unity WWW class it returns all elements of the array which is what I expected.

Can you think why this might be at all?

thanks

Nalin

 

@puzzlekings

It's usually when the server doesn't send a Content-Length header so the plugin can't know how much data it has to download. It will try as much as it can, but there's a high chance that it will not read all of them.
You can use a proxy or you can set the plugin's log level to All so it will log out all received headers so you can search for a Content-Length header. If there's no such header (or a Transfer-Encoding), you might want to set up the server to send it.

 

@BestHTTP

"It's usually when the server doesn't send a Content-Length header so the plugin can't know how much data it has to download."

So what does the Unity WWW class do then?

It would be great if BestHTTP had an option that replicated the Unity WWW class functionality, otherwise it feels like bug.

 

@puzzlekings

The HTTPRequest has an EnableSafeReadOnUnknownContentLength flag that you can set to false for a different read mechanism. The default one is a read bytes one by one, the other let's the underlying Socket implementation fill the provided buffer.
Unfortunately I see no other ways to read back the response for an unknown length of data and both mechanism will fail here and there. This is why I usually suggest to fix the problem on server side, as that's the best solution in this case.

 

hmmm - still don't know why the behaviour is different from the WWW class, as I would expect identical behaviour?

 

@puzzlekings

Until Unity isn't releases the sources, we will not find out. I guess different receive buffer size can play a role here too.
Also, even with Unity's implementation the behavior can be different on different platforms. My guess is that on standalone platforms they are using cURL, while on mobile they use the platform's own implementation.

 

@BestHTTP
Hello , I have one very strange issue.

"HeartbeatManager.Update" may not be running, If i refresh the current game page, unless the browser cache is cleared, will never execute OnHeartbeatUpdate，websocket is working..
"HeartbeatManager.LastUpdate " always output "01/01/0001 00:00:00"
"HeartbeatManager.Heartbeats" Count = 3.
WebGL Platform & All browser
BestHttp version : 1.10.3
i can send you a video..

 

@melefans

Is there a chance that you are using the Experimental runtime?

 

Sorry, I just saw your reply, I have modified my description of the issue..
If I refresh the browser, it will trigger this case。

 

@melefans

I would be happy if you can send any video and/or repro project!

 

Hello, I have already sent two emails to besthttp@gmail.com，one email is the video, the other one is the test project。
Yesterday I created an test project, unity editor and standalone platform can excute OnHeartbeatUpdate, but not excute in webgl, other platforms I have not tested..
Please check email as soon as possible

 

Hi,
The problem came back ;(
I tried following:
- restart Unity as you said - thousand times
- remove library folder
- re-import plugin
- install other version of Unity (current 2017.3.0 released on 19 dec 2017 and Patch version 2017.3.0p1 released on 22 dec 2017).

any ideas?

 

@w4der

Sorry, but i'm out of any idea.
Your best chance is to upload a repro project to Unity, so they can investigate it. It's still possible that something with the plugin itself, but at least they can let us know what's the problem, why it is failing.

 

Are there any plans to support http/2?

 

@gschemmel

I have plans for http/2, but it's a little low on my todo list currently.

 

Edit: Please ignore this. For Unity 5.4.5f1I had to use the Windows SDK Version 10.0.14393
Now the compile errors disappeared.

Hey, when I build for Windows 10 Universal Platform I get a bunch of compile errors with Unity 5.4.5f1 and BestHTTP version 1.10.2.
I have set Use Net Core for Compilation Overrides

Is there a specific Windows 10 SDK version I have to use or some special Visual Studio version?

Thank you in advance for your time

Hi!

I've got a problem with the OnInternalRequestUpgraded method after trying to create a web socket by upgrading an http request. The server accept the upgrade command and return a code 101, but the response won't cast in a WebSocketResponse and the code will handle this as an error. I can create a new WebSocketResponse from the HTTPResponse by using the constructor, but I have the feeling the cast should work. Any idea on what is going on?

Code (CSharp):

1. private void OnInternalRequestUpgraded(HTTPRequest req, HTTPResponse resp)
2.         {
3.             webSocket = resp as WebSocketResponse;
4.             if (webSocket == null)
5.             {
6.                 if (OnError != null)
7.                     OnError(this, req.Exception);
8.                 if (OnErrorDesc != null)
9.                 {
10.                     string reason = string.Empty;
11.                     if (req.Exception != null)
12.                         reason = req.Exception.Message + " " + req.Exception.StackTrace;
13.                     OnErrorDesc(this, reason);
14.                 }
15.                 return;
16.             }

 

@scauclair

I guess the url you want to connect starts with http:// or https://, in these cases the resp object isn't a WebSocketResponse and will fail. If you change it to ws:// or wss:// it shouldn't fail.

In the upcoming update this behavior will be improved and if you want i can send an updated package.

 

@BestHTTP

Urg, yup this is it. Thanks for the help!

Any Ideas what could be wrong with my code ?

It looks good to me, but it's enough to make a little mistake to fail the request.
Is it works in the editor? Or is it fails only under WebGL?

 

Hi it fails also in the editor not even tried in WebGL yet.

There's an example page where they have a sample input and signing output. You should try to sign the sample input with your functions to see whether you are receiving the very same output as they have on that page.

There's also an Examples of Signature Calculations Using C# (AWS Signature Version 4) secion where they even provide a downloadable zip file where there are complete classes for signing.

I would also try out the header based authorization too.

 

Hi, when I switching network from 3g to wifi (not disabling 3g, just turning on wifi) socket is closing. Is it possible to somehow prevent its closure?

Unfortunately, this is done by the underlying system, and the plugin has no control over it.

 

Hello, first of all thanks for your plugin. I could not get a SignalR connection to work on mobile, and your plugin made it easy and "just working".

However, I have been experiencing a problem. I had a working system to make HTTP requests using .NET 4.6 Experimental and WebRequests. Those requests used HTTPS, and went against an Amazon Beanstalk application running IIS with a self-signed certificate. After some fiddling with certificate validation, I made it work. The application also worked when queries from tools like Postman.

Recently, for various reasons, I decided to do a downgrade to .NET 3.5, in order to avoid issues with other areas of my game. And, given that i was already using BestHTTP, I switched the HTTP requests to the plugin. But, then, the requests against my self-signed server stopped working. They work at HTTPS in my local machine, they work against the server without HTTPS, and they work against test URLs like https://google.com, they just don't work against my custom server.

Getting technical, my code for performing a simple GET request is as follows:

Code (CSharp):

1.  
2.             // Create the request and set the headers.
3.             var request = new HTTPRequest(new Uri(uri + queryParams), HTTPMethods.Get);
4.             request.Callback = OnRequestFinished;
5.  
6.             // Configure the certificate validation.
7.             request.UseAlternateSSL = true;
8.             request.CustomCertificateVerifyer = new CustomVerifier();
9.  
10.             // Send the request.
11.             request.Send();

The custom verifier is taken straight from documentation, with a method that always returns true.

Code (CSharp):

1.     class CustomVerifier : ICertificateVerifyer
2.     {
3.         public bool IsValid(Uri serverUri, X509CertificateStructure[] certs)
4.         {
5.             UnityEngine.Debug.Log("IsValid called");
6.             return true;
7.         }
8.     }

When I perform a test request to, for example, https://google.es, the request works as intended. The debug line "IsValid called" shows up in the console.

But when I perform a request to my own server, everything goes awry. The callback method gets invoked with a null response object. The debug line in the IsValid method never shows (seems like the validation method is never called). And the request object passed to the callback contains the following error:

Code (CSharp):

1. "System.IO.IOException: Internal TLS error, this could be an attack
2. at Org.BouncyCastle.Crypto.Tls.TlsProtocol.FailWithError (Byte alertLevel, Byte alertDescription, System.String message, System.Exception cause) [0x00000] in <filename unknown>:0
3. at Org.BouncyCastle.Crypto.Tls.TlsProtocol.SafeReadRecord () [0x00000] in <filename unknown>:0
4. at Org.BouncyCastle.Crypto.Tls.TlsProtocol.BlockForHandshake () [0x00000] in <filename unknown>:0
5. at Org.BouncyCastle.Crypto.Tls.TlsClientProtocol.Connect (TlsClient tlsClient) [0x00000] in <filename unknown>:0
6. at BestHTTP.HTTPConnection.Connect () [0x00000] in <filename unknown>:0
7. at BestHTTP.HTTPConnection.ThreadFunc (System.Object param) [0x00000] in <filename unknown>:0 "

The fields UserAlternateSSL and CustomVerifier are correctly set, as is the URL. Any help would be appreciated. Thanks in advance.

Could you send me a non-working url to my email address (besthttp@gmail.com). It can be an error page, or something else, just to be able to reproduce this error.

 

I have the same issue but with SocketIO.
I am using Unity 2017.3 and the latest BestHTTP version.
When I stop the editor the code continues trying to reconnect.

Also If I stop my game while connected, the Unity editor crashes which is really frustrating.
(The only change we have is switching from standart socket client to BestHTTP so its not crashing from our code)]

Edit: The crashing happens if the callback attached to socket "error" event throws exception -> I guess it enters cycle. Anyway the first issue still exists

 

@exoter

Couldn't reproduce it yet. Can you confirm that you are using the v1.10.3 version of the plugin? You can find the version number in the \Assets\Best HTTP (Pro)\ReleaseNotes.txt.
