Best HTTP Released

@just_a_joke can you see something suspicious in the logs?
Also, the default Json encoder may not able to convert to Json string a complex object like this. You can try out the more advanced LitJson encoder:

Code (CSharp):

1. signalRConnection.JsonEncoder = new BestHTTP.SignalR.JsonEncoders.LitJsonEncoder();

A possible workaround can be to pass the object's fields as params, but for this you have to modify your function on server side too.

 

@BestHTTP We unable to find the class "LitJsonEncoder" in the downloaded package. Inside the "JsonEncoders" folder, there are only "DefaultJsonEncoder" and "IJsonEncoder".

Besides that, is the signalR Call function only accept string as the argument or I could pass in the object class.

The following is the server-side function structure :-

Code (CSharp):

1. private void result (resultItem item)
2. {
3.       //some process
4. }

Thanks

 

@just_a_joke The LitJsonEncoder must be in the \Assets\Best HTTP (Pro)\Examples\SignalR\Json Encoders\ folder.

The Call function accepts objects too, it it has to convert them to json for the SignalR protocol. The default json encoder can deal with simple types(int, floats, etc.) and with little more complex ones (like arrays, Lists, Dictionarys where the generic types are simple too). But for custom classes a more advanced json encoder adapter must be set, or you have to do workarounds:
-send fields as distinct params
-add the fields to a Dictionary<string, object> and pass this dictionary to the function.

 

@BestHTTP I tried to parse the class object into json string using the LitJsonEncoder as following :-

Code (CSharp):

1. string content = signalRConnection.JsonEncoder.Encode(resultItem);

But there is an error on the encode which the output for "content" is Max allowed object depth reached while trying to export from type System.Guid. Which one of the object type in the resultItem is Guid

I tried pass in the object as argument for the Call method which the object class type is exactly the same as the expected class type on the server-side. But the server-side function still not fire.

Thanks

 

@just_a_joke You can place this code somewhere in your startup code:

Code (CSharp):

1.         LitJson.JsonMapper.RegisterExporter<Guid>((guid, writer) => writer.Write(guid.ToString()) );
2.         LitJson.JsonMapper.RegisterImporter<string, Guid>((input) => new Guid(input) );

These are custom GUID => Json and Json => GUID mappers that the LitJson encoder will use.

 

I am having trouble with HTTPRequest: the requested is getting queued endlessly even after I stop the app. any suggestions?

 

@hugewindow Can you share more detail? You can turn on more logging for the plugin this way:

Code (CSharp):

1. BestHTTP.HTTPManager.Logger.Level = BestHTTP.Logger.Loglevels.All;

Also, any chances that redirection occurs in one of the requests? A new version already uploaded to the Asset Store that fixes an issue like this.

 

Hello, I just bought this plugin and I am enjoying it very much! I have a question about server callable methods for SignalR though: what is the best way to deserialize a MethodCallMessage Argument into a typed object? Right now I see it is a Dictionary<string, object>. Do I need to manually map it from the dictionary?

Thanks!

 

Hello,
I have BestHttp Pro.
All work fine in android and ios but in WebGl plateform (with editor running) I have the following error:

6.             request.Send();

In the url string i have "http://PhoenixPokerWebApi.phoenixgames.fr/api/values/MasterServerAddress"

Best

 

@agriffin You see it well. Right now this your only option. Already thinking about adding support for generic callbacks with strongly typed arguments, but the first problem is the SignalR message format, the second one is the AOT compiler for iOS.

 

@V Marquis Tried you code with the link you provided, but the request runs fine and I received a valid answer.
However if you pass the address that you receive back from your server to the Uri's constructor, you will receive this error.

As you can see, the exception is thrown in Photon's code(PhotonPeer.Connect) you called from the callback function(BasePartyManager.OnRequestFinished).

 

It would be awesome if you can figure out a way to implement it but for now I am happy! Thanks for this awesome plugin!

Getting the above in the 5.1.3f1 editor periodically after it rebuilds unrelated code. Anyone else seeing that?

 

@slumtrimpet
I receive them too(or, at least reproduce these kind of messages), but they are because Unity doesn't shut down threads when you stop the editor. All requests are keep running. These will stop when 1.) they are finished or 2.) Unity recompiles.

 

Ah, ok. Thanks for the quick reply. I'll not worry about this one then.

 

Hi,

I get an error on Unity 5.0.1p3 (and also on the newest 5.1.3 build) when including the besthttp dll (basic) in the project. Platform iOS (others work fine), architecture universal, il2cpp, .net full.

What could be wrong here? Would it be a better fit if i would go with the pro version with code only and no dlls or wouldn't that matter?


Thanks

 

@illuminat Thanks for the detailed report. This error is already fixed in v1.9.1 and uploaded to the Unity Asset Store, but it isn't released yet by Unity. I will send you a private message with a download link for this updated package.

 

Perfect, it works. Thank you for the fast answer!

 

Hey BestHTTP,

I am getting the following error:

Request Finished with Error! Array index is out of range.
at BestHTTP.HTTPResponse.Receive (Int32 forceReadRawContentLength, Boolean readPayloadData) [0x00000] in <filename unknown>:0
at BestHTTP.HTTPConnection.Receive () [0x00000] in <filename unknown>:0
at BestHTTP.HTTPConnection.ThreadFunc (System.Object param) [0x00000] in <filename unknown>:0

any ideas why this could be happening?

=======

Just found the answer for this, already in this forum.. sorry for my impacience..

int retryCount = req.Tag == null ? 0 : (int)req.Tag;
if (retryCount++ <= /*maxRetry:*/ 3)
{
req.Tag = retryCount;

// send the request again.
req.Send();
}

 

@ayalasan This error usually occurs when
1.) The server closed the tcp channel but the plugin tried to receive a response on it. Without going into detail, you can try to lower the MaxConnectionIdleTime (the default is 30 sec, you can try different values):

Code (CSharp):

1.  
2. BestHTTP.HTTPManager.MaxConnectionIdleTime = TimeSpan.FromSeconds(15);

2.) Sometimes, when the default SSL handler can't decode the secure stream it will result in an error like this. In this case you can use the alternate SSL handler:

Code (CSharp):

1. BestHTTP.HTTPManager.UseAlternateSSLDefaultValue = true;

 

Hi BestHTTP,
I just sent you an email about this but this thread is probably a better place for this question:

Has there been any thought towards supporting PAC files for use with proxy servers? I'm in a situation where this is needed, so I'm wondering if this is something that is on the roadmap or whether we would have to add support for this ourselves, or whether it's even possible in the first place.

Thanks

 

@eventropy Replied in mail.

 

I'm stumped. I assume this is something silly, but still stumped.
Trying to send binary data to socket.io.
Client =
byte[] data = new byte[10];
manager.Socket.Emit("DataUpdate", data);
(I tried sending encoded strings, and filling out the array too)

Server (Node)
socket.on('DataUpdate', function (BufferData)
{
console.log("Buffer data is "+BufferData);
}

Console output - Buffer data is {"_placeholder":true,"num":0}

If I send a string it works fine.

How do I send binary data from Unity to the node instance correctly? Is it already passed in in the event and I'm just using it incorrectly?

 

@Lord_Pall This issue has been fixed in v1.9.1, but I still waiting for its release from the Unity guys. Let me know what version of the plugin you have (Basic/Pro), and i will send you a download link.

 

PMed. Thanks for the quick response.

 

Hi

I'm developing an image application that loads images from net, what i want to have is 1 instance of BestHTTP Pro that can be used to send multiple requests, and BestHTTP loads them one by one. I have also the possibility of canceling the request so lets say i made 10 reqeusts and 5 images got loaded and 5 are pending. if i call cancel method then besthttp only cancels those pending requests.

 

@aammfee
You can send out multiple requests, but how many will be processed in parallel depends on the value of the HTTPManager.MaxConnectionPerServer property. The default value is 4, but you can change it to 1. This way requests will be processed one by one.
You can check out my online demo, the "Texture download" sample demonstrates how you can do it: http://bit.ly/1AkM6gi

To cancel a request you can call the Abort() function on the HTTPRequest objects. It will do what you expect, you can cancel the remaining 5 requests.

 

Hi,
I'm using BestHTTP 1.9.0 and I just tried to build an iOS version on my project with the new Unity 5.2, but I can't manage to generate XCode project

Here is what I get :

I tried to add the System.Security.Principal.GenericIdentity class into a link.xml file, switched to .Net 2.0 level, uncheck "Strip Engine Code", all of this at the same time, still the same error.

Any idea ?

 

@Ly
I'm currently trying to investigate it. Neither of these two classes are used by the plugin directly, and i don't know yet what depends on these. As I see, your only option is to downgrade to Unity 5.1.

 

Ok, thanks for your quick answer. Btw i'm using Pro version of Unity & BestHTTP. Can you reproduce this error ?

 

@Ly Yes, I can. But it looks v1.9.2 is working somehow. This version is still in pending status in the Asset Store, so I will send a download link to you in private.

 

For me, v1.9.2 compiled with the following settings:
-IL2CPP + Engine Stipping + .NET 2.0 API compatibility
-IL2CPP + Engine Stipping + .NET 2.0 Subset API compatibility
-IL2CPP + .NET 2.0 API compatibility
-IL2CPP + .NET 2.0 Subset API compatibility

 

Thank you for your link. Sadly, I still can't build my project, I get the exact same error :/

I removed completely the BestHTTP plugin and re-added with 1.9.2 version, and tried all configurations above.

Maybe I'm missing something ?

 

@Ly Well, my test project contains only the plugin, maybe is it possible that an other plugin that you use has this issue too?

 

@Ly And of course I can't say for sure yet that 1.9.2 can't trigger this build problem.

My last working setup:

 

Thank you for your time, I just managed to isolate and find the issue by comparing my project with a new empty one...

To fix this, you have to lower the stripping level. Yes, the Mono stripping level. In my project it was 'use micro mscorlib', so I switched to Mono, changed to 'strip byte code', and re-switched to IL2CPP. And voila. Please don't ask me why.

So it was absolutely not because of your great plugin. Now it works, even with 1.9.0. Sorry for your time loss. And not thank you Unity. Grmbl.

 

@BestHTTP, which values for MaxConnectionIdleTime would you recommend using?

For instance I tried with MaxConnectionIdleTime = 15 but the error is still happening.
I tried MaxConnectionIdleTime = 3 and now the error seems to be gone.

I am wondering, how little can this value be so that a solid connection is handled between the client and the server?

 

@Ly Hahh, and it works....!

 

@ayalasan It depends. If you are sending out requests rapidly, 3 secs can be a lot of time. If you are sending requests here and there, it might be better to disable it completely to free up server resources as soon as possible.

Also, keep-alive values can be changed on the server too, so you can experiment with different values on the server too. But usually it's easier to change values on the client as server setups may be unavailable for you.

 

Hey @BestHTTP,
your feature list only says Latest SignalR version supported. But before i buy your product I have to know if SignalR 2 is supported.

arodes

 

@arodes I test the plugin against the latest GitHub version.

 

Thanks for your help.

 

@BestHTTP alrighty then

Just to round up things a bit more, we are indeed throttling the server(s) quite a bit, we target 2 endpoints every 3 secs or so. Would you say having a MaxConnectionIdleTime = 1 is plausible without affecting or producing any timeouts? I will start fuzzing with client side connections only, since we don't have direct control over the servers.

Thanks again!

 

@ayalasan If you are sending out requests less frequently than the MaxConnectionIdleTime (you are sending out requests every 3 secs, but the plugin will close the connection after 1 sec idling), then you should disable it completely:

Code (CSharp):

1. BestHTTP.HTTPManager.KeepAliveDefaultValue = false;

 

Hi,

I'm facing an issue on Unity 5.2 on Windows Store Universal 10 platform.
I've created a project containing only BestHttp 1.9.0.
I'm getting this error when I build the solution in Visual Studio.

Hello there! @BestHTTP I was wondering if you could shed some light on an error I am getting that prevents networking from working. Only some computers give this error, so I am having a hard time figuring out why it is trying to reference a local file:

It has come up on 2 computers when 6 others work, Mac and Windows. This error will occur in builds as well as in the Unity editor, and currently one teammate cannot get rid of it even when I try deleting my libraries and rebuilding.

 

@Dynamoid Megan The exception occurred in the callback function of a http request. Can you share what's around line 105 in the Assets/Scripts/Networking/NetworkingController.cs?
One possible reason can be if the request fails, and the response object is null.
