    AFAIK Unity Free does not support sockets on these problems, and therefore UniWeb will not work.

    I need more information to help you. Did you change the REST api key to suit your own application?

    Yes absolutely, all I did was fill in my Parse keys which I am very familiar with Parse so i am sure I have the right ones.

    I just filled in where you had strings asking for them, Parse.cs I think it is?

    This is a 401 status code, which means Parse.com is telling you that you submitted an invalid password. The helpful message is output by UniParse to tell you this. Have you created the user you are trying to authenticate?

    Okay, here is one of the classes:

    Code (csharp):
    1.  
    2. using UnityEngine;
    3. using System.Collections;
    4. using System.Net;

    90.             return true;
    91.     }
    92.  
    93. }
    I ported the java example code from vuforia to C#. Infos could be found here: https://developer.vuforia.com/resou...ng-targets-cloud-database-using-developer-api

    This class is used by the main class "VWS_API" and looks like this:

    Code (csharp):
    1. public class VWS_API : MonoBehaviour {
    2.    
    3.     public static string accessKey  = [access_key of server account];
    4.     public static string secretKey      = [secret_key of server account];
    5.     public static string url                = "https://vws.vuforia.com";
    6.    
    7.  
    8.     // Use this for initialization
    9.     void Start () {
    10.        
    11.         Debug.Log("Initialize VWS API");
    12.        
    13.         PostNewTarget.postNewTarget("stones","stones");
    14.        
    15.     }
    16.  
    17.     //set authorisation header to request
    18.     public static System.Collections.Hashtable setHeaders(Byte[] data,String requestPath,String method) {
    19.  
    20.                          //...
    21.  
    22.         }
    23.    
    24.  
    25. }
    26.  
    If you need more specific informations, tell me!

    Thanks for your help! :)

    P.S.: Changing the line "yield return null" to any other yield-commands dont solve the problem. tried break, WaitForFrame() ant WaitSeconds() .

    Your PostNewTarget class does not inherit from MonoBehaviour, therefore it will not be able to directly use coroutines.

    No, allready checked that. It have nothing to to with the fact, that the class dont inherit from MonoBehaivour. If i change the class to MonoBehaviour, unfourtunatlly i have the same problem :(

    I assume you're calling the routine with something like StartCoroutine(PostNewTarget.postNewTarget(...))? It might be worth your time reading up on how coroutines work and their relationship to monobehaviour classes etc.

    No i dont use StartCoroutine.

    But you are right, I definitly have to take the time, to work trough the coroutine-thing, but i dont understand, why it dont work, even if i make the whole class to a MonoBehaviour class and use it like any other Mono-Scripts?

    I added " : MonoBehaviour" to the class head, added a Start()-Function to the class and call the PostNewTarget-Method from the Start-Function. Then I added the Script to an GameObject, and started the application in the unity editor.

    Even if i messed up with my non-mono class, it has to work, if i use the "regular" way, or do i miss something? :?

    Hello,

    I am just getting started with UniWeb and am trying to figure out how the caching works. I can't see from the code how it is implemented.

    Please advise.

    Thank you

    In your Start method, you will need to use the StartCoroutine method to actually start the postNewTarget coroutine. I'm also not sure that you can have a static MonoBehaviour.

    Simon,

    I downloaded UniWeb (which I only paid for because of UniParse)

    I added my keys in the UniParse.cs script EXACTLY as they appear in Parse:

    string RESTAPIKey = "";
    string applicationId = "";

    I got your message about an invalid user which I think is hilarious because this is your code CREATING a user then LOGGING that user in so one would think if that is how you designed your demo it would just work?

    Code (csharp):
    1.  
    2.     //Register a new user
    3.         var user = ParseClass.users.New();
    4.         user.Set("username", "itjunkii");
    5.         user.Set("password", "123");
    6.         user.Create();
    7.         while(!user.isDone) yield return null;
    8.         //check for error
    9.         if(user.error != null) {
    10.             //A message is printed automatically. We can diagnose the issue by examing the HTTP code.
    11.             Debug.Log(user.code);
    12.         }
    13.        
    14.         //Authenticate an existing user
    15.         var auth_user = ParseClass.Authenticate("itjunkii","123");
    16.         while(!auth_user.isDone) yield return null;
    17.         //check for error
    18.         if(auth_user.error != null) {
    19.             Debug.Log("An error occured, likely a bad password!");
    20.         }
    21.  
    Have you ran your demo project straight from the store lately? Are you capable of solving this problem? If not please do let me know so I can move on with my life.

    Remember UniParse is free, so there has not been a large amount of time into making it super easy to use.

    However, I've been using UniParse V2 for some time now, but am running into trouble getting it onto the Asset Store. If you would like to see this version drop me a private email and I'll send you the package. It's much better than the version currently on the asset store.

    Hi,

    I'd like to know if the https call ACTUALLY validates the certificate or skip it making the library vulnerable to Man-in-the-middle attacks

    To be honest, I don't know. I use the .NET SSL classes, and I'm not sure if they do any validation automatically, or whether this needs to be coded in manually.

    Yes, that does the trick, thanks! And it works with a non-mono static class ;) Dont have to use MonoBehaviour!

    But now i have an other problem: How to set the Content-Type header correctly? If i use request.headers.Add("Content-Type","application/json"); i got a 500 result code from the server.

    For requests without a request body(like a get request) everything works fine now, but if i need the Content-Type to set to "application/json" my request dont work anymore.

    Any ideas?

    Thank you again for your help!

    I have been working with UniWeb/UniParse for some time now in an app we have live in the store. It seems 1 out of ever 4-5 times I run the app, I get an exception regarding cookies from Parse.com. Once this happens, it seems any other calls to UniWeb fails with something similar until the app is restarted. Is there perhaps a way to just disable cookie handling or something, since I know this is not needed for Parse. Thanks!

    You can modify the code yourself to remove any cookie related features, however I will add this as a feature for the next version so you can easily switch off cookies.

    UniWeb 1.9.22 is about to hit the asset store. Contains some important bug fixes, including the unterminated stream exception!

    Hi,

    To support strip on iOS, you can also add a link.xml file at the root of the project :

    Code (csharp):
    1.  
    2. <linker>
    3.     <assembly fullname="mscorlib">
    4.         <namespace fullname="System.Security.Cryptography" preserve="all" />
    5.     </assembly>
    6. </linker>
    7.

    I seem to be getting a crash on occasion with this error:

    HTTP.HTTPException: Unterminated Stream
    at HTTP.Response.ReadLine (System.IO.Stream stream) [0x00000] in <filename unknown>:0
    at HTTP.Response.ReadFromStream (System.IO.Stream inputStream) [0x00000] in <filename unknown>:0
    at HTTP.Request.<Send>m__18 (System.Object t) [0x00000] in <filename unknown>:0

    Also I would love to see stripping supported.

    Disabling completely the stripping for System.Security.Cryptography using link.xml increases the build size of 305kb. I would not recommend this solution.

    Hi!, there would be any new examples?

    Some of us here would like to check something like client-server small example, perhaps something like a game control from another exe, or perhaps from a html website.

    Is this possible?

    Hi all

    I am currently developing with the webplayer and want to use UniWeb with parse.com but it seems they have no socket policy server :( , Does anyone know if there is any Baas service that supports a socket policy server?

    Thanks

    Yes but what do you propose if we need the System.Security.Cryptography ?
    For example, in Request.cs there is the method :
    Code (csharp):
    1. public static bool ValidateServerCertificate (object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
    that uses X509Certificate and X509Chain that are in this package :/

    Unity relies on static code analysis in order to detect what is needed and what is not, however it seems to fails for some things (Like the .Create() methods of the providers or with reflection in general)*.

    Most of the time it works well so what we do is avoid the use of "link.xml" since we want to be under 50mb and that 300k is not negligible.

    I recommend to test thoroughly all the features without using link.xml and fix what can be fixed (Ex: changing a .Create() for a "new" in this very specific case). Also, it appears we can be more specific in link.xml at using "type" instead of namespace in order to specify specific classes that fails.

    *: "Stripping depends highly on static code analysis and sometimes this can't be done effectively, especially when dynamic features like reflection are used. In such cases, it is necessary to give some hints as to which classes shouldn't be touched." http://docs.unity3d.com/Documentation/Manual/iphone-playerSizeOptimization.html

    Thanks for the answer,

    Yes, but ! in this particular case, we must implement the ValidateServerCertificate method and thus use X509Certificate :/

    But as you said, I'll try to add just the 2 classes and not the whole package System.Security.Cryptography, but I fear this won't work because of dependencies...

    EDIT : Yup... does not work :)

    The best would be to checkout the source code of mono that was used in your version of Unity and look for Reflection in the code that is called before it crashes.

    The problem could be in SslStream in example.

    Have you tried only with the namespace System.Security.Cryptography.X509Certificates in link.xml?
    Code (csharp):
    1. <linker>
    2.     <assembly fullname="mscorlib">
    3.         <namespace fullname="System.Security.Cryptography.X509Certificates" preserve="all" />
    4.     </assembly>
    5. </linker>

    I guess is not a policy server, since it doesn't respond to <policy-file-request/>. Also, today I ran the same test and I couldn't even connect to that port (connection refused). I give up on trying to use uniweb for my facebook client, still using it to connect to the game API which runs in my own servers.

    Hi there,

    I have one question. Does your GoogleMaps plugin in combination with UniWeb work when I build to Unity or Flash Webplayer?
    When researching and testing I find that the sandbox security normally poses a problem - basically one needs to put a crossdomain.xml on the google server to prevent this.
    Do your plugins circumvent this issue?

    My game is multiplatform (web, ios, android), and the problem only occurs in the web version. As I understand it,due to the security sandbox implemented by the webplayer, the server to which you want to connect has to be running a policy server if you are connecting using sockets, which is the case with UniWeb. Facebook doesn't run such policy server, so I guess you can't connect to it using UniWeb if your game has a web version.

    No, the plugins do not work as google would need to provided a crossdomain.xml policy server, as you suggested.

    Hi there. I'm using UniWeb because I'm using ElasticSearch as my remote data store. The reason for this is that I'm trying to send a lot of data back (performance metrics per-frame and replay data) and a standard PHP/MySQL service is too slow. I can't use the WWW class because ES uses a very strict REST API and it is important that you be able to specify the request method (GET, POST, etc.).

    Just using HTTPRequest and HTTPResponse from .NET is working, but there's a pretty major blocking period (~250ms or longer) when the request is sent. It looks like you can make these calls asynchronous, but I figured I could save myself some time by trying UniWeb.

    Unfortunately, UniWeb isn't working at all. I enter the same URL (with port) and data as was working with HTTPRequest, but with UniWeb I get an error:

    System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it.

    Any ideas?

    Hmmm from here it would seem that perhaps the URL is not specifying the correct port? Are you able to show the URL you are using?

    Sorry can't help you here :/
    We'll be working on a Facebook WebPlayer port soon, but nothing for the moment. If you find a way, please share it :)

    Actually, it looks like the server was down! HA! I can't check right now but I'll let you know if it's any other issue :)

    Out of curiosity, will the Request class solve my blocking problem?

    Hi,

    i'm currently considering buying your extension but would like to know how far your socket.io integration is.
    According to your description you support it. Does that mean you've implemented the entire socket.io protocol?

    Do you have a trial version for Uniweb?

    Thanks in advance for your answer

    - Node.js + Socket.IO + Websocket protocol. : stable.
    - SuperWebsocket 0.8 + private socket policy server : stable
    - Alchemy Websocket + private socket policy server : unstable.

    Hi again,

    So after recognizing my face-palm-server-fail, I'm able to successfully read/write to the server over HTTP. However, I've started getting some mysterious Unity Editor crashes since adding the calls to UniWeb. Then again, I'm on a different machine than I normally am right now, so it could be something unrelated. I'll let you know if I get more details on the nature of the crash.

    Hi.

    Assets/UniWeb/Plugins/Utility.cs(6,14): error CS0234: The type or namespace name `Web' does not exist in the namespace `System'. Are you missing an assembly reference?
