    - by Tony
    Hi We have two servers, both are containing a local application connecting to local web service, applications and services are identical on both servers. One of the servers work just fine, The other one is just dead, I have impression the the security configuration are different on those servers. What prevents an application X from connecting a web-service, given that another application y on the same server can connect to it. and X is a windows service. What I should check, what is chances? Thanks

  • query on custom field via webservice

    - by Roberto Parrotto
    I customized the content of Defect in my Rally workspace adding a new custom field. This custom field is of type string, its name is CustomTest and its display name is CustomAttribute. I added the value "test" on a defect, but I can't create a working query on that custom field (I'm developing in Java and using the ws api for rally). the query I tried are String query8 = "(CustomAttribute = \"test\")"; String query9 = "(CustomAttribute = \"test\")";

  • Authorization/Licensing of Webservice

    - by Burhan
    I have developed a web service which accepts the login credentials from the XML message passed to it. I have concerns over this method as the developer who consumes the service can easily share the login credentials and my service can be called from some other application that uses the same credentials. Is there any way that I can issue a 'license' to some specific applications? So that, even if credentials are shared among the consuming apps, only authorized ones can successfully consume the service. P.S: I thought about implementing IP restrictions but that doesn't serve the purpose as we may have different applications installed on a same server (we do have such a scenario implemented).

  • Creating WebService test harness

    - by user232337
    Hello, I am trying to create a test harness for our QA staff to test our internal web services. I would like to create a web app that will allow them to enter a uri then submit. The web app will then interrogate the uri to get the appropriate parameters expected and returns with a generated input form. I know, this would be similar to SOAPUI and others. However, I feel it would be earier for them to be able to just use a form with entry fields and click a button to invoke the service and get the results back for display in the web app. In addition, I could create some custom logic that allows them to generate specific behavior they need. Has anybody done anything like this? I have searched and have found similar functionality but nothing close enough to help me. If you need more details please let me know. Any help would be greatly appreciated. Thanks in advance! Ryan

  • securing a webservice for use from a custom iphone app only

    - by mme
    I want to create an iphone application which consists of two parts: The app itself and a server side component. On a users request, the app sends data to the server which is to be handled by human operators. To prevent abuse from an iphone app user, the id of the iphone is sent along with the request, and the operators can blacklist pranksters to deny their iphone access to the service. So far so good. Now the problem is: Someone could easily discover the address of the serverside component, and write a script to send bogus requests, using multiple IP addresses etc. So my question is: how can I defend myself against this? Captchas to protect against scripted attacks or requiring the user to register himself are not an option for this particular application. If I had control of the download, I would associate a unique ID with each downloaded app, but obviously this is not an option with the appstore. What would be your approach to make the server side part more secure?

  • WebService remote invoking fails.

    - by user569913
    I have a web service hosted on a web server, I invoke the web service using jquery ajax. The service returns results successfully when invoked locally from the server, but it fails when invoked from a remote client machine (not in the same domain). I see the request fail in the firebug returning error (401 UnAuthorized) and the response has the following error (Request format is unrecognized for URL unexpectedly ending in '/List').

  • Not getting an array as result (calling a webservice by AJAX-JSON)

    - by Pasargad
    I'm trying to get the result of my web service as an array and then loop over the result to fetch all of the data; what I have done so far: In my web service when I return the result I use return json_encode($newFiles); and the result is as following: "[{\"path\":\"c:\\\\my_images\\\\123.jpg\",\"ID\":\"123\",\"FName\":\"John\",\"LName\":\"Brown\",\"dept\":\"Hr\"}]" tehn in my Web application I'm calling the rest web service by the following code in the RestService class: public function getNewImages($time) { $url = $this->rest_url['MyService'] . "?action=getAllNewPhotos&accessKey=" . $this->rest_key['MyService'] . "&lastcheck=" . $time; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $data = curl_exec($ch); if ($data) { return json_decode($data); } else { return null; } } and then in my controller I have the following code: public function getNewImgs($time="2011-11-03 14:35:08") { $newImgs = $this->restservice->getNewImages($time); echo json_encode$newImgs; } and I'm calling this `enter code here`controller method by AJAX: $("#searchNewImgManually").click(function(e) { e.preventDefault(); $.ajax({ type: "POST", async: true, datatype: "json", url: "<?PHP echo base_url("myProjectController/getNewImgs"); ?>", success: function(imgsResults) { alert(imgsResults[0]); } }); }); but instead of giving me the first object it is just giving me quotation mark (the first charachter of the result) " Why is that? I'm passing in JSON format and in AJAX I mentioned datatype as "JSON" ! Please let me know if you need more clarification! Thanks :)

  • Ajax Autocomplete Extender

    - by Jason Ulloa
    El objetivo de este post es preparar un ejemplo sobre un tema que es planteado muy frecuentemente en los Foros de MSDN, como realizar un Autocomplete contra una base de datos. Qué requerimos? Antes de poder realizar un Autocomplete debemos tener en cuenta los elementos principales que requerimos para poder hacerlo funcionar, descritos de la siguiente manera: 1. Textbox: Nuestro grandioso amigo Textbox, que será donde el usuario ingresará los datos a buscar. 2. Un Webservice: que contendrá el método que se conectara a la base de datos y devolverá una lista con la información encontrada. 3. Ajax Autocomplete Extender: este es por decirlo así, el elemento más importante. Nos servirá como medio de enlace entre el webservice que expone el método y el textbox recuperando y mostrando los datos en forma de lista desplegable. La implementación Si bien parecierá complicado, crear un autocomplete extender es bastante sencillo. Empezaremos creando un nuevo sitio asp.net, en este sitio agregaremos un textbox y dos controles muy importantes de Ajax el ToolkitScriptManager para controlar el rende rizado de los script de ajax y el AutocompleteExtender que, como mencione anteriormente, será el medio de enlace. Antes de mostrar como quedará el código de lo anterior, explicaré algunas propiedades del AutocompleteExtender para que se entienda de mejor manera: 1. El ServicePath: contiene la ruta relativa al webservice que utilizaremos. 2. MinimumPrefixLength: se refiere al número de caracteres que deben ser digitados antes de iniciar la búsqueda. 3. ServiceMethod: el nombre del metodo de nuestro webservice que se encargará de devolver los datos. 4. EnableCaching: para mantener en cache los datos consultados, obteniendo mayor velocidad. 5. TargetControlID: una de las propiedades más importantes, acá se coloca el nombre del textbox al cual se unirá el Autocomplete 6. CompletionInterval: tiempo que debe transcurrir antes de iniciar con el trabajo de los datos. Una vez, explicadas las propiedades básicas, veamos como queda implementada la primer parte de nuestro autocomplete: <form id="form1" runat="server"> <div> <asp:ToolkitScriptManager ID="manager" runat="server" /> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" ServicePath="WebService.asmx" MinimumPrefixLength="1" ServiceMethod="PersonasInfo " EnableCaching="true" TargetControlID="TextBox1" UseContextKey="True" CompletionSetCount="10" CompletionInterval="0"> </asp:AutoCompleteExtender> </div> </form>   Ahora que nuestro código html está completo, es hora de trabajar directamente con nuestro webservice, este deberá contener un método que devuelva una lista o arreglo de datos, los cuales por supuesto, serán traídos desde la base de datos. Antes de implementar este método, debemos asegurarnos de que nuestra clase del webservice tiene habilitados los espacios para ser utilizada [System.Web.Script.Services.ScriptService()] [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class WebService : System.Web.Services.WebService {}   Ahora si, nuestro metodo principal [WebMethod()] [System.Web.Script.Services.ScriptMethod()] public string[] PersonasInfo(string prefixText, int count) { string connstring = ConfigurationManager.ConnectionStrings["LocalSqlServer"].ConnectionString;   using (SqlConnection conn = new SqlConnection(connstring)) { SqlCommand comando = new SqlCommand("select nombre from personas where nombre LIKE '%' + @param + '%' ", conn); comando.Parameters.AddWithValue("@param", prefixText); SqlDataReader dr = default(SqlDataReader); comando.Connection.Open(); dr = comando.ExecuteReader(); List<string> items = new List<string>();   while (dr.Read()) { items.Add(dr["nombre"].ToString()); } comando.Connection.Close(); return items.ToArray(); } }   Del método anterior no explicaré en profundidad, pues es bastante sencillo. Una consulta a la base de datos utilizando un datareader y devolviendo los datos en una lista como arreglo. Lo más importante serían las 2 primeras líneas [WebMethod()] y el [ScriptMethod()] las cuales habilitan nuestro método para poder ser accedido y utilizado. Por último, el código de ejemplo en C# (VB Autcomplete):

  • How can I call VC# webservice methods without ArgumentException?

    - by Zarius
    Currently, I'm trying to write a small tray application that will show the status and provide control of a server-side application exposed over webservice. The webservice only has 3 operations: start, stop and status. When I call any of these operations in code, they throw an ArgumentException citing "An item with the same key has already been added". I am compiling the webservice on Visual C# Express 2008, and .NET 3.5. The Code: private TelnetConnClient Conn { get { return new TelnetConnClient(); } } private bool Connected //call webservice operations { get { return Conn.Status(); } set { if(value) Conn.Start(); else Conn.Stop(); } } The Stacktrace: A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) at System.ServiceModel.TransactionFlowAttribute.ApplyBehavior(OperationDescription description, BindingParameterCollection parameters) at System.ServiceModel.TransactionFlowAttribute.System.ServiceModel.Description.IOperationBehavior.AddBindingParameters(OperationDescription description, BindingParameterCollection parameters) at System.ServiceModel.Description.DispatcherBuilder.AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection parameters) at System.ServiceModel.Description.DispatcherBuilder.BuildProxyBehavior(ServiceEndpoint serviceEndpoint, BindingParameterCollection& parameters) at System.ServiceModel.Channels.ServiceChannelFactory.BuildChannelFactory(ServiceEndpoint serviceEndpoint) at System.ServiceModel.ChannelFactory.CreateFactory() at System.ServiceModel.ChannelFactory.OnOpening() at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.ChannelFactory.EnsureOpened() at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address, Uri via) at System.ServiceModel.ChannelFactory`1.CreateChannel() at System.ServiceModel.ClientBase`1.CreateChannel() at System.ServiceModel.ClientBase`1.CreateChannelInternal() at System.ServiceModel.ClientBase`1.get_Channel() at KordiaConnect.ferries.TelnetConnClient.Start() in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Service References\ferries\Reference.cs:line 86 at coldshark.ferries.Main.set_Connected(Boolean value) in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 22 at coldshark.ferries.Main.<.ctor>b__0(Object sender, EventArgs e) in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 43 at System.Windows.Forms.NotifyIcon.OnClick(EventArgs e) at System.Windows.Forms.NotifyIcon.WmMouseUp(Message& m, MouseButtons button) at System.Windows.Forms.NotifyIcon.WndProc(Message& msg) at System.Windows.Forms.NotifyIcon.NotifyIconNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.PeekMessage(MSG& msg, HandleRef hwnd, Int32 msgMin, Int32 msgMax, Int32 remove) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run() at coldshark.ferries.Main..ctor() in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 55 I can just call the webservice from the web interface, but this application will give me a handy status notification icon, and I'd really love to know why the out-of-the-box auto-generated code fails for no particular reason.

  • What's the simplest way to provide a portable, locally running webservice server application?

    - by derFunk
    We have a bigger website running that offers a JsonRpc web service. For offline demonstration purposes I want to realize a portable, locally running webserver with a minimalistic feature replication of the live webservice, and bundle this together with Html files which do Ajax requests to it. This local server executable should have as little dependencies as possible. It's gonna be run and presented by non-devs on non-dev Windows machines, so I would prefer having a simple executable plus the service code - whereas language doesn't matter as long as it is .NET, PHP or Java. I'll need a small database behind which probably will be Sqlite. It's important to say that for some reasons we cannot use the original web service code, but we have to rewrite it new for the local demo server, this is why I want to put minimal effort in the local server tech. An installer for distribution is not mandatory, it's okay to have a zip file with an executable in it which starts up the local webserver. What would you recommend realizing these requirements? I've done some research already, but would love to here your opinions and get some pointers!

  • Can I use the AJAX Autocomplete extender *without* a webservice?

    - by David
    Using ASP.NET 3.5 with VB codebehind. I don't want to use a webservice to populate an autocomplete extender on a textbox. In this case, it's where the user is entering email addresses and I don't want to make a trip to the database every single time. I'd much rather keep a collection in session state and 'bind' the autocomplete to that. Is it possible to set ServicePath and/or ServiceMethod to something in the codebehind as opposed to a webservice?

  • Web Service returning object with null fields

    - by Xaiter
    Never seen this one before. WebService.Implementation imp = new WebService.Implementation(); WebService.ImplementationRequest req = new WebService.ImplementationRequest(); return imp.GetValue(req); The object that imp returns is not null. It's returning an ImplementationResponse, as expected. But all of the fields in that object are null. Which is not expected. The WebService, currently, just returns some constant dummy data. We've tested this on another developer's machine, works just fine. I suppose I should also note that the WebService should throw an exception if I pass null into the GetValue method. It doesn't. Not for me. Any idea what could be wrong with my environment that could make a WebService return an object, but make every value in that object null? And somehow 'magically' return this mystery object when it should be throwing an exception?
