C# - Implement Restful Url In .net Where Service Is Implemented Using IHTTPHandler?
Jan 18, 2011
I want to implement a restful service in ASP.NET. I want it to be compatible with .Net 2.0 and IIS 5+. I am constrained to not use ASP.NET MVC or REST starter kit. By reading on internet I have learned that it can be implemented using HTTPHandlers. The problem is, the request will come in as a POST request. And I want to URL to be like:
http://abc.com/MyService/MyMethod1/
and
http://abc.com/MyService/MyMethod2/
First, I'm looking for a a small example of how to handle a series of RESTful URLs, such as /Account/{userName} and /Account/{userName}/Profile with a single HttpHandler. At this time, I'm not interested in embracing MVC or using the REST Starter Kit. Should I place the HttpHandler class in a Class Library? Should I publish to the root of the RESTful URL?
My second issue stems from the fact that my ASP.NET hosting is done through a web-hosting company. Will I need to ask their tech team to configure IIS for me? Is that normal practice?
<Application architecture>I'm developing ASP.NET Web Application by Visual Studio 2008.(.Net Framework Version = 2.0)I put followin two projetcs in the solution.a. Class library which implements all the buisiness logic for application. (I'll call it "ClassLib" in the followin sentence)b. ASP.NET Web applicatoin which presents UI.(I'll call it "WebApp")ClassLib uses Web Service which located on other server. So, I set web reference in it. Method for url settings for this web reference is "Dynamic".
I simply want to create a fairly basic REST service, so that I can expose some of the data in my asp.net/SQL server application to the outside works, like this.....
http://domain.com/api/offices - would return an xml set of office locations. http://domain.com/api/offices/15 - would return all the details of office 15.
It's all fairly standard stuff (including basic authentication) but there seem to be several ways to achieve this using Microsoft technologies and I don't really know where to start. These seem to be the options...
1) WCF
2) ASP.NET MVC
3) ADO.NET Data Services
4) Rest Starter Kit project templates?
Which of these is the easiest and most "up-to-date" solution to creating a web service?
I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)Code is as follows.
I am using VS2008 pro to develop my web application. my project target framework is 3.5. I can add web service (.asmx) to it. But there is no .svc for me to add, do I need to install WCF REST Starter Kit? (but it is only in Preview 2)Or should I add an WCF service project to my solution?
i am in the process of creating a restful service with WCF, the service is likely to be consumed by at least 500 people at any given time. What settings would i need to set in order to deal with this.
I have xml document and wanting to pass it through wcf restfull service, i am able to do that by using string format i mean i can pass the xml as string param in the restful service and it worked but now my xml document becomes huge so if i pass it as string then it gives URI long error. any way i can pass the huge xml document through the WCF RESTFul service.
What is the best way to implement a open/cross platform web service API to an existing .NET App? Not being a strictly .NET friendly API. It already has ASP.NET exposed web services, but need to be built into an generic API allowing inserts, updates and deletes and returning results based on user criteria in standard SOAP, JSON or other common formats, similar to Google's Data API's. Are there any frameworks designed for this or is it a build it from scratch project implementing each format/protocol manually?
I am new to the wcf services and soap. Kindly give me an example or demo how to generate a soap request and response using wcf services. I need to use VB.net for this.
We have a common WCF service Which takes stored procedure name and value as parameters from .ASPx page and execute in Database. In some cases, We need to execute 3-4 stored procedure in Sequence. Here, If any stored procedure fails then we need to rollback. How can we implement Transaction with WCF service.
Using autocomplete with <ajaxToolkit:AutoCompleteExtender but nothing happens. The textbox has autopostback=falseon debugging autocomplete.vb page nothing happens
WebService
Public Class AutoComplete Inherits System.Web.Services.WebService <System.Web.Script.Services.ScriptMethod(), _ System.Web.Services.WebMethod()> _ Public Shared Function GetCustomers(ByVal prefix As String, ByVal count As Integer) As List(Of String)
I am trying to implement a service to download a image file. The code does nothing but upload a file to the response with each client request.
There are no SOAP messages involved but I am planning to implement it as ASP.NET web service. It can also be implement as ASP.NET website but since it has no view (forms, html etc) I planned to implement a web-service.
I'm working on an ASP.NET MVC web application that will be deployed across multiple load-balanced servers. With this setup, a user might have one request served by server A and the next request will be served by ServerB or ServerC. We don't want to store Session Data in the database, as we're trying to minimise database hits where ever possible. As such, we need to have the HttpSession managed and stored on another server. My understanding is that this is possible by using a Windows Service that will manage this for me, but I'm unfamiliar with how to implement this. Can somebody point me at some good documentation on how to do this? Or any pitfalls or other points to take into consideration?
I am currently working on a project that is very new to me, and I feel a bit over my head as far as knowledge base is concerned. My request is for references and information to help me expand my knowledge base, as well as recommendations for technologies and methods.I have experience primarily with Java, so all this Windows service stuff is new to me. I am not really asking for a how-to
The project is as follows: I am to develop an application in ASP.NET that runs as a process from start-up to shutdown. It will be checking some things in a folder, encrypting some files from that folder, and then check if internet connectivity is available. If it is available, it will be sending those files to a server (via a web service on that server, I believe). If it is not available, it will check every 'insert time interval here' to see if connectivity has become available, at which time it will send the files. Once the files are received by the service, the application will need to recieve some kind of confirmation from the server that the file associated with 'xxxxxxxxxxxxx' uniqueidentifier has been received.
Any explanation of the way that web services work or how to implement file encryption in a desktop app (resource load optimization is a very substantial requirement of this app).
i am working in asp.net mvc & want to create a restful web service. how can i create a restful web service in MVC & how can i use it ? My requirement is : i have an application server which send some parameters to web service & the web service should connect to remote server & return image on path (whose path will be generated by the parameters from application server).
Actually the handler never gets called. I already searched the forums and tried some tips and hints. But nothing of that worked. Try to call the url via[URL]
I have a restful controller that has your standard REST HTTP Verbs: Get,Post, Put, Delete. The problem I am having is that although my controllers are decorated to accept these verbs, when I execute my REST action, it can only hit my Get and Post methods. I have the attributes on top of the controller actions: HttPut, HttpDelete, HttpPost, and HttpGet. I also have the the override method in my forms: @Html.HttpMethodOverride(HttpVerbs.Put) When I submit my form, I get a 404 error from IIS 7.5, saying the static file handler couldn't find the resource. Strangely the same forms work in Cassini, so I think it is something in IIS7.5's setup.
What do I need to do to get IIS 7.5 to handle REST verbs like PUT and DELETE with Asp.Net MVC 3? I have already removed WebDAV and have looked through the handlers but the ones I am modifying seem to do nothing. My current setup is Asp.Net MVC 3, IIS7.5 on Windows 7.
I made a custom handler that derives from MvcHandler. I have my routes using a custom RouteHandler that returns my new handler for GetHttpHandler(), and I override ProcessRequest() in my custom handler. The call to GetHttpHandler is triggering a breakpoint and my handler's constructor is definitely being called, but BeginProcessRequest() is being called on the base MvcHandler instead of ProcessRequest().
Why are the async methods being called when I haven't done anything to call them? I don't want asynchronous handling, and I certainly didn't do anything explicit to get it. My controllers all derive from Controller, not AsyncController.
I don't have the source code with me right now, but I can add it later if needed. I was hoping someone might know some of the reasons why BeginProcessRequest might be called when it's not wanted.
I have an IHttpHandler that I would like to hook into the OutputCache support so I can offload cached data to the IIS kernel. I know MVC must do this somehow, I found this in OutputCacheAttribute:
public override void OnResultExecuting(ResultExecutingContext filterContext) { if (filterContext == null) { throw new ArgumentNullException("filterContext"); }
I have created a server product that is connecting to some social network servers and sending to data which status update etc. The server already authenticated to necessary social networks servers by users who is using this solution.
Actually, I have no problem at this time, but I think I will.
My server will be open a thousands of concurrent request to neccessary servers via Http with C# HttpWebRequest instance. I already know that It's possible to change concurrent request limits with below propery.
ServicePointManager.DefaultConnectionLimit AFAIK, this limit is max 100 evet you set more than 100. So, I will be faced with bottleneck problem with HttpWebRequest even change the DefaultConnectionLimit property of ServicePointManager.
