How to create your own SharePoint HttpContext

Quick and short. Here's a function that I use to create my own SharePoint HttpContext objects outside the SharePoint websites domain. I hope it is somehow useful to someone out there as well.

    1         /// <summary>

    2         /// Enables a share point call from anywhere by creating your own context.

    3         /// </summary>

    4         /// <param name="siteCollectionUrl">The site collection URL where you want to create the context.</param>

    5         /// <example>

    6         /// EnableSharePointCallByCreatingYourOwnContext("http://mysite.com.au");

    7         /// </example>

    8         private void EnableSharePointCallByCreatingYourOwnContext(string siteCollectionUrl)

    9         {

   10             using (var site = new SPSite(siteCollectionUrl))

   11             {

   12                 using (var web = site.OpenWeb())

   13                 {

   14                     // assumes that context does not exists

   15                     var contextCreated = false;

   16 

   17                     // if it does not exists, then create it

   18                     if (HttpContext.Current == null)

   19                     {

   20                         contextCreated = true;

   21                         // creates a request object for the current web URL

   22                         var request = new HttpRequest(string.Empty, web.Url, string.Empty);

   23 

   24                         // open the pipe to output the http stream

   25                         HttpResponse httpResponse;

   26                         using (var responseWriter = new StringWriter())

   27                         {

   28                             httpResponse = new HttpResponse(responseWriter);

   29                         }

   30 

   31                         // creates the context

   32                         HttpContext.Current = new HttpContext(request, httpResponse);

   33 

   34                         // HttpHandlerSPWeb is a the property name where you must assign the current web

   35                         // in order to associate the newly created context to sharepoint

   36                         if (HttpContext.Current.Items != null)

   37                         {

   38                             HttpContext.Current.Items["HttpHandlerSPWeb"] = web;

   39                         }

   40                     }

   41 

   42                     // ...

   43                     // do whatever you want to do here

   44                     // ...

   45 

   46                     // return the application context to the original state prior the execution

   47                     if (contextCreated)

   48                     {

   49                         HttpContext.Current = null;

   50                     }

   51                 }

   52             }

   53         }

See you later
