Hi today I came across during encoding rather unpleasant nuisance. Namely, it concerns an injection through IoC and download the current HttpContext context of the classes that need such session. cookies, etc. As we all know it is difficult to access HttpContext object and it's hard to easily inject. So I decided to write a wrapper to the HttpContext.
HttpContextProvider
Our house will inherit the class IHttpContextProvider. It will be a fundamental variable that will allow us to get into all HttpContextu current parameters. The object will look like this: public class
HttpContextProvider: IHttpContextProviderGenerally nothing particularly odd about this difficult subject. The only one that can arouse the curiosity is a mysterious class of System.Web HttpContextWrapper from the library. This class inherits from HttpContextBase and allows you to get the functionality of the current context. With this solution we have easy access to the container HttpContextu IoC as well as this helps us to test because, as most of you know a false context is quite an unpleasant task.
{public Context System.Web.HttpContextBase
{get {return new HttpContextWrapper (HttpContext.Current);}}
public System.Web.HttpRequestBase
Request
{get {return Context.Request;}}
public System.Web.HttpResponseBase
Response {get {return
Context.Response;}}
public System.Collections.Specialized.NameValueCollection FormOrQueryString
{
get
{
if (Request.RequestType == 'POST') {
return Request.Form;}
return Request.QueryString;
}}}
Session Manager
scribble All of these were associated with wanted to create a facility to manage the user session. The main solution that I wanted to add a strongly typed session handling. SessionManager class looks like this:
public class SessionManager: ISessionManagerbasic class has methods to get and set values \u200b\u200bin the session as well as the abandonment of the session. In addition, I added a method that takes the value TryGet session but when it returns, there is no default value for a given type. During normal sampling method throws an exception NullReferenceException Get what is sometimes undesirable. It is something like we have in the dictionary. However, unfortunately, a collection of sessions is not a dictionary. That's all for today.
{
private IHttpContextProvider _httpContextProvider;
public SessionManager (IHttpContextProvider provider) {
_httpContextProvider = provider;
}
\u0026lt;T> public void Set (string name, T value)
{
_httpContextProvider.Context.Session.Add(name, value);
}
public T Get<T>(string name)
{
return (T)_httpContextProvider.Context.Session[name];
}
public T TryGet<T>(string name)
{
try
{
return (T)_httpContextProvider.Context.Session[name];
}
catch (NullReferenceException e)
{
return default(T);
}
}
public void Abandon()
{
_httpContextProvider.Context.Session.Abandon();
}}
