Determine if ASP.NET application is running locall

问题:

I want to know if there is a recommended way of determining if an asp application is running locally. At the moment I use the Request object and do a string search for localhost or 127.0.0.1 on the server variable but this has several limitations. The biggest one being that the Request object is not always available when I need it.

回答1:

See HttpRequest.IsLocal

bool isLocal = HttpContext.Current.Request.IsLocal;

回答2:

You can check the Request.IsLocal property

回答3:

This worked for me with Application_Start

if (!HostingEnvironment.IsDevelopmentEnvironment)
{
      GlobalFilters.Filters.Add(new RequireHttpsAttribute());
}

To know more about how IsDevelopmentEnvironment is set, please look at the following thread.

In ASP.NET, what determines the value of HostingEnvironment.IsDevelopmentEnvironment?

回答4:

In a MVC view / ASP page / code behind class:

bool isLocal = HttpContext.Current.Request.IsLocal;

In an MVC controller :

bool isLocal = Request.IsLocal;

回答5:

Request.IsLocal is the same as checking for 127.0.0.1 or ::1. See this post: http://forums.asp.net/p/1065813/4081335.aspx.

回答6:

If HttpContext.Current is not null use

HttpContext.Current.Request.IsLocal

Otherwise, for example in the App_Start or before HttpContext.Current is available, you can test

HostingEnvironment.ApplicationPhysicalPath.StartsWith(@"C:\")

or a dedicated disk on your PC.

Another way can be use a constant compilation variable set in production, for example from Azure and visualstudio.com if you use them.

It is dirty, but it works.

Request is not always available in ASP.NET environment?

HttpContext and its properties Request/Response are initialized as soon as the server starts processing the page. So at any place you can execute c# code in your page life cycle you should be able to check the request url.
