No constructor was found that had all the dependencies satisfied

I'm trying to update plugin from version 3.90 to 4.0 but when I try to install it I get this error:

"No constructor was found that had all the dependencies satisfied."

"Nop.Core.NopException: No constructor was found that had all the dependencies satisfied. ---> Autofac.Core.Registration.ComponentNotRegisteredException: The requested service 'System.Web.HttpContextBase' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

Can someone help me with this?

Thanks,

Hello,
You can't use

 System.Web.HttpContextBase httpContext

in Asp.Net Core (nopCommerce 4.0) in Constructor.

Please use

 "IHttpContextAccessor _httpContextAccessor"

So your code will look like

using Microsoft.AspNetCore.Http.Features;
...
...
...

 private readonly IHttpContextAccessor _httpContextAccessor;

...
...
 public YourService(IHttpContextAccessor httpContextAccessor)
        {
          
            this._httpContextAccessor = httpContextAccessor;
        }

This will help you.

Same issue

Thanks on your answer. I made a change and now I have another problem in this lines:

1. var licencePath = _httpContextAccessor.Server.MapPath("~/Plugins/PluginName/Text.txt");

2. var currentUrl = _httpContextAccessor.Request.Url != null ? _httpContextAccessor.Request.Url.Host.Replace("www.", "") : null;

Error 1: IHttpContextAccessor does not contain definition for 'Server'

Error 2: IHttpContextAccessor does not contain definition for 'Request'


Do you have any suggestion?

_httpContextAccessor doesn't support Server class.
You can use something like

private readonly IHostingEnvironment _hostingEnvironment;
and  
_hostingEnvironment.ContentRootPath + "\\Plugins\\PluginName\\Text.txt";

Hope it will work.

For get host value use

_httpContextAccessor.HttpContext.Request.Host

Thank you for your answers. It helped me a lot.
