[英]HttpWebRequest and Response
I am writing a c# program for HttpRequest
and Response
as below.我正在为
HttpRequest
和Response
编写一个 c# 程序,如下所示。
public string Methods(int id)
{
HttpWebRequest Request = (HttpWebRequest) WebRequest.Create(@"http://172.17.18.16:8082/item/detail/90");
Request.Method = "Get";
WebResponse Response = Request.GetResponse();
IHttpRequest request = (IHttpRequest)Request;
IHttpResponse response = (IHttpResponse)Response;
SetupRequest(request, response, session);
//Request.Method = Method.Get;
string m = request.Method;
TemplateManager mg=new TemplateManager();
ItemController it = new ItemController(mg);
it.Detail();
return m;
}
Here IHttpRequest
and IHttpResponse
are the Interfaces which are already created.这里
IHttpRequest
和IHttpResponse
是已经创建的接口。 I want to assign HttpWebRequest Request
to the interface so that the remaining functionality should happen itself.我想将
HttpWebRequest Request
分配给接口,以便剩余的功能应该自己发生。 I am getting error in casting lines as我在铸造线时遇到错误
Unable to cast object of type 'System.Net.HttpWebRequest' to type 'HttpServer.IHttpRequest'.
无法将“System.Net.HttpWebRequest”类型的 object 转换为“HttpServer.IHttpRequest”类型。
Please help me to find a solution请帮我找到解决方案
Thanks谢谢
These lines are never going to work:这些行永远不会起作用:
IHttpRequest request = (IHttpRequest)Request;
IHttpResponse response = (IHttpResponse)Response;
because neither of them implement the interfaces IHttpRequest
or IHttpResponse
.因为它们都没有实现接口
IHttpRequest
或IHttpResponse
。 To make an inbuilt class implement your own interfaces you will have to extend it (derive a new class from it), I'm not sure exactly why you are trying to do this with these two classes, but typically you would only pass them around as an interface if you wanted to change how they are implemented;要使内置 class 实现您自己的接口,您必须扩展它(从中派生一个新的 class),我不确定您为什么要尝试使用这两个类来执行此操作,但通常您只会将它们传递如果你想改变它们的实现方式,作为一个接口; ie if you wanted to write a replacement for
HttpWebRequest
, or if you were using a dependency injection container (and even this doesn't require interfaces to work).即,如果您想为
HttpWebRequest
编写替代品,或者您正在使用依赖注入容器(甚至这不需要接口来工作)。
