如何从Web请求的URL中确定对象绑定的值?

本文关键字：对象 绑定 URL Web 请求 | 更新日期: 2023-09-27 18:12:56

大致如下:

<<p> Api控制器/strong> 
public class MyController : ApiController
{
    public MyController(IServiceThatNeedsPrinicipal myService)
    {
    }
}

MyService 

public class MyService: IServiceThatNeedsPrinicipal 
{
    public MyService(IMyPrincipal myService)
    {
    }
}

IMyPrincipal 

public interface IMyPrincipal : IPrincipal {}

这个自托管网站将得到一个POST请求，如:

localhost:9005/Start?UserId=1

我想做的是:

this.Bind<IMyPrincipal>().ToMethod(c =>
{
    int userId = /* Get UserId from Request -- How do I do this inside a NinjectModule? */
    IMyPrincipal mp = CodeToGetMyPrincipalFromUserId(userId); /* I know how to do this */
    return mp;
});

I tried: 

var request = HttpContext.Current.Items["MS_HttpRequestMessage"] as HttpRequestMessage;
var queryPairs = request.GetQueryNameValuePairs();

通过queryPairs，但是在运行时HttpContext.Current是null。

任何想法-我如何从url中获得值并在我的Ninject模块中访问?

提前感谢!

如何从Web请求的URL中确定对象绑定的值?

我希望这是我想要的功能。似乎有效。(当然它很丑。)

我创建了一个带有静态属性的类:

public class RequestMessage
{
    public static HttpRequestMessage Contents { get; set; }
}

然后我添加了一个DelegatingHandler来设置它

public class RequestMessageHandler : DelegatingHandler
{
    protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        RequestMessage.Contents = request;
        return base.SendAsync(request, cancellationToken);
    }
}

并注册:

config.MessageHandlers.Add(new RequestMessageHandler());

并将我的代码改为:

var request = RequestMessage.Contents;
