使用Owin获取远程ip。测试

Question

我使用Owin.Testing作为测试环境。在我的控制器中，我需要从调用者获取远程IP地址。

//in my controller method 
var ip = GetIp(Request); 

的Util

private string GetIp(HttpRequestMessage request) 
     { 
      return request.Properties.ContainsKey("MS_HttpContext") 
         ? (request.Properties["MS_HttpContext"] as HttpContextWrapper)?.Request?.UserHostAddress 
         : request.GetOwinContext()?.Request?.RemoteIpAddress; 
     } 

结果属性不包含OwinContext的MS_HttpContext和RemoteIpAddress为空。

是否有任何选项可以获取IP？

找到解决方案。为此使用测试中间件。一切都在你的测试项目：

public class IpMiddleware : OwinMiddleware 
{ 
    private readonly IpOptions _options; 

    public IpMiddleware(OwinMiddleware next, IpOptions options) : base(next) 
    { 
     this._options = options; 
     this.Next = next; 
    } 

    public override async Task Invoke(IOwinContext context) 
    { 
     context.Request.RemoteIpAddress = _options.RemoteIp; 
     await this.Next.Invoke(context); 
    } 
} 

处理程序：

public sealed class IpOptions 
{ 
    public string RemoteIp { get; set; } 
} 

public static class IpMiddlewareHandler 
{ 
    public static IAppBuilder UseIpMiddleware(this IAppBuilder app, IpOptions options) 
    { 
     app.Use<IpMiddleware>(options); 
     return app; 
    } 
} 

测试启动：

public class TestStartup : Startup 
{ 
    public new void Configuration(IAppBuilder app) 
    { 
     app.UseIpMiddleware(new IpOptions {RemoteIp = "127.0.0.1"}); 
     base.Configuration(app);   
    } 
} 

，然后通过TestStartup创建测试服务器：

TestServer = TestServer.Create<TestStartup>();
