Question

我们有一个ASP.NET Web Api应用程序，它使用OAuth Bearer Tokens进行身份验证，我们正在尝试实现请求/响应日志记录。

基本上它的工作原理如下：
1.用户向“/ authenticate”发送请求并接收认证令牌
2.然后，用户将此身份验证令牌用于对公开的API方法的请求

为了将请求记录到公开的API方法，我们使用DelegatingHandler，它完全正常。

但是，DelegatingHandler实施不会捕获对“/ authenticate”发出的请求。

记录令牌请求是否需要不同的方法？

public abstract class MessageHandler : DelegatingHandler
{
    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        var correlationId = Guid.NewGuid();

        var requestInfo = string.Format("{0} {1}", request.Method, request.RequestUri);

        var requestContent = await request.Content.ReadAsByteArrayAsync();

        var context = ((HttpContextBase)request.Properties["MS_HttpContext"]);

        await IncomingMessageAsync(correlationId, request.Method, request.RequestUri, request.Headers, requestContent, 
            context.Request.UserHostAddress, context.Request.IsAuthenticated, context.User.Identity.Name);

        var response = await base.SendAsync(request, cancellationToken);

        byte[] responseMessage;

        responseMessage = await response.Content.ReadAsByteArrayAsync();

        await OutgoingMessageAsync(correlationId, response.StatusCode, response.Headers, responseMessage);

        return response;
    }

    protected abstract Task IncomingMessageAsync(Guid correlationId, HttpMethod requestMethod, Uri requestUri, HttpRequestHeaders requestHeaders, byte[] messageContent, string ipAddress, bool isAuthenticated, string requestMadeByUserName);
    protected abstract Task OutgoingMessageAsync(Guid correlationId, HttpStatusCode statusCode, HttpResponseHeaders responseHeaders, byte[] messageContent);
}

使用OAuth代码进行编辑

[assembly: OwinStartup(typeof(MyApp.Infrastructure.IdentityConfig))]
namespace MyApp.Infrastructure
{
    public class IdentityConfig
    {
        public void Configuration(IAppBuilder app)
        {
            app.CreatePerOwinContext<ApplicationIdentityDbContext>(() => ApplicationIdentityDbContext.Create(ConfigurationDataProvider.MYDBCONNSTRING));
            app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
            app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);

            app.UseOAuthBearerTokens(new OAuthAuthorizationServerOptions
            {
                 Provider = new ApplicationAuthProvider(),
                 AllowInsecureHttp = true,
                 TokenEndpointPath = new PathString("/Authenticate")
            });
        }
    }
}

您正在安装OWIN middleware以在 WebAPI中间件之前发出令牌。

app.UseOAuthBearerTokens(new OAuthAuthorizationServerOptions { Provider = new ApplicationAuthProvider(), AllowInsecureHttp = true, TokenEndpointPath = new PathString("/Authenticate") });

您尝试用来记录请求的DelegatingHandler是Web API middeware的一部分，并且永远不会到达，因为令牌发布中间件处理请求并且不会在管道中进一步调用中间件。

使用以下中间件而不是使用DelegatingHandler，并在令牌中间件之前安装它。

public class RequestLoggerMiddleware { private readonly Func<IDictionary<string, object>, Task> _next; private readonly ILogger _logger; public RequestLoggerMiddleware( Func<IDictionary<string, object>, Task> next, ILogger logger) { _next = next; _logger = logger; } public Task Invoke(IDictionary<string, object> environment) { var context = new OwinContext(environment); _logger.Write($"{context.Request.Method} {context.Request.Uri.AbsoluteUri}"); var result = _next.Invoke(environment); _logger.Write($"Status code: {context.Response.StatusCode}"); return result; } }

要安装中间件，只需在app.Use(typeof (RequestLoggerMiddleware));的{{1}}语句前插入语句app.UseOAuthBearerTokens。

我们如何在ASP.NET Web API中记录身份验证令牌请求
