.net webapiSwagger启用ApiKey身份验证

直接在SwaggerConfig中设置请求头，这里请求头用的默认值apiKey，也可以自己定义一个

private const string swaggerApikey = "Authorization";

GlobalConfiguration.Configuration
.MessageHandlers.Add(new SwaggerMessageHandler());

 GlobalConfiguration.Configuration 
                .EnableSwagger(c =>
                    {

                        c.ApiKey(swaggerApikey).Description("Filling bearer token here")
                        .Name("Bearer")
                        .In("header");
                      

                    })
                .EnableSwaggerUi(c =>
                    {
                       
                        c.EnableApiKeySupport(swaggerApikey, "header");  
                    }); 

 internal class SwaggerMessageHandler : DelegatingHandler
        {
            protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
            {
                if (request.RequestUri.LocalPath.Equals("/swagger/docs/v1"))
                {
                    var apikey = request.Headers.FirstOrDefault(x => x.Key.Equals(swaggerApikey)).Value?.FirstOrDefault();
                    if (!"apikey".Equals(apikey))
                        return Task.FromResult(new HttpResponseMessage(HttpStatusCode.Forbidden));
                }
                return base.SendAsync(request, cancellationToken);
            }
        }
