1、通过NuGet安装MiniProfiler

2、通过Nuget安装MiniProfiler.EF6

3、通过Nuget安装Swashbuckle

 

 4、添加web.config配置，添加到<handlers>节点下面

<add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" 
type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" 
preCondition="integratedMode" />

5、在 Global.asax中添加

protected void Application_BeginRequest()
{
    MiniProfiler.Start();
}
protected void Application_EndRequest()
{
    MiniProfiler.Stop();
}

6、添加InjectMiniProfiler类，然后在App_Start/SwaggerConfig.cs中的EnableSwagger中添加 c.DocumentFilter<InjectMiniProfiler>();

public class InjectMiniProfiler : IDocumentFilter
 {
     public void Apply(SwaggerDocument swaggerDoc, SchemaRegistry schemaRegistry, IApiExplorer apiExplorer)
     {
         swaggerDoc.info.contact = new Contact()
         {
             name = MiniProfiler.RenderIncludes().ToHtmlString()
         };
     }
 }

7、添加SwaggerUiCustomization.js，并且右键该文件修改其属性中的【生成操作】为【嵌入的资源】

//Create a mini profiler script tag with the right properites 
var MiniProfiler = $('#api_info > div:nth-child(3)').text();
const attributes = [
    'src', 'data-version', 'data-path', 'data-current-id', 'data-ids',
    'data-position', 'data-trivial', 'data-children', 'data-max-traces', 'data-controls',
    'data-authorized', 'data-toggle-shortcut', 'data-start-hidden', 'data-trivial-milliseconds'
];
var GetAttr = function (input, attributeName) {
    const myRegexp = attributeName + '="(.*?)"';
    const re = new RegExp(myRegexp, "g");
    const match = re.exec(input);
    return match[1];
}
var s = document.createElement("script");
s.type = "text/javascript";
s.id = "mini-profiler";
s.async = true;
for (var i = 0; i < attributes.length; i++) {
    var element = attributes[i];
    s.setAttribute(element, GetAttr(MiniProfiler, element));
}
document.body.appendChild(s);
// Remove injected tag from view 
$('#api_info > div:nth-child(3)').text('');

8、给swaggerconfig.cs添加

string resourceName2 = thisAssembly.FullName.Substring(0, thisAssembly.FullName.IndexOf(",")) + ".Scripts.swaggerui.SwaggerUiCustomization.js";
 c.InjectJavaScript(thisAssembly, resourceName2);

9、添加WebApiProfilingActionFilter类

public class WebApiProfilingActionFilter : ActionFilterAttribute
    {
        public const string MiniProfilerResultsHeaderName = "X-MiniProfiler-Ids";

        public override void OnActionExecuted(HttpActionExecutedContext filterContext)
        {
            var MiniProfilerJson = JsonConvert.SerializeObject(new[] {MiniProfiler.Current.Id});
            filterContext.Response.Content.Headers.Add(MiniProfilerResultsHeaderName, MiniProfilerJson);
        }
    }

10、往SwaggerUiCustomization.js文件中添加代码window.angular=true;

11、在WebApiConfig.cs中注册这个Filterconfig.Filters.Add(new WebApiProfilingActionFilter());

12、将【项目】-【属性】-【生成】-【输出】-XML文档文件 勾上
