中间件类写法
public class TestMiddleware
{
private readonly RequestDelegate _next;
public TestMiddleware(RequestDelegate next)
{
_next = next;
}
public Task Invoke(HttpContext httpContext)
{
// TO DO
return _next(httpContext);
}
}

注册到宿主上
public static class TestMiddlewareExtensions
{
public static IApplicationBuilder UseTestMiddleware(this IApplicationBuilder builder)
{
return builder.UseMiddleware<TestMiddleware>();
}
}

使用
Startup.cs
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
//app.Use<TestMiddleware>();
app.UseTestMiddleware();
}

内联中间件
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.Use(async (context, next) =>
{
// TO DO
await next();
});
}
