ASP.NET Core 注册中间件_使用IApplicationBuilder注册中间件

一、ASP.NET Core 注册中间件_使用IApplicationBuilder注册中间件

Use()

app.Use(async (context, next) =>
            {
                await context.Response.WriteAsync("hello world");
                await next.Invoke();
            });


app.Use((next) =>
            {
                return async (context) =>
                {
                    await context.Response.WriteAsync("hello world2");
                    await next(context);
                };
            });

 

绑定上传：

    //绑定WebSocket处理，接收成功后，生成缩略图
    UploadHandle.ServerInfo.SitePath = env.WebRootPath; //使用wwwroot作为根目录
    app.Map("/upload/common", (con) =>
    {
        con.UseWebSockets();//启用webscoket
        con.Use(async (ctx, next) =>
        {
            Receiver _receive = new Receiver(ctx, "upload/images");
            _receive.OnSuccess += (data) =>
            {
            };
            _receive.OnError += (ex) =>
            {
                int i = 10;

            };

            await _receive.DoWork();
            await next.Invoke();
        });
    });
