一、ASP.NET Core 註冊中介軟體_使用IApplicationBuilder註冊中介軟體

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);
                };
            });

繫結上傳：

    //繫結WebSocket處理，接收成功後，生成縮圖
    UploadHandle.ServerInfo.SitePath = env.WebRootPath; //使用wwwroot作為根目錄
    app.Map("/upload/common", (con) =>
    {
        con.UseWebSockets();
 
//啟用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();
        });
    });
