.NET Core 和框架通过 SystemWebAdapter 共享特定的会话变量

Question

我们的 ASP.NET Webforms 项目有许多会话变量。根据

SystemWebAdapter

，我需要在

AddJsonSessionSerializer

中按

Application_Start

列出它们。

我是否可以将它们限制为仅在 .NET Core 项目中使用？

我尝试不列出所有这些并收到此错误：“未知的会话密钥

这是包含两个会话变量的 ASP.NET 代码快照：

Company

和

Employee

。但只有

Employee

设置为分享

protected void Application_Start(object sender, EventArgs e)
{
    SystemWebAdapterConfiguration.AddSystemWebAdapters(this)
        .AddJsonSessionSerializer(options => {
            options.RegisterKey<ArrayList>("Employee");
        })
        .AddRemoteAppServer(
            options => {
                options.ApiKey = "4ffb49b3-2aa3-40b3-96ca-1b5331aab2dc";
            }
        ).AddSessionServer();
}

protected void Session_Start(object sender, EventArgs e)
{
    System.Web.HttpContext.Current.Session["Company"] = "ABC";
    System.Web.HttpContext.Current.Session["Employee"] = "John";
}

这是

program.cs

：

using Core;
using System.Collections;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddControllers();
builder.Services.AddTransient<GlobalExceptionHandlerMiddleware>();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

builder.Services.AddSystemWebAdapters()
    .AddJsonSessionSerializer(options => {
        options.RegisterKey<ArrayList>("Employee");
    })
    .AddRemoteAppClient(options => {
        options.RemoteAppUrl = new Uri("http://192.168.56.1");
        options.ApiKey = "4ffb49b3-2aa3-40b3-96ca-1b5331aab2dc";
    }).AddSessionClient();

var app = builder.Build();

app.UseSwagger();
app.UseSwaggerUI();
app.UseMiddleware<GlobalExceptionHandlerMiddleware>();
app.UseAuthorization();
app.UseSystemWebAdapters();
app.MapControllers();
app.Run();

谢谢

在我的本地测试后，我发现您似乎缺少

RequireSystemWebAdapterSession

，也许您在控制器中使用

[Session]

属性。并且您的网络表单应用程序中没有

Company

Register Key

信息。

这是适合您的工作示例。
