我在使用Angular 7中的前端和ASP.NET.Core 2.1中的后端创建Web应用程序中处于中间位置。在服务器端,我想实现一个简单的会话功能。因此,在Startup.cs中,我使用AddDistributedMemoryCache()
,AddSession()
和UseSession()
配置会话。在服务器域中,一切正常。我有会话cookie,可以从控制器,存储库等访问会话。
问题是当我从另一个域(从Angular的前面)调用html方法时。在HtmlRequest中,没有有关cookie会话的信息,因此HttpContext.Session.Id
总是不同的。我可以将My.Cookie的值发送到前端以通过ngx-cookie-service在前端创建cookie吗?然后,此Cookie将自动发送到HtmlRequest中的后端。我如何从后端访问此Cookie?我只能从请求中获取Cookie,而前端的请求没有My.Cookie。还是在前端和后端之间自动交换My.Cookie?
目前,我将自己的静态存储创建为单例服务,但我认为使用ISession
应该是更好的解决方案。
Startup.cs
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
services
.AddCors(options =>
{
options.AddPolicy("MyCorsPolicy", policyBuilder =>
{
policyBuilder
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowCredentials()
.AllowAnyHeader();
});
})
.AddDistributedMemoryCache()
.AddSession(options =>
{
options.IdleTimeout = TimeSpan.FromHours(1);
options.Cookie = new CookieBuilder { Name = "My.Cookie", HttpOnly = false, IsEssential = true, SameSite = SameSiteMode.None };
});
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app
.UseCors("MyCorsPolicy")
.UseSession()
.UseMvc(routes =>
{
routes.MapRoute("default",
"{controller}/{action}",
new { controller = "Home", action = "Index" });
});
}
}

string message = clientSite["message"];
HttpContext.Session.SetString("Message", message);
