从头开始创建一个股票 MVC 项目，并为 Auth 选择了个人用户帐户。
启动.Auth.cs
public partial class Startup {
// For more information on configuring authentication, please visit http://go.microsoft.com/fwlink/?LinkId=301864
public void ConfigureAuth(IAppBuilder app) {
// Configure the db context, user manager and signin manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
// Configure the sign in cookie
app.UseCookieAuthentication(new CookieAuthenticationOptions {
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Account/Login"),
Provider = new CookieAuthenticationProvider {
// Enables the application to validate the security stamp when the user logs in.
// This is a security feature which is used when you change a password or add an external login to your account.
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
validateInterval: TimeSpan.FromMinutes(30),
regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
},
ExpireTimeSpan = TimeSpan.FromDays(7)//<-- I just added this.
});
//...code removed for brevity
}
}
// Summary:
// Controls how much time the cookie will remain valid from the point it is
// created. The expiration information is in the protected cookie ticket. Because
// of that an expired cookie will be ignored even if it is passed to the server
// after the browser should have purged it
public TimeSpan ExpireTimeSpan { get; set; }
项目中没有其他任何更改，默认模板提供了所需的一切。
更新
根据评论，您始终可以将其添加为web.config中的应用程序设置并用于ConfigurationManager访问它。这样就可以修改它而无需重新编译代码。
var expireTimeSpan = TimeSpan.FromDays(7);//the default
var setting = ConfigurationManager.AppSettings["ApplicationCookieExpireTimeInDays"];
if (setting != null) {
var days = 0;
if (int.TryParse(setting, out days)) {
expireTimeSpan = TimeSpan.FromDays(days);
}
}
// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
// Configure the sign in cookie
app.UseCookieAuthentication(new CookieAuthenticationOptions {
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Account/Login"),
Provider = new CookieAuthenticationProvider {
// Enables the application to validate the security stamp when the user logs in.
// This is a security feature which is used when you change a password or add an external login to your account.
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
validateInterval: TimeSpan.FromMinutes(30),
regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
},
ExpireTimeSpan = expireTimeSpan
});
web.config将保存设置的位置。
<appSettings>
<add key="webpages:Version" value="3.0.0.0" />
<add key="webpages:Enabled" value="false" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
<add key="ApplicationCookieExpireTimeInDays" value="14" />
