.Net Core系列教程（四）—— 基础身份认证
在ASP.NET 4.5及之前的版本，可以使用FormsAuthenticationTicket来做基础身份认证，现在到了.Net Core中，发现原来的FormsAuthenticationTicket不能用了，其实在.Net Core中，依然可以使用基础身份认证，下面是使用方法。因为这是在具体项目中使用的，会多出一些其他的代码，请自行忽略。
1.在Startup.cs文件中，public void ConfigureServices(IServiceCollection services)方法下添加：
services.AddAuthorization();完整代码：
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddApplicationInsightsTelemetry(Configuration);
services.AddOptions();
services.Configure<Models.ConnectionStrings>(Configuration.GetSection("ConnectionStrings"));
services.AddAuthorization(); //Form基础验证
services.AddMvc();
}2.在public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)方法下添加：
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationScheme = "Cookie",
LoginPath = new PathString("/Manage/Login"),
AccessDeniedPath = new PathString("/Manage/Forbidden"),
AutomaticAuthenticate = true,
AutomaticChallenge = true
});完整代码：
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
//Form基础验证
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationScheme = "Cookie",
LoginPath = new PathString("/Manage/Login"),
AccessDeniedPath = new PathString("/Manage/Forbidden"),
AutomaticAuthenticate = true,
AutomaticChallenge = true
});
app.UseApplicationInsightsRequestTelemetry();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseBrowserLink();
}
else
{
app.UseExceptionHandler("/Home/Error");
}
app.UseApplicationInsightsExceptionTelemetry();
app.UseStaticFiles();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}如果发现有报错，添加引用即可。
3.在控制器文件中，登录的方法下，添加：
var claims = new List<Claim>()
{
new Claim(ClaimTypes.Name,login.username)
//,new Claim(ClaimTypes.Email,"emailaccount@microsoft.com")
};
//var userPrincipal = new ClaimsPrincipal(new ClaimsIdentity(claims, "SuperSecureLogin"));
var userPrincipal = new ClaimsPrincipal(new ClaimsIdentity(claims, token));
HttpContext.Authentication.SignInAsync("Cookie", userPrincipal, new AuthenticationProperties
{
ExpiresUtc = DateTime.UtcNow.AddMinutes(20),
IsPersistent = false,
AllowRefresh = false
});在我自己的项目中，完整的Login方法代码：
[HttpPost]
[ModelValidationFilter]
public Models.ResultModel<object> Login(Models.Login login)
{
var result = new Models.ResultModel<object>();
result = _manage.Login(login);
if(result.status)
{//登录成功
string token = result.data.ToString(); //登录成功后生成的token，用于验证登录有效性
var claims = new List<Claim>()
{
new Claim(ClaimTypes.Name,login.username)
//,new Claim(ClaimTypes.Email,"emailaccount@microsoft.com")
};
//var userPrincipal = new ClaimsPrincipal(new ClaimsIdentity(claims, "SuperSecureLogin"));
var userPrincipal = new ClaimsPrincipal(new ClaimsIdentity(claims, token));
HttpContext.Authentication.SignInAsync("Cookie", userPrincipal, new AuthenticationProperties
{
ExpiresUtc = DateTime.UtcNow.AddMinutes(20),
IsPersistent = false,
AllowRefresh = false
});
}
return result;
}4.在需要进行身份验证的控制器或Action上，添加Authorize特性，如：
加在Action上
[Authorize]
public IActionResult Dashboard()或加在Controller上
[Authorize]
public class ManageSystemController : Controller5.取验证信息
var auth = await HttpContext.Authentication.GetAuthenticateInfoAsync("Cookie");
string username = auth.Principal.Identity.Name; //用户名6.注销登录
HttpContext.Authentication.SignOutAsync("Cookie");具体可参考微软官方Demo：How to achieve a basic authorization in ASP.NET Core
