编写代码过程中不理解的代码可参考上面的文献
首先需要配置你的Program.cs，代码如下：
//在ASP.NET Core应用程序中配置依赖注入容器，将 HttpContextAccessor 注册为一个服务
builder.Services.AddHttpContextAccessor();
//选择使用那种方式来身份验证(Cookie)
builder.Services.AddAuthentication(option =>
{
option.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme; //默认身份验证方案Cookie
option.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
option.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
option.DefaultForbidScheme = CookieAuthenticationDefaults.AuthenticationScheme;
option.DefaultSignOutScheme = CookieAuthenticationDefaults.AuthenticationScheme;
}).AddCookie(CookieAuthenticationDefaults.AuthenticationScheme, option =>
{
option.LoginPath = "/Login/AdminLoginView";//如果没有找到用户信息---身份验证失败--授权也失败了---就跳转到指定的Action
option.AccessDeniedPath = "/Login/AdminLoginView";//访问被拒绝就跳转到指定的Action
});然后开启中间件
// 身份认证中间件
app.UseAuthentication();
app.UseAuthorization(); 创建一个AuthenticationMiddleware.cs类
private readonly RequestDelegate _next;
public AuthenticationMiddleware(RequestDelegate next, IAuthenticationSchemeProvider schemes)
{
_next = next;
Schemes = schemes;
}
public IAuthenticationSchemeProvider Schemes { get; set; }
public async Task Invoke(HttpContext context)
{
// 记录原始路径和原始基路径
context.Features.Set<IAuthenticationFeature>(new AuthenticationFeature
{
OriginalPath = context.Request.Path,
OriginalPathBase = context.Request.PathBase
});
// 如果有显式指定的身份认证方案，优先处理（这里不用看，直接看下面）
var handlers = context.RequestServices.GetRequiredService<IAuthenticationHandlerProvider>();
foreach (var scheme in await Schemes.GetRequestHandlerSchemesAsync())
{
var handler = await handlers.GetHandlerAsync(context, scheme.Name) as IAuthenticationRequestHandler;
if (handler != null && await handler.HandleRequestAsync())
{
return;
}
}
// 使用默认的身份认证方案进行认证，并赋值 HttpContext.User
var defaultAuthenticate = await Schemes.GetDefaultAuthenticateSchemeAsync();
if (defaultAuthenticate != null)
{
var result = await context.AuthenticateAsync(defaultAuthenticate.Name);
if (result?.Principal != null)
{
context.User = result.Principal;
}
}
await _next(context);
}在写登录的地方去使用
/// <summary>
/// 用户登录
/// </summary>
/// <param name="dto"></param>
/// <returns></returns>
/// <exception cref="NotImplementedException"></exception>
public async Task<ResultDto<int>> AdminLogin(LoginDto dto)
{
try
{
var model = await _adminRepository.FindAsync(a => a.AdminAccount == dto.LoginName);
if (model.AdminAccount == null)
{
return new ResultDto<int>
{
code = 0,
data = 2,
msg = "用户不存在",
};
}
bool isCode = Validate2(dto.Id, dto.ValidateCode);
if (!isCode)
{
return new ResultDto<int>
{
code = 0,
data = 3,
msg = "验证码错误"
};
}
if (model.AdminPassword.ToUpper() == dto.LoginPassword.Md5().ToUpper())
{
var identity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme);
identity.AddClaims(new[]
{
new Claim(ClaimTypes.NameIdentifier,model.AdminId.ToString()),//存储登录的角色的AdminId
new Claim(ClaimTypes.Name,model.AdminName),//存储登录的角色的AdminName
});
var principal = new ClaimsPrincipal(identity);
// 登录设置项 比如过期时间
var properties = new AuthenticationProperties
{
ExpiresUtc = DateTimeOffset.UtcNow.AddSeconds(60),
AllowRefresh = true
};
await _httpcontext.HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal, properties);
return new ResultDto<int>
{
code = 0,
data = 1,
msg = "登陆成功"
};
}
else
{
return new ResultDto<int>
{
code = 0,
data = 4,
msg = "密码错误"
};
}
}
catch (Exception)
{
throw;
}
} 最后给你的控制器加上特性就可以了。
