Cookie Login Logout

该示例展示cookie登入登出的相关代码

Startup.cs 配置

MemberController.cs

坑1：使用oauth2.0的方式做的单点登录，将SignOutAsync包装成接口给客户端调用，发现无效原因是使用的cookie验证，客户端调用时，并没有带上cookie，自然就没效，解决办法是从客户端直接跳到单点登录的logout页面

这个时候，浏览器会带上cookie，实现cookie的退出

public void ConfigureServices(IServiceCollection services)
{
    ... 
    
    // 添加cookie认证
    services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
        .AddCookie(m =>
        {
             m.LoginPath = "/member/login";
        }
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IOptions<SenparcWeixinSetting> senparcWeixinSetting, IOptions<SenparcSetting> senparcSetting)
{
    ...
    
    // 注意这里，在UseAuthorization之前添加UseAuthentication
    app.UseAuthentication();
    app.UseAuthorization();
}

[AllowAnonymous]
public IActionResult Login([FromBody] loginArgsModel)
{

    ...
    
    List<Claim> claims = new List<Claim>
    {
    
        new Claim(ClaimTypes.Name, user.username, ClaimValueTypes.String, null),
    };

    var userIdentity = new ClaimsIdentity("Form");
    userIdentity.AddClaims(claims);

    
    var principal = new ClaimsPrincipal(userIdentity);

    
    await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal);
    
    return Redirect("");
}

public IActionResult Logout(string returnUrl)
{
    HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);
    if (string.IsNullOrEmpty(returnUrl) || returnUrl == "/member/logout") returnUrl = "/member";
    return Redirect(returnUrl);
}
