Qos.Xin.OAuth.WxAuth 1.0.3

微信公众号OAuth2.0认证实现

认证支持两种方式

1. 【静态】支持配置文件中直接配置appId, appSecret进行认证

            services.AddAuthentication("Cookies").
                .AddCookie("ExternalCookie")
                .AddWechat(k =>
                {
	                k.ClientId = "xxx";
	                k.ClientSecret = "xxx";
	                k.SignInScheme = "ExternalCookie";
	                k.Scope.Add("snsapi_userinfo");
	                k.AccessDeniedPath = new PathString("/access_denied");
	                k.ClaimActions.MapJsonKey("nickname", "nickname");
	                k.ClaimActions.MapJsonKey("headimgurl", "headimgurl");
	                k.ClaimActions.MapJsonKey("openid", "openid");
                });

2. 【动态】支持根据授权时传入的参数或者域名动态查询appId,appSecret进行授权

            services.AddAuthentication()
                .AddCookie("WxAuthCookie", k =>
                {

                })
                .AddWechat(k =>
                {
                    k.SignInScheme = "WxAuthCookie";
                    k.Scope.Add("snsapi_userinfo");
                    k.AccessDeniedPath = new PathString("/access_denied");
                    k.ClaimActions.MapJsonKey("nickname", "nickname");
                    k.ClaimActions.MapJsonKey("headimgurl", "headimgurl");
                    k.ClaimActions.MapJsonKey("openid", "openid");
                    k.InitHandler = (sp, ctx) =>
                    {
                        var taskId = ctx.Request.Query["t"];
                        var context = sp.GetRequiredService<DbContext>();
                        var task = context.ShareTask.Where(k => k.TaskCode == taskId).FirstOrDefault();

                        k.ClientId = task.AppId;
                        k.ClientSecret = task.AppSecret;
                        return Task.CompletedTask;
                    };
                });
