aspnet zero Swagger 不出現Authorize按鈕的解決辦法

aspnet zero的Swagger默認沒有Authorize 按鈕，這樣測試起來很不方便，經過一番操作，終於成功解決了。

其實比較簡單，只要在web.Host項目里的startup.cs里的代碼添加一些代碼就可以了：

原來的代碼：

 services.AddSwaggerGen(options =>
            {
                options.SwaggerDoc("v1", new Info { Title = "FlightProxyFee API", Version = "v1" });
                options.DocInclusionPredicate((docName, description) => true);
}

　　新增加代碼：

 services.AddSwaggerGen(options =>
            {
                options.SwaggerDoc("v1", new Info { Title = "FlightProxyFee API", Version = "v1" });
                options.DocInclusionPredicate((docName, description) => true);

                //新增加代碼
                options.AddSecurityDefinition("Bearer", new ApiKeyScheme
                {
                    Description = "JWT Authorization header using the Bearer scheme. Example: \"Authorization: Bearer {token}\"",
                    Name = "Authorization",
                    In = "header",
                    Type = "apiKey"
                });
            });
