我正在使用所有最新的Nuget Packages for ASP.NET Core Rest Server with Swagger
我无法找到如何修复底部描述的错误（也有代码）。我试过：

• 正在添加Route属性
• 向HttpGet属性添加路径
• 删除参数名称

我总是得到下面描述的错误：
内部服务器错误...
在“输出”窗口中：
“Swashbuckle.AspNetCore.SwaggerGen.SwaggerGeneratorException：操作的Ambient HTTP方法-CommandDER.WebService.Controllers.GensetController.GetGensetsByMicrogridId（CommandDER.WebService）。操作需要Swagger/OpenAPI 3.0的显式HttpMethod绑定”

问题

• 为什么Route和HttpGet似乎提供相同的东西？=>在StackOverflow找到答案，我应该使用HttpGet进行GET操作。
• 为什么这两种方式似乎都不能消除动作的歧义？

错误代码：
