我似乎在兜圈子，进入调试模式似乎根本没有帮助。查看成员的控制器和模型，我看不到任何重复的签名（下面的代码块）并且 ajax 调用（JQuery）看起来对我来说很容易找到。如果有人能指出正确的方向，我将不胜感激。
我可以看到正在对 API 进行调用，并且它返回代码 500，完整错误如下。
我还尝试过清理、重建、硬清除缓存、重新启动应用程序池以及重新启动我正在运行的计算机。主要是为了尽可能多地杀死稻草。
我得到的完整错误是
{
"Message": "An error has occurred.",
"ExceptionMessage": "Multiple actions were found that match the request: \r\nGet on type Portal.api.MembersController\r\nGet on type Portal.api.MembersController",

您定义了两个 Get 方法，但没有为它们指定不同的路由：
我会用这样的东西：
// GET api/members
[HttpGet]
[Route("")]
public IHttpActionResult Get()
{
// Implementation for a generic Get request
return Ok("Generic GET response");
}
// GET api/members/{id}
[HttpGet]
[Route("{id}")]
public JsonResult<string> GetById(object id)
{
// insert your code here.....
}
