asp.net core ActionExecutedContext 获取Request.Body内容
实体类：
public class ApiActionDescriptorModel:ICloneable

public ApiParameterDescriptorModel[] Parameters { get; set; }

}
在startup中注册：
app.Use(next => new RequestDelegate(
async context =>
{
context.Request.EnableBuffering();
await next(context);
}
));
就可以在请求之后获取到请求体了。
