由于缺少OperationFilterContext.ControllerActionDescriptor，解决方案无法编译

Question

我刚创建并下载了一个示例项目。由于引用了ControllerActionDescriptor对象的OperationFilterContext属性，它无法编译：

public class SecurityRequirementsOperationFilter : IOperationFilter
{
    public void Apply(Operation operation, OperationFilterContext context)
    {
        var actionAttrs = context.ControllerActionDescriptor.MethodInfo.GetCustomAttributes(true).ToList();
    }
}

我确实更新了所有NuGet包。 DLL地狱永远不会消失:-(

Answer 1

Swashbuckle.AspNetCore v2.5.0

ControllerActionDescriptor仅出现在Swashbuckle.AspNetCore v2.5.0中。

见：https://github.com/domaindrivendev/Swashbuckle.AspNetCore/commit/c9777021ff3b7bd7900fb259779df8d3cba4e217#diff-e86edb6a6357b96238665ca2b11f5ab8

---

Swashbuckle.AspNetCore v3.0.0+

现在，你只需要：

var controllerAttributes = context.MethodInfo.DeclaringType.GetCustomAttributes(true);
