角动态表单验证

Question

在json的Angular动态中，是这样的

regConfig: FieldConfig[] = [
   {
     type: "input",
     label: "Username",
     inputType: "text",
     name: "name",
     validations: [
       {
         name: "required",
         validator: Validators.required,
         message: "Name Required"
       },
       {
         name: "pattern",
         validator: Validators.pattern("^[a-zA-Z]+$"),
         message: "Accept only text"
       }
     ]
   }

可以很好地进行验证

但是我们正在从后端像这样从json发送响应

regConfig: FieldConfig[] = [
   {
     type: "input",
     label: "Username",
     inputType: "text",
     name: "name",
     validations: [
       {
         name: "required",
         validator: "Validators.required",
         message: "Name Required"
       },
       {
         name: "pattern",
         validator: Validators.pattern("^[a-zA-Z]+$"),
         message: "Accept only text"
       }
     ]
   }

请参阅验证器属性。 所以我的问题是：

有没有办法像这样的验证器从后端RestController发送数据？

或者我们可以像下面这样的验证器来动态处理值：“ Validators.required”

我正在遵循这种示例
