【问题描述】：

{
"visibleFields": {
  "design.content.buttons.action.type": {
    "SHOW_CLOSE": true,
    "URL": true,
    "CALL_PHONE": true
  },
  "design.content.formFields": false,
  "success": false,
  "design.appearance.closeButtons": true,
  "design.appearance.backgroundOverlay": true,
  "design.appearance.button": true,
  "design.content.privacyPolicy": false,
  "design.content.wheel": false,
  "design.appearance.formFields": false,
  "design.content.description": true,
  "design.appearance.customCss": true,
  "design.content.headline": true,
  "design.appearance.displayEffect": true,
  "design.layout.floatingbar": true,
  "design.layout": true,
  "design.appearance.body": true,
  "design.content.buttons": true,
  "design.content.images": false
}}

我有上面的 json 结构。我想使用 ref 获得“visibleFields.design.content.images”，但它不起作用。通常我可以像这样使用“visibleFields ['design.content.images']”来访问它，但我无法在架构中实现它。我该如何解决这个问题？

images: Joi.when(Joi.ref('...visibleFields.design.content.images'), {
      is: false,
      then: Joi.array().length(0),
      otherwise: Joi.array().items(
        Joi.object().keys({
          type: Joi.string(),
          label: Joi.string(),
          backgroundColor: Joi.string(),
          size: Joi.number().integer(),
          horizontal: Joi.number().integer(),
          vertical: Joi.number().integer(),
          repeatMode: Joi.string(),
          hide: Joi.boolean(),
          value: Joi.string().uri(),
        }),
      ),
    })

【解决方案1】：

您可以使用{ seperator: false } 选项删除. 分隔符

images: Joi.when(Joi.ref('...visibleFields.design.content.images', { seperator: false }), {
      is: false,
      then: Joi.array().length(0),
      otherwise: Joi.array().items(
        Joi.object().keys({
          type: Joi.string(),
          label: Joi.string(),
          backgroundColor: Joi.string(),
          size: Joi.number().integer(),
          horizontal: Joi.number().integer(),
          vertical: Joi.number().integer(),
          repeatMode: Joi.string(),
          hide: Joi.boolean(),
          value: Joi.string().uri(),
        }),
      ),
    })
