使用实体服务 API 进行过滤

¥Filtering with the Entity Service API

提醒

Strapi v5 中的实体服务 API 已弃用。请考虑改用 文档服务 API。

¥The Entity Service API is deprecated in Strapi v5. Please consider using the Document Service API instead.

实体服务 API 能够过滤通过 findMany() 方法找到的结果。

¥The Entity Service API offers the ability to filter results found with its findMany() method.

结果使用接受 逻辑运算符 和 属性运算符 的 filters 参数进行过滤。每个运算符都应以 $ 为前缀。

¥Results are filtered with the filters parameter that accepts logical operators and attribute operators. Every operator should be prefixed with $.

使用各种 API 进行深度过滤

有关如何使用各种 API 进行深度过滤的示例，请参阅 这篇博客文章。

¥For examples of how to deep filter with the various APIs, please refer to this blog article.

逻辑运算符​

¥Logical operators

$and​

所有嵌套条件必须为 true。

¥All nested conditions must be true.

示例

¥Example



const entries = await strapi.entityService.findMany('api::article.article', {


  filters: {
    $and: [
      {
        title: 'Hello World',
      },
      {
        createdAt: { $gt: '2021-11-17T14:28:25.843Z' },
      },
    ],
  },
});

当传递具有嵌套条件的对象时，将隐式使用 $and：

¥$and will be used implicitly when passing an object with nested conditions:



const entries = await strapi.entityService.findMany('api::article.article', {


  filters: {
    title: 'Hello World',
    createdAt: { $gt: '2021-11-17T14:28:25.843Z' },
  },
});

$or​

一个或多个嵌套条件必须为 true。

¥One or many nested conditions must be true.

示例

¥Example



const entries = await strapi.entityService.findMany('api::article.article', {


  filters: {
    $or: [
      {
        title: 'Hello World',
      },
      {
        createdAt: { $gt: '2021-11-17T14:28:25.843Z' },
      },
    ],
  },
});

$not​

否定嵌套条件。

¥Negates the nested conditions.

示例

¥Example



const entries = await strapi.entityService.findMany('api::article.article', {


  filters: {
    $not: {
      title: 'Hello World',
    },
  },
});
注意

$not 可用作：

¥$not can be used as:

  • 逻辑运算符（例如在 filters: { $not: { // conditions… }} 中）

    ¥a logical operator (e.g. in filters: { $not: { // conditions… }})

  • 属性运算符（例如在 filters: { attribute-name: $not: { … } } 中）。

    ¥an attribute operator (e.g. in filters: { attribute-name: $not: { … } }).

提示

$and、$or 和 $not 运算符可嵌套在另一个 $and、$or 或 $not 运算符内。

¥$and, $or and $not operators are nestable inside of another $and, $or or $not operator.

属性运算符​

¥Attribute Operators

提醒

根据数据库的实现，使用这些运算符可能会给出不同的结果，因为比较是由数据库而不是 Strapi 处理的。

¥Using these operators may give different results depending on the database's implementation, as the comparison is handled by the database and not by Strapi.

$not​

否定嵌套条件。

¥Negates the nested condition(s).

示例

¥Example



const entries = await strapi.entityService.findMany('api::article.article', {


  filters: {
    title: {
      $not: {
        $contains: 'Hello World',
      },
    },
  },
});

$eq​

¥Attribute equals input value.

示例

¥Example



const entries = await strapi.entityService.findMany('api::article.article', {


  filters: {
    title: {
      $eq: 'Hello World',
    },
  },
});

$eq 可以省略：

¥$eq can be omitted:



const entries = await strapi.entityService.findMany('api::article.article', {


  filters: {
    title: 'Hello World',
  },
});

$eqi​

属性等于输入值（不区分大小写）。

¥Attribute equals input value (case-insensitive).

示例

¥Example



const entries = await strapi.entityService.findMany('api::article.article', {


  filters: {
    title: {
      $eqi: 'HELLO World',
    },
  },
});

$ne​

属性不等于输入值。

¥Attribute does not equal input value.

示例

¥Example



const entries = await strapi.entityService.findMany('api::article.article', {


  filters: {
    title: {
      $ne: 'ABCD',
    },
  },
});

$nei​

属性不等于输入值（不区分大小写）。

¥Attribute does not equal input value (case-insensitive).

示例

  },
});

传递值数组时可以省略 $in：

  filters: {
    title: ['Hello', 'Hola', 'Bonjour'],
  },
