## 重大变更描述 {#breaking-change-description}

🌐 Breaking change description

**在 Strapi v4 中**

提供一个浏览器名称来代替默认名称，XX1 表示停止打开浏览器。

🌐 Provider instances (action provider, condition provider, etc…) are built using a provider factory.

这些提供商有一个 `getWhere` 方法，允许你查询符合特定条件的提供商项目并返回它们。

🌐 Those providers have a `getWhere` method allowing you to query provider’s items that match certain conditions and return them.

查询是一个对象，其中键和值与提供程序条目匹配：

🌐 The query was an object where keys and values were matched with the provider entries:

```js
const values = provider.getWhere({ foo: 42, bar: 'baz' });
```

<br/>

**在 Strapi 5 中**

你需要采用更传统的方法，首先获取提供商值，然后使用自定义谓词对其进行过滤：

🌐 You need to adopt a more conventional approach by first getting the provider values, then filtering them using a custom predicate:

```js
const values = provider.values().filter(value => value.foo === 42 && value.bar === 'baz');
```

### 手动操作 {#manual-procedure}

🌐 Manual procedure

如果使用 `getWhere()` 方法，用户需要手动更新他们的代码，可以参考以下示例：

🌐 Users need to manually update their code if using the `getWhere()` method, using the following example as a guide:

**在 Strapi v4 中**

```tsx
const values = provider.getWhere({ foo: 42, bar: 'baz' });
```

<br/>

**在 Strapi 5 中**

```tsx
const values = provider.values().filter(
  value => value.foo === 42 && value.bar === 'baz'
);
```
