# 如何使用筛选条件补全地址
<a name="how-to-complete-address-with-filters"></a>

自动补全 API 支持补全部分输入的地址，从而便于最终用户快速且规范地输入地址。通过使用 `AdditionalFeatures` 参数，您可以自定义响应中提供的信息以满足特定要求。

## 潜在使用案例
<a name="potential-use"></a>
+ **尽可能缩减数据以提高成本效益：**在预计会有后续查询的情况下，仅请求必要的地址组成部分，这样可以减小响应的大小并降低数据传输成本。
+ **包含必要的详细信息以便直接使用：**检索全面的地址信息，从而无需进行其他查询。

## 示例
<a name="autocomplete-address-examples"></a>

### 使用国家/地区筛选条件补全地址
<a name="autocomplete-country-filter"></a>

本示例应用国家/地区筛选条件来优化结果，从而让用户输入的地址的标准化格式能够准确补全表单字段。

### 使用其他数据补全地址
<a name="autocomplete-additional-data"></a>

本示例返回其他数据，使得无需后续查询，即可使用返回的地址详细信息。对于该使用案例而言，`Core` 附加功能集已经足够了。
