# 如何补全地址
<a name="how-to-complete-address"></a>

自动补全 API 使您能够补全部分输入的地址，从而为最终用户提供标准化输入，并提高数据输入效率。

## 潜在使用案例
<a name="potential-use"></a>
+ **在结账时补全地址：**当客户在结账表单中输入信息时，帮助其更准确、更快速地输入地址。
+ **特定于国家/地区的地址补全：**将建议限制在特定国家/地区，以确保合规性或与用户所在位置的相关性。

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

### 使用尽可能少的数据补全地址
<a name="autocomplete-minimal-data"></a>

在本示例中，只返回少量数据，以使响应内容简洁且具有成本效益。以后可以使用 PlaceId 通过 GetPlace API 检索完整的地点详细信息。

```
{
  "QueryText": "100 McCullum Rd"
}
```

#### [ Sample response ]

```
{
    "ResultItems": [
        {
            "PlaceId": "<Redacted>",
            "PlaceType": "PointAddress",
            "Title": "United Kingdom, E3 5JB, London, 100 McCullum Road"
        }
    ],
    "QueryRefinements": []
}
```
