# 文件名模板

默认情况下，传送到您的云存储的结果文件使用 `{{ job_id }}.{{ extension }}`  命名模板（例如， `7346445033316311041.json`）。您可以为传送到您的云存储的结果指定自定义文件命名模板。 

您可能想这样做的原因如下：

* 结果文件名可以更具信息性
* 结果可以自动组织到不同的目录中。

## 模板变量

您可以在创建任务时使用您提供的任何输入参数，以及来自 `job_info` 对象（位于结果底部）的任何变量，作为文件命名模板的一部分。

## 用法

{% stepper %}
{% step %}

#### 示例 1：带有多个变量的自定义文件名

将结果写入 `oxylabs.test/google_search_test_7336001481897673729.json`

```json
{
    "source": "google_search",
    "query": "test",
    "storage_type": "s3",
    "storage_url": "oxylabs.test/{{ source }}_{{ query }}_{{ job_id }}.{{ extension }}"
}
```

{% endstep %}

{% step %}

#### 示例 2：目录组织

将结果写入 `oxylabs.test/google_search/7336001481897673729.json`

```json
{
    "source": "google_search",
    "query": "test",
    "storage_type": "s3",
    "storage_url": "oxylabs.test/{{ source }}/"
}
```

{% endstep %}

{% step %}

#### 示例 3：带有自定义文件名的自定义目录

将结果写入 `oxylabs.test/google_search/oxylabs_test_7336001481897673729.json`

```json
{
    "source": "google_search",
    "query": "test",
    "storage_type": "s3",
    "storage_url": "oxylabs.test/{{ source }}/oxylabs_{{ query }}_{{ job_id }}.{{ extension }}"
}
```

{% endstep %}
