# S3 API Usage

## 使用示例

### S3 API 操作

<details>

<summary>AWS CLI</summary>

您可以使用 [AWS 命令行接口](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-welcome.html) 向 Alluxio S3 API 发送 S3 API 请求。 请注意，您必须提供 `--endpoint`参数来指定 Alluxio S3 REST API 的位置，并包含服务器的基本 URI。 端点格式为 `--endpoint "http://{alluxio.worker.web.hostname}:{alluxio.worker.rest.port}/"`。

如涉及 `授权` 标头操作，您可能需要先[配置 AWS 凭证](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html)。

* 有关 Alluxio 如何使用该标头的详细信息，请参阅[授权标头](https://documentation.alluxio.io/ee-ai-cn/ai-3.4/reference/pages/V4ROSjEUxIYMEulXSfoL#全局请求标头)

```console
$ aws configure --profile alluxio-s3
AWS Access Key ID [None]: {user}
AWS Secret Access Key [None]: {dummy value}
Default region name [None]:
Default output format [None]:
```

</details>

<details>

<summary>REST Clients</summary>

您可以直接使用任何 HTTP client 向 Alluxio S3 API 发送 S3 API 请求。 基本 URI 为 `/`；请求应指向 `http://{alluxio.worker.web.hostname}:{alluxio.worker.rest.port}/`。

目前，Alluxio S3 API 不存在access key和secret key验证。 因此，[授权标头](https://documentation.alluxio.io/ee-ai-cn/ai-3.4/reference/pages/V4ROSjEUxIYMEulXSfoL#全局请求标头)仅用于指定执行请求的目标用户。 The header follows the [AWS Signature Version 4](https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-auth-using-authorization-header.html) format.

```console
$ curl -i -H "Authorization: AWS4-HMAC-SHA256 Credential=testuser/... SignedHeaders=... Signature=..." ...
```
