天翼云对象存储支持API接口使用，提供详细使用指南和实践操作，包括经典版对象存储的API接口详解。

天翼云对象存储（经典版）概述

天翼云对象存储（经典版）是一款基于云存储技术的高性能、高可靠、可扩展的云存储服务，它提供了一种简单、高效、安全的方式来存储和访问海量数据，用户可以通过API接口实现数据的上传、下载、删除、查询等操作，本文将详细介绍天翼云对象存储（经典版）的使用方法，包括API接口及其应用实践。

天翼云对象存储（经典版）API接口

1、创建存储桶

创建存储桶是使用天翼云对象存储（经典版）的第一步，以下为创建存储桶的API接口：

POST /v1/api/cloudstorage/buckets
Authorization: Bearer <access_token>
Content-Type: application/json
{
  "bucketName": "example-bucket",
  "location": "example-location"
}

bucketName为存储桶名称，location为存储桶所在地域。

2、列举存储桶

列举存储桶的API接口如下：

GET /v1/api/cloudstorage/buckets
Authorization: Bearer <access_token>

3、上传文件

上传文件的API接口如下：

PUT /v1/api/cloudstorage/buckets/{bucketName}/objects
Authorization: Bearer <access_token>
Content-Type: application/octet-stream
<file_data>

bucketName为存储桶名称，file_data为待上传的文件内容。

4、下载文件

下载文件的API接口如下：

GET /v1/api/cloudstorage/buckets/{bucketName}/objects/{objectKey}
Authorization: Bearer <access_token>

bucketName为存储桶名称，objectKey为文件键值。

5、删除文件

删除文件的API接口如下：

DELETE /v1/api/cloudstorage/buckets/{bucketName}/objects/{objectKey}
Authorization: Bearer <access_token>

bucketName为存储桶名称，objectKey为文件键值。

6、查询文件信息

查询文件信息的API接口如下：

GET /v1/api/cloudstorage/buckets/{bucketName}/objects/{objectKey}
Authorization: Bearer <access_token>

bucketName为存储桶名称，objectKey为文件键值。

三、天翼云对象存储（经典版）API接口实践操作

以下以Java语言为例，演示如何使用天翼云对象存储（经典版）API接口进行文件上传、下载、删除和查询操作。

1、获取access_token

需要获取access_token，以下为Java代码示例：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class OAuth2 {
    public static String getAccessToken(String clientId, String clientSecret, String authUrl) {
        try {
            URL url = new URL(authUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            connection.setDoOutput(true);
            String data = "grant_type=client_credentials&client_id=" + clientId + "&client_secret=" + clientSecret;
            connection.getOutputStream().write(data.getBytes("UTF-8"));
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
                String line;
                StringBuilder response = new StringBuilder();
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();
                String accessToken = response.toString().split(""")[7];
                return accessToken;
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
    public static void main(String[] args) {
        String clientId = "your-client-id";
        String clientSecret = "your-client-secret";
        String authUrl = "https://oauth2.189.cn/oauth2.0/token";
        String accessToken = getAccessToken(clientId, clientSecret, authUrl);
        System.out.println("Access Token: " + accessToken);
    }
}

2、文件上传

以下为Java代码示例，演示如何使用天翼云对象存储（经典版）API接口上传文件：

import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class ObjectStorage {
    public static void uploadFile(String bucketName, String objectKey, InputStream inputStream) {
        try {
            URL url = new URL("https://api.cloud.189.cn/v1/api/cloudstorage/buckets/" + bucketName + "/objects");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("PUT");
            connection.setRequestProperty("Authorization", "Bearer " + accessToken);
            connection.setRequestProperty("Content-Type", "application/octet-stream");
            connection.setDoOutput(true);
            byte[] buffer = new byte[1024];
            int length;
            while ((length = inputStream.read(buffer)) != -1) {
                connection.getOutputStream().write(buffer, 0, length);
            }
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                System.out.println("File uploaded successfully!");
            } else {
                System.out.println("Failed to upload file: " + responseCode);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) {
        String bucketName = "example-bucket";
        String objectKey = "example-object";
        String filePath = "path/to/your/file";
        try (InputStream inputStream = new FileInputStream(filePath)) {
            uploadFile(bucketName, objectKey, inputStream);
        } catch (Exception e) {

            URL url = new URL("https://api.cloud.189.cn/v1/api/cloudstorage/buckets/" + bucketName + "/objects/" + objectKey);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Authorization", "Bearer " + accessToken);
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                InputStream inputStream = connection.getInputStream();
                FileOutputStream outputStream = new FileOutputStream(savePath);
                byte[] buffer = new byte[1024];
                int length;
                while ((length = inputStream.read(buffer)) != -1) {
                    outputStream.write(buffer, 0, length);
                }
                outputStream.close();
                inputStream.close();
                System.out.println("File downloaded successfully!");
            } else {
                System.out.println("Failed to download file: " + responseCode);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) {
        String bucketName = "example-bucket";
        String objectKey = "example-object";
        String savePath = "path/to/save/file";
        downloadFile(bucketName, objectKey, savePath);
    }
}

4、文件删除

以下为Java代码示例，演示如何使用天翼云对象存储（经典版）API接口删除文件：

import java.net.HttpURLConnection;
import java.net.URL;
public class ObjectStorage {
    public static void deleteFile(String bucketName, String objectKey) {
        try {
            URL url = new URL("https://api.cloud.189.cn/v1/api/cloudstorage/buckets/" + bucketName + "/objects/" + objectKey);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("DELETE");
            connection.setRequestProperty("Authorization", "Bearer " + accessToken);
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                System.out.println("File deleted successfully!");
            } else {
                System.out.println("Failed to delete file: " + responseCode);
            }
        } catch (Exception e) {

        }
    }
    public static void main(String[] args) {
        String bucketName = "example-bucket";
        String objectKey = "example-object";
        deleteFile(bucketName, objectKey);
    }
}

5、查询文件信息

以下为Java代码示例，演示如何使用天翼云对象存储（经典版）API接口查询文件信息：

                }
                reader.close();
                Map<String, Object> fileInfo = parseJson(response.toString());
                System.out.println("File Info: " + fileInfo);
            } else {
                System.out.println("Failed to query file info: " + responseCode);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    public static Map<String, Object> parseJson(String json) {
        // 解析JSON字符串，返回Map对象
        // ...
        return null;
    }
    public static void main(String[] args) {
        String bucketName = "example-bucket";
        String objectKey = "example-object";
        queryFileInfo(bucketName, objectKey);
    }
}
