使用天翼云對象存儲服務(wù)

本文介紹如何使用天翼云對象存儲服務(wù)

安全憑證

在注冊天翼云賬號之后，進(jìn)入控制臺，創(chuàng)建秘鑰，拿到AccessKeyID和SecretAccessKey用于訪問對象存儲API

下載SDK

在官網(wǎng)選擇對于的jar包https://www.ctyun.cn/h5/help2/10000101/10001740

POM文件配置

在pom.xml中加入以下配置

cn.ctyun

oos-sdk

6.5.0

system

jar

${project.basedir}/src/main/resources/lib/oos-sdk-6.5.0.jar

commons-httpclient

@Bean

public AmazonS3 oosClient() {

ClientConfiguration clientConfig = new ClientConfiguration();

//設(shè)置連接的超時(shí)時(shí)間，單位毫秒

clientConfig.setConnectionTimeout(30 * 1000);

//設(shè)置 socket 超時(shí)時(shí)間，單位毫秒

clientConfig.setSocketTimeout(30 * 1000);

clientConfig.setProtocol(Protocol.HTTP); //設(shè)置 http

//設(shè)置 V4 簽名算法中負(fù)載是否參與簽名，關(guān)于簽名部分請參看《OOS 開發(fā)者文檔》

S3ClientOptions options = new S3ClientOptions();

options.setPayloadSigningEnabled(true);

// 創(chuàng)建 client

AmazonS3 oosClient = new AmazonS3Client(

new PropertiesCredentials(accessKey,

secretKey), clientConfig);

// 設(shè)置 endpoint

oosClient.setEndpoint(endpoint);

//設(shè)置選項(xiàng)

oosClient.setS3ClientOptions(options);

return oosClient;

}

}

創(chuàng)建Bucketpublic void createBucket(String bucketName) {

Bucket bucketInfo = ossClient.createBucket(bucketName,"ChengDu","ShenYang");

}

查詢Bucketpublic void listBuckets() {

List listBuckets = ossClient.listBuckets();

for (Bucket bucketInfo : listBuckets) {

System.out.println("listBuckets:"

+ "\t Name:" + bucketInfo.getName()

+ "\t CreationDate:" + bucketInfo.getCreationDate());

}

}

刪除Bucketpublic void deleteBucket(String bucketName) {

ossClient.deleteBucket(bucketName);

}

上傳文件public String uploadFile(InputStream inputStream, String fileName) {

String key = generateKey(fileName);

PutObjectRequest request = new PutObjectRequest(bucketName, key, inputStream, null);

request.setStorageClass(StorageClass.ReducedRedundancy);

PutObjectResult result = ossClient.putObject(request);

URL url = ossClient.generatePresignedUrl(new GeneratePresignedUrlRequest(bucketName, key));

return String.valueOf(url);

}

刪除文件public void deleteFile(String fileKey) {

ossClient.deleteObject(bucketName, fileKey);

}

獲取文件下載地址public String getDownloadUrl(String fileKey) {

GeneratePresignedUrlRequest request = new

GeneratePresignedUrlRequest(bucketName, fileKey);

URL url = ossClient.generatePresignedUrl(request);

return url.toString();

}
