腾讯 COS 对象存储 - SDK 文件上传对接，示例代码

---

1、SDK

 <dependency> <groupId>com.qcloud</groupId> <artifactId>cos_api</artifactId> <version>5.6.24</version> </dependency> <dependency> <groupId>com.tencentcloudapi</groupId> <artifactId>tencentcloud-sdk-java</artifactId> <version>3.1.62</version><!-- 注：这里只是示例版本号，请获取并替换为 最新的版本号 --> </dependency> 

2、工具类代码

import com.alibaba.fastjson.JSON; import com.qcloud.cos.COSClient; import com.qcloud.cos.ClientConfig; import com.qcloud.cos.auth.BasicCOSCredentials; import com.qcloud.cos.auth.COSCredentials; import com.qcloud.cos.model.ObjectMetadata; import com.qcloud.cos.model.PutObjectRequest; import com.qcloud.cos.model.PutObjectResult; import com.qcloud.cos.region.Region; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.InputStream; import java.util.Objects; import java.util.UUID; /**
 * @author Created by 谭健 on 2020/9/18. 星期五. 14:00.

 */ public class COSUtils { // id 和 密钥  secretKey 这个 private static final String SID = "****"; private static final String SK = "****"; private static final COSCredentials cred = new BasicCOSCredentials(SID, SK); private static final Region region = new Region("ap-nanjing"); private static final ClientConfig clientConfig = new ClientConfig(region); public static final String DOMAIN = "https://public-1301924604.cos.ap-nanjing.myqcloud.com/"; /**
     * 传到 COS
     *
     * @param inputStream 输入流
     * @param key         文件名
     */ public static String upload(InputStream inputStream, String key) { //  生成 cos 客户端。 COSClient cosClient = new COSClient(cred, clientConfig); // 指定要上传到的存储桶 String bucketName = "public-1301924604"; // 指定要上传到 COS 上对象键 if (Objects.isNull(key)) { key = UUID.randomUUID().toString(); } ObjectMetadata metadata = new ObjectMetadata(); PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, key, inputStream, metadata); PutObjectResult putObjectResult = cosClient.putObject(putObjectRequest); System.out.println(JSON.toJSONString(putObjectResult)); return DOMAIN + key; } } 

3、使用示例

 public static void main(String[] args) { // 示例代码 File localFile = new File("C:\\Users\\A-PC\\Desktop\\1.txt"); try { // 返回文件地址 String upload = upload(new FileInputStream(localFile), "1.txt"); System.out.println(upload); } catch (FileNotFoundException e) { e.printStackTrace(); } }
