阿里云对象存储上传图片的工具类
package zhangchao;import com.aliyun.oss.ClientException;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.OSSException;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

public class OSSUtils {// OSS阿里云对象存储的AK和SKprivate static final String OSS_AK yourAK;private static final String OSS_SK yourSK;// OSS阿里云对象存储的Bucket名称private static final String OSS_BUCKET_NAME your-files;// Endpoint以华东1杭州为例其它Region请按实际情况填写。private static final String OSS_ENDPOINT https://oss-cn-hangzhou.aliyuncs.com;/*** 上传图片并返回图片URL* return 图片URL*/public static String uploadImage(String imageFilePath) {String result null;// 创建OSSClient实例。OSS ossClient new OSSClientBuilder().build(OSS_ENDPOINT, OSS_AK, OSS_SK);FileInputStream fis null;try {// 创建存储空间。fis new FileInputStream(imageFilePath);String uuid UUID.randomUUID().toString().replaceAll(-, );ossClient.putObject(OSS_BUCKET_NAME, uuid, fis);// 设置URL过期时间为10年 3600l * 1000 * 24 * 365 * 10Date expiration new Date(System.currentTimeMillis() 3600L * 1000L *24L * 365L * 10L);URL url ossClient.generatePresignedUrl(OSS_BUCKET_NAME, uuid, expiration);if (url ! null) {result url.toString();}} catch (OSSException oe) {StringBuilder sb new StringBuilder();sb.append(Caught an OSSException, which means your request made it to OSS, ).append(but was rejected with an error response for some reason.);sb.append(Error Message:).append(oe.getErrorMessage());sb.append(Error Code:).append(oe.getErrorCode());sb.append(Request ID:).append(oe.getRequestId());sb.append(Host ID:).append(oe.getHostId());System.out.println(sb.toString());} catch (ClientException ce) {StringBuilder sb new StringBuilder();sb.append(Caught an ClientException, which means the client encountered ).append(a serious internal problem while trying to communicate with OSS, ).append(such as not being able to access the network.);sb.append(Error Message: ce.getMessage());System.out.println(sb.toString());ce.printStackTrace();} catch (FileNotFoundException e) {e.printStackTrace();} finally {try {if (null ! fis) {fis.close();}} catch (IOException e) {e.printStackTrace();}if (ossClient ! null) {ossClient.shutdown();}}return result;}
}
调用的 main 方法
package zhangchao;public class Main {public static void main(String[] args) {String imgUrl OSSUtils.uploadImage(E:\\ws\\zc\\Java8OSSImg\\src\\main\\resources\\q1.jpg);System.out.println(imgUrl);}
}运行结果这里显示了返回的图片 URL 地址
https://your-files.oss-cn-hangzhou.aliyuncs.com/abc123?Expires2021599742OSSAccessKeyIdyouAKSignaturexxxxxx这个地址没办法用浏览器直接看需要写个HTML来测试一下。
