2.java后端上传文件

// 访问域名
String endpoint = "oss-cn-beijing.aliyuncs.com";

// 身份请求ID
String accessKeyId = "阿里云OSS申请";

// 访问密钥
String secretAccessKey = "阿里云OSS申请";

// 存储空间
String bucket = "阿里云OSS申请";

// 本地文件地址
String path = "D:\\image\\test.png";

// 将要上传到的oss路径
String dir = "data/2018/09/29/";

File file = new File(path);
// 生成随机文件名
String uuid = UUID.randomUUID().toString();

String fileName = file.getName();

// 文件名后缀
String suffix = fileName.substring(fileName.lastIndexOf("."));

// 创建OSS客户端
OSSClient ossClient = new OSSClient(endpoint, accessKeyId, secretAccessKey);

// 上传OSS
PutObjectResult result = ossClient.putObject(bucket, dir + uuid + suffix, file);

String eTag = result.getETag();
System.out.println("上传成功, eTag = " + eTag);

ossClient.shutdown();
