// Endpoint以杭州为例，其它Region请按实际情况填写。
String endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
// 阿里云主账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM账号进行API访问或日常运维，请登录 https://ram.console.aliyun.com 创建RAM账号。
String accessKeyId = "<yourAccessKeyId>";
String accessKeySecret = "<yourAccessKeySecret>";
String bucketName = "<yourBucketName>";
String objectName = "<yourObjectName>";
// 创建OSSClient实例。
OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);
// 生成签名URL。
Date expiration = DateUtil.parseRfc822Date("Thu, 19 Mar 2019 18:00:00 GMT");
GeneratePresignedUrlRequest request = new GeneratePresignedUrlRequest(bucketName, objectName, HttpMethod.PUT);
// 设置过期时间。
request.setExpiration(expiration);
// 设置Content-Type。
request.setContentType("application/octet-stream");
// 添加用户自定义元信息。
request.addUserMetadata("author", "aliy");
// 生成签名URL（HTTP PUT请求）。
URL signedUrl = ossClient.generatePresignedUrl(request);
System.out.println("signed url for putObject: " + signedUrl);
// 使用签名URL发送请求。
File f = new File("<yourLocalFile>");
FileInputStream fin = new FileInputStream(f);
// 添加PutObject请求头。
Map<String, String> customHeaders = new HashMap<String, String>();
customHeaders.put("Content-Type", "application/octet-stream");
customHeaders.put("x-oss-meta-author", "aliy");
PutObjectResult result = ossClient.putObject(signedUrl, fin, f.length(), customHeaders);
// 关闭OSSClient。
ossClient.shutdown();
