【科普】OSS存储的基本操作
1. 服务接口定义
/**
* 文件上传 1:头像 2：显示图片 3：个人封面 :4：基础图片
* @param request
* @param response
* @param uid 用户id
* @param userType 文件上传 1:头像 2：显示图片 3：个人封面 :4：基础图片 0：视频
* @param files 上传的文件对象
* @return
* @throws Exception
*/
@RequestMapping(value = “/upload/base64Code”, method = RequestMethod.POST)
public ResponseVO fileuploadBase64(@RequestBody JSONObject json, HttpServletRequest request, HttpServletResponse response) throws Exception {
String uid = json.optString(“uid”);
String userType = json.optString(“userType”);
String base64Code = json.optString(“base64Code”);
String oldName = json.optString(“oldName”);
String suffix = json.optString(“suffix”);
//获取当前登陆用户
if(StringUtils.isEmpty(uid)){
return CloudResponseCode.buildEnumResponseVO(CloudResponseCode.USER_ID_NOT_NULL, null);
}
//上传文件新名字
String newName = String.valueOf(new Date().getTime());
String fileKey = CloudConstant.VITAL_USER_INFO_PATH + uid + “/” + newName + “.” + suffix;
AliyunUtils.getInstance().uploadByte(base64Code.getBytes(), fileKey);
……
…….
return CloudResponseCode.buildEnumResponseVO(CloudResponseCode.FILEUPLOAD_SUCCESS, obj);
}
2. oss utils封装
/**
* 上传byte数组
* @param fileByte
* @param fileKey
*/
public void uploadByte(byte[] fileByte, String fileKey){
// 创建OSSClient实例
OSSClient ossClient = new OSSClient(CloudConstant.ENDPOINT, CloudConstant.ACCESSKEYID, CloudConstant.ACCESSKEYSECRET);
// 上传byte数组
ossClient.putObject(CloudConstant.BUCKET, fileKey, new ByteArrayInputStream(fileByte));
// 关闭client
ossClient.shutdown();
}
/**
* 上传文件流
* @param inputStream
* @param fileKey
*/
public void uploadInputStream(InputStream inputStream, String fileKey){
// 创建OSSClient实例
OSSClient ossClient = new OSSClient(CloudConstant.ENDPOINT, CloudConstant.ACCESSKEYID, CloudConstant.ACCESSKEYSECRET);
// 上传文件流
ossClient.putObject(CloudConstant.BUCKET, fileKey, inputStream);
// 关闭client
ossClient.shutdown();
}
/**
* 删除文件
* @param fileKey
*/
public void deleteFile(String fileKey){
// 创建OSSClient实例
OSSClient ossClient = new OSSClient(CloudConstant.ENDPOINT, CloudConstant.ACCESSKEYID, CloudConstant.ACCESSKEYSECRET);
// 删除文件
ossClient.deleteObject(CloudConstant.BUCKET, fileKey);
// 关闭client
ossClient.shutdown();
}
