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();

}
