1.首先要去华为云[https://console.huaweicloud.com/][https_console.huaweicloud.com]注册一下，申请密钥

2.然后去左边导航栏找到OBS

3.然后按照流程导图创建存储桶

拿到这几个参数就可以了

搞一个配置文件，把参数都填上

然后创建一个obs的工具类

private static final String PROP_FILE_NAME = "huaweicloud-obs-config.properties";
    
        private static PropertiesUtil propertiesUtil = new PropertiesUtil(PROP_FILE_NAME);
    
        private static final String AK = propertiesUtil.getStringProperty("huawei.obs.secret.ak");
    
        private static final String SK = propertiesUtil.getStringProperty("huawei.obs.secret.sk");
    
        private static final String ENDPOINT = propertiesUtil.getStringProperty("huawei.obs.upload.endPoint");
    
        private static final String BUCKET_NAME = propertiesUtil.getStringProperty("huawei.obs.upload.bucketName");
    
        private static final String PARENT_DIR = propertiesUtil.getStringProperty("huawei.obs.upload.parentDir");
    
        /**
         * OBS-上传文件
         *
         * @param objectKey   具体的文件名（含存储路径）
         * @param inputStream 输入流
         * @return PutObjectResult
         */
        public static PutObjectResult uploadFile(String objectKey, InputStream inputStream) {
    
            ObsClient obsClient = null;
            PutObjectResult putObjectResult = null;
    
            try {
    
                obsClient = new ObsClient(AK, SK, ENDPOINT);
                putObjectResult = obsClient.putObject(BUCKET_NAME, PARENT_DIR + objectKey, inputStream);
                log.info("上传文件PutObjectResult============" + putObjectResult);
    
            } catch (ObsException e) {
                printObsException(objectKey, e, "RpcInterTypeCodeListModel.HUAWEIUPLOADFILE");
            } catch (Exception e) {
                e.printStackTrace();
                log.error("OBS上传文件报错Exception===============" + e.getMessage());
            } finally {
    
                if (obsClient != null) {
                    try {
                        // 关闭OBS连接
                        obsClient.close();
                    } catch (IOException e) {
                        log.error("OBS关闭连接报错！===============" + e.getMessage());
                    }
                }
    
            }
            return putObjectResult;
        }
