删除多版本对象
开发过程中,您有任何问题可以在github上提交issue,或者在华为云对象存储服务论坛中发帖求助。
删除单个多版本对象
您可以通过delete_object接口传入版本号(version_id)删除多版本对象,示例代码如下:
static void test_delete_object_version() { obs_status ret_status = OBS_STATUS_BUTT; // 创建并初始化对象信息 obs_object_info object_info; memset(&object_info, 0, sizeof(obs_object_info)); object_info.key = key; object_info.version_id = version_id; // 创建并初始化option obs_options option; init_obs_options(&option); option.bucket_options.host_name = "<your-endpoint>"; option.bucket_options.bucket_name = "<Your bucketname>"; // 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险,建议在配置文件或者环境变量中密文存放,使用时解密,确保安全;本示例以ak和sk保存在环境变量中为例,运行本示例前请先在本地环境中设置环境变量ACCESS_KEY_ID和SECRET_ACCESS_KEY。 // 您可以登录访问管理控制台获取访问密钥AK/SK,获取方式请参见https://support.huaweicloud.com/usermanual-ca/ca_01_0003.html option.bucket_options.access_key = getenv("ACCESS_KEY_ID"); option.bucket_options.secret_access_key = getenv("SECRET_ACCESS_KEY"); // 设置响应回调函数 obs_response_handler resqonseHandler = { &response_properties_callback, &response_complete_callback }; // 删除对象 delete_object(&option,&object_info,&resqonseHandler, &ret_status); if (OBS_STATUS_OK == ret_status) { printf("delete object successfully. \n"); } else { printf("delete object failed(%s).\n", obs_get_status_name(ret_status)); } }
批量删除多版本对象
您可以通过batch_delete_objects接口传入每个待删除对象的版本号(version_id)批量删除多版本对象,示例代码如下:
static void test_batch_delete_object_version() { obs_status ret_status = OBS_STATUS_BUTT; // 创建并初始化option obs_options option; init_obs_options(&option); option.bucket_options.host_name = "<your-endpoint>"; option.bucket_options.bucket_name = "<Your bucketname>"; // 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险,建议在配置文件或者环境变量中密文存放,使用时解密,确保安全;本示例以ak和sk保存在环境变量中为例,运行本示例前请先在本地环境中设置环境变量ACCESS_KEY_ID和SECRET_ACCESS_KEY。 // 您可以登录访问管理控制台获取访问密钥AK/SK,获取方式请参见https://support.huaweicloud.com/usermanual-ca/ca_01_0003.html option.bucket_options.access_key = getenv("ACCESS_KEY_ID"); option.bucket_options.secret_access_key = getenv("SECRET_ACCESS_KEY"); // 初始化待删对象信息 obs_object_info objectinfo[100]; objectinfo[0].key = "obj1"; objectinfo[0].version_id = "versionid1"; objectinfo[1].key = "obj2"; objectinfo[1].version_id = "versionid2"; obs_delete_object_info delobj; memset_s(&delobj,sizeof(obs_delete_object_info),0,sizeof(obs_delete_object_info)); delobj.keys_number = 2; // 设置响应回调函数 obs_delete_object_handler handler = { {&response_properties_callback, &response_complete_callback}, &delete_objects_data_callback }; // 批量删除对象 batch_delete_objects(&option, objectinfo, &delobj, 0, &handler, &ret_status); if (OBS_STATUS_OK == ret_status) { printf("test batch_delete_objects successfully. \n"); } else { printf("test batch_delete_objects faied(%s).\n", obs_get_status_name(ret_status)); } }
