Creating a Folder

If you have any questions during development, post them on the Issues page of GitHub.

There is no folder concept in OBS. All elements in buckets are objects. To create a folder in OBS is essentially to create an object whose size is 0 and whose name ends with a slash (/). Such objects have no difference from other objects and can be downloaded and deleted, except that they are displayed as folders in OBS Console. 
static void test_creat_folder()
{    
    char *key = "YourFolder/";    
    // Initialize option.
    obs_options option;    
    init_obs_options(&option);    
    option.bucket_options.host_name = "<your-endpoint>";    
    option.bucket_options.bucket_name = "<Your bucketname>";  

    // Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY.
    // Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/en-us/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");
 
    option.bucket_options.uri_style = OBS_URI_STYLE_PATH;    
    temp_auth_configure tempauth;    
    tempAuthResult  ptrResult;    
    memset(&ptrResult,0,sizeof(tempAuthResult));    
    // Initialize the properties of an object to be uploaded.
    obs_put_properties put_properties;    
    init_put_properties(&put_properties);    
    // Initialize the structure for storing uploaded data.
    put_file_object_callback_data data;    
    memset(&data, 0, sizeof(put_file_object_callback_data));    
    // Set callback function.
    obs_put_object_handler putobjectHandler =    
    {         
        { &response_properties_callback, &put_file_complete_callback },        
        &put_file_data_callback    
    };    
    
    put_object(&option, key, 0, &put_properties, 0, &putobjectHandler, &data);    
    if (OBS_STATUS_OK == data.ret_status) 
    {        
        printf("put object from file successfully. \n");    
    }    
    else    
    {        
        printf("put object failed(%s).\n",                 
            obs_get_status_name(data.ret_status));    
    }
}
  • To create a folder in OBS is to create an object whose size is 0 and whose name ends with a slash (/), in essential.
  • To create a multi-level folder, you only need to create the folder with the last level. For example, if you want to create a folder named src1/src2/src3/, create it directly, no matter whether the src1/ and src1/src2/ folders exist.
