A bucket is a container used to store objects in Object Storage Service (OSS). Each object is contained in a bucket. This topic describes how to create a bucket.

Examples

The following code provides an example on how to create a bucket:

#include "oss_api.h"
#include "aos_http_io.h"
/* Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. */
const char *endpoint = "yourEndpoint";
/* The AccessKey pair of an Alibaba Cloud account has permissions on all API operations. Using these credentials to perform operations in OSS is a high-risk operation. We recommend that you use a RAM user to call API operations or perform routine O&M. To create a RAM user, log on to the RAM console. */
const char *access_key_id = "yourAccessKeyId";
const char *access_key_secret = "yourAccessKeySecret";
/* Specify the bucket name. Example: examplebucket. */
const char *bucket_name = "examplebucket";
void init_options(oss_request_options_t *options)
{
    options->config = oss_config_create(options->pool);
    /* Use a char* string to initialize the aos_string_t data type. */
    aos_str_set(&options->config->endpoint, endpoint);
    aos_str_set(&options->config->access_key_id, access_key_id);
    aos_str_set(&options->config->access_key_secret, access_key_secret);
    /* Specify whether to use CNAME to access OSS. A value of 0 indicates that CNAME is not used.  */
    options->config->is_cname = 0;
    /* Configure network parameters such as the timeout period. */
    options->ctl = aos_http_controller_create(options->pool, 0);
}
int main(int argc, char *argv[])
{
    /* Call the aos_http_io_initialize method in main() to initialize global resources such as networks and memory.  */
    if (aos_http_io_initialize(NULL, 0) != AOSE_OK) {
        exit(1);
    }
    /* Create a memory pool to manage memory. aos_pool_t is equivalent to apr_pool_t. The code used to create a memory pool is included in the APR library. */
    aos_pool_t *pool;
    /* Create a memory pool. The value of the second parameter is NULL. This value indicates that the pool does not inherit other memory pools. */
    aos_pool_create(&pool, NULL);
    /* Create and initialize options. This parameter specifies global configuration information such as endpoint, access_key_id, access_key_secret, is_cname, and curl. */
    oss_request_options_t *oss_client_options;
    /* Allocate the memory resources in the memory pool to the options. */
    oss_client_options = oss_request_options_create(pool);
    /* Initialize oss_client_options. */
    init_options(oss_client_options);
    /* Initialize the parameters. */
    aos_string_t bucket;
    oss_acl_e oss_acl = OSS_ACL_PRIVATE;
    aos_table_t *resp_headers = NULL; 
    aos_status_t *resp_status = NULL; 
    /* Assign char* data to a bucket of the aos_string_t type.  */
    aos_str_set(&bucket, bucket_name);
    /* Create the bucket. */
    resp_status = oss_create_bucket(oss_client_options, &bucket, oss_acl, &resp_headers);
    /* Determine whether the bucket is created.  */
    if (aos_status_is_ok(resp_status)) {
        printf("create bucket succeeded\n");
    } else {
        printf("create bucket failed\n");
    }
    /* Release the memory pool. This operation releases the memory resources allocated for the request. */
    aos_pool_destroy(pool);
    /* Release the allocated global resources.  */
    aos_http_io_deinitialize();
    return 0;
}

The following code provides an example on how to set the access control list (ACL) of a bucket when you create the bucket:

    /* Create a bucket and set the ACL of the bucket to public read. The default ACL is private. */
    resp_status = oss_create_bucket(oss_client_options, &bucket, OSS_ACL_PUBLIC_READ, &resp_headers);
    if (aos_status_is_ok(resp_status)) {
        printf("create bucket succeeded\n");
    } else {
        printf("create bucket failed\n");
    }

The following code provides an example on how to create an Infrequent Access (IA) bucket:

To create an Archive bucket, replace OSS_STORAGE_CLASS_IA in the following example with OSS_STORAGE_CLASS_ARCHIVE.

    resp_status = oss_create_bucket_with_storage_class(oss_client_options, &bucket, OSS_ACL_PRIVATE, OSS_STORAGE_CLASS_IA);
    /* Determine whether the bucket is created.  */
    if (aos_status_is_ok(resp_status)) {
        printf("create bucket succeeded\n");
    } else {
        printf("create bucket failed\n");
    }
