Creating an Inventory Configuration

API description

This API (PUT Bucket inventory) is used to create an inventory configuration for a bucket.

Method prototype

CosResult BucketOp::PutBucketInventory(const PutBucketInventoryReq& req, PutBucketInventoryResp* resp);

Sample request

qcloud_cos::CosConfig config("./config.json");
qcloud_cos::CosAPI cos(config);
std::string bucket_name = "examplebucket-1250000000";
qcloud_cos::PutBucketInventoryReq req(bucket_name);
qcloud_cos::PutBucketInventoryResp resp;

// Create an inventory configuration.
req.SetId("list");

COSBucketDestination destination;
destination.SetFormat("CSV");
destination.SetAccountId("100010974959");

destination.SetBucket("qcs::cos:ap-guangzhou::loggtest-1234567890");

req.SetInventory(inventory);

qcloud_cos::CosResult result = cos.PutBucketInventory(req, &resp);

}

// Information about where to publish the inventory results
class COSBucketDestination {
public:
    void SetFormat(const std::string& format) // Specify the format of the inventory. Currently, CSV is supported.    
    void SetAccountId(const std::string& accountId) // Specify the ID of the bucket owner.
