Setting an inventory job

Note

This API is used to create an inventory job for a bucket. For more information, see Inventory Overview.
Note
Up to 1,000 inventory tasks can be configured in one COS bucket.
You must write a bucket policy to the destination bucket for COS to put the result file of the inventory task in it.
When calling this request, make sure that you have sufficient permission to manipulate the bucket's inventory tasks, which is granted to the bucket owner by default. If you do not have it, apply for it to the bucket owner first.

Sample Request

Sample 1. Creating an inventory job with server-side encryption.
cos.putBucketInventory({
    Bucket: 'sourcebucket-1250000000', /* Required */
    Region: 'ap-beijing',               /* Required */
    Id: 'inventory_test',       // Required
    InventoryConfiguration: {
        Id: 'inventory_test',
        IsEnabled: 'true',
        Destination: {
            COSBucketDestination: {
                Format: 'CSV',
                AccountId: '100000000001',
                Bucket: 'qcs::cos:ap-beijing::targetbucket-1250000000',
                Prefix: 'inventory_test_prefix',
                Encryption: {
                    SSECOS: ''
}
}
		},
        Schedule: {
            Frequency: 'Daily'
		},
        Filter: {
            Prefix: 'filter_prefix'
		},
        IncludedObjectVersions: 'All',
        OptionalFields: [
            'Size',
            'LastModifiedDate',
            'StorageClass',
            'ETag'
		]
}
}, function(err, data) {
    console.log(err || data);
});
Sample 2. Creating an inventory job without server-side encryption.
cos.putBucketInventory({
    Bucket: 'sourcebucket-1250000000', /* Required */
    Region: 'ap-beijing',               /* Required */
    Id: 'inventory_test',       // Required
    InventoryConfiguration: {
        Id: 'inventory_test',
        IsEnabled: 'true',
        Destination: {
            COSBucketDestination: {
                Format: 'CSV',
                AccountId: '100000000001',
                Bucket: 'qcs::cos:ap-beijing::targetbucket-1250000000',
                Prefix: 'inventory_test_prefix'
}
		},
        Schedule: {
            Frequency: 'Daily'
		},
        Filter: {
            Prefix: 'filter_prefix'
		},
        IncludedObjectVersions: 'All',
        OptionalFields: [
            'Size',
            'LastModifiedDate',
            'StorageClass',
            'ETag'
		]
}
}, function(err, data) {
    console.log(err || data);
});
