Object Storage Service:Delete files (Swift SDK)

deleteObject sends an asynchronous request to permanently delete one object from a bucket. The operation succeeds if no exception is thrown.

        do {
            // The region where the bucket is located. Example: cn-hangzhou for China (Hangzhou).
            let region = "cn-hangzhou"
            // The bucket name.
            let bucket = "yourBucketName"
            // Optional. The domain name to access OSS. For China (Hangzhou), set the endpoint to https://oss-cn-hangzhou.aliyuncs.com.
            let endpoint: String? = nil
            // The name of the object to delete, such as test.txt.
            let key = "yourObjectName"

            // Initialize the credential provider to load credentials from environment variables.
            let credentialsProvider = EnvironmentCredentialsProvider()

            // Configure the OSS client.
            let config = Configuration.default()
                .withRegion(region)
                .withCredentialsProvider(credentialsProvider)

            // Set the endpoint.
            if let endpoint = endpoint {
                config.withEndpoint(endpoint)
            }

            // Create an OSS client instance.
            let client = Client(config)

            // Send a request to delete the object.
            let result = try await client.deleteObject(
                DeleteObjectRequest(
                    bucket: bucket,
                    key: key
                )
            )
            print("result:\n\(result)")

        } catch {
            // Print the error message and continue.
            print("error: \(error)")
        }
    }
}

deleteMultipleObjects deletes a batch of objects in a single request. Build a [DeleteObject] array from the object keys, then pass it to DeleteMultipleObjectsRequest.
