Object Storage Service:Set object tags (Swift SDK)

You can use the following code to add tags to an object.

import AlibabaCloudOSS
import Foundation

@main
struct Main {
    static func main() async {
        do {
            // Specify the region where the bucket is located. Example: China (Hangzhou) is cn-hangzhou.
            let region = "cn-hangzhou" // Replace with your actual region ID.
            // Specify the bucket name.
            let bucket = "yourBucketName" // Replace with your actual bucket name.
            // Optional. Specify the domain name to access OSS. For example, for the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com.
            let endpoint: String? = nil
            // Specify the name of the object for which to set tags, such as document.txt.
            let key = "yourObjectName" // Replace with your actual object name.

            // Obtain access credentials from environment variables. Before you run this sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are set.
            let credentialsProvider = EnvironmentCredentialsProvider()

            // Configure OSS client parameters.
            let config = Configuration.default()
                .withRegion(region)        // Set the region where the bucket is located.
                .withCredentialsProvider(credentialsProvider)  // Set the access credentials.
                
            // Set a custom endpoint.
            if let endpoint = endpoint {
                config.withEndpoint(endpoint)
            }

            // Create an OSS client instance.
            let client = Client(config)
            
            var tags: [Tag] = []
            tags.append(Tag(key: "key1",value: "value1")) // Replace with an actual tag key-value pair.
            tags.append(Tag(key: "key2",value: "value2")) // Replace with an actual tag key-value pair.

            // Set object tags.
            let result = try await client.putObjectTagging(
                PutObjectTaggingRequest(
                    bucket: bucket,
                    key: key,
                    tagging: Tagging(tagSet: TagSet(tags: tags))
                )
            )
            print("result:\n\(result)") // Print the result.

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