(Swift) S3 Download Specific Version of File
Demonstrates how to download a file from the Amazon S3 service using the versionId query parameter.
Note: This example requires Chilkat v9.5.0.89 or later. (A problem regarding AwsSubResources w/ downloads was fixed shortly after the v9.5.0.88 release.)
func chilkatTest() {
// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
let http = CkoHttp()!
http.awsAccessKey = "AWS_ACCESS_KEY"
http.awsSecretKey = "AWS_SECRET_KEY"
http.awsRegion = "us-east-1"
http.awsEndpoint = "s3.amazonaws.com"
http.awsSubResources = "versionId=x8UPzRsgskmbe55lEQvhLi25PQl2lcFH"
var bucketName: String? = "chilkat100"
var objectName: String? = "frenchUtf8.txt"
var localFilePath: String? = "qa_output/frenchUtf8.txt"
var success: Bool = http.s3_DownloadFile(bucketName, objectName: objectName, localFilePath: localFilePath)
if success != true {
print("\(http.lastErrorText!)")
}
else {
print("File downloaded.")
}
}
