Upload File with User-Defined Metadata

See more Amazon S3 Examples

Demonstrates how to upload a file with user-defined metadata to the Amazon S3 service. Lianja

llSuccess = .F.

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

loHttp = createobject("CkHttp")

// Insert your AWS keys here:
loHttp.AwsAccessKey = "AWS_ACCESS_KEY"
loHttp.AwsSecretKey = "AWS_SECRET_KEY"

lcBucketName = "chilkat.ocean"
lcObjectName = "seahorse.jpg"
lcLocalFilePath = "qa_data/jpg/seahorse.jpg"
lcContentType = "image/jpg"

// User-defined metadata are name/value pairs, and are added to the HTTP request header.
// Header names must begin with "x-amz-meta-" to distinguish them from other HTTP headers.
// Note that Amazon S3 stores user-defined metadata keys in lowercase.

// For example, to add genus=Hippocampus, we do this:
loHttp.SetRequestHeader("x-amz-meta-genus","Hippocampus")

// Add a few more user-metadata key pairs.
loHttp.SetRequestHeader("x-amz-meta-species","big-belly seahorse")
loHttp.SetRequestHeader("x-amz-meta-habitat","shallow tropical and temperate waters")

llSuccess = loHttp.S3_UploadFile(lcLocalFilePath,lcContentType,lcBucketName,lcObjectName)

if (llSuccess <> .T.) then
    ? loHttp.LastErrorText
else
    ? "File uploaded."
