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. Visual FoxPro

LOCAL lnSuccess
LOCAL loHttp
LOCAL lcBucketName
LOCAL lcObjectName
LOCAL lcLocalFilePath
LOCAL lcContentType

lnSuccess = 0

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

loHttp = CreateObject('Chilkat.Http')

* 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")

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

IF (lnSuccess <> 1) THEN
    ? loHttp.LastErrorText
ELSE
    ? "File uploaded."
