(PowerBuilder) SharePoint -- Download File (Site Collection)

Demonstrates how to download a file from SharePoint located in the /Documents folder in a site within a site collection.

The format for a URL for a resource contained in a site within a site collection is like this:

https://contoso.com/sites/teamA/_api/web/GetFolderByServerRelativeUrl('/sites/teamA/Documents')/Files('SomeDocument.docx')/$value

Notice that the "/sites/teamA" (where "teamA" is the name of the site) occurs twice in the URL.

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

// -------------------------------------------------------------------------
// The following comments apply to SharePoint Windows classic authentication.
// -------------------------------------------------------------------------
// For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
// The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
// The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
// Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
// for example, "chilkat" instead of "chilkat@mycompany.com"

loo_Http = create oleobject
// Use "Chilkat_9_5_0.Http" for versions of Chilkat < 10.0.0
li_rc = loo_Http.ConnectToNewObject("Chilkat.Http")
if li_rc < 0 then
    destroy loo_Http
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// If SharePoint Windows classic authentication is used, then set the 
// Login, Password, LoginDomain, and NtlmAuth properties.
loo_Http.Login = "SHAREPOINT_USERNAME"
loo_Http.Password = "SHAREPOINT_PASSWORD"
loo_Http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN"
loo_Http.NtlmAuth = 1

// -------------------------------------------------------------------------
// The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
// If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
// establish the cookie as shown at SharePoint Online Authentication
// -------------------------------------------------------------------------

// This example downloads the file named "Domain Name created for Exchange.docx"

// Note: I was initially confused by the "$value" part of the URL. 
// When I see something like $value, I immediately think that it's some sort of
// variable or placeholder to be replaced with an actual value.  In this case,
// the "$value" is literally part of the URL.  It's not replace with anything.

// --------------------------------------------------------------------------------
// IMPORTANT: The format for a URL within a site collection is like this:
// https://SHAREPOINT_HTTPS_DOMAIN/sites/teamA/_api/web/GetFolderByServerRelativeUrl('/sites/teamA/Documents')/Files('Domain Name created for Exchange.docx')/$value
// 
// Notice that "/sites/teamA" is specified twice in the above sample URL.
// --------------------------------------------------------------------------------

ls_Url = "https://SHAREPOINT_HTTPS_DOMAIN/sites/teamA/_api/web/GetFolderByServerRelativeUrl('/sites/teamA/Documents')/Files('Domain Name created for Exchange.docx')/$value"
ls_LocalFilePath = "qa_output/x.docx"

li_Success = loo_Http.Download(ls_Url,ls_LocalFilePath)
if li_Success <> 1 then
    Write-Debug loo_Http.LastErrorText
    destroy loo_Http
    return
end if

Write-Debug "File successfully downloaded from a SharePoint site within a site collection."
