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.

Tcl

load ./chilkat.dll

set success 0

# 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"

set http [new_CkHttp]

# If SharePoint Windows classic authentication is used, then set the 
# Login, Password, LoginDomain, and NtlmAuth properties.
CkHttp_put_Login $http "SHAREPOINT_USERNAME"
CkHttp_put_Password $http "SHAREPOINT_PASSWORD"
CkHttp_put_LoginDomain $http "SHAREPOINT_NTLM_DOMAIN"
CkHttp_put_NtlmAuth $http 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.
# --------------------------------------------------------------------------------

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

set success [CkHttp_Download $http $url $localFilePath]
if {$success != 1} then {
    puts [CkHttp_lastErrorText $http]
    delete_CkHttp $http
    exit
}

puts "File successfully downloaded from a SharePoint site within a site collection."

delete_CkHttp $http
