(Tcl) SharePoint -- Rename Folder

This example shows how to rename SharePoint folder.

Renaming a folder is not straightforward. Apparently, the information published by Microsoft is incorrect and simply doesn't work (the information about how to update a folder by using the MERGE method is incorrect).

To rename a folder requires two steps, as demonstrated by this example.

load ./chilkat.dll

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

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

#  The first step in renaming a file is send a GET to the /ListItemAllFields endpoint:
#  Indicate we want a JSON response.
CkHttp_SetRequestHeader $http "Accept" "application/json;odata=verbose"

#  In this example, we want to rename the folder "/Documents/ChilkatTest" to "/Documents/ChilkatTest2"
