(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"
# If your Sharepoint site is within a site collection, then use "https://SHAREPOINT_HTTPS_DOMAIN/sites/teamA/_api/web/GetFolderByServerRelativeUrl('/sites/teamA/Documents/ChilkatTest')/ListItemAllFields" where "teamA" is the name of the site.
set sAllFields [CkHttp_quickGetStr $http "https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFolderByServerRelativeUrl('/Documents/ChilkatTest')/ListItemAllFields"]
if {[CkHttp_get_LastMethodSuccess $http] != 1} then {
    puts [CkHttp_lastErrorText $http]
    delete_CkHttp $http
    exit
}

puts [CkJsonObject_emit $json]

# The JSON response will look like this:
# We'll need to get the "id", "etag", and "type" for the next step.  The "id" for the
# sample below is "Web/Lists(guid'b0d92cec-4be1-4e52-943d-ebcb432e1c3b')/Items(62)"
