(VB.NET UWP/WinRT) 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.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

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

Dim http As New Chilkat.Http

' If SharePoint Windows classic authentication is used, then set the 
' Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME"
http.Password = "SHAREPOINT_PASSWORD"
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN"
http.NtlmAuth = True

' 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.
http.SetRequestHeader("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.
Dim sAllFields As String = Await http.QuickGetStrAsync("https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFolderByServerRelativeUrl('/Documents/ChilkatTest')/ListItemAllFields")
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


Dim json As New Chilkat.JsonObject
json.Load(sAllFields)
json.EmitCompact = False

Debug.WriteLine(json.Emit())

' 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)"

' 
' { 
'   "d": {

'       "etag": "\"4\"",
'       "type": "SP.Data.DocumentsItem"
'     },
'     ...
'     ...
'     "FileSystemObjectType": 1,
'     "Id": 62,
'     "ContentTypeId": "0x012000FA905915D7D8F7458C1A0AF1E981BFF5",

' Step 2...

' To rename a folder, we're going to POST to
' https://SHAREPOINT_HTTPS_DOMAIN/_api/Web/Lists(guid'b0d92cec-4be1-4e52-943d-ebcb432e1c3b')/Items(62)
' with a request body containing the following JSON:
' 
'     { "__metadata": { "type": "THE_TYPE_FROM_ABOVE" }, "Title": "New title", "FileLeafRef": "New title"}
' 

' Build the Path, which is "/_api/" + the id from above.
Dim sbPath As New Chilkat.StringBuilder
sbPath.Append("/_api/")
sbPath.Append(json.StringOf("d.__metadata.id"))

Dim req As New Chilkat.HttpRequest
req.HttpVerb = "POST"
req.Path = sbPath.GetAsString()

' We need to add a form digest value in the X-RequestDigest header field.
' See this example for details on
' how to get (and cache) a form digest value
req.AddHeader("X-RequestDigest","SHAREPOINT_FORM_DIGEST")

' Set the Content-Type, and indicate that a JSON response is desired.
req.ContentType = "application/json;odata=verbose"
req.AddHeader("Accept","application/json;odata=verbose")

' We need a few more headers...
req.AddHeader("IF-MATCH",json.StringOf("d.__metadata.etag"))
req.AddHeader("X-HTTP-Method","MERGE")

' Create and add the JSON body.
Dim jsonBody As New Chilkat.JsonObject
jsonBody.UpdateString("__metadata.type",json.StringOf("d.__metadata.type"))
jsonBody.UpdateString("Title","ChilkatTest2")
jsonBody.UpdateString("FileLeafRef","ChilkatTest2")
req.LoadBodyFromString(jsonBody.Emit(),"utf-8")

' Send the POST using HTTPS.
Dim bUseTls As Boolean = True
Dim resp As Chilkat.HttpResponse = Await http.SynchronousRequestAsync("SHAREPOINT_HTTPS_DOMAIN",443,bUseTls,req)
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


' The response body contains JSON.
' When successful, it will be empty.
json.Load(resp.BodyStr)
json.EmitCompact = False

Debug.WriteLine("Response status code = " & resp.StatusCode)

' The expected success response code is 204.
If (resp.StatusCode <> 204) Then
    Debug.WriteLine("Response status code = " & resp.StatusCode)
    Debug.WriteLine(json.Emit())
    Debug.WriteLine("Failed")

    Exit Sub
End If




' The response body is empty for a 204 (success) response...
Debug.WriteLine("Success.")
