(Unicode C++) 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.

    CkHttpW http;

    // If SharePoint Windows classic authentication is used, then set the 
    // Login, Password, LoginDomain, and NtlmAuth properties.
    http.put_Login(L"SHAREPOINT_USERNAME");
    http.put_Password(L"SHAREPOINT_PASSWORD");
    http.put_LoginDomain(L"SHAREPOINT_NTLM_DOMAIN");
    http.put_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(L"Accept",L"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.
    const wchar_t *sAllFields = http.quickGetStr(L"https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFolderByServerRelativeUrl('/Documents/ChilkatTest')/ListItemAllFields");
    if (http.get_LastMethodSuccess() != true) {
        wprintf(L"%s\n",http.lastErrorText());
        return;
    }

    CkJsonObjectW json;
    json.Load(sAllFields);
    json.put_EmitCompact(false);

    wprintf(L"%s\n",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": { 
    //     "__metadata": {

    //     },

    // Step 2...

    // To rename a folder, we're going to POST to

    // 

    // Build the Path, which is "/_api/" + the id from above.
    CkStringBuilderW sbPath;
    sbPath.Append(L"/_api/");
    sbPath.Append(json.stringOf(L"d.__metadata.id"));

    CkHttpRequestW req;
    req.put_HttpVerb(L"POST");
    req.put_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(L"X-RequestDigest",L"SHAREPOINT_FORM_DIGEST");

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

    // We need a few more headers...
    req.AddHeader(L"IF-MATCH",json.stringOf(L"d.__metadata.etag"));
