(JavaScript) 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.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var http = new CkHttp();

// 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.
var sAllFields = http.QuickGetStr("https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFolderByServerRelativeUrl('/Documents/ChilkatTest')/ListItemAllFields");
if (http.LastMethodSuccess == false) {
    console.log(http.LastErrorText);
    return;
}

var json = new CkJsonObject();
json.Load(sAllFields);
json.EmitCompact = false;

console.log(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": { 
//       "id": "Web/Lists(guid'b0d92cec-4be1-4e52-943d-ebcb432e1c3b')/Items(62)",
//       "uri": "https://SHAREPOINT_HTTPS_DOMAIN/_api/Web/Lists(guid'b0d92cec-4be1-4e52-943d-ebcb432e1c3b')/Items(62)",
//       "etag": "\"4\"",
//       "type": "SP.Data.DocumentsItem"
//     },
//     ...
//     ...
//     "FileSystemObjectType": 1,
//     "Id": 62,
//     "ContentTypeId": "0x012000FA905915D7D8F7458C1A0AF1E981BFF5",
//     "Title": "ChilkatTest",
//     "OData__dlc_DocId": null,
//     "OData__dlc_DocIdUrl": null,
//     "URL": null,
//     "DocumentSetDescription": null,
//     "EditorId": 25,
//     "ID": 62,
//     "Created": "2017-04-12T19:18:29",
//     "AuthorId": 25,
//     "Modified": "2017-04-12T19:49:15",
//     "OData__CopySource": null,
//     "CheckoutUserId": null,
//     "OData__UIVersionString": "1.0",
//     "GUID": "71f30f44-e33a-48e7-b4d8-9d619ba1ad69"
//   }
// }

// -------------------------------------------------------------------------------
// 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.
var sbPath = new CkStringBuilder();
sbPath.Append("/_api/");
sbPath.Append(json.StringOf("d.__metadata.id"));

var req = new CkHttpRequest();
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.
var jsonBody = new CkJsonObject();
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.
var bUseTls = true;
var resp = new CkHttpResponse();
success = http.HttpSReq("SHAREPOINT_HTTPS_DOMAIN",443,bUseTls,req,resp);
if (success == false) {
    console.log(http.LastErrorText);
    return;
}

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

console.log("Response status code = " + resp.StatusCode);

// The expected success response code is 204.
if (resp.StatusCode !== 204) {
    console.log("Response status code = " + resp.StatusCode);
    console.log(json.Emit());
    console.log("Failed");
    return;
}

// The response body is empty for a 204 (success) response...
console.log("Success.");
