I am authenticating with cookie to online Sharepoint, as answered here:

REST - Authentication to online Sharepoint

When I try to authenticate I get 401 error.

This is my code:

   List<String> fileList = new ArrayList<>();
try {
    //here I get cookie value
    CookieStore cookieStore = getCookieStore(.....);
    HttpClient httpClient = HttpClientBuilder.create().setDefaultCookieStore(cookieStore).build();
    String uri = URL  + "/" + "_api/web/GetFolderByServerRelativeUrl(\'" + FOLDER_NAME + "\')/files";        
    HttpGet httpGet = new HttpGet(uri);
    httpGet.addHeader("Accept", "application/json;odata=verbose");
    httpGet.addHeader("X-FORMS_BASED_AUTH_ACCEPTED", "f");

    // Make the request.
    HttpResponse response = httpClient.execute(httpGet);
    // Process the result
    int statusCode = response.getStatusLine().getStatusCode();
    if (statusCode == 200) {
} catch (Exception e) {
    log.error("", e);

My cookie store is something like this: [[version: 0][name: SPOIDCRL][value: 77u/PD94bWwgdmVyc2lvbj.......

But, I am geting 401 with error: HTTP/1.1 401 Unauthorized

Again I can't authorise to SP. Can you help me one more time?



I have not tried the Java client. But I can successfully issue the same request with the HttpClient class in the .NET framework. Make sure the cookie has the format:


Also, you do not need to include the X-FORMS_BASED_AUTH_ACCEPTED header.
