啟用FBA調用SharePoint 2013 REST API

Question

我有以下代碼，可以在關閉基於表單的身份驗證的情況下很好地工作，但是一旦我打開它，它就會停止工作：

        string baseURL = siteUrl + "/_api/";
        string uriString = "web/lists/GetByTitle('" + listName + "')/fields/getbyinternalnameortitle('" + displayName + "')";

        NetworkCredential cred = CredentialCache.DefaultNetworkCredentials;
        System.Net.Http.HttpClient client = new System.Net.Http.HttpClient(new HttpClientHandler()
        {
            Credentials = cred
        });

        client.BaseAddress = new Uri(baseURL);
        client.DefaultRequestHeaders.Add("Accept", "application/json;odata=verbose");

        ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain,
                SslPolicyErrors sslPolicyErrors)
        {
            return true;
        };

        HttpResponseMessage resp = client.GetAsync(uriString).Result;
        string respString = resp.Content.ReadAsStringAsync().Result;

我得到的響應如下：

{StatusCode: 403, ReasonPhrase: 'Forbidden', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
Transfer-Encoding: chunked
X-SharePointHealthScore: 0 
X-Forms_Based_Auth_Required:...)

我嘗試了幾件事，包括在HttpClient Credentials對象上指定服務器場帳戶Windows身份驗證憑據，還嘗試了使用AuthenticationHeaderValue：

 client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", _FormatBasicAuth("domain", "username", "password"));

任何幫助將不勝感激。

對於遇到此問題的任何人，我都可以通過轉至“網站權限”並設置對整個網站的匿名訪問來解決。
