Question

我收到错误消息＆＃34; 403 Forbidden＆＃34;从我的C＃项目调用GetListCollection方法。在线2013和URL中的sharepoint版本以HTTPS开头。

我的HTTP标头请求的代码是：

string _url = "https://my.sharepoint.com/"+ "_vti_bin/Lists.asmx";

string soapStr =
            @"<?xml version=""1.0"" encoding=""utf-8""?>
                <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"">
                    <soap:Body>
                        <GetListCollection xmlns=""http://schemas.microsoft.com/sharepoint/soap/"" />
                    </soap:Body>
                </soap:Envelope>";

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(_url);

req.Headers.Add("SOAPAction", "\"http://schemas.microsoft.com/sharepoint/soap/GetListCollection\"");
req.ContentType = "text/xml; encoding='utf-8'";
req.Credentials = new NetworkCredential(userName, userPassword);
req.Method = "POST";

            using (Stream stm = req.GetRequestStream())
            {
                soapStr = string.Format(soapStr);
                using (StreamWriter stmw = new StreamWriter(stm))
                {
                    stmw.Write(soapStr);
                }
            }
            StreamReader responseReader = new StreamReader(req.GetResponse().GetResponseStream());

有人可以告诉我我错在哪里或者我需要做什么吗？

403 FORBIDDEN

Answer 1

发生此错误，因为NetworkCredential class可能在Office 365中使用，Microsoft支持claims-based authentication in Office 365。

SharePoint Online Client Components SDK已发布，其中包含
SharePointOnlineCredentials class访问SharePoint Online资源。

如何在Office 365中使用SharePoint Web服务

以下示例演示了如何在Office 365中验证请求：

string endpointUrl = webUri + "/_vti_bin/Lists.asmx";
var envelope = 
                  "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                  "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">" +
                    "<soap:Body>" +
                       "<GetListCollection xmlns=\"http://schemas.microsoft.com/sharepoint/soap/\" />" +
                    "</soap:Body>" +
                  "</soap:Envelope>";


var request = (HttpWebRequest) WebRequest.Create(endpointUrl);
request.ContentType = "text/xml; encoding='utf-8'";
request.Credentials = GetCredentials(userName, password);
request.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f");
request.Method = "POST";
using (var requestStream = request.GetRequestStream())
{
    using (var streamWriter = new StreamWriter(requestStream))
    {
       streamWriter.Write(envelope);
    }
}


using (var response = request.GetResponse())
{
     using (var responseStream = response.GetResponseStream())
     {
        var streamReader = new StreamReader(responseStream);
        var data = streamReader.ReadToEnd();
     }         
}

，其中

 public static SharePointOnlineCredentials GetCredentials(string userName, string password)
 {
     var securePassword = new SecureString();
     foreach (var ch in password) securePassword.AppendChar(ch);
     return  new SharePointOnlineCredentials(userName, securePassword);
 }

Answer 2

403 Forbidden是尝试通过HTTPS访问服务而未在客户端正确设置证书时接收的典型错误代码。话虽如此，问题可能出在多个地方，也取决于您尝试联系的服务器上如何设置身份验证。

我认为this article将有助于启动。然后看this thread，因为讨论指出了可能对您有所帮助的几个问题和想法。

用于HTTPS的HttpWebRequest获得403 Forbidden Error
