错误：远程服务器返回错误：（401）未授权

Question

我想获取互联网的图片并插入到单词中。

我使用此代码。

MainDocumentPart mainPart = wordprocessingDocument.MainDocumentPart; 
System.Net.WebRequest request = 
    System.Net.HttpWebRequest.Create("http://spsdev2:1009"); 

System.Net.WebResponse response = request.GetResponse(); 
ImagePart imagePart = mainPart.AddImagePart(ImagePartType.Jpeg); 
//Send an HTTP request and get the image at the URL as an HTTP response 
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(fileName); 
WebResponse myResp = myReq.GetResponse(); 

//Get a stream from the webresponse 
Stream stream = myResp.GetResponseStream(); 

我在myReq.GetResponse（）中得到错误;

错误：远程服务器返回错误：（401）未经授权。

编辑对我来说

此代码工作:)

myReq.UseDefaultCredentials = true; 

myReq.PreAuthenticate = true; 

myReq.Credentials = CredentialCache.DefaultCredentials; 

Answer 1

我添加凭据HttpWebRequest。

myReq.UseDefaultCredentials = true; 
myReq.PreAuthenticate = true; 
myReq.Credentials = CredentialCache.DefaultCredentials; 

Answer 2

你不是应该提供的凭据为您的网站，而不是传递的DefaultCredentials？

喜欢的东西request.Credentials = new NetworkCredential("UserName", "PassWord");

此外，删除request.UseDefaultCredentials = true; request.PreAuthenticate = true;
