以下 WithDefaultCredentials() 有效,但 WithCredentialsMe() 失败并返回 http 401?不同之处在于 ICredentials 凭据 = System.Net.CredentialCache.DefaultCredentials; 对报表服务器 2008 url 工作正常,但 ICredentials credentials = new NetworkCredential("myUsername", "myPassword", "ourDomain"); 返回一个 HTTP 401。
我正在开发控制台应用程序,因此 DefaultCredentials 和 NetworkCredential 之间应该没有区别。我的用户名和密码没有问题。
有任何想法吗 ?
