我在通过 REST 在 CRM Dynamics 中进行身份验证时遇到问题。此问题仅在我尝试连接时发生从带有 CentOS 的机器（在 Ubuntu 和 Windows 中工作）。

有人知道这些警告（“找不到任何帮助程序支持 HTTP_Negotiate 质询方案。” 和“找不到任何支持 HTTP_NTLM 质询方案的助手。”）？

【解决方案1】：

您应该使用网络连接器并调用：

// Create your own authenticator
Authenticator a = new Authenticator() {
    public PasswordAuthentication getPasswordAuthentication() {
        return (new PasswordAuthentication("<your account>", "<your password>".toCharArray()));
    }
};

// Sets the default Authenticator
Authenticator.setDefault(a);
