主题：关于第三方接口调用

请问下，我用试用版做了这个接口，使用正常的，到了正式开发版里面，就提示远程服务器返回错误: (401) 未经授权，这2个版本还有什么不同的吗？下面是语句

蓝老师，请问下，我用上面的方式调用接口成功了，用下面这个 HttpClient调用就提示未经授权，能帮忙看下是什么问题吗      

'定义接口
        Dim web As New HttpClient("http://www.xxx.com")
        web.Headers.Add("Content-Type", "application/json")
        web.Headers.Add("Content-Length", " ")
        web.Headers.Add("x-ca-key", akey)
        web.Headers.Add("x-ca-signature", Hmac)
        '输入
        web.Content = xmlRequest
        '输出
        Dim CC1101 As String = web.GetData
