验证码总是返回false

Question

可能是重复的问题。我有一个SPA和实施的reCAPTCHA这我在本地主机上运行，​​并给我一个错误：“假\ nincorrect - 验证码 - 溶胶”。我使用的代码如下所示为从原始源here。它是用相同的密钥（私有和公有）前的工作。我应该怎么可能改变或检查，使工作？谢谢

            var httpClient = new HttpClient();
        var PK = ConfigurationManager.AppSettings["recaptchaKey"];//private key
        var userIP = ((HttpContextBase)this.Request.Properties["MS_HttpContext"]).Request.UserHostAddress;
        var uri = "http://www.google.com/recaptcha/api/verify";

        var postData = new List<KeyValuePair<string, string>>();
        postData.Add(new KeyValuePair<string, string>("privatekey", PK));
        postData.Add(new KeyValuePair<string, string>("remoteip", userIP));
        postData.Add(new KeyValuePair<string, string>("challenge", data.Challenge));
        postData.Add(new KeyValuePair<string, string>("response", data.Response));

        HttpContent content = new FormUrlEncodedContent(postData);

        string responseFromServer = await httpClient.PostAsync(uri, content)
                .ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode())
                .ContinueWith((readTask) => readTask.Result.Content.ReadAsStringAsync().Result);

        if (responseFromServer.StartsWith("true"))
        {
            return Contact(data);
        }
