Question

我可以很好地获取访问密钥，但在尝试使用以下代码获取令牌时，我收到了（400）错误请求错误。我尝试了一切。我知道凭据是正确的，因为它们与Google API客户端配合使用。话虽这么说，我不能使用它，因为我需要这个在3.5框架中运行。这里有什么明显的错误吗？

private const string clientId = "1003120056405-ofafvc699hjujp0a9952g8vjaludk90j.apps.googleusercontent.com";
private const string clientSecret = "******************";
private string redirectURI = "urn:ietf:wg:oauth:2.0:oob:auto";


public static AuthResponse Exchange(string authCode, string clientid, string secret, string redirectURI){


try
        {


            var request = (HttpWebRequest)WebRequest.Create("https://accounts.google.com/o/oauth2/token");

            string postData = string.Format("code={0}&client_id={1}&client_secret={2}&redirect_uri={3}&grant_type=authorization_code&scope={4}", HttpUtility.UrlEncode(authCode), clientid, secret, redirectURI, "");

            var data = Encoding.ASCII.GetBytes(postData);

            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded; charset=utf-8";
            request.ContentLength = data.Length;


            using (var stream = request.GetRequestStream())
            {

                stream.Write(data, 0, data.Length);
            }

            var response = (HttpWebResponse)request.GetResponse();


            var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
            MessageBox.Show(responseString);
            return null;


        }

        catch (WebException ex)
        {
            MessageBox.Show(ex.Message);
            return null;
        }
    }

我得到了这个工作。上面的代码很好，但我的accessKey被错误地转换为小写。密钥区分大小写以检查令牌。
