我正在尝试复制此处详述的流程; https://developers.google.com/accounts/docs/OAuth2WebServer#handlingtheresponse
在C＃中
String authorizationCode = String.Empty;
String consumerKey = String.Empty;
String consumerSecret = String.Empty;
String redirectUrl = String.Empty;
String grantType = String.Empty;
String requestContent = String.Empty;
HttpWebRequest request = null;
byte[] byteArray = null;
Stream dataStream = null;
WebResponse response = null;
StreamReader reader = null;
String serverResponse = String.Empty;
byte[] authorizationResult = null;
try
{
authorizationCode = HttpUtility.UrlEncode(context.Request.QueryString["code"]);
consumerKey = Properties.Settings.Default.GoogleConsumerKey;
consumerSecret = Properties.Settings.Default.GoogleConsumerSecret;
redirectUrl = Properties.Settings.Default.RedirectUrl;
grantType = "authorization_code";
request = (HttpWebRequest)WebRequest.Create("https://accounts.google.com/o/oauth2/token");
request.Method = "POST";
requestContent = String.Format("code={0}&client_id={1}&client_secret={2}&redirect_url={3}&grant_type={4}",authorizationCode,consumerKey,consumerSecret,redirectUrl,grantType);
byteArray = Encoding.UTF8.GetBytes(requestContent);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteArray.Length;
dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
response = request.GetResponse();
dataStream = response.GetResponseStream();
reader = new StreamReader(dataStream);
serverResponse = HttpUtility.UrlDecode(reader.ReadToEnd());
reader.Close();
dataStream.Close();
response.Close();
}
catch (System.Exception ex)
{
throw ex;
}
finally
{
}
麻烦就是在调用GetResponse（）时我收到了错误的请求。
ConsumerKey＆amp;秘密是我在注册申请时从谷歌那里得到的。 authorizationCode也来自Google。
任何想法我做错了什么？
提前致谢。
