我找到了答案我在寻找。我不得不PHP转换为MVC,但很容易:
http://codecri.me/case/430/get-a-users-google-email-address-via-oauth2-in-php/
我的MVC Login
沙箱代码如下所示。 (使用JSON.Net http://json.codeplex.com/)
public ActionResult Login()
{
string url = "https://accounts.google.com/o/oauth2/auth?";
url += "client_id=<google-clientid>";
url += "&redirect_uri=" +
// Development Server :P
HttpUtility.UrlEncode("http://localhost:61857/Account/OAuthVerify");
url += "&scope=";
url += HttpUtility.UrlEncode("http://www.google.com/calendar/feeds/ ");
url += HttpUtility.UrlEncode("http://www.google.com/m8/feeds/ ");
url += HttpUtility.UrlEncode("http://docs.google.com/feeds/ ");
url += HttpUtility.UrlEncode("https://mail.google.com/mail/feed/atom ");
url += HttpUtility.UrlEncode("https://www.googleapis.com/auth/userinfo.email ");
url += HttpUtility.UrlEncode("https://www.googleapis.com/auth/userinfo.profile ");
url += "&response_type=code";
return new RedirectResult(url);
}
返回的code
是从用户,然后需要被转成Authentication
(的accessToken)来访问资源Authorization
令牌的证明。 我的MVC OAuthVerify
则看起来像:
public ActionResult AgentVerify(string code)
{
JObject json;
if (!string.IsNullOrWhiteSpace(code))
{
NameValueCollection postData = new NameValueCollection();
postData.Add("code", code);
postData.Add("client_id", "<google-clientid>");
postData.Add("client_secret", "<google-client-secret>");
postData.Add("redirect_uri", "http://localhost:61857/Account/OAuthVerify");
postData.Add("grant_type", "authorization_code");
try
{
json = JObject.Parse(
HttpClient.PostUrl(
new Uri("https://accounts.google.com/o/oauth2/token"), postData));
string accessToken = json["access_token"].ToString();
string refreshToken = json["refresh_token"].ToString();
bool isBearer =
string.Compare(json["token_type"].ToString(),
"Bearer",
true,
CultureInfo.CurrentCulture) == 0;
if (isBearer)
{
json = JObject.Parse(
HttpClient.GetUrl(
new Uri("https://www.googleapis.com/oauth2/v1/userinfo?alt=json"),
accessToken));
string userEmail = json["email"].ToString();
}
return View("LoginGood");
}
catch (Exception ex)
{
ErrorSignal.FromCurrentContext().Raise(ex); //ELMAH
}
}
return View("LoginBad");
}
要完成的一切是如何工作的,已经包含了我的情况下,任何人创建HttpClient的程序需要它。
public class HttpClient
{
public static string GetUrl(Uri url, string OAuth)
{
string result = string.Empty;
using (WebClient httpClient = new WebClient())
{
httpClient.Headers.Add("Authorization","OAuth " + OAuth);
result = httpClient.DownloadString(url.AbsoluteUri);
}
return result;
}
public static string PostUrl(Uri url, NameValueCollection formData)
{
string result = string.Empty;
using (WebClient httpClient = new WebClient())
{
byte[] bytes = httpClient.UploadValues(url.AbsoluteUri, "POST", formData);
result = Encoding.UTF8.GetString(bytes);
}
return result;
}
}
再次,这是测试代码只是为了让它正常工作,我不建议在生产环境中使用它。
我遇到同样的问题。你有没有找到解决方案/解决方法? – ascandroli 2011-05-14 11:22:57
