我是OAuth验证的新手,因为当我尝试访问Google的OAuth屏幕时,从未向我提供访问代码。我可以访问登录屏幕,然后如果我选择允许或拒绝,它会给我一个成功消息。没有错误,但有时会给出无效协议的例外,但我不知道这是为什么。适用于UWP的Google OAuth v2
,我使用的代码如下:
string state = GenerateRandomBase64Url(32);
string code_verifier = GenerateRandomBase64Url(32);
string code_challenge = GenerateBase64urlencodeNoPadding(sha256(code_verifier));
string clientID = "1037832553054-2ktd0l6dop546i1ti312r2doi63sglfe.apps.googleusercontent.com";
string redirectURI = "uwp.app:/oauth2redirect";
string authorizationEndpoint = "https://accounts.google.com/o/oauth2/v2/auth";
string tokenEndpoint = "https://www.googleapis.com/oauth2/v4/token";
string userInfoEndpoint = "https://www.googleapis.com/oauth2/v3/userinfo";
string youtubeScope = "https://www.googleapis.com/auth/youtube";
string code_challenge_method = "S256";
ApplicationDataContainer localSettings = ApplicationData.Current.LocalSettings;
localSettings.Values["state"] = state;
localSettings.Values["code_verifier"] = code_verifier;
string authorizationRequest = string.Format([email protected]"{authorizationEndpoint}?response_type=code&scope={Uri.EscapeDataString(youtubeScope)}&redirect_uri={Uri.EscapeDataString(redirectURI)}&client_id={clientID}&state={state}&code_challenge={code_challenge}&code_challenge_method={code_challenge_method}&login_hint={EmailBox.Text.Trim()}");
string endURL = "https://accounts.google.com/o/oauth2/approval?";
// I don't know if this is actually valid because google says that this Url is not available
Uri startURI = new Uri(authorizationRequest);
Uri endURI = new Uri(endURL);
string result = string.Empty;
try
{
//var success = Windows.System.Launcher.LaunchUriAsync(new Uri(authorizationRequest));
WebAuthenticationResult webAuthenticationResult = await WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.None, startURI, endURI);
switch (webAuthenticationResult.ResponseStatus)
{
// Successful authentication.
case WebAuthenticationStatus.Success:
result = webAuthenticationResult.ResponseData.ToString();
break;
// HTTP error.
case WebAuthenticationStatus.ErrorHttp:
result = webAuthenticationResult.ResponseErrorDetail.ToString();
break;
default:
result = webAuthenticationResult.ResponseData.ToString();
break;
}
}
catch (Exception ex)
{
result = ex.Message;
}
response.Text = result;
// the string that I get looks like this
// https://accounts.google.com/o/oauth2/approval?as=410b4db829b95fce&pageId=none&xsrfsign=AMt42IIAAAAAWO9e-l2loPR2RJ4_HzjfNiGJbiESOyoh
我不知道这是做在UWP应用程序的正确方法。此外,我从结果中获得的字符串不仅仅是一个Url,它不包含Google示例中所述的任何可视为code
的内容。 那么有人可以指出我在这里做错了吗?这应该很简单,但我不知道我做错了什么。谢谢
我已使用官方[代码示例](https://github.com/googlesamples/oauth-apps-for-windows)测试了Google OAuth v2的UWP。我使用'WebAuthenticationBroker.AuthenticateAsync'来获得Web认证结果。但是我无法重现您的问题,可以提供您的源代码,以便我可以针对此问题进行更多测试? –
嗯,我想这只是'endura'末尾'''的一个问题,我把它放在这里,但是我没有在我的实际代码中使用它,并且我以某种方式对它进行了整理。谢谢您的好意。 – Ahmar
