Question

我可以通过从浏览器获取身份验证令牌并稍后使用“获取...”来获取访问权限。但我想在没有用户干预的情况下这样做。我决定使用服务帐户。但是当我想要访问时，我总是收到“拒绝访问”。我正在使用

var oAuth2Provider =
                (user.OAuthProvider as AdsOAuthProviderForServiceAccounts);
        oAuth2Provider.GenerateAccessTokenForServiceAccount();

oAuth2Provider的属性是：

JwtCertificatePassword“notasecret”
        JwtCertificatePath“D：//xxxxx-privatekey.p12”
        PrnEmail“jrusearchbroadtwomycc@gmail.com”//这是我的mcc帐号   批准的开发令牌
        ServiceAccountEmail“22222222222-ckvf630rcccn3j7jjuf4fmujnbiotett@developer.gserviceaccount.com”

这是错误的堆栈跟踪。

然后我读到了谷歌应用程序帐户的必要性。我已经注册，从我的服务帐户添加了它的帐户cliend id，看起来像

2222222222222-ckvf630rcccn3j7jjuf4fmujnbiotett.apps.googleusercontent.com 范围：https://adwords.google.com/api/adwords/

但我再次拒绝访问。

然后我尝试使用另一个看起来像的lib `

public static Dictionary<string, string> GetAccessToken(string clientIdEMail, string keyFilePath, string scope)
        {
            // certificate
            var certificate = new X509Certificate2(keyFilePath, "notasecret");

        // header
        var header = new { typ = "JWT", alg = "RS256" };

        // claimset
        var times = GetExpiryAndIssueDate();
        var claimset = new
        {
            iss = clientIdEMail,
            scope = scope,
            aud = "https://accounts.google.com/o/oauth2/token",
            iat = times[0],
            exp = times[1],
        };

        JavaScriptSerializer ser = new JavaScriptSerializer();

        // encoded header
        var headerSerialized = ser.Serialize(header);
        var headerBytes = Encoding.UTF8.GetBytes(headerSerialized);
        var headerEncoded = Convert.ToBase64String(headerBytes);

        // encoded claimset
        var claimsetSerialized = ser.Serialize(claimset);
        var claimsetBytes = Encoding.UTF8.GetBytes(claimsetSerialized);
        var claimsetEncoded = Convert.ToBase64String(claimsetBytes);

        // input
        var input = headerEncoded + "." + claimsetEncoded;
        var inputBytes = Encoding.UTF8.GetBytes(input);

        // signiture
        var rsa = certificate.PrivateKey as RSACryptoServiceProvider;
        var cspParam = new CspParameters
        {
            KeyContainerName = rsa.CspKeyContainerInfo.KeyContainerName,
            KeyNumber = rsa.CspKeyContainerInfo.KeyNumber == KeyNumber.Exchange ? 1 : 2
        };
        var aescsp = new RSACryptoServiceProvider(cspParam) { PersistKeyInCsp = false };
        var signatureBytes = aescsp.SignData(inputBytes, "SHA256");
        var signatureEncoded = Convert.ToBase64String(signatureBytes);

        // jwt
        var jwt = headerEncoded + "." + claimsetEncoded + "." + signatureEncoded;

        var client = new WebClient();
        client.Encoding = Encoding.UTF8;
        var uri = "https://accounts.google.com/o/oauth2/token";
        var content = new NameValueCollection();

        content["assertion"] = jwt;
        content["grant_type"] = "urn:ietf:params:oauth:grant-type:jwt-bearer";

        string response = Encoding.UTF8.GetString(client.UploadValues(uri, "POST", content));

        var result = ser.Deserialize<Dictionary<string, string>>(response);

        return result;
    }

    private static int[] GetExpiryAndIssueDate()
    {
        var utc0 = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
        var issueTime = DateTime.UtcNow;

        var iat = (int)issueTime.Subtract(utc0).TotalSeconds;
        var exp = (int)issueTime.AddMinutes(55).Subtract(utc0).TotalSeconds;

        return new[] { iat, exp };
    }`

之后 - 我收到了访问令牌和到期时间。

var result = GetAccessToken(SERVICE_ACCOUNT_EMAIL, SERVICE_ACCOUNT_PKCS12_FILE_PATH, SCOPE_ANALYTICS_READONLY);
            string access_token;
            result.TryGetValue("access_token", out access_token);

然后我正在尝试

oAuth2Provider.AccessToken = access_token;

但是再次接收访问被拒绝

我一直试图解决这个问题一个星期。

您真正想要实现的目标并非100％明显，但如果您需要代表用户进行离线访问，您可能需要的是“刷新令牌”，这样您就可以获得新的访问令牌当你的初始到期时。信息位于https://developers.google.com/accounts/docs/OAuth2WebServer

尝试通过oauth进行身份验证时拒绝访问
