我可以通过从浏览器获取身份验证令牌并稍后使用“获取...”访问权限。 但我想在没有用户干预的情况下做到这一点。 我决定使用服务帐户。 但是,当我试图访问, 我总是收到“访问被拒绝”。 我使用尝试通过oauth进行身份验证时访问被拒绝

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

oAuth2Provider的特性是:

JwtCertificatePassword “notasecret”
JwtCertificatePath “d://xxxxx-privatekey.p12”
PrnEmail“jrusearchbroadtwomycc @ gmail的。 com“//这是我的mcc账号 已批准的开发人员令牌
ServiceAccountEmail”[email protected]ccount.com“

以下是错误的堆栈跟踪。

然后我已阅读了关于谷歌应用程序帐户的需求。 我已经注册,加入到它的帐户cliend ID从看起来像

2222222222222-ckvf630rcccn3j7jjuf4fmujnbiotett.apps.googleusercontent.com 范围我的服务帐户:https://adwords.google.com/api/adwords/

,但我得到的访问再次否认。

然后我试图使用其他的lib,它看起来像 `

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 }; 
    }` 

这 - 我收到后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); 

然后我试图

oAuth2Provider.AccessToken = access_token; 

但再次接受访问被拒绝

我一直在试图解决这个问题的一个星期。

我解决了它。 我现在正在使用谷歌应用帐户来检索对API的访问。 而且我已将此帐户注册为我的客户中心。 – Aidanpraid

这并不是100%显而易见的,但是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”,因此您可以获得新的访问权限当您的第一个到期时,您会收到代币信息是在https://developers.google.com/accounts/docs/OAuth2WebServer

我试图在没有用户干预的情况下访问。它每天晚上都会在我们的服务器上启动。 所以我不会有机会获得访问令牌手动 – Aidanpraid
