我可以通过从浏览器获取身份验证令牌并稍后使用“Fetch ...”来访问。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。但是当我尝试访问时,我总是收到“访问被拒绝”。我在用着
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 帐户,带有已批准的开发令牌
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需求。我已经注册,从我的服务帐户添加到它的帐户客户 ID,看起来像
2222222222222-ckvf630rcccn3j7jjuf4fmujnbiotett.apps.googleusercontent.com 范围:https ://adwords.google.com/api/adwords/
但是我再次被拒绝访问。
然后我尝试使用另一个看起来像`
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 };
}`
在那之后-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);
然后我试图
oAuth2Provider.AccessToken = access_token;
但再次接收访问被拒绝
我已经尝试解决这个问题一周了。
