I trying to make authorized API call (HTTP/REST) to service account in Google Analytics. using this doc: https://developers.google.com/identity/protocols/OAuth2ServiceAccount
我只是使用HTTP / REST请求进行测试。
所以我有服务帐户的私钥文件:
{
"type": "service_account",
"project_id": "test-x",
"private_key_id": "some_private_key_id",
"private_key": "-----BEGIN PRIVATE KEY----- some_private_key -----END PRIVATE KEY-----",
"client_email": "test-01@test-x.iam.gserviceaccount.com",
"client_id": "some_client_id",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://accounts.google.com/o/oauth2/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/test-01%40test-x.iam.gserviceaccount.com"
}
我基于创建JWT client_email: test-01@test-x.iam.gserviceaccount.com
部首:
{"alg":"RS256","typ":"JWT"}
索赔集:
{
"iss": "test-01@test-x.iam.gserviceaccount.com",
"scope": "https://www.googleapis.com/auth/analytics.readonly",
"aud": "https://www.googleapis.com/oauth2/v4/token",
"exp": 1488820112,
"iat": 1488816522
}
iat - 我只是设置了当前的
exp - 当前+ 1小时,
我使用此服务创建签名:https://jwt.io/#debugger
它生成我尝试用于访问令牌请求的编码值
当我尝试使用“编码”字段中的生成结果时:
curl -d 'grant_type=urn%3Aietf%3Aparams%3Aoauth%3Agrant-type%3Ajwt-bearer&assertion=JWT_that_has_been_signed' https://www.googleapis.com/oauth2/v4/token
结果:
{
"error": "invalid_grant",
"error_description": "Invalid JWT Signature."
}
但我没有使用我的私钥。 根据计算签名的文档,我必须使用我的私钥。 我不完全理解如何正确使用密钥来正确计算签名。
jwt.io已生成PUBLIC和PRIVATE密钥......
可能我正在使用jwt.io错误..
请告诉我创建JWT的正确方法,或者可能是另一项创建JWT的服务。
谢谢!

我遇到了同样的问题,
我只是从(.*)
.*
google cloud platform
“ 项目名称”
已经创建了您的服务帐户,单击 IAM & admin -> Service accounts
并更新项目上的私钥。希望对您有帮助。

对于研究此问题的任何人,我都有一组PHP代码,用于获取带有JSON服务帐户文件的令牌。该PHP代码段将为您提供用于获取GA数据的令牌。
// assume $config is your json service account file converted to array
$config = "YOUR JSON FILE CONVERTED TO ARRAY";
$jwt_header = '{"alg":"RS256","typ":"JWT"}';
$jwt_header_cryph = urlencode(base64_encode($jwt_header));
$jwt_claim = '{
"iss": "'.$config['client_email'].'",
"scope":"https://www.googleapis.com/auth/analytics.readonly",
"aud":"https://www.googleapis.com/oauth2/v4/token",
"exp":'.(time()+3600).',
"iat":'.time().'
}';
$jwt_claim_cryph = urlencode(base64_encode($jwt_claim));
$data = $jwt_header_cryph.".".$jwt_claim_cryph;
$binary_signature = "";
$algo = "SHA256";
openssl_sign($data, $binary_signature, $config['private_key'], $algo);
$jws_signature_cryph = urlencode(base64_encode($binary_signature));
//concatenating the jwt request to complete it
$complete_request = $jwt_header_cryph.".".$jwt_claim_cryph.".".$jws_signature_cryph;
//build CURL request with post method
$url = 'https://www.googleapis.com/oauth2/v4/token';
//set POST variables
$fields = array(
'grant_type' => urlencode('urn:ietf:params:oauth:grant-type:jwt-bearer'),
'assertion' => $complete_request
);
$fields_string = "";
//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true );
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
$token = json_decode($result, true);
变量$token
将具有以下内容
[
"access_token" => "your-access-token-string"
"expires_in" => 3599
"token_type" => "Bearer"
]
使用access_token
字符串ping通GA以获取分析数据。
希望这对某人有帮助,因为在任何地方都无法很好地解释此问题,因此需要进行一些挖掘才能正确地找到加密。

当密钥不再有效时,我收到此错误。我生成了一个新的服务帐号密钥并开始工作。
