我阅读了Google OAuth2.0 for server to server application的文档,并尝试在线搜索,但找不到创建和续订OAuth2.0令牌的参考资料 Bigquery API 我尝试使用文档自行生成但仍然是徒劳的
请帮帮我
以下是我用来获取Json Web令牌的代码
<?php
$header = '{"alg":"RS256","typ":"JWT"}';
$header = base64_encode($header);
$claims = '{"iss":"account-1@euphoric-quanta-114611.iam.gserviceaccount.com","scope":"https://www.googleapis.com/auth/cloud-platform.read-only https://www.googleapis.com/auth/bigquery https://www.googleapis.com/auth/cloud-platform","aud":"https://www.googleapis.com/oauth2/v4/token","exp":"'.(time()+3000).'","iat":"'.time().'"}';
$claims = base64_encode($claims);
$encodedContent = $header . "." . $claims;
$signature = hash_hmac("SHA256",$encodedContent, '{my private key}');
$signature = base64_encode($signature);
$data = $header.".".$claims.".".$signature;
echo $data;
?>
稍后我将帖子请求发送到https://www.googleapis.com/oauth2/v4/token
,assertion
作为代码和grant_type=urn%3Aietf%3Aparams%3Aoauth%3Agrant-type%3Ajwt-bearer
生成的值,我得到了以下回复
{
"error": "invalid_grant",
"error_description": "Bad Request"
}
我犯了什么错误,在哪里可以找到有关Big Query API的JWT身份验证令牌的完整文档
提前致谢...
