执行完中提到的所有步骤后: https ://developers.google.com/identity/protocols/OAuth2ServiceAccount
并使用邮递员发出访问令牌请求:https: //www.googleapis.com/oauth2/v4/token
我收到以下错误:
"error": "invalid_grant",
"error_description": "Invalid JWT Signature."
我也尝试了没有 OAuth 的服务帐户授权,并收到错误:
{"error": {
"errors": [
{
"domain": "global",
"reason": "authError",
"message": "Invalid Credentials",
"locationType": "header",
"location": "Authorization"
}
],
"code": 401,
"message": "Invalid Credentials"
}
}
可能是什么问题,我该如何解决?
