谷歌分析特定帐户的无效凭据

Question

您好我正在使用其他帐户进行Google分析并返回错误：

GDataauthErrorAuthorizationInvalid Credentials

虽然我以前的帐户工作正常。可能是因为我错过了注册过程中的一些事情，任何人都可以给我一个详细的步骤，使用api_key for google analytics v2.4进行oauth 2.0的注册工作

谢谢

//returns session token for multiple calls to API
function get_session_token($onetimetoken) {

    if(preg_match("/Token=(.*)/", $output, $matches)) {
        $sessionToken = $matches[1];
    } else {
        echo "Error authenticating with Google.";
        exit;

    return $sessionToken;
