如何在没有授权重定向URI的情况下从Blogger获取访问令牌？

Before I ask this question. I search and see the topic "Using OAuth 2.0 to Access Google APIs - PHP Code Example" from http://rscavilla.blogspot.com/2011/06/using-oauth-20-with-php-to-authenticate.html

This example when I get access token from blogger. I must allow access. But I don't want to access permission the Google Account.

My purpose is I want to get access token via php curl without access permission the Google Account for create new post to blogger.

UPDATE

    return $inputs;
}

Now, I can access to approve application page for get code from redirect url.

Approve application page for manage blogger account.
