Php 谷歌oauth认证

我试图通过授权，然后从google plus获取数据，但数据变量始终显示“暂时移动”的值。我做错了什么

<?php
session_start();

    $client_id = '';
    $client_secret = '';
    $api_key = '';
    $redirect_uri = 'http://localhost:8888/oauth';
    $scope = "https://www.googleapis.com/auth/plus.me";

    if (!isset($_REQUEST['code']))
    {
        $login_path = "https://accounts.google.com/o/oauth2/auth?";
        $login_path .= "redirect_uri=" . $redirect_uri;
        $login_path .= "&response_type=code";
        $login_path .= "&client_id=" . $client_id;
        $login_path .= "&approval_prompt=force";
        $login_path .= "&scope=" . $scope;
        $login_path .= "&access_type=offline";

        echo "<a href='" . $login_path . "'>login</a>";
    }

    else
    {

        $ch = curl_init();

        curl_setopt($ch, CURLOPT_URL, "https://accounts.google.com/o/oauth2/auth");

        curl_setopt($ch, CURLOPT_POST, TRUE);

        // This option is set to TRUE so that the response
        // doesnot get printed and is stored directly in
        // the variable
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

        $post_params = "code=" . $_REQUEST['code'] . "&";
        $post_params = "redirect_uri=" . $redirect_uri . "&";
        $post_params .= "client_id=" . $client_id . "&";
        $post_params .= "scope=" . $scope . "&";
        $post_params .= "client_secret=" . $client_secret . "&";
        $post_params .= "grant_type=authorization_code&";
        $post_params .= "response_type=code";


        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_params);

        $data = curl_exec($ch);

        curl_close($ch);

        //commented this since data was showing empty
        //$data = json_decode($data);

        print '<pre>';
        print $data;
        print '</pre>';
}

更新：对于其他有同样问题的人，我已经解决了。这是我的工作代码


$client_id=''；
$client_secret=''；
$api_key=''；
$redirect_uri='1http://localhost:8888/oauth';
$scope=”https://www.googleapis.com/auth/plus.me";
$api_调用=”https://www.googleapis.com/plus/v1/people/me?access_token=";
如果（！isset（$_请求['code']））
{
$login_path=”https://accounts.google.com/o/oauth2/auth?";
$login\u path.=“redirect\u uri=”.$redirect\u uri；
$login\u path.=“&response\u type=code”；

其他的

$post_参数=“授权类型=授权代码&”；
curl_setopt（$ch，CURLOPT_POSTFIELDS，$post_params）；

卷曲关闭（$ch）；
$data=json_decode（$data）；
$access\u token=$data->access\u token；
$refresh\u token=$data->refresh\u token；
//oauth的末尾现在调用google plus api。not$api\u调用保存请求uri值
$call=$api\u call.$access\u令牌；
