谷歌登陆demo之google授权api流程步骤

谷歌登陆示例代码：

<?php

header('Content-Type:text/html; charset=utf-8');

class Google
{
    protected $setting = [
        'app_id' => 'xx',          //客户端ID
        'app_secret' => 'xx',     //客户端密钥
        'redirect_uri' => 'xx',  //回调地址
    ];
    
    public function __construct($pf_game_id)
    {
        $this->client_id = $this->setting['app_id'];
        $this->client_secret = $this->setting['app_secret'];
        $this->redirect_uri = $this->setting['redirect_uri']."?pf_game_id=".$pf_game_id;
    }
    
    public function index()
    {
        //第一步：请求CODE
        if (empty($_GET['code'])) {
            $this->getCode($this->client_id, $this->redirect_uri);
        } else {
            //用户允许授权后，将会重定向到redirect_uri的网址上，并且带上code参数
            $code = $_GET['code'];
            $postData = array(
                'code' => $code,
                'client_id' => $this->client_id,
                'client_secret' => $this->client_secret,
                'redirect_uri' => $this->redirect_uri,
                'grant_type' => 'authorization_code'
            );
            //第二步：通过code获取access_token
            $purl = 'https://accounts.google.com/o/oauth2/token';
            $token = $this->CurlSend($postData,$purl);
            if (empty($token)) {
                exit("获取token失败");
            }
            echo "<pre>";print_r($token);die;
        }
    }
    
    /**
     * 抓取CODE
     * @param $client_id
     * @param $redirect_uris
     */
    protected function getCode($client_id, $redirect_uris)

        $url = "https://accounts.google.com/o/oauth2/auth?response_type=code&access_type=offline&client_id={$client_id}&redirect_uri={$redirect_uris}&state&scope={$scope}&approval_prompt=auto";
        header('Location:' . $url);
    }
    
    protected function CurlSend($postData, $purl)
    {
        $fields = (is_array($postData)) ? http_build_query($postData) : $postData;
        $curlHeaders = [
            'content-type: application/x-www-form-urlencoded;CHARSET=utf-8',
            'Content-Length: ' . strlen($fields),
        ];
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $purl);
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_HEADER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_HTTPHEADER, $curlHeaders);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $fields);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
        $response = curl_exec($curl);
        $responseCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
        curl_close($curl);
        if ($response && $responseCode == 200) {
            $json_data = json_decode($response, true);
            return $json_data;
        } else {
            return false;
        }
    }
    
    public function getATokenToRefToken($refresh_token){
        $url = 'https://accounts.google.com/o/oauth2/token';
        $postData = array(
            'client_id' => $this->client_id,
            'client_secret' => $this->client_secret,
            'grant_type' => 'refresh_token',
            'refresh_token' => $refresh_token
        );
        $token_data = $this->CurlSend($postData,$url);
        echo $token_data["access_token"];
    }
}

if(empty($_GET["pf_game_id"])){
    exit("pf_game_id is empty");
}

$google = new Google($_GET["pf_game_id"]);
$google->index();

完，有兴趣的自行测试！
