製作授權頁面

這裏我們直接修改welcome的index方法，代碼如下：

   public function index()
    {
        $tbnick = get_cookie('taobao_user_nick');
        $etime = get_cookie('expire_time');
        $tbserid = get_cookie('taobao_user_id');
        $session = get_cookie('access_token' );


        $data = array(
            'taobao_user_nick' => $tbnick,
            'expire_time' => $etime,
            'taobao_user_id' => $tbserid,
            'access_token' => $session
        );

        $this->load->view('welcome_message',$data);
    }

模板代碼，由於頁面簡單，用pure的CSS框架。

拼接授權鏈接

上面的頁面，主要是爲了方面用戶操作，同時爲了友好顯示，把用戶授權後的信息又給保存了下來。

https://oauth.taobao.com/authorize?response_type=code&client_id=25307802&redirect_uri=http://vipapi.dahuariji.com/index.php/welcome/oauth&state=vipapi&view=web

處理回調內容

用戶正常授權後，我們取回所需要的內容。

public function oauth()
    {
        $url = 'https://oauth.taobao.com/token';
        $postfields = array('grant_type' => 'authorization_code',
            'client_id' => '你的appkey',
            'client_secret' => '你的appkey',
            'code' => $_GET['code'],
            'redirect_uri' => 'http://vipapi.dahuariji.com/index.php/welcome/oauth');
        $post_data = '';
        foreach ($postfields as $key => $value) {
            $post_data .= "$key=" . urlencode($value) . "&";
        }
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        //指定post數據
        curl_setopt($ch, CURLOPT_POST, true);
        //添加變量
        curl_setopt($ch, CURLOPT_POSTFIELDS, substr($post_data, 0, -1));
        $output = curl_exec($ch);
        curl_close($ch);
        $j = json_decode($output);
        $tbnick = $j->taobao_user_nick;
        $etime = $j->expire_time;
        $openuid = $j->taobao_open_uid;
        $tbserid = $j->taobao_user_id;
        $session = $j->access_token;


        $data = array(
            'taobao_user_nick' => $tbnick,
            'expire_time' => $etime,
            'taobao_open_uid' => $openuid,
            'taobao_user_id' => $tbserid,
            'access_token' => $session
        );

        if ($session) {
            set_cookie('taobao_user_nick',$tbnick,2592000);
            set_cookie('expire_time',$etime,2592000);
            set_cookie('taobao_user_id',$tbserid,2592000);
            set_cookie('access_token' , $session,2592000);
            //入庫
            $querys = $this->users_model->get_user($tbserid);
            if ($querys->num_rows() == 1)
            {
                $query = $this->users_model->update_user($data);
            }
            else
            {
                $query = $this->users_model->insert_user($data);
            }
            //

        }
        //$this->load->view('welcome_show',$data);
        //跳轉到額新頁面展示
        redirect("http://vipapi.dahuariji.com/index.php/welcome/showuid/".$tbserid);
    }

這裏爲了顯示簡單點，跳轉到新的頁面，簡單的顯示了下。

    
    public function showuid()
{
    $uid = $this->uri->segment(3);
    $data =array('uid' => $uid);
    $this->load->view('welcome_show',$data);
}

數據庫的基本操作，增刪改查

  public function get_user_by_name($taobao_user_nick)
    {
        $query = $this->db->get_where('usertoken', array('taobao_user_nick' => $taobao_user_nick), 0,1);
        return $query;
    }

    public function get_user($taobao_user_id)
    {
        $query = $this->db->get_where('usertoken', array('taobao_user_id' => $taobao_user_id), 0,1);
        return $query;
    }

    public function insert_user($data)
    {
        return $this->db->insert('usertoken', $data);
    }

    public function update_user($data)
    {
        return $this->db->replace('usertoken', $data);
    }

這樣一個基本的session授權管理就做好了。
