1.根目錄下的/Application/Home/Controller文件夾中的UserController.class.php文件添加對應的方法，書寫代碼為：
~~~
<?php
namespace Home\Controller;
use Think\Controller;
use Com\Wechat;
use Com\WechatAuth;
class UserController extends Controller
{
private $appid="wx165112bf167af76c";
private $appSecret="c65b22bfcf03fdd98504eac299701b03";
private $WechatAuth="";//初始化WechatAuth類
private $access_token="";//緩存token
public function __construct(){
parent::__construct();//可能內部已經有這個構造方法了，因此加上這個
if(!session('token')){
$this->WechatAuth=new WechatAuth($this->appid,$this->appSecret);//初始化WechatAuth類
$WechatAuth=$this->WechatAuth;
$token=$WechatAuth->getAccessToken();
session(array('expire'=>$token['expires_in']));//設置過期時間
session('token',$token['access_token']);//緩存token
$this->access_token=$token;
}else{
$token=session('token');
$this->WechatAuth=new WechatAuth($this->appid,$this->appSecret,$token);//初始化WechatAuth類
$this->access_token=$token;//緩存token
}
}
//獲取所有用戶組
public function selectGroupsGet(){
header('Content-type:text/html;charset=utf-8;');
$WechatAuth=$this->WechatAuth;
$data=$WechatAuth->groupsGet();
var_dump($data);
}
//創建一個分組
public function createGroup(){
header('Content-type:text/html;charset=utf-8;');
$WechatAuth=$this->WechatAuth;
$data=$WechatAuth->groupsCreate('我的分組');
var_dump($data);
}
//查詢指定用戶的分組
public function GroupId(){
header('Content-type:text/html;charset=utf-8;');
$m=M('users');
$user=$m->find(1);//查詢users表中1d為1的數據
$openid=$user['openid'];
$WechatAuth=$this->WechatAuth;
$data=$WechatAuth->groupsGetid($openid);
var_dump($data);
}
}
