微信门店接口在其他多个业务场景中都需要用到，如微信卡券、微信连WiFi等。在这些业务场景中，需要确定使用业务的门店有哪些，因此事先获取门店列表并保存有助于后续业务的开发。
微信门店的PHP SDK实现代码如下。
1 class class_wxpoint 2 { 3 var $appid = APPID; 4 var $appsecret = APPSECRET; 5 6 // 构造函数，获取Access Token 7 public function __construct($appid = NULL, $appsecret = NULL) 8 { 9 if($appid && $appsecret){10 $this->appid = $appid;11 $this->appsecret = $appsecret;12 }13 $res = file_get_contents('token.json');14 $result = json_decode($res, true);15 $this->expires_time = $result["expires_time"];16 $this->access_token = $result["access_token"];17 18 if (time > ($this->expires_time + 3600)){19 $url = "https:// api.weixin.qq.com/cgi-bin/token?grant_type=client_ credential&appid=".$this->appid."&secret=".$this->appsecret;20 $res = $this->http_request($url);21 $result = json_decode($res, true);22 $this->access_token = $result["access_token"];23 $this->expires_time = time;24 file_put_contents('token.json', '{"access_token": "'.$this->access_ token.'", "expires_time": '.$this->expires_time.'}');25 }26 }27 28 // 查询门店列表29 public function get_poi_list($begin = 0, $limit = 20)30 {31 $msg = array('begin' => $begin, 'limit' => $limit);32 $url = "https:// api.weixin.qq.com/cgi-bin/poi/getpoilist?access_token=". $this->access_token;33 $res = $this->http_request($url, urldecode(json_encode($msg)));34 return json_decode($res, true);35 }36 37 // HTTP请求（支持HTTP/HTTPS，支持GET/POST）38 protected function http_request($url, $data = null)39 {40 $curl = curl_init;41 curl_setopt($curl, CURLOPT_URL, $url);42 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);43 curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);44 if (!empty($data)){45 curl_setopt($curl, CURLOPT_POST, 1);46 curl_setopt($curl, CURLOPT_POSTFIELDS, $data);47 }48 curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);49 $output = curl_exec($curl);50 curl_close($curl);51 return $output;52 }53 } 调用获取门店ID列表的实现代码如下。
define('APPID', "wxfd3fd09f8b7c8f84");define('APPSECRET', "b45c1dd5152b35cfb3c7c70514decd04");$weixin = new class_wxpoint;$result = $weixin->get_poi_list;var_dump($result); 上述程序执行后的结果和15.1.4节的结果一致。
