获取 access_token 与获取 openid 方式一样具体如下：

服务端实现
/**
* 2.1 获取调用凭据 access_token
*/
private function get_access_token(){
$url ='https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=xxxxx&secret=xxxxx' ;
// 调用curl接口 获取数据
$access_token = $this->curl_request($url);
$access_token = json_decode($access_token);
return $access_token;
}
/**
* 参数1：访问的URL，
* 参数2：post数据(不填则为GET)
* 参数3：提交的$cookies
* 参数4：是否返回$cookies
*/
private function curl_request($url,$post='',$cookie='', $returnCookie=0){
header('Content-type:text/html; charset=utf-8'); //声明编码
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0)');
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
curl_setopt($curl, CURLOPT_REFERER, "http://XXX");
if($post) {
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
}
if($cookie) {
curl_setopt($curl, CURLOPT_COOKIE, $cookie);
}
curl_setopt($curl, CURLOPT_HEADER, $returnCookie);
curl_setopt($curl, CURLOPT_TIMEOUT, 10);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($curl);
if (curl_errno($curl)) {
return curl_error($curl);
}
curl_close($curl);
if($returnCookie){
list($header, $body) = explode("\r\n\r\n", $data, 2);
preg_match_all("/Set\-Cookie:([^;]*);/", $header, $matches);
$info['cookie'] = substr($matches[1][0], 1);
$info['content'] = $body;
return $info;
}else{
return $data;
}
}
