【在小程序中获取openId，附加具体代码】2.后台 php端代码：

//获取openId function getOpenId($code) { $url = 'https://api.weixin.qq.com/sns/jscode2session?appid=' . $this->appid . '&secret=' . $this->secret . '&js_code=' . $code . '&grant_type=authorization_code'; return $this->getHTTPS($url); }//获取https页面信息 function getHTTPS($url) { $ch = curl_init(); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_REFERER, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); $result = curl_exec($ch); curl_close($ch); return $result; }//封装到公共的方法之后在其它php中调用，并返回 public function openId() { $code = $this->request->post('code'); echo $this->getOpenId($code); }
