实际开发中 我这样写的：
1 //获取小程序码 2 public function getxcxm(){ 3 $id = input('id'); 4 //先从本地读取，本地没有再向微信提取 5 $ckname = ROOT_PATH . 'public/upload/recode/'.$id.".png"; 6 if(file_exists($ckname)){ 7 return str_replace("/www/wwwroot/","https://",$ckname); 8 }else{ 9 $astk = json_decode($this->getasstk())->access_token; 10 $url = "https://api.weixin.qq.com/wxa/getwxacode?access_token=".$astk; 11 $data = array( 12 'path' => "pages/app/querytest?id=".$id, 13 'width' => 430, 14 'is_hyaline' => true 15 ); 16 $xcxm = $this->http_request($url,json_encode($data)); 17 $path = ROOT_PATH . 'public/upload/recode/'; 18 if(!is_dir($path)){ 19 mkdir($path,0755,true); 20 } 21 $filepath = $path.$id.".png"; 22 $file = fopen($filepath,"w"); 23 fwrite($file,$xcxm); 24 fclose($file); 25 return str_replace("/www/wwwroot/","https://",$filepath); 26 } 27 }
