微信开发之上传临时素材介绍

public function uploadImg($imgUrl){   $TOKEN=$this->getAccessToken();  $URL ='http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token='.$TOKEN.'&type=image';  $data = array('media'=>'@'.$imgUrl);  $result = $this->curl_post($URL,$data);  $data = @json_decode($result,true);     return $data['media_id']; }  public function getAccessToken(){   $url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=wxe574b1bd35d7d4da&secret=d4624c36b6795d1d99dcf0547af5443d';     $result = json_decode($this->curlGet($url),true);   return $result['access_token']; }  function curl_post($url, $data = null){ //创建一个新cURL资源 $curl = curl_init(); //设置URL和相应的选项 curl_setopt($curl, CURLOPT_URL, $url); if (!empty($data)){  curl_setopt($curl, CURLOPT_POST, 1);  curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); //执行curl，抓取URL并把它传递给浏览器 $output = curl_exec($curl); //关闭cURL资源，并且释放系统资源 curl_close($curl); return $output;}

调用uploadImg($imgurl) 传图片地址参数
返回结果

array ( 'type' => 'image', 'media_id' => 'W89mt3FEaxXOMOw0fLj2Cb6A8vfMjuXrj6XW59O3l9a7Tj_h2SjlBEr4dvp4Du2R', 'created_at' => 1464140301,）
