第一步：
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>上传素材</title></head><body><form action="/wxmenu/uploadImage" method="post" enctype="multipart/form-data"><p><input type="file" name="media" id=""><input type="submit" value="提交素材"></p></form></body></html>
第二步：
在wxmenu的控制器中添加方法
public function action_uploadImage(){$files = $_FILES['media'];// 得到扩展名$extname = pathinfo($files['name'], PATHINFO_EXTENSION);//上传到服务器的路径$url = '/upload/banner/';$name = time().'.'.$extname;$realpath = $url.$name;move_uploaded_file($files['tmp_name'], $realpath);echo $this->uploadMaterial($realpath);}
private function uploadMaterial($path){$upload_url = "https://api./cgi-bin/material/add_material?access_token=".Utils::get_access_token()."&type=image";$json = $this->http_request_post($upload_url, [], $path);// json转为数组$arr = json_decode($json, true);p($arr);return $arr['media_id'];}private function http_request_post($url, $data, $file=''){if(!empty($file)){$data['media'] = new CURLFile($file);}$curl = curl_init();curl_setopt($curl, CURLOPT_URL, $url);curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,FALSE);curl_setopt($curl, CURLOPT_POST, 1);curl_setopt($curl, CURLOPT_POSTFIELDS, $data);curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);$output = curl_exec($curl);//判断有无出错if (curl_errno($curl) > 0){echo curl_error($curl);$output = 'http请求出错！'.'['.curl_error($curl).']';}curl_close($curl);return $output;}
获取access_token
public static function get_access_token(){$redis = new Redis();$redis->connect('127.0.0.1', 7001);$redis->auth('123456');$time = $redis->ttl('access_token');if($time > 0){$access_token = $redis->get('access_token');}else{$appid = "123456"; //需替换成你的appID$appsecret = "123456"; //需替换成你的appsecret$url = "https://api./cgi-bin/token?grant_type=client_credential&"."appid=$appid&secret=$appsecret";$output = Utils::https_request($url);$jsoninfo = json_decode($output, true);$access_token = $jsoninfo["access_token"];$redis->setex('access_token',7200,$access_token);}return $access_token;}
亲测可用！！！
