最近在做一个投票项目涉及到微信公众号获取用户的openID，但是咧，之前做的微信公众号开发被我重装服务器系统的时候删除了，本地没有保存GG！！因此，发费了一天半的时间重新写了一遍。
当然，本次微信公众号开发基于thinkPHP3.2.3开发。

Access_Token、CURL、微信服务器IP Access_Token值是一个凭证，对于接下来的其它方面的功能的实现起到至关重要的作用。但是Access_Token每天只能有2000次的获取次数，每次有两个小时的有效期，因此我需要对其进行存储。存储有很多种方式：session、插入到数据库中等等。这里使用的是session方法。
/** * @return mixed * 获取access_token */ public function getAccessToken() { $appid = ''; $secret = ''; //如果access_token没有过期，直接return if ($_SESSION['access_token'] && $_SESSION['expire_time']>time() ){ return $_SESSION['access_token']; }else{ //重新获取access_token $url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$appid.'&secret='.$secret; $res = $this->http_curl($url,'get','json'); $_SESSION['access_token'] = $res['access_token']; $_SESSION['expire_time'] = time()+7200; return $res['access_token']; } }CURL这个很重要，每一次请求都需要执行一次它，因此，我们可以将它写成一个模板
/** * @param $url * @param string $type * @param string $res * @param string $arr * 万能请求 */ public function http_curl($url,$type='get',$res='json',$arr=''){ $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_SAFE_UPLOAD, FALSE); if ($type = 'post'){ curl_setopt($ch,CURLOPT_POST,1); curl_setopt($ch,CURLOPT_POSTFIELDS,$arr); } $output = curl_exec($ch); curl_close($ch); if ($res == 'json'){ return json_decode($output,true); } }微信服务器IP地址这个比较简单，看开发者文档可以解决，这里就不做详细说明。

自定义菜单栏
public function MenuBar() { $Access_Token = $this->getAccessToken(); header('content-type:text/html;charset=utf-8'); $url = 'https://api.weixin.qq.com/cgi-bin/menu/create?access_token='.$Access_Token; $arr = array( "button" => array( array( "name" => urlencode("功能"), "sub_button" => array( array( "type" => "click", "name" => urlencode("VIP视频解析"), "key" => "VIP" ), array( "type" => "click", "name" => urlencode("广州天气"), "key" => "tianqi" ), array( "type" => "view", "name" => urlencode("模板消息"), "url" => "http://soarteam.cn/wechat/index.php/Home/Index/Model" ), array( "type" => "view", "name" => urlencode("静默授权"), "url" => "http://soarteam.cn/wechat/index.php/Home/Index/ScopeBase" ), array( "type" => "view", "name" => urlencode("详细授权"), "url" => "http://soarteam.cn/wechat/index.php/Home/Index/ScopeUserinfo" ), ), ), array( "name" => urlencode("博客"), "sub_button" => array( array( "type" => "view", "name" => urlencode("我的博客"), "url" => "https://icharle.com" ), array( "type" => "view", "name" => urlencode("关于我"), "url" => "https://icharle.com/about.html" ), array( "type" => "view", "name" => urlencode("临时二维码"), "url" => "http://soarteam.cn/wechat/index.php/Home/Index/TempQRcode" ), array( "type" => "view", "name" => urlencode("永久二维码"), "url" => "http://soarteam.cn/wechat/index.php/Home/Index/LastQRcode" ), ), ), array( "name" => urlencode("Github"), "sub_button" => array( array( "type" => "view", "name" => urlencode("我的项目"), "url" => "https://github.com/icharle" ), array( "type" => "view", "name" => urlencode("超级课程表"), "url" => "https://github.com/icharle/jwxt" ), ), ), ), ); $postarr = urldecode(json_encode($arr)); $res = $this->http_curl($url,'post','json',$postarr); dump($res); } -

素材获取
新增临时素材：将文件中的
upload方法修改成如下，之后访问文件上传/** * 素材文件上传功能 */ public function upload() { if ($_FILES['file']!=""){ $upload = new \Think\Upload();// 实例化上传类 $upload->maxSize = 3145728 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg', 'mp3');// 设置附件上传类型 $upload->rootPath = './Upload/'; // 设置附件上传根目录 $upload->savePath = ''; // 设置附件上传（子）目录 $upload->saveName = ''; //保持原来的文件名 $upload->autoSub = false; //关闭子目录保存 // 上传文件 $info = $upload->upload(); $this->TempFile($info); //新增临时素材 }else{ $this->display(); } }新增永久素材：将文件中的
