php一个文件搞定微信jssdk配置

　　php一个文件搞定微信jssdk配置：

　　包括缓存，包括https通讯，获取微信access_token，签名什么的都有。但是防范性编程做得比较少，商业用的话，需要完善下代码。

　　使用姿势

　　服务端

　　GetWX.php

　　 <?php include lib/Cache.php; define($APPID, ……); define($SECRET, ……) if($_GET[Type] == access_token){ // echo getAccess_token(); } else if($_GET[Type] == jsapi_ticket){ // echo getJsapi_ticket(); } else if($_GET[Type] == config){ $jsapi_ticket = getJsapi_ticket(); $nonceStr = x.rand(10000,100000).x; //随机字符串 $timestamp = time(); //时间戳 $url = $_GET[url]; $signature = getSignature($jsapi_ticket,$nonceStr, $timestamp, $url); $result = array(jsapi_ticket=>$jsapi_ticket, nonceStr=>$nonceStr,timestamp=>$timestamp,url=>$url,signature=>$signature); echo json_encode($result); } function getSignature($jsapi_ticket,$noncestr, $timestamp, $url){ $string1 = jsapi_ticket=.$jsapi_ticket.&noncestr=.$noncestr.&timestamp=.$timestamp.&url=.$url; $sha1 = sha1($string1); return $sha1; } function getJsapi_ticket(){ $cache = new Cache(); $cache = new Cache(7000, cache/); //需要创建cache文件夹存储缓存文件。 //从缓存从读取键值 $key 的数据 $jsapi_ticket = $cache -> get(jsapi_ticket); $access_token = getAccess_token(); //如果没有缓存数据 if ($jsapi_ticket == false) { $access_token = getAccess_token(); $url = 写入键值 $key 的数据 $cache -> put(jsapi_ticket, $jsapi_ticket); } return $jsapi_ticket; } function getAccess_token(){ $cache = new Cache(); $cache = new Cache(7000, cache/); //从缓存从读取键值 $key 的数据 $access_token = $cache -> get(access_token); //如果没有缓存数据 if ($access_token == false) { $url = 写入键值 $key 的数据 $cache -> put(access_token, $access_token); } return $access_token; } /** curl 获取 https 请求 * @param String $url 请求的url * @param Array $data 要發送的數據 * @param Array $header 请求时发送的header * @param int $timeout 超时时间，默认30s */ function curl_https($url, $data=array(), $header=array(), $timeout=30){ $ch = curl_init(); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查 curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); $response = curl_exec($ch); if($error=curl_error($ch)){ die($error); } curl_close($ch); return $response; } ?>

　　Cache.php
不知道哪位写的源代码~

　　 <?php class Cache { private $cache_path; //path for the cache private $cache_expire; //seconds that the cache expires //cache constructor, optional expiring time and cache path public function Cache($exp_time = 3600, $path = cache/) { $this -> cache_expire = $exp_time; $this -> cache_path = $path; } //returns the filename for the cache private function fileName($key) { return $this -> cache_path . md5($key); } //creates new cache files with the given data, $key== name of the cache, data the info/values to store public function put($key, $data) { $values = serialize($data); $filename = $this -> fileName($key); $file = fopen($filename, w); if ($file) {//able to create the file fwrite($file, $values); fclose($file); } else return false; } //returns cache for the given key public function get($key) { $filename = $this -> fileName($key); if (!file_exists($filename) !is_readable($filename)) {//cant read the cache return false; } if (time() < (filemtime($filename) + $this -> cache_expire)) {//cache for the key not expired $file = fopen($filename, r); // read data file if ($file) {//able to open the file $data = fread($file, filesize($filename)); fclose($file); return unserialize($data); //return the values } else return false; } else return false; //was expired you need to create new } } ?>
