如何通过php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
^ajax(Common.ServerUrl + "GetWX.php", { data: { Type: "config", url: location.href.split('#')[0] }, dataType: 'json', type: 'get', timeout: 5000, success: function(data) { wx.config({ debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打樱 appId: '……', // 必填,公众号的唯一标识 timestamp: data.timestamp, // 必填,生成签名的时间戳 nonceStr: data.nonceStr, // 必填,生成签名的随机串 signature: data.signature, // 必填,签名,见附录1 jsApiList: ["getLocation"] // 必填,需要使用的JS接口列表,所有JS接口列表见附录2 }); } }) wx.ready(function() { wx.getLocation({ type: 'wgs84', // 默认为wgs84的gps坐标,如果要返回直接给openLocation用的火星坐标,可传入'gcj02' success: function(res) { var latitude = res.latitude; // 纬度,浮点数,范围为90 ~ -90 var longitude = res.longitude; // 经度,浮点数,范围为180 ~ -180。 plus2.storage.setItem("latitude", latitude); plus2.storage.setItem("longitude", longitude); } }); });
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=".$noncestr."×tamp=".$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 = 'https://api.weixin.qq.com/cgi-bin/ticket/getticket'; $data = array('type'=>'jsapi','access_token'=>$access_token); $header = array(); $response = json_decode(curl_https($url, $data, $header, 5)); $jsapi_ticket = $response->ticket; //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 = 'https://api.weixin.qq.com/cgi-bin/token'; $data = array('grant_type'=>'client_credential','appid'=>$APPID,'secret'=>$SECRET); $header = array(); $response = json_decode(curl_https($url, $data, $header, 5)); $access_token = $response->access_token; //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)) {//can't 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 } } ?>
