這篇文章主要為大家展示了“php如何實(shí)現(xiàn)微信jssdk配置”,內(nèi)容簡而易懂,條理清晰,希望能夠幫助大家解決疑惑,下面讓小編帶領(lǐng)大家一起研究并學(xué)習(xí)一下“php如何實(shí)現(xiàn)微信jssdk配置”這篇文章吧。
php一個(gè)文件搞定微信jssdk配置:
包括緩存,包括https通訊,獲取微信access_token,簽名什么的都有。但是防范性編程做得比較少,商業(yè)用的話,需要完善下代碼。
使用姿勢
^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, // 開啟調(diào)試模式,調(diào)用的所有api的返回值會在客戶端alert出來,若要查看傳入的參數(shù),可以在pc端打開,參數(shù)信息會通過log打出,僅在pc端時(shí)才會打印。 appId: '……', // 必填,公眾號的唯一標(biāo)識 timestamp: data.timestamp, // 必填,生成簽名的時(shí)間戳 nonceStr: data.nonceStr, // 必填,生成簽名的隨機(jī)串 signature: data.signature, // 必填,簽名,見附錄1 jsApiList: ["getLocation"] // 必填,需要使用的JS接口列表,所有JS接口列表見附錄2 }); } }) wx.ready(function() { wx.getLocation({ type: 'wgs84', // 默認(rèn)為wgs84的gps坐標(biāo),如果要返回直接給openLocation用的火星坐標(biāo),可傳入'gcj02' success: function(res) { var latitude = res.latitude; // 緯度,浮點(diǎn)數(shù),范圍為90 ~ -90 var longitude = res.longitude; // 經(jīng)度,浮點(diǎn)數(shù),范圍為180 ~ -180。 plus2.storage.setItem("latitude", latitude); plus2.storage.setItem("longitude", longitude); } }); });
服務(wù)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"; //隨機(jī)字符串 $timestamp = time(); //時(shí)間戳 $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/'); //需要創(chuàng)建cache文件夾存儲緩存文件。 //從緩存從讀取鍵值 $key 的數(shù)據(jù) $jsapi_ticket = $cache -> get("jsapi_ticket"); $access_token = getAccess_token(); //如果沒有緩存數(shù)據(jù) if ($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; //寫入鍵值 $key 的數(shù)據(jù) $cache -> put("jsapi_ticket", $jsapi_ticket); } return $jsapi_ticket; } function getAccess_token(){ $cache = new Cache(); $cache = new Cache(7000, 'cache/'); //從緩存從讀取鍵值 $key 的數(shù)據(jù) $access_token = $cache -> get("access_token"); //如果沒有緩存數(shù)據(jù) if ($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; //寫入鍵值 $key 的數(shù)據(jù) $cache -> put("access_token", $access_token); } return $access_token; } /** curl 獲取 https 請求 * @param String $url 請求的url * @param Array $data 要發(fā)送的數(shù)據(jù) * @param Array $header 請求時(shí)發(fā)送的header * @param int $timeout 超時(shí)時(shí)間,默認(rèn)30s */ function curl_https($url, $data=array(), $header=array(), $timeout=30){ $ch = curl_init(); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // 跳過證書檢查 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
不知道哪位寫的源代碼~
<?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 } } ?>
