微信JS-SDK PHP Demo JS接口安全域名 自定義分享接口 jsapi_ticket 分享到朋友圈 分享給朋友 分享到QQ
一、JSSDK類定義 <?php class JSSDK { private $appId; private $appSecret; public function __construct($appId, $appSecret) { $this->appId = $appId; $this->appSecret = $appSecret; } public function getSignPackage() { $jsapiTicket = $this->getJsApiTicket(); $url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; $timestamp = time(); $nonceStr = $this->createNonceStr(); // 這里參數(shù)的順序要按照 key 值 ASCII 碼升序排序 $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr×tamp=$timestamp&url=$url"; $signature = sha1($string); $signPackage = array( "appId" => $this->appId, "nonceStr" => $nonceStr, "timestamp" => $timestamp, "url" => $url, "signature" => $signature, "rawString" => $string ); return $signPackage; } private function createNonceStr($length = 16) { $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; $str = ""; for ($i = 0; $i < $length; $i++) { $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1); } return $str; } private function getJsApiTicket() { // jsapi_ticket 應(yīng)該全局存儲(chǔ)與更新，以下代碼以寫入到文件中做示例 $data = json_decode(file_get_contents("jsapi_ticket.json")); if ($data->expire_time < time()) { $accessToken = $this->getAccessToken(); $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken"; $res = json_decode($this->httpGet($url)); $ticket = $res->ticket; if ($ticket) { $data->expire_time = time() + 7000; $data->jsapi_ticket = $ticket; $fp = fopen("jsapi_ticket.json", "w"); fwrite($fp, json_encode($data)); fclose($fp); } } else { $ticket = $data->jsapi_ticket; } return $ticket; } private function getAccessToken() { // access_token 應(yīng)該全局存儲(chǔ)與更新，以下代碼以寫入到文件中做示例 $data = json_decode(file_get_contents("access_token.json")); if ($data->expire_time < time()) { $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret"; $res = json_decode($this->httpGet($url)); $access_token = $res->access_token; if ($access_token) { $data->expire_time = time() + 7000; $data->access_token = $access_token; $fp = fopen("access_token.json", "w"); fwrite($fp, json_encode($data)); fclose($fp); } } else { $access_token = $data->access_token; } return $access_token; } private function httpGet($url) { $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); curl_setopt($curl, CURLOPT_URL, $url); $res = curl_exec($curl); curl_close($curl); return $res; } }
二、類調(diào)用<?php require_once "jssdk.php"; $jssdk = new JSSDK("yourAppID", "yourAppSecret"); $signPackage = $jssdk->GetSignPackage(); ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title></title> </head> <body> </body> <script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script> <script> // 注意：所有的JS接口只能在公眾號(hào)綁定的域名下調(diào)用，公眾號(hào)開發(fā)者需要先登錄微信公眾平臺(tái)進(jìn)入“公眾號(hào)設(shè)置”的“功能設(shè)置”里填寫“JS接口安全域名”。 // 如果發(fā)現(xiàn)在 Android 不能分享自定義內(nèi)容，請(qǐng)到官網(wǎng)下載最新的包覆蓋安裝，Android 自定義分享接口需升級(jí)至 6.0.2.58 版本及以上。 // 完整 JS-SDK 文檔地址：http://mp.weixin.qq.com/wiki/7/aaa137b55fb2e0456bf8dd9148dd613f.html wx.config({ appId: '<?php echo $signPackage["appId"];?>', timestamp: <?php echo $signPackage["timestamp"];?>, nonceStr: '<?php echo $signPackage["nonceStr"];?>', signature: '<?php echo $signPackage["signature"];?>', jsApiList: [ // 所有要調(diào)用的 API 都要加到這個(gè)列表中 ] }); wx.ready(function () { // 在這里調(diào)用 API }); </script> </html>
