原生php 实现微信自定义分享
不依赖任何框架,原生php 实现微信自定义分享:
不依赖任何框架,原生php 实现微信自定义分享:只需要两个文件:
index.php //模板文件
jssdk.php
index.php (模板代码如下):
自行替换 appId 和 appSecret
<?php include_once 'jssdk.php'; $jssdk = new /JSSDK("appId", "appSecret"); $signPackage = $jssdk->GetSignPackage(); $appid = 'appId'; $timestamp = $signPackage['timestamp']; $nonceStr = $signPackage['nonceStr']; $signature = $signPackage['signature'];?><script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script> <script> wx.config({ appId: '<?php echo $appid;?>', timestamp: '<?php echo $timestamp;?>', nonceStr: '<?php echo $nonceStr;?>', signature: '<?php echo $signature;?>', jsApiList: [ 'onMenuShareTimeline', 'onMenuShareAppMessage' ] }); wx.ready(function () { shareWeixin(); }); function shareWeixin(){ wx.onMenuShareTimeline({ title: '标题', link: '分享地址', imgUrl: '分享图片地址', success: function () { // 用户确认分享后执行的回调函数 //window.location.href=""; }, cancel: function () { // 用户取消分享后执行的回调函数 } }); wx.onMenuShareAppMessage({ title: '标题', desc: '简介', link: '分享地址', imgUrl: '分享图片地址', type: '', dataUrl: '', success: function () { // 用户确认分享后执行的回调函数 //window.location.href=""; }, cancel: function () { // 用户取消分享后执行的回调函数 } }); } </script>
jssdk.php 代码如下:
<?phpclass JSSDK { private $appId; private $appSecret; public function __construct($appId, $appSecret) { $this->appId = $appId; $this->appSecret = $appSecret; } public function getSignPackage() { $jsapiTicket = $this->getJsApiTicket(); $url = "http://www.51ask.org/"; $timestamp = time(); $nonceStr = $this->createNonceStr(); // 这里参数的顺序要按照 key 值 ASCII 码升序排序 $string = "jsapi_ticket=$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 应该全局存储与更新,以下代码以写入到文件中做示例 $data = json_decode(file_get_contents("jsapi_ticket.json")); if ($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 应该全局存储与更新,以下代码以写入到文件中做示例 $data = json_decode(file_get_contents("access_token.json")); if ($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; }}
