之前写过几次 没有保存过,现在整理下。
首先是php 的 JSDK
<?php class JSSDK { private $appId; private $appSecret; public function __construct($appId, $appSecret) { $this->appId = $appId; $this->appSecret = $appSecret; } public function getSignPackage() { $jsapiTicket = $this->getJsApiTicket(); // 注意 URL 一定要动态获取,不能 hardcode. $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://"; $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; $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(); // 如果是企业号用以下 URL 获取 ticket // $url = "https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token=$accessToken"; $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$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()) { // 如果是企业号用以下URL获取access_token // $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret"; $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$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_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl, CURLOPT_URL, $url); $res = curl_exec($curl); curl_close($curl); return $res; } }
New 的时候传入对应的APPID 以及 APPSECRET 。
然后是JS 部分
<script src="https://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script> <script> wx.config({ debug: false, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。 appId: '{$appid}', // 必填,公众号的唯一标识 timestamp:{$timestamp} , // 必填,生成签名的时间戳 nonceStr: '{$nonceStr}', // 必填,生成签名的随机串 signature: '{$signature}',// 必填,签名,见附录1 jsApiList: ['onMenuShareAppMessage','onMenuShareTimeline'] // 必填,需要使用的JS接口列表,所有JS接口列表见附录2 }); wx.ready(function(){ //分享给朋友 wx.onMenuShareAppMessage({ title:'', // 分享标题 此处$title可在控制器端传递也可在页面传递 页面传递讲解在下面哦 desc:'', //分享描述 link:'', // 分享链接 imgUrl: '', // 分享图标 type: 'link', // 分享类型,music、video或link,不填默认为link dataUrl: '', // 如果type是music或video,则要提供数据链接,默认为空 success: function (data) { alert('分享好友成功'); }, cancel: function () { // 用户取消分享后执行的回调函数 alert('取消分享'); } }); //分享到朋友圈 wx.onMenuShareTimeline({ title:'', // 分享标题 desc: '', // 分享描述 link:'', // 分享链接 imgUrl:'', // 分享图标 success: function () { alert('分享朋友圈成功'); // 用户确认分享后执行的回调函数 }, cancel: function(){ alert('取消分享'); // 用户取消分享后执行的回调函数 } }); }); </script>
