微信JSAPI 微信内置JSAPI 2015年1月官方正式API接口,分享完整实例
2015年1月30日,今天发现一些JS分享问题,一直很费解,通过查看原版开发手册,发现了根据原版的JSSDK进行修改补充。
主要用于微信浏览器分享朋友圈,转发好友等功能。
HTML通过微信,分享朋友圈出发此JSAPI
<?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接口只能在公众号绑定的域名下调用,公众号开发者需要先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”。 // 如果发现在 Android 不能分享自定义内容,请到官网下载最新的包覆盖安装,Android 自定义分享接口需升级至 6.0.2.58 版本及以上。 // 完整 JS-SDK 文档地址: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: [ // 所有要调用的 API 都要加到这个列表中 ] }); wx.ready(function () { // 在这里调用 API wx.onMenuShareTimeline({ title: '', // 分享标题 link: '', // 分享链接 imgUrl: '', // 分享图标 success: function () { // 用户确认分享后执行的回调函数 }, cancel: function () { // 用户取消分享后执行的回调函数 } }); wx.onMenuShareAppMessage({ title: '', // 分享标题 desc: '', // 分享描述 link: '', // 分享链接 imgUrl: '', // 分享图标 type: '', // 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 () { // 用户确认分享后执行的回调函数 }, cancel: function () { // 用户取消分享后执行的回调函数 } }); wx.onMenuShareQQ({ title: '', // 分享标题 desc: '', // 分享描述 link: '', // 分享链接 imgUrl: '', // 分享图标 success: function () { // 用户确认分享后执行的回调函数 }, cancel: function () { // 用户取消分享后执行的回调函数 } }); wx.onMenuShareWeibo({ title: '', // 分享标题 desc: '', // 分享描述 link: '', // 分享链接 imgUrl: '', // 分享图标 success: function () { // 用户确认分享后执行的回调函数 }, cancel: function () { // 用户取消分享后执行的回调函数 } }); }); </script> </html>
2.微信公众平台多用户分享JSSDK
<?php class JSSDK { private $appId; private $appSecret; public $User_ID; public function __construct($appId, $appSecret, $User_ID = 1) { $this->appId = $appId; $this->appSecret = $appSecret; $this->User_ID = $User_ID; } public function Ext_FileSystem(){ if(!file_exists("jSon_file/jsapi_ticket_".$this->User_ID.".json")){ touch("jSon_file/jsapi_ticket_".$this->User_ID.".json"); chmod("jSon_file/jsapi_ticket_".$this->User_ID.".json",0755); } if(!file_exists("jSon_file/access_token_".$this->User_ID.".json")){ touch("jSon_file/access_token_".$this->User_ID.".json"); chmod("jSon_file/access_token_".$this->User_ID.".json",0755); } } public function getSignPackage() { $this->Ext_FileSystem(); $jsapiTicket = $this->getJsApiTicket(); $url = "http://$_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 $data = json_decode(file_get_contents("jSon_file/jsapi_ticket_".$this->User_ID.".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; $fp = fopen("jSon_file/jsapi_ticket_".$this->User_ID.".json", "w"); fwrite($fp, json_encode($data)); fclose($fp); chmod("jSon_file/jsapi_ticket_".$this->User_ID.".json",0777); } } 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 $data = json_decode(file_get_contents("jSon_file/access_token_".$this->User_ID.".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; $fp = fopen("jSon_file/access_token_".$this->User_ID.".json", "w"); fwrite($fp, json_encode($data)); fclose($fp); chmod("jSon_file/access_token_".$this->User_ID.".json",0777); } } 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; } }
3.微信后台加密与算法
