thinkphp与微信JSSDK结合分享实例
新建CommonController.class.php来获取
appId: '', // 必填，公众号的唯一标识
timestamp: , // 必填，生成签名的时间戳
nonceStr: '', // 必填，生成签名的随机串
signature: '',// 必填，签名<?php namespace Home\Controller; use Think\Controller; class CommonController extends Controller { public function _initialize() { $jssdk = new JSSDK("您的ID", "您的ACCESS"); $signPackage = $jssdk->GetSignPackage(); $this->assign('signPackage',$signPackage); } } //微信方法 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(); // 这里参数的顺序要按照 key 值 ASCII 码升序排序 $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$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 $str .= substr($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 $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 $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$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; } }下面就可以使用了
新建IndexController.class.php<?php namespace Home\Controller; use Think\Controller; class IndexController extends CommonController { public function index(){ $this->display(); } }html文件中添加<script></script> <script> wx.config({ appId: '{$signPackage.appId}', timestamp: {$signPackage.timestamp}, nonceStr: '{$signPackage.nonceStr}', signature: '{$signPackage.signature}', jsApiList: [ 'checkJsApi', 'onMenuShareTimeline', 'onMenuShareAppMessage', 'onMenuShareQQ', 'onMenuShareWeibo' ] }); wx.ready(function () { // 1 判断当前版本是否支持指定 JS 接口，支持批量判断 wx.checkJsApi({ jsApiList: [ 'getNetworkType', 'previewImage', 'onMenuShareTimeline', 'onMenuShareAppMessage', 'onMenuShareQQ', 'onMenuShareWeibo' ], }); var shareData = { //标题 title: '标题', //摘要 desc: '摘要', //链接,可以换主页 link: '{$signPackage.url}', //缩略图 imgUrl: '缩略图', }; wx.onMenuShareAppMessage(shareData); wx.onMenuShareTimeline(shareData); wx.onMenuShareQQ(shareData); wx.onMenuShareWeibo(shareData); }); </script>之后就大功告成
