PHP實現微信分享朋友圈
1、先加載微信自帶的接口代碼
<?phpclass JSSDK {private $appId;private $appSecret;public function __construct($appId, $appSecret) {$this->appId = $appId;$this->appSecret = $appSecret;}public function getSignPackage() {$jsapiTicket = $this->getJsApiTicket();// 注意 URL 一定要動態獲取，不能 hardcode.$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";$url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";$timestamp = time();$nonceStr = $this->createNonceStr();// 這裏參數的順序要按照 key 值 ASCII 碼升序排序$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 $str;}private function getJsApiTicket() {// jsapi_ticket 應該全局存儲與更新，以下代碼以寫入到文件中做示例$data = json_decode($this->get_php_file("jsapi_ticket.php"));if ($data->expire_time < time()) {$accessToken = $this->getAccessToken();// 如果是企業號用以下 URL 獲取 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 = $ticket;$this->set_php_file("jsapi_ticket.php", json_encode($data));}} else {$ticket = $data->jsapi_ticket;}return $ticket;}private function getAccessToken() {// access_token 應該全局存儲與更新，以下代碼以寫入到文件中做示例$data = json_decode($this->get_php_file("access_token.php"));if ($data->expire_time < time()) {// 如果是企業號用以下URL獲取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 = $access_token;$this->set_php_file("access_token.php", json_encode($data));}} else {$access_token = $data->access_token;}return $access_token;}private function httpGet($url) {$curl = curl_init();curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);curl_setopt($curl, CURLOPT_TIMEOUT, 500);// 爲保證第三方服務器與微信服務器之間數據傳輸的安全性，所有微信接口採用https方式調用，必須使用下面2行代碼打開ssl安全校驗。// 如果在部署過程中代碼在此處驗證失敗，請到 http://curl.haxx.se/ca/cacert.pem 下載新的證書判別文件。curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);curl_setopt($curl, CURLOPT_URL, $url);$res = curl_exec($curl);curl_close($curl);return $res;}private function get_php_file($filename) {return trim(substr(file_get_contents($filename), 15));}private function set_php_file($filename, $content) {$fp = fopen($filename, "w");fwrite($fp, "<?php exit();?>" . $content);fclose($fp);}}
複製代碼
2、修改自己的配製信息用微信瀏覽器打開就可以了
<?phprequire_once "jssdk.php";$appid = 'wx110';$APPSECRET = '110';$jssdk = new JSSDK($appid, $APPSECRET);$signPackage = $jssdk->GetSignPackage();?><!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>js微信自定義分享標題、鏈接和圖標</title><meta name="keywords" content="js微信分享,php微信分享" /><meta name="description" content="PHP自定義微信分享內容，包括標題、圖標、鏈接等，分享成功和取消有js回調函數。" /></head><body></body><script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script><script>/** 注意：* 1. 所有的JS接口只能在公衆號綁定的域名下調用，公衆號開發者需要先登錄微信公衆平臺進入“公衆號設置”的“功能設置”裏填寫“JS接口安全域名”。* 2. 如果發現在 Android 不能分享自定義內容，請到官網下載最新的包覆蓋安裝，Android 自定義分享接口需升級至 6.0.2.58 版本及以上。* 3. 常見問題及完整 JS-SDK 文檔地址：http://mp.weixin.qq.com/wiki/7/aaa137b55fb2e0456bf8dd9148dd613f.html** 開發中遇到問題詳見文檔“附錄5-常見錯誤及解決辦法”解決，如仍未能解決可通過以下渠道反饋：* 郵箱地址：[email protected]* 郵件主題：【微信JS-SDK反饋】具體問題* 郵件內容說明：用簡明的語言描述問題所在，並交代清楚遇到該問題的場景，可附上截屏圖片，微信團隊會盡快處理你的反饋。*/wx.config({debug: false,appId: '<?php echo $appid; ?>',timestamp: <?php echo $signPackage["timestamp"]; ?>,nonceStr: '<?php echo $signPackage["nonceStr"]; ?>',signature: '<?php echo $signPackage["signature"]; ?>',jsApiList: ['onMenuShareTimeline']});wx.ready(function() {wx.onMenuShareTimeline({title: '二當家的', // 分享標題link: 'http://www.erdangjiade.com/', // 分享鏈接imgUrl: '', // 分享圖標success: function() {// 用戶確認分享後執行的回調函數},cancel: function() {// 用戶取消分享後執行的回調函數}});});</script><p style="text-align: center;color:red;font-size:20px;margin-top: 120px">請用微信瀏覽器打開，並打開右上方按鈕。分享到朋友圈試試。</p>
