這段時間公司的項目中有用到分享自定義標題和圖片的東西,從微信官方文檔中認真看了一下 其實特別簡單,可能對新手來講會有點繞,這裏我用PHP來講明一下。php
我從微信官方文檔中下載的sample說明,看了一下,裏面的分享頁是用PHP格式的,可是個人項目中是html格式的,因此我想着不改動的格式的話怎麼來實現,因而從網上那種趴,結果發現答案五花八門,都是說要改爲PHP的;還有就是須要後臺配合的,下面給你們講的是將php寫在本地的,在界面中直調取就好;廢話不說啦,直接上圖html
上面是個人目錄結構 wxjdk是我從sample中下載的拿的php裏面的東西ajax
access_token.php 、 jsapi_ticket.php 、jssdk直接拿到過來就好json
jssdk 說一下我作修改的部分及注意點api
<?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 必定要動態獲取,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"; $this->set_log_file("[getSignPackage]".$string); $signature = sha1($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,如下代碼以寫入到文件中作示例 $data = json_decode($this->get_php_file("jsapi_ticket.php")); if ($data->expire_time < time()) { $accessToken = $this->getAccessToken(); // 若是是企業號用如下 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)); $this->set_log_file("[getJsApiTicket]".json_encode($res)); $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,如下代碼以寫入到文件中作示例 $data = json_decode($this->get_php_file("access_token.php")); if ($data->expire_time < time()) { // 若是是企業號用如下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)); $this->set_log_file("[getAccessToken]".json_encode($res)); $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($curl, CURLOPT_TIMEOUT, 500); // 爲保證第三方服務器與微信服務器之間數據傳輸的安全性,全部微信接口採用https方式調用,必須使用下面2行代碼打開ssl安全校驗。 // 若是在部署過程當中代碼在此處驗證失敗,請到 http://curl.haxx.se/ca/cacert.pem 下載新的證書判別文件。 //從官方下載的jssdk中下面這倆應該是true,我這給改爲false啦,由於個人分享是http開頭的,兩種狀況下,若是你分享中jsapi_ticket和 access_token中寫不進去值,先看一下你的是分享連接是什麼開頭的,http的話就改爲false curl_setopt($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 $res; } private function get_php_file($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); } //這裏是給加了個日誌,官網下載無,能夠不加; public function set_log_file($content){ $logfile = "wx.log"; $content = date('Y-m-d H:i:s.u').' '.$content."\n"; $fp = fopen($logfile, "a"); fwrite($fp, $content); fclose($fp); } }
接下來是改寫的一些東西
ajax_getconfig.php安全
<?php require_once "jssdk.php"; $jssdk = new JSSDK("你的Appid", "你的secret",$_GET['url']); $signPackage = $jssdk->GetSignPackage(); $signPackage['jsApiList'] = array('onMenuShareTimeline','onMenuShareAppMessage'); $signPackage['debug'] = false; echo json_encode($signPackage); ?>
function_share.js服務器
function Share(url,title,img,desc){ //須要說明的一點,在這裏 ./ 表示的是你的根目錄; $.get("./wxjdk/ajax_getconfig.php",{url:window.location.href},function(data) { // console.log(data) wx.config(data); wx.ready(function () { // 在這裏調用 API wx.onMenuShareTimeline({ //例如分享到朋友圈的API title: title, // 分享標題 link: url, // 分享連接 imgUrl: img, // 分享圖標 success: function () { alert('分享成功') }, cancel: function () { // 用戶取消分享後執行的回調函數 } }); wx.onMenuShareAppMessage({ title: title, // 分享標題 desc: desc, // 分享描述 link: url, // 分享連接 imgUrl: img, // 分享圖標 type: '', // 分享類型,music、video或link,不填默認爲link dataUrl: '', // 若是type是music或video,則要提供數據連接,默認爲空 success: function () { alert('分享成功') }, cancel: function () { // 用戶取消分享後執行的回調函數 } }); wx.error(function (res) { alert(res.errMsg); //打印錯誤消息。及把 debug:false,設置爲debug:ture就能夠直接在網頁上看到彈出的錯誤提示 }); }); }, "json" ); }
最後一步就是在an_share.html中引入微信的jweixin-1.2.0.js 和 function_share.js 而後調用Share函數啦!微信
