首先確保你的公眾號配置沒有問題，詳細請看： PHP 微信公眾號-創建菜單-配置
1、獲取簽名包
這裏需要你的appid 和 開發者密碼
//獲取簽名包 public function getSignPackage() { $jsapiTicket = $this->getJsApiTicket(); $url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; $timestamp = time(); $nonceStr = $this->createNonceStr();View Code// 這裏參數的順序要按照 key 值 ASCII 碼升序排序 $tmpArr = array( ‘noncestr‘ => $nonceStr, ‘timestamp‘ => $timestamp, ‘jsapi_ticket‘ => $jsapiTicket, ‘url‘ => $url ); ksort($tmpArr, SORT_STRING); $string1 = http_build_query( $tmpArr); $string1 = urldecode( $string1 ); $signature = sha1( $string1 ); $signPackage = array( "appId" => $this->appid, "nonceStr" => $nonceStr, "timestamp" => $timestamp, "url" => $url, "signature" => $signature, "rawString" => $string1 ); return $signPackage; } //獲取jsapi_ticket private function getJsApiTicket() { if (S(‘jsapi_ticket_‘.$this->appid)) { $ticket = S(‘jsapi_ticket_‘.$this->appid); } else { $accessToken = $this->getToken($this->appid, $this->appsecret); $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken"; $res = $this->request_get($url); $ticket = $res[‘ticket‘]; if ($ticket) { S(‘jsapi_ticket_‘.$this->appid, $ticket, 7200); } } return $ticket; } /** * @param $appid * @param $appsecret * @return mixed * 獲取token */ public function getToken($appid, $appsecret){ if (S($appid)) { $access_token = S($appid); } else { $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $appid . "&secret=" . $appsecret; $json = file_get_contents($url); $result = json_decode($json); $access_token = $result->access_token; S($appid, $access_token, 7200); } return $access_token; } /** * 發送get請求 * @param string $url * @return bool|mixed */ function request_get($url = ‘‘){ if (empty($url)) { return false; } $json = file_get_contents($url); $result = json_decode($json,true); return $result; } public function createNonceStr($length = 16) { $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; $str = ""; for ($i = 0; $i < $length; $i++) { $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1); } return $str; }
2、php控制器 配置圖文消息內容，圖片等。獲取的簽名包也要渲染到分享的頁面
$invite = array(
"Title" => ‘標題‘, "Description" => ‘摘要內容‘, "PicUrl" => ‘圖片地址‘, "Url" => ‘要分享的頁面（就是點擊圖文進入的頁面）‘ );
3、頁面
首先要引入官方JS：jweixin-1.0.0.js
!function(a,b){"function"==typeof define&&(define.amd||define.cmd)?define(function(){return b(a)}):b(a,!0)}(this,function(a,b){function c(b,c,d){a.WeixinJSBridge?WeixinJSBridge.invoke(b,e(c),function(a){g(b,a,d)}):j(b,d)}function d(b,c,d){a.WeixinJSBridge?WeixinJSBridge.on(b,function(a){d&&d.trigger&&d.trigger(a),g(b,a,c)}):d?j(b,d):j(b,c)}function e(a){return a=a||{},a.appId=z.appId,a.verifyAppId=z.appId,a.verifySignType="sha1",a.verifyTimestamp=z.timestamp+"",a.verifyNonceStr=z.nonceStr,a.verifySignature=z.signature,a}function
