PHP 微信分享页面（图文）
首先确保你的公众号配置没有问题，详细请看： PHP 微信公众号-创建菜单-配置
1、获取签名包
这里需要你的appid 和 开发者密码
//获取签名包 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 $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 $signPackage; } //获取jsapi_ticket private function getJsApiTicket() { if (S('jsapi_ticket_'.$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 $appsecret * @return mixed * 获取token */ public function getToken($appid, $appsecret){ if (S($appid)) { $access_token = S($appid); } else { $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&app>; $json = file_get_contents($url); $result = json_decode($json); $access_token = $result->access_token; S($appid, $access_token, 7200); } return $access_token; } /** * 发送get请求 * @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 配置图文消息内容，图片等。获取的签名包也要渲染到分享的页面
$invite = array(
"Title" => '标题', "Description" => '摘要内容', "PicUrl" => '图片地址', "Url" => '要分享的页面（就是点击图文进入的页面）' );
3、页面
首先要引入官方JS：jweixin-1.0.0.js
