静态页面分享如何带缩略图、标题和描述

今天早上361模板给大家介绍了《实例分析微信分享网页链接缩略图不显示解决方法》。可能很多朋友看得不是很明白，因为没有代码，也不知道如何操作，下面361模板就详细给大家深入介绍一下静态页面分享如何带缩略图、标题和描述。

首先，我们需要在服务端引入jssdk.php文件

代码如下：

appId = $appId;        $this->appSecret = $appSecret;    $this->url = $url;      }      public function getSignPackage() {        $jsapiTicket = $this->getJsApiTicket();        $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";       // $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";    $url =$this->url;        $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";    //这里经常出问题,一般都是这里出现问题，要留意      $signature = sha1($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 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 < time()) {          $accessToken = $this->getAccessToken();          // 如果是企业号用以下 URL 获取 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;            $fp = fopen("jsapi_ticket.json", "w");            fwrite($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 < time()) {          // 如果是企业号用以下URL获取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;            $fp = fopen("access_token.json", "w");            fwrite($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;      }    }     $jssdk = new JSSDK("APPID", "APPSECRET",$url);//按照自己的公众号填写    $signPackage = $jssdk->GetSignPackage();    // var_dump($signPackage);  $tmp=json_encode(array ('appId'=>$signPackage["appId"],'timestamp'=>$signPackage["timestamp"],'nonceStr'=>$signPackage["nonceStr"],'signature'=>$signPackage["signature"],'url'=>$signPackage["url"]));    $callback = $_GET['callback'];    echo $callback.'('.$tmp.')';    exit;    ?>

将上述文件，上传到空间后，做第二步。

第二步、静态页面js代码

<script src="https://res.wx.qq.com/open/js/jweixin-1.2.0.js"></script>    <script>    url = location.href.split('#')[0];  url = encodeURIComponent(url);      $.ajax({        type : "get",        url : "http://xxxxx.com/jssdk.php?url="+url,//替换网址，xxx根据自己jssdk文件位置修改        dataType : "jsonp",        jsonp: "callback",        jsonpCallback:"success_jsonpCallback",        success : function(data){            wx.config({           debug:false,   appId: data.appId,    timestamp: data.timestamp,    nonceStr: data.nonceStr,    signature: data.signature,    jsApiList: [           "onMenuShareTimeline", //分享给好友           "onMenuShareAppMessage", //分享到朋友圈           "onMenuShareQQ",  //分享到QQ           "onMenuShareWeibo" //分享到微博    ]    });    },                    error:function(data){                        alert("连接失败！");                    }    });      wx.ready(function (){      var shareData = {      title: '更换标题',      desc: '更换内容',//这里请特别注意是要去除html      link: '更换链接',      imgUrl: '更换图片'      };      wx.onMenuShareAppMessage(shareData);      wx.onMenuShareTimeline(shareData);      wx.onMenuShareQQ(shareData);      wx.onMenuShareWeibo(shareData);        });    </script>

到这里通过以上2步就能实现静态页面分享带缩略图、标题和描述了。快去尝试看看吧。
