摘要：用戶要分享的網(wǎng)址又更分享的標(biāo)題分享的圖片又更僅僅如此分享的描述信息請在之后引入

直接上代碼

目錄（jssdk在網(wǎng)站更目錄）

jssdk/jssdk.php
jssdk/share.js

jssdk.php 代碼如下

appId = $appId;
    $this->appSecret = $appSecret;
    $this->url = $url;//2017-06-27
  }

  public function getSignPackage() {
    $jsapiTicket = $this->getJsApiTicket();

    // 注意 URL 一定要動態(tài)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]";//2017-06-27
    $url =$this->url;//2017-06-27
    
    $timestamp = time();
    $nonceStr = $this->createNonceStr();

    // 這里參數(shù)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(yīng)該全局存儲與更新，以下代碼以寫入到文件中做示例
    $data = json_decode(file_get_contents("jsapi_ticket.json"));
    if ($data->expire_time < time()) {
      $accessToken = $this->getAccessToken();
      // 如果是企業(yè)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;
        $fp = fopen("jsapi_ticket.json", "w");
        fwrite($fp, json_encode($data));
        fclose($fp);
      }
    } else {
      $ticket = $data->jsapi_ticket;
    }

    return $ticket;
  }

  private function getAccessToken() {
    // access_token 應(yīng)該全局存儲與更新，以下代碼以寫入到文件中做示例
    $data = json_decode(file_get_contents("access_token.json"));
    if ($data->expire_time < time()) {
      // 如果是企業(yè)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;
        $fp = fopen("access_token.json", "w");
        fwrite($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, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true); //https
    curl_setopt($curl, CURLOPT_URL, $url);

    $res = curl_exec($curl);
    curl_close($curl);

    return $res;
  }
}
$jssdk = new JSSDK("AAPID", "appSecret",$url);
$signPackage = $jssdk->GetSignPackage();
$tmp=json_encode(array ("appId"=>$signPackage["appId"],"timestamp"=>$signPackage["timestamp"],"nonceStr"=>$signPackage["nonceStr"],"signature"=>$signPackage["signature"],"url"=>$signPackage["url"]));
$callback = $_GET["callback"];
echo $callback."(".$tmp.")";
exit;
?>

share.js代碼如下

//url = location.href;
var url = encodeURIComponent(window.location.href);//去掉簽名
$.ajax({
    type: "get",
    url: "../jssdk/jssdk.php?url=" + url,
    dataType: "jsonp",
    jsonp: "callback",
    jsonpCallback: "success_jsonpCallback",
    success: function(data) {
        wx.config({
            appId: data.appId,
            timestamp: data.timestamp,
            nonceStr: data.nonceStr,
            signature: data.signature,
            jsApiList: ["chackJsApi", "onMenuShareTimeline", "onMenuShareAppMessage", "onMenuShareQQ", "onMenuShareWeibo", "onMenuShareQZone"]
        });
    },
    error: function(data) {
        alert("連接失敗！");
    }
});
wx.ready(function() {
    var shareData = {

        title: title,
        desc: desc,
        link: url,
        imgUrl: img,
        success: function(res) {
            //分享成功
        },
        cancel: function(res) {
            alert("已取消分享");
        }
    };
    wx.onMenuShareAppMessage(shareData);
    wx.onMenuShareTimeline(shareData);
    wx.onMenuShareQQ(shareData);
    wx.onMenuShareWeibo(shareData);
    wx.onMenuShareQZone(shareData);
});

部署方式 頁面底部添加如下代碼

在引用jweixin-1.0.0.js之前，重置define、require即可。

ps：請在jquery之后引入
