二、配置ip白名单

三、填写APPID

<?php
    // 步骤1.设置appid和appsecret
    $appid='填写APPID';
    $appsecret = '填写APPSECRET';
 
    // 步骤2.生成签名的随机串
    function nonceStr($length){
        $str = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';//62个字符
        $strlen = 62;
        while($length > $strlen){
        $str .= $str;
        $strlen += 62;
        }
        $str = str_shuffle($str);
        return substr($str,0,$length);
    }
 
    // 步骤3.获取access_token
    $result = http_get('https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$appid.'&secret='.$appsecret);
    $json = json_decode($result,true);
    $access_token = $json['access_token'];
 
    function http_get($url){
        $oCurl = curl_init();
        if(stripos($url,"https://")!==FALSE){
            curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, FALSE);
            curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, FALSE);
            curl_setopt($oCurl, CURLOPT_SSLVERSION, 1); //CURL_SSLVERSION_TLSv1
        }
        curl_setopt($oCurl, CURLOPT_URL, $url);
        curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1 );
        $sContent = curl_exec($oCurl);
        $aStatus = curl_getinfo($oCurl);
        curl_close($oCurl);
        if(intval($aStatus["http_code"])==200){
            return $sContent;
        }else{
            return false;
        }
    }
 
    // 步骤4.获取ticket
    $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$access_token";
    $res = json_decode ( http_get ( $url ) );
    $ticket = $res->ticket;

 
    // 步骤5.生成wx.config需要的参数
    $surl = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
    $ws = getWxConfig( $ticket,$surl,time(),nonceStr(16) );
  var_dump($ws);
    function getWxConfig($jsapiTicket,$url,$timestamp,$nonceStr) {
        $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url";
        $signature = sha1 ( $string );
 
        $WxConfig["appId"] ='填写APPID';
        $WxConfig["nonceStr"] = $nonceStr;
        $WxConfig["timestamp"] = $timestamp;
        $WxConfig["url"] = $url;
        $WxConfig["signature"] = $signature;
        $WxConfig["rawString"] = $string;
        return $WxConfig;
    }

?>

四、配置js，直接复制粘贴过去就可以

<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script>
  wx.config({
      debug: false,
      appId: '<?php echo $ws["appId"]; ?>',
      timestamp: '<?php echo $ws["timestamp"]; ?>',
      nonceStr: '<?php echo $ws["nonceStr"]; ?>',
      signature: '<?php echo $ws["signature"]; ?>',
      jsApiList: [
          'checkJsApi',
          'onMenuShareTimeline',
          'onMenuShareAppMessage',
          'onMenuShareQQ',
          'onMenuShareWeibo',
          'onMenuShareQZone',
      ]
  });
 
  var wstitle = "页面标题";
  var wsdesc = "页面描述";
  var wslink = "<?php echo $surl; ?>";
  var wsimg = "图片地址";
 
</script>
<script>

wx.ready(function () {
    // 分享到朋友圈
    wx.onMenuShareTimeline({
        title: wstitle,
        link: wslink,
        imgUrl: wsimg,
        success: function () {
            alert('分享成功');
        },
        cancel: function () {
        }
    });
 
    // 分享给朋友
    wx.onMenuShareAppMessage({
        title: wstitle,
        desc: wsdesc,
        link: wslink,
        imgUrl: wsimg,
        success: function () {
          alert('分享成功');
        },
        cancel: function () {
        }
    });
 
    // 分享到QQ
    wx.onMenuShareQQ({
        title: wstitle,
        desc: wsdesc,
        link: wslink,
        imgUrl: wsimg,
        success: function () {
            alert('分享成功');
        },
        cancel: function () {
        }
    });
 
    // 微信到腾讯微博
    wx.onMenuShareWeibo({
        title: wstitle,
        desc: wsdesc,
        link: wslink,
        imgUrl: wsimg,
        success: function () {
            alert('分享成功');
        },
        cancel: function () {
        }
    });
 
    // 分享到QQ空间
    wx.onMenuShareQZone({
        title: wstitle,
        desc: wsdesc,
        link: wslink,
        imgUrl: wsimg,
        success: function () {
            alert('分享成功');
        },
        cancel: function () {
        }
    });
 
});
</script>
