微信分享的网络请求及方法

前端ajax调用分享接口

    $(function(){
        wx.config({
            debug: false,
            appId: '{$signPackage["appId"]}',
            timestamp: '{$signPackage["timestamp"]}',
            nonceStr: '{$signPackage["nonceStr"]}',
            signature: '{$signPackage["signature"]}',
            jsApiList: [
                // 所有要调用的 API 都要加到这个列表中
                'onMenuShareTimeline','onMenuShareAppMessage'
            ]
        });
        wx.ready(function () {
            // 在这里调用 API
            wx.onMenuShareTimeline({
                title: '{$slogan["title"]}', // 分享标题
                desc: '{$slogan["desc"]}',//分享描述
                link: '{$slogan["url"]}', // 分享链接
                imgUrl: '{$slogan["img"]}', // 分享图标
                success: successShare,
            });
            wx.onMenuShareAppMessage({
                title: '{$slogan["title"]}', // 分享标题
                desc: '{$slogan["desc"]}',//分享描述
                link: '{$slogan["url"]}', // 分享链接
                imgUrl: '{$slogan["img"]}',// 分享图标
                success: successShare,
            });
        });

        function successShare () {
            var post_url = '?g=TT&m=Lottery&a=successShare';
            {literal}
            var post_data = {'share':1};
            {/literal}
            //分享成功后 增加抽奖机会
            $.post(post_url,post_data,'json');
            $(".share_nav").fadeOut();
        }
    });

后台接收到ajax请求之后，分享成功，则执行方法

//成功分享活动  若今日未达到 NUM 次，抽奖机会+1
    public function successShare()
    {
        if (!IS_AJAX) return false;

        $actLotteryRecordModel = D('ActLotteryRecord'); //抽奖记录模型
        $actLotteryTicketModel = D('ActLotteryTicket');


        if ($_REQUEST['share'] == 1) {
            $records = $actLotteryRecordModel->get_lottery_record($this->_user['user_id']);
            if (count($records) < self::NUM) $actLotteryTicketModel->insert($this->_user['user_id'], 2);
        }

    }

或者后台设置微信分享后的标题、内容、图标

//获取微信分享信息
    private function assignShareConf()
    {
        import('@.Com.weixin.jssdk', '', '.php');
        $wx_conf = OpenPlatformConf::weixin_conf();
        $jssdk = new JSSDK($wx_conf['app_id'], $wx_conf['app_secret']);
        $signPackage = $jssdk->GetSignPackage();

        $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
        $url = "$protocol$_SERVER[HTTP_HOST]";

        $slogan = array(
            'title' => 'Come On！别拦我！我找抽！',
            'desc'  => '你过来，我找抽！百分百中奖，8888元体验金、百万彩票、智能手表等你来!',
            'img'   => $url.'/tpl_dev/TT/weixin/images/Lottery/bgi12.png',
            'url'   => '',
        );

        $this->assign(array(
                'signPackage' => $signPackage,
                'slogan' => $slogan,
            )
        );
    }
