【技】微信开发，分享到朋友圈、QQ、空间等api接口方法使用

项目在微信端开发，要求在宝贝详情页，分享到朋友圈等渠道，别人点击分享跳到网站，带该邀请人的邀请id等

• 1.调用微信的接口，初始化页面时，就要把要把该页面（需要分享的页面）init

添加注册渠道标示
   function init (){
         var invite_type = 2;   //如果该宝贝被分享，则记录邀请类型，邀请类型为2,是宝贝分享邀请
         inviteCode(invite_type);
   }

• 2.生成邀请码，并生成分享链接

分享商品邀请好友]
 * @param  {[type]} invite_type [邀请的类型 2:为宝贝分享邀请]
 * @return {[type]}             [description]
 */
function inviteCode(invite_type) {

$.ajax({

url: '/invite/getInvitedCode',type: 'post',dataType: 'json',success: function(data) {

var iv_text = $('#ivCode').html();

var invite_path = 'http://' + document.domain;

var invite_code = data.data.invite_code;
        var invite_link = invite_path + '/guide_page?ivCode=' + invite_code + 'ivtype=' + invite_type;

        // <a href="https://www.jb51.cc/tag/shengcheng/" target="_blank" class="keywords">生成</a>邀请<a href="https://www.jb51.cc/tag/erweima/" target="_blank" class="keywords">二维码</a>
        //  qrCode(invite_link);
        // <a href="https://www.jb51.cc/tag/fenxiang/" target="_blank" class="keywords">分享</a><a href="https://www.jb51.cc/tag/lianjie/" target="_blank" class="keywords">链接</a>
        sharelink(invite_link);
    }
});
}

• 3.调用微信接口，注册微信分享事件

imgurl = rootPath + '/images/invite_friends/share_240.jpg';
                // 注册微信分享
                initWX(appid,timestamp,signature,lineLink,descContent,shareTitle,imgurl);
        }
    }
});
}

• 4.注册微信分享事件，并注册分享到各个渠道的分享成功回调

imgurl) {
wx.con<a href="https://www.jb51.cc/tag/fig/" target="_blank" class="keywords">fig</a>({
    debug: false,// 开启调试模式,<a href="https://www.jb51.cc/tag/diaoyong/" target="_blank" class="keywords">调用</a>的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印。
