抓取qq的代码 可能 需要用到的 转换 img的src代码

    (function($){
        function changeData(data, tag){
            for(var i = 0; i < data.length; i++){
                if(!data[i].hasAttribute("data-src") && data[i].hasAttribute("src") && (data[i].getAttribute("src")).lastIndexOf('http://', 0) === 0 && (data[i].getAttribute("src")).indexOf('weixinduba.com/') == -1){
                    data[i].setAttribute("data-src", data[i].getAttribute("src"));
                }
                if(data[i].hasAttribute("data-src")){
                    datasrc = data[i].getAttribute("data-src");
                    datasrc = datasrc.replace("https://v.qq.com/", 'http://v.qq.com/')
                    data[i].setAttribute("src", (tag == 'image' && datasrc.indexOf('http://read.html5.qq.com/image') == -1) ? "http://www.weixinduba.com/a.php?img=" + datasrc : datasrc);
                    data[i].removeAttribute("data-src");
                }
            }
        }
        var imgs = document.getElementsByTagName('img');
        var videos = document.getElementsByClassName('video_iframe');
        changeData(imgs, 'image');
        changeData(videos, 'video');

        /*$('#page-content img').each(function(index, el) {
         $(el).attr({src:'https://'+window.location.host+'/Home/Index/images?url='+$(el).data('src')+''});

         $(el).attr('data-src',null);
         });*/
        var doc = document;

        var title = doc.getElementsByTagName('title')[0].innerHTML;

        var head = doc.getElementsByTagName('head')[0];
        var meta = doc.createElement('meta');
        meta.name = 'description';

        meta.content = title;
        head.appendChild(meta);

        var url = window.location;
        $.urlName = function(name){
            var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)"),
                    r   = url.search.substr(1).match(reg);
            return r == null ? null : r;
        };
        $.urlRemove = function(name){
            var r = $.urlName(name);
            return r == null ? null : url.href.replace(r[0],'');
        }
    })(jQuery);
</script>

只需要用上面的代码就行
