参数转对象 类似 ?camera=1&travel=0&faceScore=1

parseQueryString(url) {
            var obj = {};
            var keyvalue = [];
            var key = "", value = "";
            var paraString = url.substring(url.indexOf("?") + 1, url.length).split("&");
            for (var i in paraString) {
                keyvalue = paraString[i].split("=");
                key = keyvalue[0];
                value = keyvalue[1];
                obj[key] = value;
            }
            return obj;
        },
