url参数管理器

目的

动态管理url上的参数，可以给url增加参数或减少参数，也可以给某个参数增加或减少属性

举例

API

编号方法使用方法参数使用实例1放入urlmanager.putUrl();  2获取urlmanager.getUrl();  3获取url中的domainmanager.getDomain();  4获取url中的parammanager.getParamOld();  5获取url中的param(进行增加或减少之后)manager.getParam();  6参数进行拆分成mapmanager.getParamMapOld();  7参数进行拆分成map(进行增加或减少之后)manager.getParamMap();  8获取url中某个key的值manager.getOld(k);k：参数manager.getOld("sort");9获取url中某个key的值(进行增加或减少之后)manager.get(k);k：参数manager.get("sort");10获取url中某个参数中某个的值manager.getAttr(attr,k);

attr：参数

k：参数中的键值

manager.getAttr("attr","sort");11往url中加参数manager.add(k,v);

k：参数

v：值

manager.add("attr","price_60-100:200-300");12往url中某个key中放参数manager.addAttr(attr,k,v);

attr：参数

k：键

v：值

manager.addAttr("attr","price","60-100:200-300");13删url中的参数manager.del(k);k：参数manager.del("price");14删url中参数中某个属性manager.delAttr(attr,k);

attr：参数

k：键

manager.delAttr("attr","price");
