Cookie写入之path的坑不同目录下值不同

### 解释：   path = / 表示主目录下的所有文件都有权限访问到cookie的值，   但是若是没有定义则表示是一种继承关系，就是若是访问了product/select的话 那么就是写入cookie路径在product里，只有它的子路径可以获取到改cookie，而主页面没办法获取到product的cookie ###

如果  window.document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString() + "; path=/";  这种的话  就是

如果  window.document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString() \+ "/";
