<code>state: {

        {
            name: 'wang',
            children: []
        }
    ]
},
mutations:{
updateChildren(state,children){
    state.father[0].children = children;
}
},
actions: {
    updateChildren({commit}){
        getChildren(fatherId).then(children => {
            // 获得children，如何更新到father.children中
            commit("updateChildren",children );
        });
