SAAS云平台搭建札记: (三) AntDesign + .Net Core WebAPI权限控制、动态菜单的生成
thanks 人气:0我们知道，当下最火的前端框架，非蚂蚁金服的AntDesign莫属，这个框架不仅在国内非常有名，在国外GitHub上React前端框架也排名第一。而且这个框架涵盖了React、Vue、Angular等多种语言，甚至有人结合.net Core 5的新特性WebAssembly做了Ant Design Blazor，在此为国人点赞！
公司的新平台，用户前端界面当仁不让地使用了AntDesign for React，可以使用最新版本的特性（目前版本为4.10.1）；至于为什么不使用Ant Design Pro，是因为Pro封装的控件太多，不利于我们自定义页面。
SAAS系统，页面上首先就是权限，我们后台采用中等复杂度的RBAC控制，如图所示：
在界面上表示，就是程序左侧的树状菜单，参照AntdPro的官方文档，路由和菜单，需要在菜单的ts文档中写清楚各种权限组和相应菜单，显然不符合我们前后端分离使用动态菜单的方法。
因此，我研究一段时间，终于找到完全在后端生成动态菜单并且在前端的使用方法，特此分享给大家。
传递到前端的菜单实体类：
1 public class 菜单实体类
2 {
3 public string key { get; set; }
4 public string icon { get; set; }
5 public string title { get; set; }
6 public string link { get; set; }
7 public IEnumerable<PortalMenu> children { get; set; }
8 }
实际上是一个递归结构的json字符串：
1 {
2 "returnCode": 0,
3 "errorMsg": null,
4 "data": {
5 "portalMenus": [{

前端页面接收后，处理下一二三级菜单，加上图标，就可以渲染出来了：
1 ......
2
3 state = {
4 collapsed: false,
5 openKeys: [],
6 menus: null,
7 defaultMenuId: null,
8 };
9
10 async componentDidMount() {
11 var menus = await getUserMenus();
12 var allMenus = await this.getSubMenus(menus.portalMenus);
13 this.setState({ menus: allMenus, defaultMenuId: menus.defaultMenuId });
14 }
15
16 getSubMenus = (children) =>{
17 let menuInfo = [];
18 children.forEach(ele=>{
19 if (ele.children && ele.children.length > 0) {
20 menuInfo.push(<SubMenu key={ele.key} title={ele.title} icon={GetIconByName(ele.icon)}>{this.getSubMenus(ele.children)}</SubMenu>);
21 } else {
22 menuInfo.push(<Menu.Item key={ele.key} icon={GetIconByName(ele.icon)}><Link to={ele.link}>{ele.title}</Link></Menu.Item>);
23 }
24 });
25 return menuInfo;
26 };
27
28 render() {
29 return (
30 <Router>
31 <Layout>
32 <Sider trigger={null} collapsible collapsed={this.state.collapsed}>
33 <div className="logo">
34 .
35 </div>
36 <Menu theme="dark" mode="inline"
37 defaultSelectedKeys = {[this.state.defaultMenuId]}
38 openKeys={this.state.openKeys}
39 onOpenChange={this.onOpenChange}>
40 {this.state.menus}
41 </Menu>
42 </Sider>
43 ......
至此，左边的菜单就按照每个人的不同权限渲染出来了。
附：前端的getUserMenus和Comm方法：
1 //用户取菜单
2 async function getUserMenus() {
3 var result = await Comm(....);
4 return result.data;
5 }
6
7 async function Comm(code, ...){
8 var body = {};
9 body.Code = code;
10 body.data = ...;
11
12 var cookie = getCookie(global.......);
13 var headers = {};
14 headers["Content-Type"] = 'application/json';
15 if(cookie){
16 headers.token = cookie;
17 }
18
19 const response = await fetch(global.webApiUrl,{
20 method: 'POST',
21 body: JSON.stringify(body),
22 headers: new Headers(headers)
23 });
24 const rep = await response.json();
25 return rep;
26 }
