使用 ES6 Maps for react-router，我們如何調整 Map.get？

Question

我用new Map()創建了一個地圖來在我的應用程序中存儲我的 RR4 配置。

當我得到/countries/1時，我想訪問/countries/:id的值

routesMap.get('/countries/1') 
// should return the same as to routesMap.get('/countries/:id')

routesMap.get('/countries/1/comments/20'); 
// should match routesMap.get('/countries/:countryId/comments/:id')

通過從Map創建一個類，我如何調整 get 以使其更智能地獲取我的 react-router-dom 路徑？

一個簡單的嘗試將類似於以下內容

 class RouteMap extends Map { get(key) { let match; // exact match if (this.has(key)) return super.get(key); // not exact match, need to apply logic for (let route of this.keys()) { const reg = new RegExp(`^${route.replace(/:\\w+/g,'\\\\w+')}$`); if (!match && reg.test(key)) match = route; } return super.get(match); } } const routesMap = new RouteMap(); routesMap.set('/countries/:id', 'just id') routesMap.set('/countries/:countryId/comments/:id', 'id and country') console.log(routesMap.get('/countries/:id')); console.log(routesMap.get('/countries/1')); console.log(routesMap.get('/countries/:countryId/comments/:id')); console.log(routesMap.get('/countries/1/comments/20'));

但可能需要進一步的工作才能變得更加靈活、高效並處理諸如尾隨 / 等邊緣情況。
