[英]How to get GET params from express with typescript in node.js?
我正在使用 node.js + express + typescript,我想獲得 GET 參數。 到目前為止我有這個
app.get('/top_games', (req, res) => {
const page = req.route.page;
const offset = req.route.offset;
const game_data = DAO_GAME.GetTopGuilds(100, 0);
res.send({
total : game_data[0],
data : game_data[1]
});
});
但 eslint 抱怨
const page = req.route.page;
const offset = req.route.offset;
說
Unsafe assignment of an any value.eslint@typescript-eslint/no-unsafe-assignment
Unsafe member access .page on an any value.eslint@typescript-eslint/no-unsafe-member-access
我怎樣才能解決這個問題?
修好了,我必須做
const page = parseInt(req.query.page as string, 10);
const page_size = parseInt(req.query.page_size as string, 10);
從@types/express@4.17.2
開始, Request
類型使用 generics 。 我們可以使用它自己輸入解析的查詢參數:
import { Request } from 'express';
type QueryParams = {
page: string;
page_size: string;
};
app.get('/top_games', (req: Request<{}, {}, {}, QueryParams>, res) => {
const page = parseInt(req.route.page, 10);
const offset = parseInt(req.route.offset, 10);
// ...
});
