有条件地在 GET 请求中使用中间件

Question

我正在使用快速路由。 这是我的要求

import { Router, Request, Response, NextFunction } from "express";
import { celebrate, Joi, Segments } from "celebrate";
const route = Router();
export default (app: Router) => {
route.get("/:id",
celebrate({
[Segments.PARAMS]: Joi.object({
id: Joi.string().required().label("Store Id")
})
}),
basicAuth, //a middleware
asyncHandler(async (req: Request, res: Response, next: NextFunction) => {
// some operations.
return res.status(202).json(storeDetails);
})
);
}

在这里，我如何有条件地使用basicAuth中间件，以便在id=="me"时使用basicAuth，否则使用另一个中间件isAuth。

Answer 1

如果满足条件，您可以手动调用中间件：

route.get("/:id",
celebrate({
[Segments.PARAMS]: Joi.object({
id: Joi.string().required().label("Store Id")
})
}),
asyncHandler(async (req: Request, res: Response, next: NextFunction) => {
if (req.params.id === "me") {
// call basicAuth middleware manually
basicAuth(req, res, err => {
if (err) {
// send error response here
next(err);
} else {
// continue processing here now that basicAuth has been verified
}
});

} else {
// not "me"
// some operations.
return res.status(202).json(storeDetails);
}
})
);
}
