Question

已更新：因为我知道错误与我的代码无关。

大家好！

我注释了所有与express-rate-limit相关的代码，但是此程序包仍然有错误。

我的代码：

const express = require('express');
const router = express.Router();
// const RateLimit = require('express-rate-limit');
const cors = require('cors')

// const apiLimiter = new RateLimit({
//     windowMs: 1000 * 60 * 5,
//     max: 5,
//     // message : "درخواست شما زیاد بوده لطفا 15 دقیقه دیگر دوباره تلاش کنید"
//     handler: function (req, res, /*next*/) {
//         res.json({
//             data: 'درخواست شما زیاد بوده لطفا 15 دقیقه دیگر دوباره تلاش کنید',
//             status: 'error'
//         })
//     }
// });

let prefixes = ["v1"];
for (let prefix of prefixes) {
    router.use(`/${prefix}/`, require(`./${prefix}/home`));
    router.use(`/${prefix}/auth`, cors(), require(`./${prefix}/auth`));
    router.use(`/${prefix}/admin`, cors(), require(`./${prefix}/admin`));

    // router.use(`/${prefix}/`, cors(), apiLimiter, require(`./${prefix}/home`));
    // router.use(`/${prefix}/auth`, cors(), apiLimiter, require(`./${prefix}/auth`));
    // router.use(`/${prefix}/admin`, cors(), apiLimiter, require(`./${prefix}/admin`));
}

module.exports = router;

错误文本为：

请帮帮我！我该怎么办？

Answer 1

我认为您应该像这样使用它

router.use(`/${prefix}/`, cors(), apiLimiter, require(`./${prefix}/home`));

Answer 2

如果检查apiLimiter的类型，则会得到'object'。除非typeof apiLimiter是一个“函数”，否则您不能调用apiLimiter（）。

大卫的解决方案应该可以解决问题

TypeError：无法读取未定义的属性“ ip”-express-rate-limit
