Javascript Node.js TypeError:JSON.parseInt不是函数

我对Node.js有问题。 我已经安装了nodemoden和express。 我的标题有个错误。谁能看看我的密码吗？ 我有1个index.js文件和3个json文件。 另外，我有6个js文件，下面的1个是finds.js。其他5个文件是cheapmealsroute.js。largemealsroute.js等等

index.js

const express = require('express');
const app = express();
const port = 3001;

const meals = require('./data/meals.json');
const reservations = require('./data/reservations.json');
const reviews = require('./data/reviews.json');

const mealsRouter = require('./routes/mealsroute');
const cheapMealsRouter = require('./routes/cheapmealsroute');
const largeMealsRouter = require('./routes/largemealsroute');
const randomMealRouter = require('./routes/mealroute');
const reservationsRouter = require('./routes/reservationsroute');
const reservationRouter = require('./routes/reservationroute');


app.use('/meals', mealsRouter);

app.use('/cheap-meals', cheapMealsRouter);

app.use('/large-meals', largeMealsRouter);

app.use('/random-meals', randomMealRouter);

app.use('/reservations', reservationsRouter);

app.use('/reservation', reservationRouter);

app.listen(
  port,
  () => console.log(`Example app listening at http://localhost:${port}`)
);

mealsroute.js

const express = require('express');
const router = express.Router();

const fs = require('fs');
const meals = JSON.parseInt(fs.readFileSync(__dirname + '/../data/meals.json'));

router.get('/', (request, response) =>
  response.send(meals)

);

module.exports = router;

feeds.json

问题是JSON.parseInt不是一个函数

我不知道你从哪里得到的JSON有一个parseInt函数

首先解析JSON以将JSON用作JS对象（JSON.parse（））

---

然后使用.parseInt（）解析所需的整数

将

JSON.parseInt

替换为

JSON.parse

如果要将某些JSON转换为JavaScript对象，可以使用JSON.parse（myJson）

如果要将整数的字符串表示形式转换为数字类型，可以使用parseInt（myStr）

---

我想你可能只是混淆了两者。

我想你的意思是

JSON.parse

，而不是

parseInt

。正如错误所说，

JSON.parseInt

不是函数。也许你的意思是

JSON.parse

@AlexBroadwin

parseInt

在那一餐上。JSON文件将产生

NaN

非常感谢。没问题，祝你过得愉快：）非常感谢。非常感谢。
