我在使用 nodeJS 和 express 时收到错误 404

Question

我在名为 review 的项目中遇到路线问题。我的其他路线没有问题，所以我不确定我哪里出错了。我的前端和邮递员不断收到错误 404。我相信一切都链接到正确的信息。我走路线

http://localhost:8080/api/review/addReview 得到 404 错误

这是我的server.js

const express = require("express");
const cors = require("cors");
const dbConfig = require("./app/config/db.config");

const app = express();

var corsOptions = {
  origin: "http://localhost:8081"
};

app.use(cors(corsOptions));

// parse requests of content-type - application/json
app.use(express.json());

// parse requests of content-type - application/x-www-form-urlencoded
app.use(express.urlencoded({ extended: true }));

const db = require("./app/models");
// const Role = db.role;

app.use('/uploads', express.static('uploads'));

db.mongoose
  .connect(`mongodb+srv://password@cluster0.gmvao.mongodb.net/shop?retryWrites=true&w=majority`, {
    useNewUrlParser: true,
    useUnifiedTopology: true,
    useFindAndModify: false
  })
  .then(() => {
    console.log("Successfully connect to MongoDB.");
    // initial();
  })
  .catch(err => {
    console.error("Connection error", err);
    process.exit();
  });

// routes
// require(".app/routes/favourite.routes")(app);
require("./app/routes/auth.routes")(app);
require("./app/routes/user.routes")(app);

app.use('/api/admin', require('./app/routes/admin.routes'));
app.use('/api/review', require('./app/routes/review.routes'));

// set port, listen for requests
const PORT = 8080;
app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}.`);
});

我的路线文件

const express =  require('express');
const router = express.Router();
const {authJwt} = require("../middlewares");
const Review = require("../models/review.model")

router.use(function(req, res, next) {
      res.header(
        "Access-Control-Allow-Headers",
        "x-access-token, Origin, Content-Type, Accept"
      );
      next();
});


router.post("/addReview", [authJwt.verifyToken], (req, res) => {
    const review = new Review(req.body)

    review.save((err, review) => {
        if(err) return res.json({success:false, err})
        
        Review.find({'_id': review._id})
        .populate('author')
        .exec((err, result) => {
            if(err) return res.json({success: false, err})
            return res.status(200).json({success: true, result})
        })
    })
    
})

module.exports = router ;

我的评论模型文件

const mongoose = require('mongoose');

const Review = mongoose.model(
  "Review",
  new mongoose.Schema({
    prodID: String,
    productTitle: String,
    reviewId: String,
    content: String,
    author: [
      {
        type: mongoose.Schema.Types.ObjectId,
        ref: "User",
      },
    ]
  })
);

module.exports = Review;

Answer 1

一切正常。您的 api/review/addReview 路由方法是 POST，所以请检查您是从 Postman 发出 post 请求。
