javascript - chaiHttp 忽略端口

Question

我正在尝试使用 chaiHttp 为 nodejs 驱动的 API 编写测试。这是我的测试代码:

const mongoose = require("mongoose");
const Products = require('../models/product');

const chai = require('chai');
const chaiHttp = require('chai-http');
const server = require('../server');
const should = chai.should();
const assert = chai.assert;

chai.use(chaiHttp);

describe('Products', () => {
  beforeEach(done => {Products.remove({}, done);});

  describe('/GET products', () => {
    it('it should GET all the products', (done) => {
      //chai.request(server)
      chai.request("http://127.0.0.1:3000")
          .get('api/products')
          .end((err, res) => {
            if (err) {
              assert(false, 'err response: ' + err);
              return;
            }
            res.should.have.status(200);
            res.body.should.be.a('array');
            res.body.length.should.be.eql(0);
            done();
          });
    });
  });
});

服务器.js:

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');

console.log("NODE_ENV: " + process.env.NODE_ENV);

const MONGO_URL = 'mongodb://mongodb:27017/maindb';
const API_PORT = process.env.PORT || '3000';

mongoose.connect(MONGO_URL);
const dbConnection = mongoose.connection;

dbConnection.on('error', err => console.log('connection error:', err.message));
dbConnection.once('open', () => console.log("Connected  to DB!"));

// Express
const app = express();

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

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

// Start server
app.listen(API_PORT, () => {
  console.log("Server started on port: " + API_PORT);
  app.emit('started');
});

module.exports = app;

当我运行测试时，出现错误:

尽管我在 URL 中显然将端口指定为“3000”，但我花了几天时间试图弄清楚为什么 chaiHttp 请求“127.0.0.1:80”。

如果我将行“chai.request("http://127.0.0.1:3000 ")”更改为“chai.request(server)”，这在这里更加一致，我会得到相同的结果。

似乎您错过了测试请求中的前导 /:

chai.request("http://127.0.0.1:3000").get('/api/products') // /api/products instead of api/products
