chaiHttp忽略端口

我想使用chaiHttp編寫測試nodejs-powered API。下面是我的測試代碼：chaiHttp忽略端口

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(); 
      }); 
    }); 
    }); 
});

server.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;

當我運行測試，我得到的錯誤：

api_1  | NODE_ENV: test 
api_1  | 
api_1  | 
api_1  | Server started on port: 3000 
mongodb_1 | 2017-02-25T13:22:57.693+0000 I NETWORK [thread1] connection accepted from 172.18.0.3:44252 #1 (1 connection now open)

我花了好幾天努力要弄清楚爲什麼chaiHttp請求「127.0.0.1:80」，儘管我明顯在URL中指定端口爲「3000」。

如果我將此行更改爲「chai.request（」http://127.0.0.1:3000「）」更改爲「chai.request（server）」，我會得到相同的結果。

我覺得你的蒙戈網址是錯誤試試這個：'的mongodb：//本地主機：27017/maindb' – cubbuk

「的MongoDB」是主機名由docker-compose分配給MongoDB主機。此外根據日誌數據庫連接是好的。 – Evgeny

然後你可以用「/」開始你的測試路徑：'chai.request（「http://127.0.0.1:3000」）.get（'/ api/products'）'。我已複製並測試您的案例，並且由於缺少'/' – cubbuk

好像你錯過了你的測試請求的領先/：

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