chaiHttp忽略端口
我正在尝试使用chaiHttp编写testingnodejs-powered API。 这是我testing的代码：
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(); }); }); }); }); 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;
当我运行testing时，我得到错误：
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) api_1 | Products mongodb_1 | 2017-02-25T13:22:57.706+0000 I NETWORK [conn1] received client metadata from 172.18.0.3:44252 conn1: { driver: { name: "nodejs", version: "2.2.22" }, os: { type: "Linux", name: "linux", architecture: "x64", version: "4.9.8-moby" }, platform: "Node.js v7.4.0, LE, mongodb-core: 2.1.7" } api_1 | /GET products api_1 | Connected to DB! api_1 | 1) it should GET all the products api_1 | double callback! api_1 | api_1 | api_1 | 0 passing (65ms) api_1 | 1 failing api_1 | api_1 | 1) Products /GET products it should GET all the products: api_1 | Uncaught AssertionError: err response: Error: connect ECONNREFUSED 127.0.0.1:80 api_1 | at chai.request.get.end (test/test-product.js:22:15) api_1 | at Test.Request.callback (node_modules/superagent/lib/node/index.js:615:12) api_1 | at ClientRequest.<anonymous> (node_modules/superagent/lib/node/index.js:567:10) api_1 | at Socket.socketErrorListener (_http_client.js:309:9) api_1 | at emitErrorNT (net.js:1281:8) api_1 | at _combinedTickCallback (internal/process/next_tick.js:74:11) api_1 | at process._tickCallback (internal/process/next_tick.js:98:9)
我已经花了好几天的时间去了解为什么chaiHttp请求“127.0.0.1:80”，尽pipe我明确指定URL中的端口为“3000”。
如果我将“chai.request（” http://127.0.0.1:3000 “）”更改为“chai.request（server）”这个更一致的话，我会得到相同的结果。
看起来像你错过了领先/在你的testing请求：
chai.request("http://127.0.0.1:3000").get('/api/products') // /api/products instead of api/products
