javascript - 在nodejs中创建HTTPS api并测试

Question

我正在创建一个应该在 https 上运行的 api。我这样创建服务器:

//...
var app = express();
app.use(passport.initialize());

// do config, like app.use(express.bodyParser());, etc

var myController = require('../app/controllers/myController');  
app.get('/myApi/', myController.someFunction);

var useHTTPS = true;

if (useHTTPS) {
    var https = require('https');
    var fs = require('fs');
    var options = {
      key: fs.readFileSync('./config/key.pem'),
      cert: fs.readFileSync('./config/cert.pem')
    };
    var port = 3443;
    https.createServer(options, app).listen(port);
    console.log('started HTTPS on port ' + port);
} else {
    var port = 3000;
    app.listen(port);
    console.log('started HTTP on port ' + port);
}

module.exports = app;

有了这个，我就可以通过curl访问api了。然后我安装 mocha 和 supertest 并在一个新的 ./test/test.js 文件中尝试这个，该文件是从几个示例复制的......

var assert = require('assert');    
var request = require('supertest')
  , express = require('express');

var app = express();

describe('GET /myApi', function(){
  it('respond with json', function(done){
    request(app)
      .get('/myApi/')
      .expect(200, done);
  })
})

但是这个测试总是失败，永远不会到达我的 Controller 中的 console.log() 。无论我使用 HTTP 还是 HTTPS，它总是这样响应......

1) GET /myApi respond with json: Error: expected 200 "OK", got 404 "Not Found" at Test._assertStatus (node_modules/supertest/lib/test.js:232:12)

我是否错误地创建了 Express https 应用程序？或者我在测试文件中访问它不正确？

我认为在测试文件中简单地说 app = express(); 看起来是错误的，但是当我尝试从 app.js 获取“真正的”应用程序时，就像这样......

// in ./test/test.js
var app = require("../app.js");

我收到另一个错误，指出该端口已在使用中...

Uncaught Error: listen EADDRINUSE :::3443

我认为这是有道理的。我被困住了。任何帮助将不胜感激!

这是一个最小的工作示例:

app.js:

const express = require("express");
const controller = require("./controller");

const useHTTPS = true;
const app = express();
app.get("/api/", controller.someFunction);

let server;
if (useHTTPS) {
  const https = require("https");
  const fs = require("fs");
  const path = require("path");

  const options = {
    key: fs.readFileSync(path.resolve(__dirname, "./config/key.pem")),
    cert: fs.readFileSync(path.resolve(__dirname, "./config/cert.pem")),
  };
  const port = 3443;
  server = https.createServer(options, app);
  server.listen(port);
  console.log("started HTTPS on port " + port);
} else {
  const port = 3000;
  server = app.listen(port);
  console.log("started HTTP on port " + port);
}

module.exports = server;

controller.js:

function someFunction(req, res) {
  res.sendStatus(200);
}

module.exports = {
  someFunction,
};

app.test.js:

const request = require("supertest");
const app = require("./app");

describe("GET /api", function() {
  after((done) => {
    app.close(done);
  });
  it("respond with json", function(done) {
    request(app)
      .get("/api/")
      .expect(200, done);
  });
});

集成测试结果与覆盖率报告:

started HTTPS on port 3443


  GET /api
    ✓ respond with json

错误Uncaught Error: Listen EADDRINUSE:::3443 表示该地址已在使用中。
