我对Node还不太熟悉。js和我对连接本地主机和与MongoDB的接口感到有些困惑。似乎它忽略了我创建的路线。
首先,这里是我的目录结构的快照。
这是我的包裹。json:
{
"name": "summer_breeze",
"version": "1.0.0",
"devDependencies": {
"grunt": "~0.4.1",
"grunt-contrib-concat": "^1.0.1",
"grunt-contrib-imagemin": "^1.0.1",
"grunt-contrib-sass": "^1.0.0",
"grunt-contrib-uglify": "^2.3.0",
"grunt-contrib-watch": "^1.0.0",
"webpack-dev-server": "^2.9.7"
},
"description": "",
"main": "app.js",
"scripts": {
"start": "nodemon ./start.js"
},
"author": "*** ********",
"license": "ISC",
"dependencies": {
"cookie-parser": "^1.4.3",
"dotenv": "^4.0.0",
"express": "^4.16.2",
"mongod": "^2.0.0",
"mongoose": "^4.13.7",
"nodemon": "^1.14.1",
"normalize.css": "^6.0.0"
}
}
这是我的开始。js文件:
const mongoose = require('mongoose');
// import environmental variables from our variables.env file
require('dotenv').config({ path: 'variables.env' });
mongoose.connect(process.env.DATABASE, { useMongoClient: true });
mongoose.Promise = global.Promise;
mongoose.connection.on('error', (err) => {
console.error(`${err.message}`);
});
const app = require('./app');
app.set('port', process.env.PORT || 7777);
const server = app.listen(app.get('port'), () => {
console.log(`Express running â PORT ${server.address().port}`);
});
这是我的应用程序。js公司:
const express = require('express');
const path = require('path');
const cookieParser = require('cookie-parser');
const bodyParser = require('body-parser');
const routes = require('./routes/index');
const errorHandlers = require('./handlers/errorHandlers');
const app = express();
app.use(express.static(path.join(__dirname, 'public')));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use('/', routes);
// If that above routes didnt work, we 404 them and forward to error handler
app.use(errorHandlers.notFound);
// One of our error handlers will see if these errors are just validation errors
app.use(errorHandlers.flashValidationErrors);
// Otherwise this was a really bad error we didn't expect! Shoot eh
if (app.get('env') === 'development') {
/* Development Error Handler - Prints stack trace */
app.use(errorHandlers.developmentErrors);
}
// production error handler
app.use(errorHandlers.productionErrors);
module.exports = app;
这是索引。js文件我必须处理所有路由:
const express = require('express');
const router = express.Router();
router.get('/', (req, res) => {
res.send('Hello World!');
});
module.exports = router;
当我跑步时
npm start
在命令行上,我得到的是:
> summer_breeze@1.0.0 start /Users/**********/Repos/Summer_Breeze
> nodemon ./start.js
[nodemon] 1.14.1
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `node ./start.js`
Express running â PORT 7777
这很好。这是我所期待的。但当我在web浏览器中转到localhost:7777时,它会调出我的索引。公共文件夹中的html页面,当我在开发工具中打开控制台时,什么都没有。这就好像完全忽略了我创建的路线。
为什么会这样?我唯一的路径应该是控制台日志“Hello World!”。我以为我得跑了
router.get('/', (req, res) => {
res.sendFile('public/index.html');
});
让它加载我的索引。html文件。
为什么它会拉我的索引。html文件?如果在查找索引时出现问题,是否有一个默认路由为静态文件提供服务。js文件?我甚至尝试从索引中删除所有路由。js文件,它似乎仍在加载我的索引。html文件。
有谁能让我更深入地了解一下正在发生的事情吗?非常感谢!
