Question

历史/背景：显示node.js的html页面

问题陈述：数据库已连接，但当我在本地主机中运行时，它显示'无法获取'。

预期结果：它应该从node.js加载html页面

当前输出：数据库已连接，但无法加载html页面

附加代码：

filter.js

var express = require('express'),
    filter = express(),
    server = require('http').createServer(filter),
    io = require('socket.io').listen(server),
    mongoose = require('mongoose');

server.listen(7550, '127.0.0.1');
console.log('Server running at http://127.0.0.1:7550/');

mongoose.connect('mongodb://localhost/filter_CheckBoxSchema', function (err) {
    if (err) {
        console.log('What happened!!!');
    } else {
        console.log('Connected to mongodb!');
    }
});

var filter_CheckBoxSchema = mongoose.Schema({
    category: { name: String, type: Boolean, default: false },
    created: { type: Date, default: Date.now }
});

var Filter = mongoose.model('Filter', filter_CheckBoxSchema);
filter.get('example.html', function (req, res) {    
    new Filter({
        name: req.body.name,
        type: req.body.gender,

    }).save(function (err, doc) {
        if (err) {
            throw err;
        }
        else
            res.send('Successfully inserted!!!');
    });
});

Answer 1

这里有2个错误：

您应该从root＆＃39; /＆＃39;定义路线。这意味着，如果你想打印＆＃34; hi＆＃34;在127.0.0.1:7550/hi你会写：

app.get（＆＃39; / hi＆＃39;，function（req，res）{ res.send（＆＃39;喜＆＃39）; }）;
要提供静态文件，您应该使用express.static中间件。

app.use（express.static（__ dirname +＆＃39; / public＆＃39;））;
