本文概述
我们的“员工”数据库中有两名员工。
假设employee1和employee2:
现在, 打开Fauxton并转到所有文档, 你将在其中看到一个名为New View的块。
单击新视图并填写必填字段:
现在已创建视图。你可以按照以下命令进行验证并查看结果:
创建一个具有以下代码的文件“ app.js”:
const express = require('express');
const bodyParser = require('body-parser');
const path = require('path');
const NodeCouchdb = require('node-couchdb');
const app = express();
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
app.use (bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.get('/', function(req, res){
res.send('Working........');
});
app.listen(3000, function(){
console.log('Server is started om Port 3000');
});
执行以下代码:
node app
打开本地浏览器:localhost:3000
列出数据库
const express = require('express');
const bodyParser = require('body-parser');
const path = require('path');
const NodeCouchdb = require('node-couchdb');
const couch = NodeCouchdb({
auth:{
user: 'ajeet'
password: '12345'
}
});
couch.listDatabases().then(function(dbs){
console.log(dbs);
});
const app = express();
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
app.use (bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.get('/', function(req, res){
res.send('Working........');
});
app.listen(3000, function(){
console.log('Server is started on Port 3000');
});
创建一个文件夹“ view”, 然后在其中创建文件“ index.ejs”, 其中包含以下代码:
Hello World!
现在在“ app.js”文件中进行更改:
res.render('index');
获取查看结果
单击全部, 然后单击API URL复制URL。
现在转到app.js并使用以下内容更改代码:
const express = require('express');
const bodyParser = require('body-parser');
const path = require('path');
const NodeCouchdb = require('node-couchdb');
const couch = new NodeCouchdb({
auth:{
user:"ajeet", password:"12345"
}
});
const dbName ='employees';
const viewUrl = '_design/all_employees/_view/all';
couch.listDatabases().then(function(dbs){
console.log(dbs);
});
const app = express();
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
app.use (bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.get('/', function(req, res){
couch.get(dbName, viewUrl).then(
function(data, headers, status){
console.log(data);
res.render('index', {
customer:data
});
}, function(err){
res.send(err);
});
});
app.listen(3000, function(){
console.log('Server is started on Port 3000');
});
现在启动服务器, 你将看到以下结果:
查看文件详细信息
使用以下代码编辑“ app.js”:
const express = require('express');
const bodyParser = require('body-parser');
const path = require('path');
const NodeCouchdb = require('node-couchdb');
const couch = new NodeCouchdb({
auth:{
user:"ajeet", password:"12345"
}
});
const dbName ='employees';
const viewUrl = '_design/all_employees/_view/all';
couch.listDatabases().then(function(dbs){
console.log(dbs);
});
const app = express();
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
app.use (bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.get('/', function(req, res){
couch.get(dbName, viewUrl).then(
function(data, headers, status){
console.log(data.data.rows);
res.render('index', {
customer:data
});
}, function(err){
res.send(err);
});
});
app.listen(3000, function(){
console.log('Server is started on Port 3000');
});
