如何將所有這些一起使用?例如,我有一個帶有一個表(ID,文本,完成)的簡單數據庫和一個將數據從mySQL導出到JSON文件的代碼。 JSON文件看起來像:angular + node(express)+ mysql
[{ "id":"1", "text":"learn angular", "done":true },
{ "id":"2", "text":"build an angular app", "done":false}]
而且server.js文件:
var fs = require('fs');
var serverUrl = 'localhost';
var port = 3000;
var path = require('path');
var express = require('express');
var app = express();
var http = require('http').Server(app);
var mysql = require('mysql');
var bodyParser = require('body-parser');
var methodOverride = require('method-override');
app.use(bodyParser.json()); // parse application/json
app.use(bodyParser.json({ type: 'application/vnd.api+json' }));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(methodOverride('X-HTTP-Method-Override'));
app.use(express.static(__dirname + '/public'));
require('./app/routes')(app); // pass our application into our routes
app.get('/', function(req, res){
res.sendfile('public/index.html');
});
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '',
database : 'todos',
});
connection.connect();
app.get('/',function(request,response){
connection.query('SELECT * FROM todos', function(err, rows, fields, res)
{
console.log('Connection result error '+err);
console.log('no of records is '+rows.length);
response.writeHead(200, { 'Content-Type': 'application/json'});
response.end(JSON.stringify(rows));
});
app.set('port', 3000);
http.listen(port, function(){
console.log('listening on: ' + app.get('port'));
});
exports = module.exports = app;
我應該怎麼做?我如何使用從angularjs應用程序從mysql導出到JSON數據? index.html文件:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<base href="/">
<title></title>
<!-- CSS -->
<!-- JS -->
<!-- ANGULAR CUSTOM -->
</head>
<body ng-app="App" ng-controller="Controller">
<div class="someClass">
<table>
<tr>
<th>id</th>
<th>text</th>
<th>done</th>
</tr>
<tr ng-repeat="todo in todos">
<td>{{todo.id}}</td>
<td>{{todo.text}}</td>
<td>{{todo.done}}</td>
</tr>
</table>
<div>
</body>
</html>
我理解正確的整個機制嗎?我們在mysql中有一些數據庫,將mysql數據轉換成json對象,然後用角度讀取這些對象?如果是這樣,那麼我們如何才能用數據庫執行crud操作?預先感謝任何意見和答案,這將有助於我理解它。
爲獲取數據到您的角度應用程序您需要使用角度$ HTTP服務進行ajax調用請閱讀此處:https://docs.angularjs.org/api/ng/service/$http – happyZZR1400
