1.安装node.js (https://www.baidu.com/link?url=Zc5ZhRCz3mtjk2Vep48iK_fxhnqCquTpeWWI8WVxX-W&wd=&eqid=b67924fd00087041000000065e0db1c4)
2.初始化，并安装依赖包 npm init && npm install
3创建文件例：app.js
var mysql = require('mysql');
var http = require('http');
var connection = mysql.createConnection({
host: '192.168.0.43',
user: 'root',
port: '30030',
password: 'AbcXyz123',
database: 'cpqueuedb'
});
connection.connect();
var sql = 'SELECT * FROM queueyyinfo';
//查
connection.query(sql, function(err, result) {
if (err) {
console.log('[SELECT ERROR] - ', err.message);
return;
}
http.createServer(function(request, response) {
response.writeHead(200, {
"Content-Type": 'text/plain',
'charset': 'utf-8',
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'PUT,POST,GET,DELETE,OPTIONS'
});
response.end(JSON.stringify(result))
}).listen(3030)
connection.end();
});
console.log("http://127.0.0.1:3030/");然后运行 node app.js
然后创建html 利用ajax来调用测试。这里偷个懒使用了jq
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
</body>
</html>
<script src="https://cdn.bootcss.com/jquery/1.11.2/jquery.js"></script>
<script>
$.ajax({
url: 'http://127.0.0.1:3030/',
type: 'get',
success: function(data) {
console.log(JSON.parse(data))
},
error: function(err) {
console.log(err)
}
})
</script>
