这里有带MySQL代码的节点js.我能够从这个节点代码将数据传递给MySQL DB.如何继续使用角度到节点js？我来自PHP背景.我应该能够将角度js格式的数据发送到MySQL数据库.我可以从节点代码向MySQL数据库发送数据.

var mysql = require('mysql');

var connection = mysql.createConnection({
  host: 'localhost',
  user: '',
  password: '',
  database: 'copedb'
});
connection.connect();
var cope = {
  author: 'XYZXYZ',
  title: 'Testing Node',
  body: 'Node JS'
};
var query = connection.query('insert into cope set ?', cope, function(err, result) {
  if (err) {
    console.error(err);
    return;
  }
  console.error(result);
});
