Node.js,Express.js - 意外令牌{

Question

我的应用程序每次到达此行时都会崩溃:

const {name, price} = req.query;
        ^

似乎无法找到确切的答案..错误日志

SyntaxError: Unexpected token {
    at exports.runInThisContext (vm.js:53:16)
    at Module._compile (module.js:373:25)
    at Object.Module._extensions..js (module.js:416:10)

    at Function.Module.runMain (module.js:441:10)

背景:

app.get('/products/add' , (req, res) => {
  const {name, price} = req.query;

  const INSERT_PRODUCTS_QUERY = `INSERT INTO products (name, price) VALUES ('${ name }', ${ price })`;
  connection.query(INSERT_PRODUCTS_QUERY, (err,results) => {
      if(err)
      {
        return res.send(err);
      }
      else
      {
        return res.send('succesfully added product');
      }
  });
});

根据node.green,使用primitives语法的对象解构在Node.JS v6.4.0之后工作,并抛出Unexpected Token {下面的Node.js版本.

此外,对象rest/spread属性仅在Node v8.6.0中开箱即用.它在带有--harmony标志的v8.2.1中工作,并抛出Unexpected Token ...下面的Node.js版本.
