PHP post 通过动态传递值请求

Question

我试图将名称和公司这两个值传递给服务器，但它总是将它们作为字符串传递。

app.post('/visitors/store', (req, res) => {
const name = req.body.name; (User1)
const company = req.body.company; (Google)
con.query("INSERT INTO visitors(name, company) VALUES(`name`,`company`)", (results) => {
            res.json(results);
        });
  })

问题出在行的这一部分 "VALUES(name,company)"

数据库atm中的结果：name = name , company = company

我需要的结果是：name = User1，company = Google

感谢您的帮助

Answer 1

只需中断查询字符串并在其中包含实际变量：

app.post('/visitors/store', (req, res) => {
    const name = req.body.name;
    const company = req.body.company;
    con.query("INSERT INTO visitors(name, company) VALUES('" + name + "','" + company + "')", (results) => {
        res.json(results);
    });
});

Answer 2

根据您的环境，您还应该转义查询值。如果你使用 mysql 你应该可以这样：

app.post('/visitors/store', (req, res) => {
const name = req.body.name;
const company = req.body.company;
con.query("INSERT INTO visitors(name, company) VALUES(?,?)", [name, company], (results) => {
    res.json(results);
});

或不转义：

app.post('/visitors/store', (req, res) => {
const name = req.body.name;
const company = req.body.company;
con.query(`INSERT INTO visitors(name, company) VALUES(${name}, ${company})`, (results) => {
    res.json(results);
});
