我試圖將兩個值 name 和 company 傳遞給服務(wù)器，但它總是將它們作為字符串傳遞。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); }); })name問題出在“VALUES( , company)”行的這一部分數(shù)據(jù)庫 atm 中的結(jié)果： name = name , company = company我需要的結(jié)果是：name = User1，company = Google謝謝你的幫助

根據(jù)您的環(huán)境，您還應該轉(zhuǎn)義查詢值。如果您使用 mysql，您應該可以使用以下內(nèi)容：
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);
});
或不轉(zhuǎn)義：
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);
});

只需停止查詢字符串并在其中包含實際變量：
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);
});
});
