从客户端发送数据到mysql数据库

Question

我正在尝试通过节点 js / expressjs 将表单数据从 react 发送到 mysql 数据库 现在我什么都没有得到没有错误没有数据

这是服务器代码：

app.use(express.urlencoded({ extended: true }));
app.use(express.json());

app.post("/api/insert", (req, res) => {
  const userName = req.body.userName;
  const userDOB = req.body.userDOB;
  const userEmail = req.body.userEmail;
  const userPassword = req.body.userPassword;

  const sqlInsert =
    "INSERT INTO tblUser (strName,dtmDOB,strEmail,strPassword) VALUES (?,?)";
  db.query(
    sqlInsert,
    [userName, userDOB, userEmail, userPassword],
    (err, result) => {
      if (err) throw err;
      console.log("record added");
    }
  );
});

这是我的客户端代码：

const [userName, setUserName] = useState("");
  const [userPassword, setUserPassword] = useState("");
  const [userEmail, setEmail] = useState("");
  const [userDOB, setUserDOB] = useState("");

  const submitForm = () => {
    Axios.post("http://localhost:4000/api/insert", {
      userName: userName,
      userDOB: userDOB,
      userEmail: userEmail,
      userPassword: userPassword,
    }).then(() => {
      alert("success");
    }); 

是 axios 还是 express 的问题？ 知道出了什么问题吗？

Answer 1

请用这个

const sqlInsert = "INSERT INTO tblUser (strName,dtmDOB,strEmail,strPassword) VALUES (?,?,?,?)";

而不是

const sqlInsert = "INSERT INTO tblUser (strName,dtmDOB,strEmail,strPassword) VALUES (?,?)";

db.js：

function query(sql, params, callback) {
  const connection = mysql.createConnection(config.db)
  connection.execute(sql, params, callback);
}

index.js：

app.post("/api/insert", async (req, res) => {
  console.log(req.body)
  const userName = req.body.userName;
  const userDOB = req.body.userDOB;
  const userEmail = req.body.userEmail;
  const userPassword = req.body.userPassword;

  const sqlInsert = "INSERT INTO users (strName,dtmDOB,strEmail,strPassword) VALUES (?,?,?,?)";
  db.query(
    sqlInsert,
    [userName, userDOB, userEmail, userPassword],
    (err, result) => {
      if (err) throw err;
      console.log("record added");
    }
  );
});

结果：

Example app listening at http://localhost:4400
{
  userName: 'aaaabbbb',
  userDOB: 'ddddbbbb',
  userEmail: 'aaaa21@gmail.com',
  userPassword: 'aaaabbbb'      
}
record added
