【问题描述】：

在我的 index.js 文件中

app.delete("/delete/:nurseid", (req, res) => {
    const nurseID = req.params.nurseID
    console.log(nurseID); // undefined
    connection.query('DELETE FROM nurse WHERE nurseID = ?', nurseID , (err, result) => {
        if(err) {
            console.log(err);
        }
        else {
            res.send(result);
        }
    });
});

反应 app.js

      const deleteNurse = (nurseID) => {
        console.log(nurseID);

        Axios.delete(`http://localhost:4000/delete/${nurseID}`, { 
          data: { nurseID: nurseID}
        });
      }

发送此请求后，后端返回req.params.nurseID未定义。

应该是nurseid 而不是nurseID。你现在可能已经注意到了。
