如何使用mysql和knex js（Node js）插入存储在数组中的多条JSON记录？

Question

我有一个代码来存储 id_company、id_variablepoint 和使用 knex js（节点 js）和 mysql 对表“answer”的回答

router.post("/insert_answer", async (req, res, next) => {
  const id_company = req.body.id_company;
  const id_variablepoint = req.body.id_variablepoint;
  const answer = req.body.answer;

  try{
    const tambah = await knex("answer").insert([{id_company:id_company, id_variablepoint:id_variablepoint, answer:answer}])
    res.json({
      "data":tambah
    })
  }catch(e){
    const error = new Error ("ERROR: "+e);
    next(error);
  }
});

我在存储看起来像这样的请求时遇到问题，因为它存储在数组中

[
    {
        "id_company":2,
        "id_variablepoint":57,
        "answer":"choose"
    },
    {
        "id_company":2,
        "id_variablepoint":49,
        "answer":"choose"
    }
]

我的数据库结构如下：

请帮帮我，谢谢

根据 knex doc knex 'insert' 支持数组。所以你不需要担心你的场景。只需将请求传递给 knex insert。

const tambah = await knex("answer").insert(req.body);
