javascript - 如何在nodejs中获取项目的单独id

Question

我有一个删除API，它接受我们要删除的项目的ID，每个项目都有其唯一的ID，我如何获取要删除的项目的ID并将其传递给我的API

这里是API

    app.post("/delete_product", function (req, res) {
            var data = {
                id: req.session.user_id,
                token: req.session.token,
                product_id: 4
    // you need to pass in the id of the product in data.product_id
            };
           functions.callAPIPost(
                "https:/theurl/delete_product",
                data,
                function (error, result) {
                    var response = result;
                    if (response.status === 400) {
                        console.log('ggg',response)
                        res.render('products', {
                            result: result.data
                        })
                    } else {
                        res.redirect('logout')
                    }
                }

            );
        });

这是我的 ejs

<form method='post'  action='/delete_product'>
       <button><iclass="os-icon os-icon-trash" style='font-size: 16px; display: inline-block; vertical-align: middle; margin-right: 10px; color: #8095A0;'></i><span>Delete</span></button>
</form>

我有一个对象数组，在我循环遍历它们后，它们在浏览器中显示为项目，它们都有各自的 id，一旦用户单击调用 api 的项目删除按钮，我如何获取 id删除它。

 [
        {
            "id": 3,
            "name": "work dress",
            "description": "take to work dress",
            "price": "2000",
            "created_at": "2020-02-26T20:30:08.000Z"
        },
        {
            "id": 4,
            "name": "movie dress",
            "description": "take to movie dress",
            "price": "2000",
            "created_at": "2020-02-26T20:30:08.000Z"
        },
        {
            "id": 5,
            "name": "home dress",
            "description": "stay at home dress",
            "price": "2000",
            "created_at": "2020-02-26T20:30:08.000Z"
        }
    ]

您可以通过 POST URL 传递它，并通过 req.params 访问 NodeJS 中的值。

在 EJS 中 -

<form method='post'action='/delete_product/<%= product._id %>?_method=DELETE'>

在 NodeJS 中 -

app.delete("/delete_product/:id", function (req, res) {

    var id_to_delete = req.params.id;

    //rest of the code
});
