Question

我正在尝试使用从GET请求接收的数据填充数据库。每个请求返回500个项目，这又向数据库发出500个POST。共有686个GET请求。我遇到的问题是在第三个GET之后，我开始接收Error: connect EMFILE并最终在数据库中只有〜1700个项目。

我如何顺序/同步进行这些API调用以避免这种情况？

function getProducts(myUrl) {
    axios.get(myUrl, { httpsAgent: agent })
        .then(res => {
            res.data.products.forEach(product => {
                var product = {
                    'values': {
                        '2': product.name,
                        '3': product.display_price,
                        '4': product.slug
                    }
                };
                postProduct(product);
            });
        })
        .catch(err => {
            console.log(err);
        });
}

function postProduct(product) {
    axios.post(huburl, product)
    .then(res => {
        console.log(res.data);
    })
    .catch(err => {
        console.log(err)
    });
}

for (let i = 1; i <= 686; i++) {
    var pagedUrl = url + '&page=' + i;
    console.log(pagedUrl);
    getProducts(pagedUrl);
}

这是对异步/等待的简单转换，我说过我会在评论中发布。
