请求失败，状态码为 429 Axios

Question

I am trying to parse lots of data from external API endpoint to my Database, I keep getting error 429.

I've tried timeout and sleep lib but it doesn't work for some reason.

Here is the code:

async function(req, res) {
    console.log("usa sam");
    try {
        let count = await Subjekti.estimatedDocumentCount();
        let response = await axios.get(`x.com/?offset=${count}&limit=5000`, {
            timeout: 5800,
            headers: {
                "Key": "x"
            }
        });
        const subjects = response.data;
        for (let subject of subjects) {
            let companyDetails = await axios.get(`https://x.com=${subject.mbs}&expand_relations=true`, {
                headers: {
                    "Key": "x"
                }
            });
            await Subjekti({
                mbs: subject.mbs,
                sud_id_nadlezan: subject.sud_id_nadlezan,
                sud_id_sluzba: subject.sud_id_sluzba,
                oib: subject.oib,
                ino_podruznica: subject.ino_podruznica,
                stecajna_masa: subject.stecajna_masa,
                datum_osnivanja: subject.datum_osnivanja,
                postupak: subject.postupak,
                likvidacijska_masa: subject.likvidacijska_masa,
                skracene_tvrtke: companyDetails.data.skracene_tvrtke && companyDetails.data.skracene_tvrtke.length > 0 ? companyDetails.data.skracene_tvrtke[0].ime : null,
                ulica: companyDetails.data.sjedista && companyDetails.data.sjedista.length > 0 ? companyDetails.data.sjedista[0].ulica : null,
                kucni_broj: companyDetails.data.sjedista && companyDetails.data.sjedista.length > 0 ? companyDetails.data.sjedista[0].kucni_broj : null,
                naziv_naselja: companyDetails.data.sjedista && companyDetails.data.sjedista.length > 0 ? companyDetails.data.sjedista[0].naziv_naselja : null,
                naziv_zupanije: companyDetails.data.sjedista && companyDetails.data.sjedista.length > 0 ? companyDetails.data.sjedista[0].naziv_zupanije : null,
            }).save();
            console.log("spremija i cekam");

        }
    } catch (err) {
        //Baci error 500...
        return apiResponse.ErrorResponse(res, err);
    }
}

Looking forward to your reply.

Answer 1

You are sending too many requests, and you get ratelimited.

You should change your logic to allow more data to be sent and retrieved with a single request, or delaying most part of your requests to a later stage.

To delay request using axios interceptors, take a look here:

Ive found out solution:

await new Promise(resolve => setTimeout(resolve, 5000));

Hope it helps someone and save you time.

Answer 3

Try using debounce approach in this case to avoid sending too many requests.
