gzip解压post请求，axios，Node.JS

Question

I'm doing a post request using axios in node.js. The response is gzip data (behind, it's a huge json)

My goal is to read the json file behind the res (gzip).

Currently, my request is:

await axios({
  method: "post",
  url: process.env.API_URL + "/collection",
  headers: {
    "Content-Type": "application/json",
    "Accept-Encoding": "gzip, deflate, br",
  },
  data: {
    project: req.body.project,
    platform: req.body.platform,
  },
  decompress: true,
}).then(async (response) => {
  console.log(response.data);
});

But I receive data like:

�1�����Q��:GR}��"-��}$K�ևҹ\��°<ܖqw�Vmp������� Y!�����܋a�F�]� ���K%}0� rЈ^�<��/�> ��Q���C7��R>�]§.,j�rg�6�MUVH��_Xq�����}|��a����$����K��cˠ��[�vv�����o�6�v�?~�����h���'Kn.��e��ZUW�;���ŗ��Ӹ׿6j%��M������Էʫ�c1��A�����.�t8�����Ș,����_��C�����۬���?q$޽@�CFq...

Does someone have any suggestion? Thanks !

Answer 1

In my case, I want to get the information of my accessToken (from Google provider), then I can send a GET request like this:

const googleOauth2Url = `https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=${accessToken}`;

const { data } = await axios.get(googleOauth2Url, {
        responseType: "arraybuffer",
        decompress: true,
      });

Then I receive the data that looks similar to yours. I investigate and find out that the data is compressed with gzip , then to use it we must decompress the data .

Now I use zlib.

zlib.gunzip(data, function (error, result) {
        console.log(result.toString());
        return result.toString();
      });

And the final result is:

{
  "issued_to": "some data,
  "audience": "some data",
  "user_id": "some id",
  "scope": "openid https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile",
  "expires_in": 2971,
  "email": "sample@gmail.com",
  "verified_email": true,
  "access_type": "offline"
}
