IPFS : Axios responses not properly structured

Questions
1

Hello,
I am working on a dapp and doing my request for infura ipfs api with Axios.
The ‘path’ file argument is required, so I used FormData() to make my path and add multiple files and directories in one request, using form.append() several time.

But the response given to me by infura API is not a correct object.
Do you have any suggestions for the response to be properly structured?
(i can’t use JSON.parse() I have a syntax error)

You can find my request below:

  const form = new FormData();

  for (let i = 0; i < _files.length; i++) {
    form.append(
      "path",
      new Blob(new Int8Array(_files[i].result)),
      _files[i].path
    );
  }

  const res = await axios
    .post("https://ipfs.infura.io:5001/api/v0/add", form, {
      params: {
        "wrap-with-directory": true,
        recursive: true,
      },
      headers: {
        Authorization: auth,
      },
    })
    .catch(function (error) {
      if (error.response) {
        // Request made and server responded
        console.log(error.response.data);
        console.log(error.response.status);
        console.log(error.response.headers);
      } else if (error.request) {
        // The request was made but no response was received
        console.log(error.request);
      } else {
        // Something happened in setting up the request that triggered an Error
        console.log("Error", error.message);
      }
    });

and the response here:

Hi KAM,

Welcome to our forums!

If I’m reading your code right, the output you show is coming from the
console.log(error.response.data);
And that’s what I’d expect to see.

Try outputting the res that get’s returned - this is the actual response - I think you’ll have a better result.

Warm regards,

Hello Chris,

Sorry, it’s my fault, I forgot to put the end of my code, the output comes from “console.log(res.data)”.
I did a lot of research, and the problem may be axios because I found this: https://github.com/axios/axios/issues/3116#issuecomment-842466841

or maybe the way I send multiple files. Anyway, the only way I found to solve this was to put the following code in my axios query.

   transformResponse: [
        function (data) {
          data = JSON.parse("[" + data.split("}\n{").join("},{") + "]");
          return data;
        },
      ]
