Added automatic payload serialization to `application/x-www-form-urlencoded` by DigitalBrainJS · Pull Request #4714 · axios/axios

DigitalBrainJS · 2022-05-13T23:14:36Z

Fixed toFormData regression bug (unreleased) with Array-like objects serialization;
Added toURLEncodedForm helper (it's a tiny wrapper around toFormData helper);
Added automatic payload serialization to application/x-www-form-urlencoded to have parity with multipart/form-data;
Added test of handling application/x-www-form-urlencoded body by express.js;
Updated README.md;
Added missed param in JSDoc;
Fixed hrefs in README.md;

const data = {
  x: 1,
  arr: [1, 2, 3],
  arr2: [1, [2], 3],
  users: [{name: 'Peter', surname: 'Griffin'}, {name: 'Thomas', surname: 'Anderson'}],
};

await axios.postForm('https://postman-echo.com/post', data,
  {headers: {'content-type': 'application/x-www-form-urlencoded'}}
);

can be handled by express out of the box:

  var app = express();
  
  // support encoded bodies with extended params signatures
  app.use(bodyParser.urlencoded({ extended: true }));
  
  app.post('/', function (req, res, next) {
     res.send(JSON.stringify(req.body));
  });

  server = app.listen(3000);

After bumping axios to 1.1.0 from 0.27.0 previously working code to upload files using multipart/form-data has broken.

export const FileClient = axios.create({
  baseURL: '/api',
  headers: {
    'Content-type': 'multipart/form-data',
  },
});

...

const formData = new FormData();
formData.append('file', file, file.name);
const result = await FileClient.post<string>(url, formData, {
  headers: {
    Authorization: `Bearer ${token}`,
  },
});

In the outgoing network request I see that axios 1.1.0 is changing the content-type on the request header to application/x-www-form-urlencoded when previously it was multipart/form-data; boundary=---------------------------398240245425200041711494342241

This is causing my backend to try parse the body with a text parser causing HTTP 413 Payload Too Large errors.

Is this expected behavior?

Please update to 1.1.2 and please read the additional docs around multipart form data. There have been numerous changes to make this a lot better.
