[javascript] How do I set multipart in axios with react?

When I curl something, it works fine:

curl -L -i -H 'x-device-id: abc' -F "url=http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"  http://example.com/upload

How do I get this to work right with axios? I'm using react if that matters:

uploadURL (url) {
  return axios.post({
    url: 'http://example.com/upload',
    data: {
      url: url
    },
    headers: {
      'x-device-id': 'stuff',
      'Content-Type': 'multipart/form-data'
    }
  })
  .then((response) => response.data)
}

This doesn't work for some reason.

ok. I tried the above two ways but it didnt work for me. After trial and error i came to know that actually the file was not getting saved in 'this.state.file' variable.

fileUpload = (e) => {
    let data = e.target.files
    if(e.target.files[0]!=null){
        this.props.UserAction.fileUpload(data[0], this.fallBackMethod)
    }
}

here fileUpload is a different js file which accepts two params like this

export default (file , callback) => {
const formData = new FormData();
formData.append('fileUpload', file);

return dispatch => {
    axios.put(BaseUrl.RestUrl + "ur/url", formData)
        .then(response => {
            callback(response.data);
        }).catch(error => {
         console.log("*****  "+error)
    });
}

}

don't forget to bind method in the constructor. Let me know if you need more help in this.

If you are sending alphanumeric data try changing

'Content-Type': 'multipart/form-data'

to

'Content-Type': 'application/x-www-form-urlencoded'

If you are sending non-alphanumeric data try to remove 'Content-Type' at all.

If it still does not work, consider trying request-promise (at least to test whether it is really axios problem or not)
