Quasar Framework Uploader with axios

Question

A question about the quasar framework uploader component. I need to post the images to a URL that will rename the uploaded file and return the full path.

I'm using the upload-factory and axios

But I'm having problems understanding exactly how to pass the file to axios as if it was just an input type file. Basically I need to make it as If I'm sending a form with a single input file like this:

<input type="file" name="banner">

This is the component:

<q-uploader
  url=""
  extensions=".gif,.jpg,.jpeg,.png"
  :filter="filterFiles"
  :upload-factory="uploadFile" />

This is the upload method, but I keep getting an error response from the server.

uploadFile (file, updateProgress) {
  const formData = new FormData()
  formData .set('banner', file)
  var headers = {
    'Content-Type': 'multipart/form-data'
  }
  axios.post('http://someurl/uploadFile', formData , headers)
    .then(function (response) {
      console.log(response)
    })
    .catch(function (response) {
      console.log(response)
    })
}

If I post a plain html form with method="post" enctype="multipart/form-data" and a

<input type="file" name="banner">

I get my OK response from the server with the processed/uploaded image URL

Answer 1

I have successfully done uploading of the file to python API.

V1 Update

Use @added -> function(files) method.

Also extensions property is removed now use accept

This is the component:

<q-uploader
  url=""
  extensions=".gif,.jpg,.jpeg,.png"
  @add="file_selected"
/>

<q-btn @click="uploadFile()">Upload</q-btn>

Data:

data() {
  return {
    selected_file:'',
    check_if_document_upload:false,
  }
}

Methods

file_selected(file) {
  this.selected_file = file[0];
  this.check_if_document_upload=true;
},

uploadFile() {
  let fd = new FormData();
  fd.append("file", this.selected_file);

  axios.post('/uploadFile', fd, {
    headers: { 'Content-Type': undefined },
  }).then(function(response) {
    if(response.data.ok) {
    
    }
  }.bind(this));
}

This is working fine for me.
