Files Uploading

In order to upload a file, you should get an access token which will be used in the subsequent requests.

Suppose we have the following form for the file input:

<form id="fileForm">
  <h2>Select a file:</h2>
  <input type="file" name="file" id="fileUpload"/>
  <br/>
  <button type="submit">Upload</button>
</form>

<h2>Result:</h2>

<img id="uploadedFile" src="" style="display: none"/>

We will use jQuery for the upload and get a JSON with data which is the newly created FileDescriptor instance. We can access the uploaded file by its FileDescriptor id with the access token as a parameter:

$('#fileForm').submit(function (e) {
    e.preventDefault();

    var file = $('#fileUpload')[0].files[0];
    var url = 'http://localhost:8080/app/rest/v2/files?name=' + file.name; // send file name as parameter

    $.ajax({
        type: 'POST',
        url: url,
        headers: {
            'Authorization': 'Bearer ' + oauthToken // add header with access token
        },
        processData: false,
        contentType: false,
        dataType: 'json',
        data: file,
        success: function (data) {
            alert('Upload successful');

            $('#uploadedFile').attr('src',
                'http://localhost:8080/app/rest/v2/files/' + data.id + '?access_token=' + oauthToken); // update image url
            $('#uploadedFile').show();
        }
    });
});
