Uploaded Files are Currupt (Flask, Python)

Uploaded Files are Currupt (Flask, Python)

Explorer | Level 3

Hey, guys so I'm experimenting with the Dropbox python API using Flask. I managed to upload files but all the files I've uploaded are only 16 bytes in size and are unable to be opened. here's the code I'm using. 

 

HTML Form:

 

<div style="text-align: center" class="form">
          <form class="needs-validation" novalidate action="/uploadtest" method="POST" enctype="multipart/form-data">
            <div class="col-md-12">
              <div class="form-group">
                <label for="name">Choose file</label>
                <input type="file" accept=".xlsx, .jpg" name="file" id="fileToUpload" class="form-control" placeholder="John Smith"
                  required>
                <div class="valid-feedback">
                  Looks good!
                </div>
                <div class="invalid-feedback">
                  Please choose a .xlsx file.
                </div>
              </div>
            </div>
            <button type="submit" class="btn btn-success" value="">Submit</button>
          </form>
        </div>

 

 

Python Flask Route 

@app.route('/uploadtest', methods=['POST', 'GET'])
def get_dropbox_files():
    if request.method == 'POST':
        uploadedfile = request.files['file']
        client = dbx_client
        f = secure_filename(uploadedfile.filename)
        path="/nameinlights/" + f
        dbx_client.files_upload(f.encode(), path)
        flash("Added" + " " + f + " " + "to Name in Lights Folder", 'success')

            
    return render_template('uploadtest.html', file_list=file_list)

Re: Uploaded Files are Currupt (Flask, Python)

Hi!

 

When you call file_upload, you're actually uploading the file's name as a string. Each file is coming out to 16 bytes because the strings are being generated by secure_filename and are probably a standard length.

 

You can fix it by changing the first variable you're passing to file_upload.

        dbx_client.files_upload(f.encode(), path)

should be

        dbx_client.files_upload(uploadedfile.encode(), path)

It looks like you're just working with the filename
