使用 Flask 上传多个文件 [英] Uploading multiple files with Flask

问题描述

有没有办法用 Flask 接收多个上传的文件?我尝试了以下方法:

Is there a way to receive multiple uploaded files with Flask? I've tried the following:

<form method="POST" enctype="multipart/form-data" action="/upload">
  <input type="file" name="file[]" multiple="">
  <input type="submit" value="add">
</form>

然后打印request.files['file']的内容:

@app.route('/upload', methods=['POST'])
def upload():
  if not _upload_dir:
    raise ValueError('Uploads are disabled.')

  uploaded_file = flask.request.files['file']
  print uploaded_file
  media.add_for_upload(uploaded_file, _upload_dir)
  return flask.redirect(flask.url_for('_main'))

如果我上传多个文件，它只打印集合中的第一个文件:

If I upload multiple files, it only prints the first file in the set:

<FileStorage: u'test_file.mp3' ('audio/mp3')>  

有没有办法使用 Flask 的内置上传处理来接收多个文件?感谢您的帮助！

Is there a way to receive multiple files using Flask's built-in upload handling? Thanks for any help!

推荐答案

您可以使用方法 flask.request.files 的="noreferrer">getlista>，例如:

You can use method getlist of flask.request.files, for example:

@app.route("/upload", methods=["POST"])
def upload():
    uploaded_files = flask.request.files.getlist("file[]")
    print uploaded_files
    return ""
