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？我已经尝试了以下内容：

pre code>< form method =POSTenctype =multipart / form-dataaction = /上传 >
< input type =filename =file []multiple =>
< input type =submitvalue =add>
< / form>

然后打印 request.files ['file'] ：

  @ app.route（'/ upload'，methods = ['POST']）
 def upload（）：
 if _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'））
   
 
 
 
 
 
 code>< 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！
 
解决方案
您可以使用方法 getlist  of 
  @ app.route（/上传，methods = [POST]）
 def upload（）：
 uploaded_files = flask.request.files.getlist（file []）
 print uploaded_files

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>
And then printed the contents of request.files['file']:
@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'))
If I upload multiple files, it only prints the first file in the set:  
<FileStorage: u'test_file.mp3' ('audio/mp3')>  
Is there a way to receive multiple files using Flask's built-in upload handling? Thanks for any help!
解决方案
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 ""
