我可以通过这个例子上传一个带烧瓶的文件:
但我不知道如何上传文件夹或某些文件。我搜索过,我发现了这个: Uploading multiple files with Flask。最后,我得到了如何上传多文件上传。 我会告诉你下面的代码:(这是一个好习惯吗?我想知道)
@app.route('/upload/',methods = ['GET','POST'])
def upload_file():
if request.method =='POST':
files = request.files.getlist('file[]',None)
if files:
for file in files:
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'],filename))
return hello()
return render_template('file_upload.html')
但是,我仍然不知道如何上传属于该文件夹的文件夹和文件。 你能告诉我怎么样?
我正在处理的目录树:
. ├── manage.py ├── templates │ ├── file_upload.html │ └── hello.html └── uploads ├── BX6dKK7CUAAakzh.jpg └── sample.txt
上传文件的源代码:
from flask import Flask,abort,render_template,request,redirect,url_for
from werkzeug import secure_filename
import os
app = Flask(__name__)
UPLOAD_FOLDER = './uploads'
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
@app.route('/')
def index():
return redirect(url_for('hello'))
@app.route('/hello/')
@app.route('/hello/<name>')
def hello(name = None):
return render_template('hello.html',name=name)
@app.route('/upload/',methods = ['GET','POST'])
def upload_file():
if request.method =='POST':
file = request.files['file']
if file:
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'],filename))
return hello()
return render_template('file_upload.html')
if __name__ == '__main__':
app.run(debug = True)
文件上传模板(manage.py):
<!doctype html>
<title>Upload new File</title>
<h1>Upload new File</h1>
<form action='' method="POST" enctype="multipart/form-data">
<p><input type='file' name='file[]' multiple=''>
<input type='submit' value='upload'>
</p>
</form>
答案 0 :(得分:3)
file = request.files['file']
将其更改为
file = request.files['file[]']

这里的问题是,烧瓶的app.config
与自身并不相关,它是绝对的。所以当你把:
UPLOAD_FOLDER = './uploads'
flask找不到此目录并返回500
错误。
如果你改为:
UPLOAD_FOLDER = '/tmp'
然后上传您的文件并导航到您将看到的/ tmp /目录。
您需要编辑正确目录的路径,以便正确上传文件。
