使用Flask上传文件夹和文件 [英] Folder and files upload with Flask
本文介绍了使用Flask上传文件夹和文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我可以通过遵循上传文件
来上传带有烧瓶的文件:-
<form>标签用enctype=multipart/form-data标记，并以该形式放置<input type=file>. - 应用程序从请求对象上的文件字典访问文件.
- 使用文件的
save()方法将文件永久保存在文件系统中的某个位置.
但是我不知道如何上传文件夹或某些文件.我搜索了一下，发现使用Flask上载多个文件.
但是，我仍然不知道如何上传文件夹和属于该文件夹的文件.
请您告诉我如何?
我正在研究的目录树:
.
├── 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>
解决方案
file = request.files['file']
将其更改为
file = request.files['file[]']
I can upload a File with flask by following Uploading Files:
- A
<form>tag is marked withenctype=multipart/form-dataand an<input type=file>is placed in that form. - The application accesses the file from the files dictionary on the request object.
- Use the
save()method of the file to save the file permanently somewhere on the filesystem.
But I don't know how to upload folder or some files. I searched, and I found Uploading multiple files with Flask.
However, still I don't know how to upload a folder and files that belong to the folder.
Could you please tell how?
Directory tree I am working on:
.
├── manage.py
├── templates
│ ├── file_upload.html
│ └── hello.html
└── uploads
├── BX6dKK7CUAAakzh.jpg
└── sample.txt
Source code of uploading file:
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)
template for file uploading(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>
解决方案
file = request.files['file']
change it to
file = request.files['file[]']
