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
<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.
A <form> tag is marked with enctype=multipart/form-data and 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.
我可以通过遵循上传文件
来上传带有烧瓶的文件: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:
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.txtSource 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[]']
