flask通过form表单一次上传多个文件
基本上，用了flask官网的示例代码（中文版，英文版），稍微做了修改。
1 import os 2 from flask import Flask, flash, request, redirect, url_for 3 from werkzeug.utils import secure_filename 4 5 UPLOAD_FOLDER = '/path/to/the/uploads' 6 ALLOWED_EXTENSIONS = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif']) 7 8 app = Flask(__name__) 9 app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
1 def allowed_file(filename): 2 return '.' in filename and \ 3 filename.rsplit('.', 1)[1] in ALLOWED_EXTENSIONS 4 5 @app.route('/', methods=['GET', 'POST']) 6 def upload_file(): 7 if request.method == 'POST': 8 for file in request.files.getlist('file'): # 这里改动以存储多份文件 9 if file and allowed_file(file.filename): 10 filename = secure_filename(file.filename) 11 file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename)) 12 13 return ''' 14 <!doctype html> 15 <title>Upload new File</title> 16 <h1>Upload new File</h1> 17 <form action="" method=post enctype=multipart/form-data> 18 <p><input type=file name=file> 19 <p><input type=file name=file> 20 <input type=submit value=Upload> 21 </form> 22 '''
这样就可以一次性提交多份文件。具体实现可参看相关源码。
