flask通过form表单一次上传多个文件

时间：2022-11-25 08:04:13

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。

 import os

 from flask import Flask, flash, request, redirect, url_for

 from werkzeug.utils import secure_filename

 UPLOAD_FOLDER = '/path/to/the/uploads'

 ALLOWED_EXTENSIONS = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif'])

 app = Flask(__name__)

 app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
 def allowed_file(filename):

     return '.' in filename and \

            filename.rsplit('.', 1)[1] in ALLOWED_EXTENSIONS

 @app.route('/', methods=['GET', 'POST'])

 def upload_file():

     if request.method == 'POST':

         for file in request.files.getlist('file'): # 这里改动以存储多份文件

             if file and allowed_file(file.filename):

                 filename = secure_filename(file.filename)

                 file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))

     return '''

     <!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>

       <p><input type=file name=file>

          <input type=submit value=Upload>

     </form>

     '''

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。
