Question

import os
from flask import Flask, request, redirect, url_for
from werkzeug import secure_filename

UPLOAD_FOLDER = '/home/ubuntu/shared/'

app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER

@app.route("/", methods=['GET', 'POST'])
def index():
    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 redirect(url_for('index'))
    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" multiple="" name="file">
         <input type="submit" value="Upload">
    </form>
    <p>%s</p>
    """ % "<br>".join(os.listdir(app.config['UPLOAD_FOLDER'],))

if __name__ == "__main__":
    app.run(host='0.0.0.0', port=8000, debug=False)

如果我启动服务器并通过表单选择2个文件，它只会上传其中一个。我尝试了几个小时，阅读了大约15个主题，包括文档。纳达：c

编辑：我也尝试过改变：

        file = request.files['file']

成：

        file = request.files.getlist('file')

也不起作用。引号的类型也没有效果。那不是python3的东西吗？

我犯了一个非常新的错误，并没有转发上传的多个文件。此处的代码经过测试，没有同时上传4个文件的问题。我希望它对某人有用。

编辑：使用一些甜蜜的TLS_1.2和密码字段更新了代码。享受相当安全的上传服务器。密码通过HTTPS传输。

Flask HTTP Server不允许一次上传多个文件
