@app.route('/index/', methods=['GET', 'POST'])
def index():
    import os
    if request.method == 'GET':
        return render_template('index.html')
    # POST
    file_obj = request.files.get('code')
    # print(file_obj)     # <FileStorage: 'bbs.zip' ('application/zip')>
    # print(file_obj.filename)    # bbs.zip
    print(type(file_obj))   # <class 'werkzeug.datastructures.FileStorage'>
    # from werkzeug.datastructures import FileStorage   # 查看源码
    file_path = os.path.join(os.getcwd(), 'files', file_obj.filename)
    # print(file_path)
