解决方法：


if you are using blueprints, url_for should be invoked as url_for(blueprint_name.func_name).

main 为蓝图的名字

修改后的代码为



@main.route(‘/sendfile‘, methods=[‘GET‘, ‘POST‘])
def sendfile():
    if request.method == ‘POST‘:
        f = request.files[‘file‘]
        basepath = path.abspath(path.dirname(__file__))
        upload_path = path.join(basepath, ‘static/uploads‘)
        f.save(upload_path + ‘/‘ + secure_filename(f.filename))
        return redirect(url_for(‘main.sendfile‘))
    return render_template(‘sendfile.html‘)
