Python @app.route("/custom")，返回页面不起作用

Question

我正在将 Pythonanywhere.com 与 Flask 一起使用。我正在将此代码用于 html：

    <div class="main-content">

        <form class="main_page" method="POST" action=".">

            <div class="form-title-row">

我正在使用这个 python 代码：

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

def quiz():

    if request.method == "GET":
        return render_template("quiz_page.html")

    score = 0


    if (request.form["geen_multiplayer"] == "South Park: The Fractured but Whole"):
        score += 1

    if (request.form["gemaakt_rockstar"] == "Red Dead Redemption 2"):
        score += 1

    if (request.form["geen_shooter"] == "Red Dead Redemption 2"):
        score += 1

    if (request.form["alleen_ps4"] == "Crash Bandicoot N. Sane Trilogy"):
        score += 1

    if (request.form["heeft_splitscreen"] == "MotoGP™17"):
        score += 1

    if (request.form["gemaakt_codemasters"] == "Dirt 4"):
        score += 1

    if (request.form["wilde_westen"] == "Red Dead Redemption 2"):
        score += 1

    if (request.form["niet_sports"] == "Destiny 2"):
        score += 1

    if (request.form["voor_18"] == "The Elder Scrolls Online: Morrowind"):
        score += 1

    if (request.form["september_2017"] == "FIFA 18"):
        score += 1

    if request.method == "POST":
        return render_template("quiz_page.html")

当我点击提交按钮时，它返回“Bad Request 浏览器（或代理）发送了一个该服务器无法理解的请求。”所以当我点击我的 domainname.com/quiz 上的按钮时就会发生这种情况。我注意到当我点击按钮时，后面的“/quiz”域名消失了。我做错了什么？

Answer 1

将action="." 更改为action="#"。

action="." 导致请求被发送到当前 url 的上一级，这就是 /quiz 消失的原因。
