我使用這個Python代碼：
@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")
當我點擊提交按鈕，返回「錯誤的請求 瀏覽器（或代理）發送了一個這個服務器無法理解的請求。「所以當我點擊我的domainname.com/quiz上的按鈕時會發生這種情況。我注意到當我點擊按鈕時，域名背後的「/ quiz」消失。我究竟做錯了什麼？
在你的源代碼中，你還有裝飾器和函數之間的空行嗎？ – vZ10
