Question

我正在尝试允许用户将gematria计算提交到文本文件，以便我可以在将它们提交到数据库之前手动检查它们;因此我在一个模态中放置了一个简单的形式，输入类型=“提交”，但我一直得到一个400错误的请求错误，我无法弄清楚为什么这不起作用。

我正在使用带有烧瓶的Python3.6服务器端，而我没有使用带有html的bootstrap。

服务器端：

if request.form["action"] == "Send":
    Name = request.form["name"]
    Email = request.form["mail"]
    GematriaNum = request.form["gematria"]
    Source = request.form["source"]
    Calc = request.form["calc"]
    LIT = request.form["transliteration"]
    LANGY = request.form["translation"]
    NEWSL = request.form["newsletter"]
    BODYOF = Name + Email + GematriaNum + Source + Calc + LIT + LANGY + NEWSL

    with open("submiss.txt", "w") as submiss:
        submiss.write(BODYOF)

    return render_template("index.html")
    return redirect(url_for('index'))

网页代码：

    <!-- ...it's part of a nav bar. -->
    <!-- Trigger/Open The Modal -->
    <li><a id="myBtn">Submit your Calculations to the Database!</a></li>
</ul>

<script>
// Get the modal
var modal = document.getElementById('myModal');

// Get the button that opens the modal
var btn = document.getElementById("myBtn");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks the button, open the modal
btn.onclick = function() {
    modal.style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
    modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
    }
}
</script>

在提交按钮输入字段中缺少name="action"，并且没有处理新闻稿空值的处理情况复选框导致错误请求。

因为行动未设置，所以你永远不会进入

if request.form["action"] == "Send":

我在开发者模式（ F12 ）中使用Chrome来查找帖子形式数据。当我发现动作和简报不在帖子数据中时，我编辑了HTML live并且能够成功发布帖子。
