单击提交按钮实际上没有任何作用。提交空白表单将触发对必填字段的验证，但是按要求填写表单会导致表单不提交/提交按钮不起作用。模板具有CSRF_Token，“提交”按钮位于form标记中，并且form标记具有指向正确方向的action属性。 Chrome不会发出任何错误，因此我只能继续操作。

您写的内容看起来真的很复杂，为什么不尝试简单的东西-
$request->header('User-Agent');
在您的 views.py 和 connect.html 表单中，只需编写-
@app.route("/connect",methods=['GET','POST'])
def connect():
if request.method=='GET':
return render_template('connect.html')
if request.method=="POST":
return render_template('Thankyou.html',name=request.form['name])
最后一页 Thankyou.html 看起来像这样-
<form name="connect" method="post" action="{{ url_for('connect') }}">
<input class="t1" type="text" id="email" name="email" placeholder="Your Email ID">
<input class="t2" type="text" id="name" name="name" placeholder="name">
<button class="btn btn-primary but" type="submit">Send</button>
</form>
