如何检查Flask上的链接是否被点击？

@app.route('/link_clicked', methods=['POST'])
def link_clicked():
    # 处理链接点击的逻辑
    return 'Link clicked successfully'

<form action="/link_clicked" method="post">
  <input type="hidden" name="link_id" value="123">
  <a href="#" onclick="submitForm()">Click me</a>
</form>

<script>
  function submitForm() {
    document.forms[0].submit();
  }
</script>

from flask import request

@app.route('/link_clicked', methods=['POST'])
def link_clicked():
    link_id = request.form.get('link_id')
    # 处理链接点击的逻辑
    return 'Link clicked successfully'
