对应template 如下：
1） addbookMark.html
<div>
<form action="http://127.0.0.1:5000/getbookmark" method='post'>
<p>
enter name:
<input type="text" name = "name" ><br>
<p></p>
enter age:
<input type="text" name = "age" ><br>
<p></p>
enter job title:
<input type="text" name = "jobTitle" ><br>
</p>
<p>
<button type = "submit"> submit </button>
</p>
</form>
</div>
2） showDataBase.html
<div>
<table border =1 >
<tr>
{% for item in result[0].keys() %}
<th> {{item}}</th>
{% endfor%}
</tr>
{% for itemPer in result %}
<tr>
{% for item in itemPer.values() %}
<td> {{item}}</td>
{% endfor %}
</tr>
{% endfor %}
</table>
</div>
<a href="{{url_for('index')}}">back to main page </a>
