Cherrypy 404 错误

Question

404 未找到

The path '/getCustomer' was not found.

Traceback (most recent call last):
File "C:\Python33\virtualenviorments\cherrypro\lib\site-packages\cherrypy\_cprequest.py",      line 670, in respond
response.body = self.handler()

cherrypy._cperror.NotFound: (404, "The path '/getCustomer' was not found.")

当我尝试显示从下拉列表中选择的用户的表格时出现此错误......这是 py 代码

这里是html代码

<h1>{{salutation}}{{target}}</h1>
<p>Select a name from thee list:</p>

<form action='getOneCustomer' method='post'>
<u1>
<select name = 'customerName'>
        {%for n in myList%}
        <option>{{n}}</option>
        {%endfor%}
</select>
</u1>
        <p><input type='submit' value='Submit'/></p>
</form>
<p>Customer data:</p>
<table style='width:300px'>
<tr>
    <th>Id</th>
    <th>Name</th>
    <th>Email</th>
    <th>Address</th>
    <th>City</th>
</tr>
<tr>
    {%for n in customerTuple%}
    <td>{{n}}</td>
    {%endfor%}
</tr>

如何让路径可以正确访问？

Answer 1

唯一让我印象深刻的是在您的模板中您引用了 customerTuple，但在您的渲染命令中您使用的是 customerList。

希望这会有所帮助！
