将参数传递给python处理程序

Question

I am calling on a handler through a link in a table value , like this:

<td><a id="{{ test['test_name'] }}" href="/regex" >{{ test['test_name'] }}</a></td>

The handler has a SQL query that I want to run based on the id, or value of the cell, so when the link is clicked it send the unique name. I tried to read webapp2 documentation on URI routing but couldn't understand how to apply it to my problem.

Answer 1

In the documentation on URI Routing , the example shows:

app = webapp2.WSGIApplication([
    (r'/', HomeHandler),
    (r'/products', ProductListHandler),
    (r'/products/(\d+)', ProductHandler),
])

For your handler, you could use:

app = webapp2.WSGIApplication([
    (r'/regex/<test>', RegexHandler),
])

Then you would call it using:

<a href="/regex/{{ test['test_name'] }}" >{{ test['test_name'] }}</a>

(The id="..." attribute is not passed as part of the URL, it's an HTML attribute.)

Note: you may need to URL-encode the parameter test['test_name'] .
