Questions about POST data cannot be captured

A basic question about POST data capture failure: apache + php $. post ('/user/daka', {& quot; test & quot;: & quot; 1 & quot;}, function (data ){....}) & nbsp; $. post ('/user/daka/', {& quot; test & quot;: The POST cannot capture data.
Ask a basic question:

Environment apache + php

$. Post ('/user/daka', {"test": "1"}, function (data ){....})
$. Post ('/user/daka/', {"test": "1"}, function (data) {...}) // multiple slashes behind the url

The first line of code, $ _ POST cannot obtain data, and the second line can.
Should this be apache configuration or php configuration?

------ Solution --------------------
It's neither apache nor php, but you're wrong.

If a slash is added, it is the default index file in this directory.
If it is not added, it is the daka file... of course, you do not have the data returned by the daka file, right?
