十万火急的问题。。。。。关于python或者perl解决http请求

post url是：
http://16.157.53.22:8080/HPCC/rest/monitoring/alert.APPLICATION_XML?instancekey=a

由于发送post之后需要进入login页面进行登录才可以成功发送，login页面表单：

<form action="j_spring_security_check">
<label for="j_username">Username</label>
<input type="text" name="j_username" id="j_username" />
<br/>
<label for="j_password">Password</label>
<input type="password" name="j_password" id="j_password"/>
<br/>
<input type='checkbox' name='_spring_security_remember_me'/> Remember me on this computer.
<br/>
<input type="submit" value="Login"/>
</form>

今天刚接触python。。。求大侠帮助
