Hi

Any idea how I can use curl/snoopy to download file from Javascript based submit button?The file name in url http://localhost:8080/test/test_20090319.zip changes every day.

 

Here is the form page(test.jsp) and LiveHTTPHeader output. 

 

<html>

<head>

<title>Untitled</title>

<SCRIPT language="JavaScript1.2"> 

function poponload()

{

var url='http://localhost:8080/test/test_20090319.zip'; 

testwindow= window.open (url);

}

</script> 

</head>

 

<body>

 

<form method="GET" action="test.jsp" onsubmit="javascript:poponload()">

 

<input type="submit"

name="download"

value="OK" 

/>

</form>

 

 

</body>

</html>

if you use the code tags around your php or even html snippets, you will likely get more help

[ code ]Like this but without the spaces in the tags[ /code ]

would be

Like this but without the spaces in the tags

 

How do you plan on finding out what the filename is everyday?

I was hoping by being able to invoke the javascript:poponload using curl I don't need to specify the exact file name.(or is it too wishfull ?)

The file name always ends with _YYYYMMDD.zip .

So you need to pull out a filename from a webpage and The file name always ends with _YYYYMMDD.zip

 

how about an over complicated untested script

<?php
$DATA= <<<DATA

<html>
<head>
<title>Untitled</title>
<SCRIPT language="JavaScript1.2">
function poponload()
{
var url='http://localhost:8080/test/test_20090319.zip';
testwindow= window.open (url);
}
</script>
</head>

<body>

<form method="GET" action="test.jsp" onsubmit="javascript:poponload()">

<input type="submit"
name="download"
value="OK"
/>
</form>


</body>
</html>
DATA;

if (preg_match('/\'([^\']*?(?:19|20)[0-9]{2}(?:0[1-9]|1[012])(?:0[1-9]|[12][0-9]|3[01])\.zip)\'/i', $DATA, $regs)) {
$result = $regs[1];
}

echo $result;
?>

Thanks.

My bad, I should have provided more details.

What I'm really trying to do is creating a shell job which everyday downloads the zip file from a site. The path to the file (http://localhost:8080/test/test_20090319.zip) is actually created on the fly by javascript when the user presses the download button. So the the content of the page does not contain the file path/name .

I guess my question is how I can have curl call the javascript to download the file ?
