_InetGetSource stops workings after 300 calls?

10 posts in this topic

I know this sounds odd, but I couldn't think of anything else.

I made a script that enters on a site and gets some info from this page. There are 92000 pages in total. After getting the data from exactly 300 pages, the script stops getting the data.

Here is the code:

#include <Excel.au3>
#include <String.au3>
#include <Array.au3>
#include <INet.au3>

$excel_read = _ExcelBookOpen("C:\Users\Macedo\Desktop\correct_links.xlsx")
$excel_write = _ExcelBookOpen("C:\Users\Macedo\Desktop\info.xlsx")

$line = 1
$name = ""

While $line < 92480
    $HTML = _INetGetSource(_ExcelReadCell($excel_read,$line,1))
    $name = _StringBetween($HTML,'<title>',',')
    If @error == 1 Then
        $name = "Unavailable"
        SetError(0)
    Else
        $name = StringStripWS($name[0],4)
    EndIf

    _ExcelWriteCell($excel_write,$name,$line+1,1)

    $line = $line + 1
WEnd

After 300 pages, $name is always set to "Unavailable", which means @error == 1.

First I thought there was something special with page number 300, but that's not it. If I start getting info from, let's say, page 250, the script will work till page 550. :)

Any ideas guys? Thanks in advance!

The @error test is for _stringBetween() not _InetGetSource.

So have you checked what _InetGetSource() is returning when it goes wrong and what its error is?

I will try to do that, thanks for the suggestion.

I'd hazzard a guess that the website is putting the blockers on you after that many downloads, after all you begin to look like a bot.

I hope that's not the case :) I will try using IE UDF just to confirm this hypothesis.

That won't Fix the problem, if you "Ping" a Website 300 times in 10 seconds of course it will look suspicious! Edited by guinness

It could be that AutoIt or IE is getting out of allowed FD or other kind of handle. To get rid of a possible issue with _Excel stuf, could you first load an array with the Excel names then change your _InetGetSource line to supply the name from the array. Then if it still coughs after 300 calls, we're sure the issue is with _Inet* not _Excel* supplying wrong data (unlikely but not 100% excluded).

pedmacedo,

_inetgetsource is just running inetread. I've used inetread to iterate over 1000+ pages on occasion. I don't know what the Excel function is but would hazard a guess that the server is throttling traffic.

That has been suggested before and is most likely what's happening. I use _InetRead or friends routinely but I'm unsure if I reach 300 downloads in a single run, that's why I was attempting to simplify hings a bit more.

jhcd,

yes, had an invalid premise that lead to bad conclusions a couple hours ago. Guinness corrected the code and reminded me that "assumptions make an ass out of you and me".

Something similar happend to me a while back while trying to automate a free webservice.

Tried to run a task to many times and it failed after a while, when I physically navigated to the site, I was met with a blank page, so I figured it was IP related.

It may well be something similar, I think they call it hammering.
