Voglio accedere a un sito di giornale e quindi scaricare le loro copie epaper (in PDF). Il sito mi richiede di accedere utilizzando il mio indirizzo e-mail e la mia password e quindi mi consente di accedere a quegli URL PDF.
Ho problemi a "impostare la mia sessione" in Wget . Quando accedo al sito dal mio browser, imposta due valori di cookie:
UserID=abc@gmail.com
Password=12345
Provai:
wget --post-data "UserID=abc@gmail.com&Password=12345" http://epaper.abc.com/login.aspx
Tuttavia, quello ha appena scaricato la pagina di accesso e salvata localmente.
Il FORM nella pagina di accesso ha due campi:
txtUserID
txtPassword
E i pulsanti radio come questo:
<input id="rbtnManchester" type="radio" checked="checked" name="txtpub" value="44">
Un altro pulsante:
<input id="rbtnLondon" type="radio" name="txtpub" value="64">
Se inserisco questo nella pagina login.aspx, ottengo lo stesso output
wget --post-data "txtUserID=abc@gmail.com&txtPassword=12345&txtpub=44" http://epaper.abc.com/login.aspx
Se lo faccio:
--save-cookies abc_cookies.txt
non sembra avere altro che il contenuto predefinito.
Per ultimo, se lo faccio anche io --debug
, dice:
...

Saving cookies to abc_cookies.txt.
Tuttavia, abc_cookies.txt mostra SOLO quanto segue:
# HTTP cookie file.
# Generated by Wget on 2011-08-16 08:03:05.
# Edit at your own risk.
(Non sono sicuro del motivo per cui non ricevo risposte su StackTranslate.it - forse Super User è un sito migliore - Usare Wget per scaricare file PDF da un sito che richiede l'impostazione di cookie .)
