Dotaz: Jak si stahnout www stranku

[JF]

Dobry den,

chtel bych si stahnout command line prikazem www stranku. Vsude jinde se mi to dari, jen jedna krabicka od Ubiquity odolava.

Nechapu proc je to takhle slozite, ale krabicka vyzaduje zadat Content-Type: multipart/form-data; a to wget neumi. Stary pristup --user --password nepodporuje.

Alespon jsem toto odsnifoval pri prohlizeni z Firefoxu?

Nemate nejaky napad, jak ze skriptu stahovat podobne zaheslovane stranky.

Kolacek se vyrobit da:

xxx:/home/f/monitor# wget --load-cookies /tmp/cookies.txt --keep-session-cookies --save-cookies /tmp/cookies.txt --post-file /etc/nakrm.txt "http://10.23.204.242/login.cgi?uri=/stainfo.cgi" -O /tmp/login.cgi

Ale korektne zalogovat se mi nedari.

dekuji Jara

To je přihlášení přes webový formulář. Ten můžete s wgetem poslat pomocí parametru --post-data nebo --post-file. Pokud ovšem ten server zpracuje i data ve formátu application/x-www-form-urlencoded, protože alespoň podle mé manuálové stránky wget neumí multipart/form-data. Pokud server opravdu vyžaduje multipart/form-data (nechápu proč, není tam upload souboru), pak zkuste třeba curl.

Wgetem jsem take zkousel --post-file. Kdyby se dalo k --pst-file pridat jeste neco jako nepridavej hlavicku, tak by to slo.

Jenze hlavicka z wgetu dopadne takhle spatne. A bohuzel ji zarizeni nesezere.

Hlavičky nemůžete mít na začátku souboru, ty musíte poslat parametrem --header.

Dekuji moc, uz se podarilo stranku nacist, ale bohuzel jen z Windows :(. Tam mam wget 1.11.4

wget --load-cookies cookies.txt --keep-session-cookies --save-cookies cookies.txt --header="Content-Type: multipart/form-data; boundary=---------------------------7da2ce24280476" --post-file=nakrm.txt "http://10.23.204.242/login.cgi?/stainfo.cgi"

wget --keep-session-cookies --load-cookies cookies.txt

V Linuxu mam 1.11.1 a ten stranku ne a ne nacist. Ale alespon jsem se dostal o krok dal.
