Automatska provjera promjene datoteke na serveru
Tražim postoji li neki program/automatizirani način provjere promjene nekoliko desetaka datoteka na XX serverima? Npr. imam http://www.server1.com/datoteka1.pdf, Npr. imam http://www.server2.com/datoteka151.pdf, Npr. imam http://www.server4.com/datoteke/datoteka1.pdf... I želio bih da mi program provjeri jesu li se one mijenjale (ne treba biti ograničeno na ime, već na i veličinu npr. tako da ime može ostati isto, ali se datoteka mijenjala) od zadnjeg puta kada sam im pristupio/provjeravao za "update"? Hvala puno |

hmmm...nisam ga pronašao korisnim za to što ja tražim, ili nisam dobro gledao? tražim nešto gdje ne bi uopće trebao "skidati" datoteku (ajmo reći ručno) već bi ja upisao http://www.website.com/datoteka1.pdf http://www.website.com/datoteka2.pdf http://www.website.com/datoteka3.pdf kliknuo "Check" i on bi napisao "File datoteka2.pdf on http://www.website.com has changed since the last check" - tako nekako |

svebee, izprogramirao sam ti program koji radi baš to što trebaš. U check.txt upises URL-ove koje zeliš testirati (svaki URL u novi red). Zatim pokreneš last-modified.exe koji će kreirati report.txt u koji se zapisuje ovakvo nešto: Tue, 30 Oct 2007 19:06:43 GMT http://sunearthday.nasa.gov/2008/mat..._1920x1200.jpg Tue, 30 Oct 2007 19:07:39 GMT http://sunearthday.nasa.gov/2008/mat..._1920x1200.jpg Fri, 09 Feb 2007 19:08:47 GMT http://sunearthday.nasa.gov/2007/mat...007_folder.pdf Program je skroz spartanski bez opcija. Radi tako da requesta header, te ako server vrača header sa podatkom "Last-Modified" zapisuje u report.txt Ubacio sam ti par primjera u check.txt, gdje je Opera Setup exe dosta velika no svejedno brzo provjeri kada je uplodana. Neki serveri ne vračaju header Last-Modified tako da ti neki URL-ovi neće raditi. Program možeš skinuti tu: last-modified.zip |

Svaka cast na trudu, ali FFS, citav megabajt za dobiti HTTP header i to jos CLI aplikacija? @svebee Code:
/*Project 1: Simple HTTP Client and Server For CS586(Computer Network Architectures), Fall 2002 2002-10-05 Bao Jie Dept of Computer Science Iowa State University baojie@cs.iastate.edu Command line usage: client [-h] [-d <time-interval>] <URL> The client takes two options "-h" and "-d" and a required argument <URL>. <URL> specifies the URL of the object that the client is requesting from server. The format is http://hostname[:port]/filepath. Option "-h" specifies that the client only wants the response headers to be sent back from server. You should use HEAD method in your HTTP request when "-h" is specified in the command line. Option "-d" along with its argument <time-interval> specify that the client wants the object only if it was modified in the past <time-interval>. <time-interval> is in the format "day:hour:minute" For example, if "-d 1:2:15" is included in the command line, then the client wants to get the object only if it was modified in the past 1 day, 2 hours and 15 minutes. When -d option is specified, the client should include an "If-Modified-Since:" header in the HTTP request and the value of this header is computed using the current time and the <time-interval> argument. In client.c, you need to parse the <URL> given in the command line, connect to the server, construct an HTTP request based on the options specified in the command line, send the HTTP request to server, receive an HTTP response and display the response on the screen. You are provided with the code segments for parsing the URL.
