現(xiàn)在很多網(wǎng)站上某些活動(dòng)都有限制同一IP只能投一票的規(guī)定,但是有時(shí)候迫于壓迫,又不得不想辦法多投幾票,以前是采用Apache里的HttpClient來(lái)實(shí)現(xiàn)這些功能,日前正在看Ruby,就用它也來(lái)玩下:
require 'net/http'
##獲得網(wǎng)頁(yè)內(nèi)容
def query_url(url)
return Net::HTTP.get(URI.parse(url));
end
#抓取cnproxy上所有的代理列表,并將結(jié)果保存到proxy.txt中去
#你可以修改這塊代碼或者其他的代理服務(wù)器列表
def find_all_proxy
z="3";j="4";r="2";l="9";c="0";x="5";i="7";a="6";p="8";s="1"
pf = File.new("proxy.txt","w+")
for page_no in 1..10
url = "http://www.cnproxy.com/proxy#{page_no}.html"
content = query_url(url)
#print content
## ^$?./\[]{}()+*
for array in content.scan(/<td>(.*?)<SCRIPT type=text\/javascript>document.write\(":"\+(.*?)\)<\/SCRIPT><\/td>/)
if array.length == 2
pf.write("#{array[0]}:#{eval(array[1])}\n")
end
end
end
pf.close
end
##處理請(qǐng)求
def open_url_with_proxy(url)
pf = File.open("proxy.txt","r")
d = []
pf.each { |line| d << line }
for var in d
print "User Proxy #{var}\n"
begin
proxy = Net::HTTP::Proxy(var.split(":")[0],var.split(":")[1].to_i)
print proxy.get(URI.parse(url));
#print proxy.start("www.google.com",80){|http|
# response = http.get('/index.html')
# puts response.body
#}
rescue
##吃掉異常
end
end
end
##主程序
begin
if !FileTest.exist?( "proxy.txt" )
find_all_proxy
end
open_url_with_proxy('http://www.google.com/index.html');
end
這里需要注意的是代理服務(wù)器的端口不能是String類型,Ruby竟然不會(huì)自動(dòng)轉(zhuǎn)換,搞得我浪費(fèi)了N多時(shí)間.
