这是我的代码..
require "open-uri"
base_url = "http://en.wikipedia.org/wiki"
(1..5).each do |x|
# sets up the url
full_url = base_url + "/" + x.to_s
# reads the url
read_page = open(full_url).read
# saves the contents to a file and closes it
local_file = "my_copy_of-" + x.to_s + ".html"
file = open(local_file,"w")
file.write(read_page)
file.close
# open a file to store all entrys in
combined_numbers = open("numbers.html", "w")
entrys = open(local_file, "r")
combined_numbers.write(entrys.read)
entrys.close
combined_numbers.close
end
如你看到的。它基本上会抓取维基百科文章 1 到 5 的内容,然后尝试将它们组合成一个名为 numbers.html 的文件。
它首先做对了。但是当它到达第二个时。好像只是在循环中写第五条的内容。
我看不出我哪里出错了。有什么帮助吗?
