Hey Everyone,
I have a pretty interesting problem that I thought I would try and get
some feedback on. The following method below accepts a URL string as a
parameter ex "http://www.google.com,"; and it uses regular expressions
to try and find the images in the html. The odd thing is.... that I
have tested it over and over again.... and it has always grabbed the
images and worked exactly as I coded it too, but lately it has been
telling me that the URI class doesn't have a read method.... when it
must because I have been using it!
I am just so confused why rails would suddenly have this issue, and I
am wondering if anyone can make heads or tails out of it. The code is
posted below.
Thanks!
<================== CODE ===========================================>
def get_images(url)
@image_links = []
if validate_link(url) == false
return @image_links
end
if ((url =~ /\.jpg/)||(url =~ /\.png/)||(url =~ /\.gif/)) == nil
begin
uri = URI.parse(url)
str = uri.read
host = uri.host
rescue SystemCallError
return @image_links
end
@body = str.scan(/<body.+<\/body>/)
@images = str.scan(/(src=\"http.+\.jpg?\")/)
str = @images.to_s
@images = str.scan(/\".+?\"/)
@image_links = filter_images(@images)
@image_links.push("no_image.jpg")
else
@image_links.push(url)
@image_links.push("no_image.jpg")
end
return @image_links
end
