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
