File copy

Hi,
I am facing a problem to copy the file.

I am getting path of the file like this
"http://photos-d.ak.fbcdn.net/photos-ak-snc1/v2574/90/75/704291251/457931_8289306.jpg".
I want to copy this file locally. I am trying to do this by using

File.copy(“http://photos-d.ak.fbcdn.net/photos-ak-snc1/v2574/90/75/704291251/457931_8289306.jpg","/images”);

I am getting an error
Invalid argument -
http://photos-d.ak.fbcdn.net/photos-ak-snc1/v2574/90/75/704291251/457931_8289306.jpg

I know that this is not a directory path. Is any one knows how to copy
this file?

Thanks
Tushar

Why can't you use wget command in system or popen to download it ?
It's my suggestion

Hello Tushar,

Take a look at 'net/http', which is included in the ruby standard library:
http://ruby-doc.org/core-1.9/classes/Net/HTTP.html

For example the following code will download and save the ruby logo
off ruby-lang.org:

require 'net/http'
uri = URI.parse('http://www.ruby-lang.org/images/logo.gif'\)
Net::HTTP.get_response(uri) do |response|
  File.open('/tmp/logo.gif', 'w') {|f| f.write response.body }
end

There are various other ways to go about doing this - some of which
have been mentioned above - but 'net/http' is a good place to start.

solidarity,
lasitha.

Hi,

I write the code like this
"
browser=Watir::IE.new
    browser.visible=false
    browser.goto(params[:photo_url])

    idx = 0

    # using the images collection, iterate through all of the images on
a page
    browser.images.each do |x|
      idx += 1
      # apparently the string accepted by the string method will not
allow variable substitution
      original_type= x.src[-4,4]
      type=".gif" if original_type == ".gif"
      type=".jpg" if original_type == ".jpg"
      type=".png"if original_type == ".png"
      type=".bmp" if original_type == ".bmp"
      type="jpeg" if original_type == ".jpeg"
      x.save('/images/')
    end
"
I am getting an error

" The AutoIt dll must be correctly registered for this feature to work
properly "
How to resolve this?
Thanks,
Tushar

Hi,
I went through this link
http://www.mail-archive.com/wtr-general@rubyforge.org/msg06628.html
and my dll registered successfully.
I changed my code like this
"
browser=Watir::IE.new
    browser.visible=true
    browser.goto(params[:photo_url])

    idx = 0

    # using the images collection, iterate through all of the images on
a page
    browser.images.each do |x|
      idx += 1
      # apparently the string accepted by the string method will not
allow variable substitution
      original_type= x.src[-4,4]
      type=".gif" if original_type == ".gif"
      type=".jpg" if original_type == ".jpg"
      type=".png"if original_type == ".png"
      type=".bmp" if original_type == ".bmp"
      type="jpeg" if original_type == ".jpeg"
      x.save('E:\Rails2.2\integrateSNS\public\images')
    end
"
It open a new tab and open that image and also open windows standard sve
pop up and hangs.
What should I do for this?

Thanks,
Tushar

Hi,

File.copy("http://photos-d.ak.fbcdn.net/photos-ak-snc1/v2574/90/75/704291251/457931_8289306.jpg","/images&quot;\);

For example the following code will download and save the ruby logo
off ruby-lang.org:

Another possibility:

irb(main):001:0> require 'open-uri'
=> true
irb(main):003:0> open("http://www.ruby-lang.org/images/logo.gif&quot;\) do |f|
irb(main):004:1* File.open("logo.gif", "w"){|out| out.write f.read}
irb(main):005:1> end

Jesus.

Hi Gandhi,

Oops. please try with separate .rb file first.

After that try to implement in rails.

Hi Gandhi,

Please try to run the code in separate .rb file. Update here in case you
get any errors.
