Ubuntu: Using Curl to Download an Image

Ubuntu: Using curl to download an image

curl without any options will perform a GET request. It will simply return the data from the URI specified. Not retrieve the file itself to your local machine.

When you do,

$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png

You will receive binary data:

                   |�>�$! <R�HP@T*�Pm�Z��jU֖��ZP+UAUQ@�
��{X\� K���>0c�yF[i�}4�!�V̧�H_�)nO#�;I��vg^_ ��-Hm$$N0.
���%Y[�L�U3�_^9��P�T�0'u8�l�4 ...

In order to save this, you can use:

$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png > image.png

to store that raw image data inside of a file.

An easier way though, is just to use wget.

$ wget https://www.python.org/static/apple-touch-icon-144x144-precomposed.png
$ ls
.
..
apple-touch-icon-144x144-precomposed.png

How do I download an file(image) in a folder on my Ubuntu server?

If you want to be able to access the files over HTTP then you need to setup a webserver.

If you want to simply download the files really quick, the fastest way is to go into the directory you want to download and run

python3 -m http.server

This will make your files accessible at http://ip_of_server:8080/.

If you however intend to make the files accessible for a large amount of people, you will want to install a dedicated webserver such as for example apache or nginx. These will allow full customisation such as for example password protecting files/directories.

Downloading a file to Ubuntu with libcurl C++, simple example doesn't work

Your link does not point to an existing file. With a correct link it works for me. Try this:

const char *url = "https://i.imgur.com/oRtvmGT.jpg";

wget/curl large file from google drive

Have a look at this question: Direct download from Google Drive using Google Drive API

Basically you have to create a public directory and access your files by relative reference with something like

wget https://googledrive.com/host/LARGEPUBLICFOLDERID/index4phlat.tar.gz

Alternatively, you can use this script: https://github.com/circulosmeos/gdown.pl

Download Multiple Images with Curl

Hello,

You found the answer by yourself.

You must as you said put the images in an array and loop on it.

$urls = ['https://images.somesite.1.jpg', 'https://images.somesite.2.jpg'];

$my_save_dir = 'images/';
foreach ($urls as $url) {
   $ch = curl_init($url_to_image);
   $filename = basename($url);
   $complete_save_loc = $my_save_dir . $filename;

   $fp = fopen($complete_save_loc, 'wb');

   curl_setopt($ch, CURLOPT_FILE, $fp);
   curl_setopt($ch, CURLOPT_HEADER, 0);
   curl_exec($ch);
   curl_close($ch);
   fclose($fp);
}

Download Images from a site via a command line

You get the same behavior when running wget https://www.bunlongheng.com/ without all that stuff with images. Running wget -d https://www.bunlongheng.com/ 2>&1 | less provides some information: there is an index error in a php file :

ErrorException: Undefined offset: 1 (View: /home/forge/bheng/resources/views/layouts/fe/meta.blade.php) (View: /home/forge/bheng/resources/views/layouts/fe/mSkipping 512 bytes of body: [eta.blade.php) in file /home/forge/bheng/storage/framework/views/0b4178e309ed0339363606e08a7e6d3f33347b7f.php on line 76

  etc

As proposed by @mhdINbY, if you put a user agent of an existing browser (I tried mine : -U "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0" everything went OK.

I would suspect that your framework analyses the user agent HTTP header in order to format the output accordingly and has a bug when it doesn't know the user agent you are using, here User-Agent: Wget/1.17.1 (linux-gnu)

How to download a file into a directory using curl or wget?
