CKAN Filedownload with API

I've set up a CKAN server with all necessary plugins. There is some content on the server (.csv files). Now I'd like to download a specific .csv file to change it locally and upload it again.

But I don't know how to download the complete file using the CKAN API.

Can someone help me?

The package_show API call will tell you the URL for the CSV so that you can download it.

e.g. this dataset: http://data.gov.uk/dataset/uk-open-access-non-vosa-sites is available on the API at: http://data.gov.uk/api/action/package_show?id=uk-open-access-non-vosa-sites which results in something like:

{
  "help": "http://data.gov.uk/api/3/action/help_show?name=package_show",
  "success": true,
  "result": 
  {
    "name": "uk-open-access-non-vosa-sites",
    "license_title": "UK Open Government Licence (OGL)",
    "resources": [
        {
            "description": "A list of Authorised Testing Facilities (ATFs) and DVSA test stations ",
            "format": "CSV",
            "url": "http://dft.gov.uk/vosa/images/Find%20your%20nearest%20ATF%20or%20VOSA%20test%20station.csv",
            "id": "bd9aaa9f-2a9c-45f8-8246-6b99dd78208a",
            "resource_type": "file",
        }
    ]
  }
}

from which you can see the url is http://dft.gov.uk/vosa/images/Find%20your%20nearest%20ATF%20or%20VOSA%20test%20station.csv which you can download e.g. using wget:

wget http://dft.gov.uk/vosa/images/Find%20your%20nearest%20ATF%20or%20VOSA%20test%20station.csv
