使用 Jquery 向 数据 API 发起简单的 ajax (JSONP) 请求

  var data = {
    resource_id: '99207d17-3009-4f87-9557-adabf700c842', // the resource id
    limit: 5, // get 5 results
    q: 'jones' // query for 'jones'
  };
  $.ajax({
    url: 'https://vital-strategies.l3.ckan.io/zh_CN/api/3/action/datastore_search',
    data: data,
    dataType: 'jsonp',
    success: function(data) {
      alert('Total results found: ' + data.result.total)
    }
  });
示例：Python » 
import urllib
url = 'https://vital-strategies.l3.ckan.io/zh_CN/api/3/action/datastore_search?resource_id=99207d17-3009-4f87-9557-adabf700c842&limit=5&q=title:jones'  
fileobj = urllib.urlopen(url)
print fileobj.read()
