使用 Jquery 向 数据 API 发起简单的 ajax (JSONP) 请求
var data = { resource_id: 'b4851428-6ede-4774-a992-d9fbe4d31dd2', // 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) } });
import urllib url = 'https://vital-strategies.l3.ckan.io/zh_CN/api/3/action/datastore_search?resource_id=b4851428-6ede-4774-a992-d9fbe4d31dd2&limit=5&q=title:jones' fileobj = urllib.urlopen(url) print fileobj.read()
