问是否有任何可公开访问的JSON数据源可以使用真实数据进行测试？

EN

// Querystring, "tags" search term, comma delimited
const query = "https://www.flickr.com/services/feeds/photos_public.gne?tags=soccer&format=json&jsoncallback=?";


// This function is called once the call is satisfied
// http://stackoverflow.com/questions/13854250/understanding-cross-domain-xhr-and-xml-data
let mycallback = function(data) {
  // Start putting together the HTML string
  let htmlString = "";

  // Now start cycling through our array of Flickr photo details
  $.each(data.items, function(i, item) {
    // I only want the ickle square thumbnails
    let sourceSquare = (item.media.m).replace("_m.jpg", "_s.jpg");

    // Here's where we piece together the HTML
    htmlString += '<li><a href="' + item.link + '" target="_blank">';
    htmlString += '<img title="' + item.title + '" src="' + sourceSquare;
    htmlString += '" alt="';
    htmlString += item.title + '" />';
    htmlString += '</a></li>';

  });

  // Pop our HTML in the #images DIV
  $('#images').html(htmlString);
};


// Ajax call to retrieve data
$.getJSON(query, mycallback);
