jquery - 如何使用get方法跨域jquery ajax响应？

Question

如何使用 jQuery 或 node.js 对 json 文件进行异步跨域请求（GET）？我有我的 api，我只需要向文件发出请求

$.ajax({
    type: 'GET',
    url: "https://api.flightstats.com/flex/airports/rest/v1/json/active?appId=3a311b8b&appKey=5d67203e8afab7fe8d01e0debf177171",
    processData: true,
    data: {},
    dataType: "json"

});

结果

XMLHttpRequest
XMLHttpRequest cannot load https://api.flightstats.com/flex/airports/rest/v1/json/active?appId=3a311b8b&appKey=5d67203e8afab7fe8d01e0debf177171. Origin https://developer.flightstats.com is not allowed by Access-Control-Allow-Origin.

或者

$.ajax({
    type: 'GET',
    url: "https://api.flightstats.com/flex/airports/rest/v1/json/active?appId=3a311b8b&appKey=5d67203e8afab7fe8d01e0debf177171?callback?",
    processData: true,
    data: {},
    dataType: "jsonp"        
});

结果

undefined

Answer 1

您的 url 回调函数丢失=。这是正确的网址。然后尝试一下。

1. 确保您没有在控制台中收到任何 404 错误。

2. 检查控制台是否有任何其他错误。

   $.ajax({
       type: 'GET',
       url: "https://api.flightstats.com/flex/airports/rest/v1/json/active?appId=3a311b8b&appKey=5d67203e8afab7fe8d01e0debf177171?callback=?",
       processData: true,
       data: {},
       dataType: "jsonp",
       success:function(data){//do some thing with data},
       error:function(xhr, ajaxOptions, thrownError){//do with ajax errors}
   });

尝试这个：

$.ajax({
   type: 'GET',
   url: "https://api.flightstats.com/flex/airports/rest/v1/json/active?appId=3a311b8b&appKey=5d67203e8afab7fe8d01e0debf177171?callback=?",
   dataType: "jsonp",
   success:function(data){
       console.log(data);
   }      
});
