如何使用get方法跨域jquery ajax響應？

Question

如何使用jQuery或帶有node.js的東西向json文件發出異步跨域請求（GET）？ 我有我的API，我只需要向文件發出請求

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

});

結果

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.

要么

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

結果

undefined

Answer 1

您的網址回調函數缺少= 。 這是正確的網址。 然后嘗試一下。

1. 確保控制台中沒有任何404錯誤。

2. 檢查控制台是否有其他錯誤。

    $.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} });
