Question

为了使用jQuery创建跨域AJAX请求，我正在尝试使用YQL RSS。

select * from rss where url='https://www.top1000funds.com/feed/most-popular-posts/'

我的代码：

＆＃13;

var feed = "https://www.top1000funds.com/feed/most-popular-posts/";
var yql = "https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20rss%20where%20url%3D%22"+encodeURIComponent(feed)+"%22&format=json&diagnostics=true&callback=&rnd=_"+event.timeStamp;
console.log(yql);

$.getJSON(yql, function(res) {
    var html = '<div class="feedListWrap">';
    if(res.query && res.query.results && res.query.results.item){
        //code goes here
    } else {
        html += '<div class="feedEmpty">The feed is currently not available due to server issues. Check back soon!</div>';
    }
    html += '</div>';
    rssWrap.append(html);
}, "jsonp");

＆＃13;

它运行正常，但现在我在json响应上遇到Bad Request问题而没有错误的文字说明：

{"query":{"count":0,"created":"2017-08-25T03:09:09Z","lang":"en","diagnostics":{"publiclyCallable":"true","url":{"execution-start-time":"0","execution-stop-time":"2","execution-time":"2","http-status-code":"400","http-status-message":"Bad Request","content":"https://www.top1000funds.com/feed/most-popular-posts/"},"user-time":"2","service-time":"2","build-version":"2.0.164"},"results":null}}

您可以使用网址查询进行测试：link

尝试检查YQL控制台时，它可以正常工作：

请问任何建议？

Answer 1

我认为这是来自Yahoo YQL端的问题，与使用的代码或其他内容无关。如果刷新查询，他随机加载错误或罚款。

我认为我们（用户）无能为力。雅虎需要解决这个问题......

Answer 2

我遇到了完全相同的问题。我的代码有点不同，但原理是一样的 - 我正在通过YQL运行RSS提要以解决跨域问题..它工作正常，直到昨天但它现在返回相同的错误请求错误，但是，查询我每次都在YQL控制台中使用工作。

我能找到的唯一可行解决方案是：jQuery with YQL RSS Feeds randomly returning null

它表明它可能与YQL控制台上没有的API超时有关。

如果有人能够证实这一点或提供其他可能性，我也想听听他们的意见。

Answer 3

当我在YQL控制台上试用时，它会缓存结果，我相信。如果你进入调试模式，它不会使用计算结果，所以你会更好地看到任何问题。

Answer 4

从我这边看，自2天以来一切运作良好。
