Yahoo YQL RSS – 错误请求

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：

 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 = '
'; if(res.query && res.query.results && res.query.results.item){ //code goes here } else { html += '
The feed is currently not available due to server issues. Check back soon!
'; } html += '
'; rssWrap.append(html); }, "jsonp"); 

它工作正常但现在我在json响应上遇到错误请求问题而没有错误的文本描述：

 {"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url query： link进行测试

尝试检查YQL控制台时，它工作正常：

 { "query": { "count": 10, "created": "2017-08-25T02:54:38Z", "lang": "en-US", "diagnostics": { "publiclyCallable": "true", "url": { "execution-start-time": "1", "execution-stop-time": "8", "execution-time": "7", "content": "https://www.top1000funds.com/feed/most-popular-posts/" }, "user-time": "8", "service-time": "7", "build-version": "2.0.164" }, "results": { "item": [ { "title": "OTPP's private equity revolution", "link": "https://www.top1000funds.com/profile/2017/08/03/otpps-private-equity-revolution/", "pubDate": "Thu, 03 Aug 2017 06:39:33 +0000", "creator": "Sarah Rundell", "guid": { "isPermaLink": "false", "content": "http://www.top1000funds.com/?p=17673" }, "description": "

有什么建议吗？

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，则随机加载错误或罚款。

我认为我们（用户）无法做到这一点。 雅虎需要解决这个问题……

Answer 2

我有完全相同的问题。 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。

我能找到的唯一可能的解决方案是在线程中： jQuery with YQL RSS Feeds随机返回null

它表明它可能与API上的超时有关，而YQL控制台上没有该超时。

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

我相信，在试用YQL控制台时，它会缓存结果。 如果你进入调试模式，它将不会使用cahed结果，所以你会看到更好的问题。

Answer 4

在我看来，从2天开始，一切都运作良好。
