在javascript中处理youtube数据api中的错误 [英] handling errors in youtube data api in javascript
问题描述
成功加载之一就是：
http://gdata.youtube.com/feeds/api/videos/N7m86aMNjlQ?callback=jsonp1335008664824&alt=json-in-script
然而，当视频是私有或不存在时，它只返回一条带有http错误状态代码的消息。
However, when the video is private or doesn't exist, it returns just a message with an http error status code.
我创建了一个独特的示例回调函数名称，如jsonp1335008664824，并将url附加为脚本标记的src，并在脚本加载时捕获该函数。但是，如果它返回错误，youtube不会将内容作为回调函数返回，我无法捕获它们中的任何一个。因为脚本标签没有onerror属性，我甚至不知道它是加载还是返回了404或503状态代码之类的错误。
I create an example unique callback function name like "jsonp1335008664824" and append the url as src for a script tag and catch the function when the script loaded. However if it returns an error, youtube doesn't return the content as a callback function and I can't catch any of them. Because script tag doesn't have "onerror" attribute, I don't even know whether it's loading or returned an error like 404 or 503 status codes.
似乎是只有在处理脚本标签时才设置超时功能。然而，这不是一个可靠的方法，所以我正在寻找另一种选择。我知道，即使我可以捕获状态代码，我也无法收到错误消息，但正如我所见，只有两个状态代码和两个错误，404为未找到视频或503为视频是私有。
It seems the only whay to handle it is setting timeout function when I append script tag. However it's not a reliable way to do that so I'm looking for another option. I know that even I can catch the status code, I can't get error message but as I see, there's only two status code and two errors that are 404 for "Video not found" or 503 for "Video is private".
推荐答案
我从Youtube开发者论坛得到了答案。因此，jsonc是处理这类请求的更好方法。而这个开发请求变成了这种布局：
http://gdata.youtube.com/feeds/api/videos/zkZBEnBjOjY?callback=jsonp1335008664915&alt=jsonc&v=2
I got the answer from Youtube Developer Forum. As a result, jsonc is a better way to handle these kind of request. And this this development the requests became this layout: http://gdata.youtube.com/feeds/api/videos/zkZBEnBjOjY?callback=jsonp1335008664915&alt=jsonc&v=2
我也从这里了解到，我们可以在Youtube Data Api中使用XMLHTTPRequest。这很棒，因为我们可以从现在开始发出POST和PUT请求。
And also as I learned from here, we can use XMLHTTPRequest in Youtube Data Api. This is awesome because we can make POST and PUT request from now on.
