提问by Kamy D
I am only trying to fetch Youtube video's title. Can't seem to figure it. So far I have this:
我只是想获取 Youtube 视频的标题。好像想不通 到目前为止，我有这个：
q = 'https://www.googleapis.com/youtube/v3/videos?id='+ itemId +'&key='+ ytApiKey +'&fields=items(snippet(channelId,title,categoryId))&part=snippet' ;
$.ajax({
url: q,
dataType: "jsonp",
success: function(data){
alert(data.items[0].title);
console.log(data.snippet.title);
},
error: function(jqXHR, textStatus, errorThrown) {
alert (textStatus, + ' | ' + errorThrown);
}
});
Thanks,

I got it working using
我使用它工作
https://www.googleapis.com/youtube/v3/videos?id=itemId&key=apiKey&fields=items(snippet(title))&part=snippet
and
和
alert(data.items[0].snippet.title);
So, not much wrong with the syntax! But I found that the problem was really in the backend when setting up the Google API's 'allowed referers'. With V3 API, you can select which referers the API should belong to, so others cannot simply steal your API and use it. So the API will work if the request is originated from the domain name/IP you specify. When I don't give it restrictions, the code works, but when I do enter my domain it fails! I entered .mydomainname.com/, the same format as it was suggested, but it errors out somehow.. Now I've got figure out why.
所以，语法没有太大问题！但是我发现在设置 Google API 的“允许的引用者”时问题确实出在后端。使用 V3 API，您可以选择 API 应该属于哪些引用者，因此其他人不能简单地窃取您的 API 并使用它。因此，如果请求源自您指定的域名/IP，则 API 将起作用。当我不给它限制时，代码可以工作，但是当我输入我的域时它会失败！我输入了.mydomainname.com/，与建议的格式相同，但不知何故出错了..现在我已经弄清楚原因了。
