youtube搜索api -太多的数据，我可以限制什么节点api返回

Question

我能以某种方式限制json对象返回的节点数量吗?我只使用每个搜索结果中的标题、作者和视频id，因此不需要加载和解析一百万个其他节点。无论如何做这个除了运行它认为一个服务器端代理?

不知道为什么每个人都说不，因为虽然你不能限制它只是title, channelId和videoId，你可以选择离开一些字段。有一个"fields"参数可以在Data Api的v3中使用。查看这里的文档。

没有字段设置的响应:

没有。通过代理似乎不是个好主意。如果你只是在想，我在浪费时间，我们把它砍掉吧，那你就不能。div;)
