android - Youtube api 400 Bad Request

莫道桑榆晚，为霞尚满天。这篇文章主要讲述android - Youtube api 400 Bad Request相关的知识，希望能为你提供帮助。
YouTube Api发出以下错误，但我在查询中提供了“代码段”，它在调试版中运行良好，而且在我签名的Apk版本中无效

{ "errors" : [ { "domain" : "global", "reason" : "required", "message" : "Required parameter: part", "locationType" : "parameter", "location" : "part" } ], "code" : 400, "message" : "Required parameter: part" }

这是我的查询代码：query = youTube.playlists（）。list（“snippet”）;

query.setKey(getYTkey()); query.setChannelId(con[0].getString(R.string.CHANNEL_ID)); query.setMaxResults((long) 25);
