我对您的其他问题-我认为您使用API​​的方式没有任何问题本身，但是您不能裁剪''。使用另一个问题中给出的解决方案。或者，也许您可​​以更多地解释您要做什么。

I partially answered in my answer to your other question - I don't see anything wrong with how you are using the API itself, however you cannot tailor "''". Use the solution given in the other question. Or, maybe you can explain a bit more about what you are trying to do.
