soundcloud api - 如何檢查錄製的曲目是否有效？

Question

我該如何檢查錄製的曲目是否已上傳，並且是否已啓用以供嵌入。

我想要顯示音軌的嵌入預覽，一旦上傳完成。

但我在解析url時從scPlayer api得到了404錯誤。

可以跟蹤軌道的可用性的基礎上，我可以使用sCplayer（）

解決的軌道。

任何幫助？

感謝 彼得

我知道在/tracks資源有一個叫state屬性，它可能是你在找什麼。

在他們的文檔中，他們給出的示例值爲finished，因此在軌道準備就緒之前，它可能會讀取​​或processing。注意：我自己沒有嘗試過。

另外，還有可能是另一種價值，像duration或stream_url將讀取NULL，直到軌跡已準備就緒。
