const urlObj = new window.URL( validUrlString );
urlObj.hostname
// Error: URL.hostname is not implemented

|

const urlObj = new window.URL( validUrlString );
urlObj.hostname
// Error: URL.hostname is not implemented

如何重现问题？

const urlObj = new window.URL( validUrlString );
urlObj.hostname
// Error: URL.hostname is not implemented
