如何删除带有特殊字符的 NSURL 的最后一个路径

Question

所以我有点困惑。我有一个像这样的 NSURL

https://something/something/test#4.html

我想删除最后一条路径。我尝试使用 URLByDeletingLastPathComponent 方法，但结果是这样。

https://something/something/#4.html

我希望最终结果如下。

https://something/something

Answer 1

首先你必须删除片段。然后最后一个路径使用deletingLastPathComponent().

var url = URL(string: "https://something/something/test#4.html")

if let fragment = url?.fragment{
    url = URL(string: (url?.absoluteString.replacingOccurrences(of: "#\(fragment)", with: ""))!)
    url = url?.deletingLastPathComponent()
}

print(url!)

Answer 2

删除片段的聪明方法是URLComponents

let url = URL(string: "https://something/something/test#4.html")!

if var urlComponents = URLComponents(url: url, resolvingAgainstBaseURL: false) {
    urlComponents.fragment = nil
    let trimmedURL = urlComponents.url!.deletingLastPathComponent()
    print(trimmedURL)
}
