url 在 iOS 中解码的问题

Question

我正在尝试解码具有另一个 url（单独编码）作为查询参数的 url：

com.testScheme://openurl?url=https%3A%2F%2Fm%2Euber%2Ecom%2Ful%3Faction%3DsetPickup%26pickup%3Dmy%5Flocation%26dropoff%5Bformatted%5Faddress%5D%3D5394%2520General%2520Hood%2520Trl%2C%2520Nashville%2520TN

然而，下面的代码似乎是"double decoding"两次编码url。

guard let urlComponents = URLComponents(url: url, resolvingAgainstBaseURL: false),
    let requestType = urlComponents.host else {
       return false
}

if requestType.lowercased() == "openurl" {
    guard let queryItems = urlComponents.queryItems,
        let urlString = queryItems.filter({ [=13=].name == "url" }).first?.value?.removingPercentEncoding,
        let url = URL(string: urlString) else {
        //unable to get parameters
        return false
    }

    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + DispatchTimeInterval.milliseconds(25)) {
        UIApplication.shared.openURL(url)
    }            

    return true
}

urlString 的输出：

https://m.uber.com/ul?action=setPickup&pickup=my_location&dropoff[formatted_address]=5394 General Hood Trl, Nashville TN

我需要urlString成为：

https://m.uber.com/ul?action=setPickup&pickup=my_location&dropoff[formatted_address]=5394%20General%20Hood%20Trl,%20Nashville%20TN

为什么会出现 "double decoding"，我该如何解决？

Answer 1

尝试从下面的行中删除 removingPercentEncoding

let urlString = queryItems.filter({ [=10=].name == "url" }).first?.value?.removingPercentEncoding
