Question

我需要在我的应用中创建firebase深层链接，以便使用UIActivityViewController在不同平台上共享它们。为了创建这些链接，我使用以下代码与URLQueryItem获取我将分享给其他应用程序的URL：

func createURLWithComponents(EventToUrl: Event) -> URL? {

    var urlComponents = URLComponents()
    urlComponents.scheme = "https"
    urlComponents.host = "www.example.com"
    urlComponents.path = "/"

    // add params
    let id = URLQueryItem(name: "id", value: EventToUrl.eventID)

    print(EventToUrl.name)
    let name = URLQueryItem(name: "name", value: EventToUrl.name)
    print(name.description)
    print(name.value)
    let photo = URLQueryItem(name: "photo", value:  EventToUrl.photoUrl)
    let created = URLQueryItem(name: "created", value: EventToUrl.creationDate )
    let participants = URLQueryItem(name: "participants", value: String(EventToUrl.Participants.count) )
    let place = URLQueryItem(name: "place", value: EventToUrl.Places[0].name)
    let time = URLQueryItem(name: "time", value: EventToUrl.time[0].TimestampString)
    urlComponents.queryItems = [id, name, photo, created, participants , place , time]

    let dynamicLinkDomain : String = "***.app.goo.gl"
    var deepLink = URLComponents()
    deepLink.scheme = "https"
    deepLink.host = dynamicLinkDomain
    deepLink.path = "/"

    let link = URLQueryItem(name: "link", value:  urlComponents.url?.absoluteString)
    let apn = URLQueryItem(name: "apn", value: "***" )
    let ibi = URLQueryItem(name: "ibi", value: "***" )
    let d = URLQueryItem(name: "d", value: "1")
    deepLink.queryItems = [link, apn, ibi, d]
    print(deepLink.url?.absoluteString)
    print(deepLink.url)

    return deepLink.url
}

这是我发送给他时的链接：

https://***.app.goo.gl/?link=https://www.example.com/?id%3D-KZYfNRCXdSqUG72FmEQ%26name%3Djeremie's%2520Event%26photo%3D%26created%3D%26participants%3D1%26place%3DLa%2520Piazza%26time%3D1482362284.50304&apn=***&ibi=***&d=1

的https：// .app.goo.gl /链接= https://www.example.com/?id%3D-KZYfNRCXdSqUG72FmEQ%26name%3Djeremie＆＃39; S％2520Event％26photo％3D％26created％3D％26participants％3D1％26place％ 3DLa％2520Piazza％26time％3D1482362284.50304＆安培; APN = ＆安培; IBI = ***＆安培; d = 1

如你所见＆＃39;如果事件名称由＆＃34;组成＆＃39; ＆＃34;角色（Jeremie的事件），URLQueryItem没有正确编码这个角色（在我的Android应用程序中，系统函数将其转换为＆＃34;＆＃39;＆＃34; - ＆gt;％27 ）我该如何编码？ PS：我尝试addingPercentEncoding(withAllowedCharacters: .urlFragmentAllowed)没有成功...... 谢谢你的帮助！

我找到了一个比其他解决方案更简单的解决方案。（至少对我而言）

我正常构建了我的URLComponents，但在从它获取url之前，我获取了urlComponents.string并用符号替换了特殊代码。我通过添加PercentEncoding运行该字符串，然后从该字符串中创建一个url。

let stringWithoutBS = urlComponents.string!.replacingOccurrences(of: "%27", with: "'")
        //ignore the force unwrap

guard let encodedURL = stringWithoutBS.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) else {
            print("unhelpful message")
            return nil
        }

var correctURL = URL(string: encodedURL)
