iOS流视频从谷歌驱动器Swift

Question

我正在构建一个iOS应用程序，来自Google的Stream视频驱动视频链接如下所示

html" target="_blank">https://drive.google.com/file/d/0B2Kri7-TaAFJSlJ4UTJuSElGamM/preview

从上面的URL获取流链接的唯一方法是解码webView超文本标记语言

let myURLString = "https://drive.google.com/file/d/0B2Kri7-TaAFJSlJ4UTJuSElGamM/preview"

    if let myURL = NSURL(string: myURLString) {

        do {
            let myHTMLString = try String(contentsOfURL: myURL, encoding: NSUTF8StringEncoding)
            print("HTML : \(myHTMLString)")

        } catch {
            print("Error : \(error)")
        }
    } else {
        print("Error: \(myURLString) doesn't  URL")
    }

之后，我得到了webView的超文本标记语言

问题是：

我在超文本标记语言中寻找的是这个“fmt_stream_map”，它包含了我也需要的所有流式链接流式传输视频，但我不知道如何访问它并从中获取蒸汽链接。

PS：我正在与一位Android开发人员合作，他告诉我他使用这种方法来解决问题，但他无法向我解释，我也不懂java

我使用以下方法修复了问题：

        let myURLString = "https://drive.google.com/file/d/0B1XhqDeOfqG7UWZSaG1ZbFFhSzQ/preview"

    if let myURL = NSURL(string: myURLString) {

        do {
            let myHTMLString = try String(contentsOfURL: myURL, encoding: NSUTF8StringEncoding)

            let t = myHTMLString

            if let rangeOfZero = t.rangeOfString("plid", options: NSStringCompareOptions.BackwardsSearch) {

                let suffix = String(t.characters.suffixFrom(rangeOfZero.endIndex))

                //    print(suffix)

                let input = "\(suffix)"
                let detector = try! NSDataDetector(types: NSTextCheckingType.Link.rawValue)
                let matches = detector.matchesInString(input, options: [], range: NSRange(location: 0, length: input.utf8.count))

                //  print(matches)
                for match in matches {

                    let url = (input as NSString).substringWithRange(match.range)

                    linksA.append(url)

                }

                theLink()

            } else {
                print("noooo")
            }
        } catch {
            print("Error : \(error)")
        }
    } else {
        print("Error: \(myURLString) doesn't  URL")
    }

之后，您需要使用此方法解码流式链接：

    func theLink() {


    /// /[u]00../g


    let firstElement = linksA.first

    let t = firstElement!.stringByReplacingOccurrencesOfString(",35", withString: "")

    let deUrl = t.characters.split{$0 == "|"}.map(String.init)

    let link = deUrl[0]

    // the link needs to be decoded

    let i = link.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)


    let p = i!.stringByReplacingOccurrencesOfString("%5Cu", withString: "")


    // you can see how the link should look like here :
    // http://ddecode.com/hexdecoder/?results=d82d4e564eccc1a6b96ee7c5c1e1c3b2

    // %252C : ,
    // 003d : =
    // 0026 : &

     let re = p.stringByReplacingOccurrencesOfString("003d", withString: "=")
     let y = re.stringByReplacingOccurrencesOfString("0026", withString: "&")
        let c = y.stringByReplacingOccurrencesOfString("%252C", withString: ",")

    print(c) }
