我正在使用这段代码-：

private static func getJson(_ link: String, completion: @escaping (Json?) -> ()) {
    let url = URL(string: "https://twitter.com/BCCI/status/1476041561288822788?s=20")!
    URLSession.shared.dataTask(with: url) { data, response, error in
        guard let data = data, error == nil else {
            return completion(nil)
        }
        if let json = (try? JSONSerialization.jsonObject(with: data)) as? Json {
            completion(json)
        } else {
            completion(nil)
        }
    }.resume()
}

我想获取json数据并下载链接
