使用SwiftHTTP库进行HTTP GET请求

Question

需要以下

的帮助

我正在使用SwiftHTTP库并尝试使用savefrom.net获取下载链接

例如，只需访问http://sfrom.net/https://youtube.com/watch?v=war0gHL26ns，网站就会将我们重定向到下载链接

但是，响应的输出不包含下载链接，只包含一长串的javascript函数。

这是我的代码

 var targetURL = "http://sfrom.net/https://youtube.com/watch?v=war0gHL26ns"
 var request = HTTPTask()
     request.requestSerializer = HTTPRequestSerializer()
     request.requestSerializer.headers["Referer"] = "http://en.savefrom.net"

     request.GET(targetURL, parameters: nil, success: {(response: HTTPResponse) in
     if let data = response.responseObject as? NSData {
        let str = NSString(data: data, encoding: NSUTF8StringEncoding)
                println("response: \(str!)") //prints the HTML of the page
         }
     },failure: {(error: NSError, response: HTTPResponse?) in

    })

我没有使用GET，而是尝试了帖子请求，这次模拟点击下载按钮 - http://en.savefrom.net

var postParameters = ["sf_url":"https://youtube.com/watch?v=war0gHL26ns",
        "new":"1"]

    var postURL = "http://en.savefrom.net/savefrom.php"
    var request = HTTPTask()

    request.POST(postURL, parameters: postParameters, success: {(response: HTTPResponse) in
        if let data = response.responseObject as? NSData {
            let str = NSString(data: data, encoding: NSUTF8StringEncoding)
            println("response: \(str!)") //prints the HTML of the page
        }
        },failure: {(error: NSError, response: HTTPResponse?) in

    })

post_output再次返回一长串的javascript函数
