Question

我想在Swift 4中通过Alamofire从URL下载文件。我是新手，经过数小时的尝试，我试图找出如何安装Alamofire库，但现在我在代码中遇到了错误。这是代码：

let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory)
        Alamofire.download(
            "http://handasaim.co.il/wp-content/uploads/2018/08/6-9.xls",
            method: .get,
//            parameters: parameters,
            encoding: JSONEncoding.default,
            headers: nil,
            to: destination).downloadProgress(closure: { (progress) in
                //progress closure
            }).response(completionHandler: { (DefaultDownloadResponse) in
                //here you able to access the DefaultDownloadResponse
                //result closure
            })

我得到的错误：

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

我需要对“ info.plist”文件进行哪些更改？

文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

        <string>UIInterfaceOrientationLandscapeLeft</string>
        <string>UIInterfaceOrientationLandscapeRight</string>
    </array>

</dict>
</plist>

如果我的代码不正确，请更正，我还是新手。

谢谢

没事
