【问题描述】：

我想在 Swift 4 中通过 Alamofire 从 URL 下载文件。 我是 swift 新手，经过数小时尝试找出如何安装 Alamofire 库，现在我在代码中遇到错误。 代码如下：

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">

    <array>
        <string>UIInterfaceOrientationPortrait</string>
        <string>UIInterfaceOrientationPortraitUpsideDown</string>
        <string>UIInterfaceOrientationLandscapeLeft</string>
        <string>UIInterfaceOrientationLandscapeRight</string>
    </array>

</dict>
</plist>

如果我的代码不好请纠正，我还是个新手。

谢谢，

【参考方案1】：

添加您的 plist 文件并解决问题 :) “Swift 4”

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

【讨论】：

谢谢！你知道如何使用这个文件（它在哪里下载的？）

现在是最难的部分，解析和显示表格中的数据。你可以找到相关的例子。

您应该只允许来自您实际需要的 URL 的不安全加载，而不是全部。
