NSURLSession/NSURLConnection HTTP 加载失败 (kCFStreamErrorDomainSSL, -9843) - Mac OS 应用

Question

当我尝试将我的 Swift Mac OS 应用程序连接到在我的本地主机上的服务器上运行的页面时，我收到此错误。我已确保服务器已启动并正在运行。
这是我的 info.plist 文件：

这是尝试访问页面的代码部分。它来自 swift 应用程序。构建项目时没有错误。我不能使用 NSURL，因为这个版本的 Swift 没有 NSUrl，它被更改为 URLSession、URLRequest 等等：

 private func sendtoPHP(nSt : NetworkStatistics,lat : Double, long : Double )
    {
        var request = URLRequest(url: URL(string: "https://17.83.148.252/test.php")!)
        request.httpMethod = "POST"

//        let postString = "a=\(nSt.getCurrentSsid()!)&b=\(nSt.getRssiValue()!)&c=\(nSt.getNoiseMeasurement()!)&d=\(nSt.getWlanChannel()!)&e=\(nSt.getBssid()!)&f=\(nSt.getCountryCode()!)&g=\(nSt.getHardwareAddress()!)&h=\(nSt.getTransmitPower()!)&i=\(lat)&j=\(long)"

        let postString = "a=\(nSt.getCurrentSsid()!)"
        request.httpBody = postString.data(using: .utf8)
        let task = URLSession.shared.dataTask(with: request) { data, response, error in
            guard let data = data, error == nil else {                                                 // check for fundamental networking error
                print("error=\(error)")
                return
            }
            if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {           // check for http errors
                print("statusCode should be 200, but is \(httpStatus.statusCode)")
                print("response = \(response)")
            }

            let responseString = String(data: data, encoding: .utf8)
            print("responseString = \(responseString)")
        }
        task.resume()
    }

我尝试用 localhost 替换 17.83.148.252 但它不起作用。
以下是详细的错误描述：

是的，我已经尝试过了。请查看我的 info.plist，密钥 NSAppTransportSecurity 在那里。我找到了解决方案。问题是，我使用 Mac OS 服务器在服务器中运行 PHP 文件。有趣的是，当我运行 localhost/test.php 时，它在浏览器中运行，但不是从我的 swift 程序（在同一台机器上）中运行。我在代码中使用了这个链接：https://username-macbook-air.local/test.php 而不是https://localhost/test.php。好像，当我使用 localhost 时，访问被阻止说“服务器没有证书”，即使我包括：

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSExceptionDomains</key>
        <dict>
            <key>localhost</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSExceptionRequiresForwardSecrecy</key>
                <false/>
                <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
                <true/>
                <key>NSTemporaryExceptionMinimumTLSVersion</key>
                <string>TLSv1.1</string>
            </dict>
        </dict>
    </dict>

所以我认为 OS X 中的 Swift 3 需要与 SSL 证书的安全连接，默认情况下存在 SSL 证书，但我们只需要找到正确的链接。
