Question

当我尝试将Swift Mac OS应用程序连接到我的localhost上的服务器上运行的页面时，我收到此错误。我确保服务器已启动并运行这是我的info.plist文件：

这是尝试访问该页面的代码的一部分。它来自迅捷的应用程序。构建项目时没有错误。我无法使用NSURL，因为此版本的Swift没有NSUrl，它已更改为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说明：

是的我已经尝试过了。请查看我的info.plist，关键的NSAppTransportSecurity就在那里。我找到了解决方法。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，它是从浏览器工作但不是从我的swift程序（在同一台机器上）。我在我的代码中使用了这个链接：https://username-macbook-air.local/test.php而不是{{3} }。似乎，当我使用localhost时，访问被阻止说＆＃34;服务器没有证书＆＃34; ，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证书建立安全连接，默认情况下我们必须找到正确的链接。
