swift - http APi 请求连接失败，错误 1004

Question

我在 Xcode 中使用 URLSession 和 Swift 从自定义 Api 发出 http 请求时遇到问题。这是我的代码:

let forecast = self.forecastList[forecastIndex]
let url : URL = URL(string: "https:laundryireland.tk/getForecast?pwd=\(self.CustomApiKey)&temp=\(forecast.temp)&hum=\(forecast.humidity)&pres=\(forecast.pressure)&weat=\(forecast.weather)&wind=\(forecast.windspeed)")!
let task = URLSession.shared.dataTask(with: url) {(data, response, error) in
    guard let data = data else { return }
    do {
        let scores = try JSONDecoder().decode(Scores.self, from: data)

            // ...

        } catch {
            print("ops")
        }
    }
task.resume()

此代码已在第三行抛出错误:

我在这里看到:TIC TCP Conn Failed [4:0x604000360300]: 1:61 Err(61) <1> HTTP load failed (error code: -1004错误 1004 与设备无法解析主机有关，但这对我来说似乎很奇怪，因为我的 URL 位于远程服务器上运行的注册域上，可以从任何地方访问该服务器(只需键入: http://laundryireland.tk 在浏览器中查看它是否正常工作)。

如何解决这个问题？

Answer 1

所以问题首先是一个拼写错误:我的域名是 http://laundryireland.tk而在我写的代码中https://laundryireland.tk 。我发现仍然可以更改应用程序设置以允许 http连接:右键单击Info.plist , Open As > Source Code然后将以下代码复制粘贴到<dict>之后在顶部:

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