我正在尝试使用 Alamofire 和 Mailgun 发送电子邮件，但无法正常工作。

我正在使用 Mailgun 沙箱并且正确添加了 Alamofire 但是当我运行这段代码时:

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.


    let key = "my correct key"

    let parameters = [
        "Authorization" : "api:my correct key",
        "from": "sender email",
        "to": "destination email",
        "subject": "Test",
        "text": "Testing email send"
    ]

    let r = Alamofire.request(.POST, "https://api.mailgun.net/v3/<my sandbox>/messages", parameters:parameters)
        .authenticate(user: "api", password: key)
        .response { (request, response, data, error) in
            print(request)
            print(response)
            print(error)
    }
    print(r)
}

我得到这个错误日志:

最佳答案

问题在于 Apple 旨在提高安全性的新应用程序传输安全 (ATS) 功能。由于您的应用正在尝试连接到不支持最新 SSL 技术 (TLSv1.2) 的 HTTP 服务器 (api.mailgun.net)，因此 ATS 会导致您的连接失败并出现此类错误。我遇到了同样的问题。

请参阅本文:http://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/

如果您不想阅读它，只需右键单击您的 info.plist，选择“打开方式”->“源代码”，然后将其粘贴到最后一个 <\dict> 之前。

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>api.maillgun.net</key>
    <dict>
      <!--Include to allow subdomains-->
      <key>NSIncludesSubdomains</key>
      <true/>
      <!--Include to allow HTTP requests-->
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
      <!--Include to specify minimum TLS version-->
      <key>NSTemporaryExceptionMinimumTLSVersion</key>
      <string>TLSv1.1</string>
    </dict>
  </dict>
</dict>
