iphone - 使用 https 时，它适用于 Android 手机，但在 i-Phone 上收到错误消息：“Error Domain=NSURLErrorDomain Code=-1200”

问题描述

我的视觉工作室 Xamarin.Form 应用程序在 Android 手机中运行良好，但在 iPhone 或 iPhone 模拟器上失败，如下声明：

var content = await _client.GetStringAsync(RI_Url);   // RI_Ur1 is "https://xxxxxxx"

当我将RI_UrlSafari、Chrome 和 Edge 放入时，它可以显示结果。

如果它有效RI_Uri = "http://xxxxxxx"

我试图将以下内容放在 info.plist 中，但它不起作用。

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

有人会帮助解决问题吗？

谢谢。

错误信息是：

解决方案

尝试这个：

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSExceptionDomains</key>
    <dict>
        <key>yoururl</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
        </dict>
    </dict>
</dict>
