SAPUI5 Cordova iOS 应用程序 Ajax 调用不起作用（无限挂起）

Question

我目前正在为 iOS 构建一个 SAPUI5 Cordova 应用程序。我正在使用 Cordova 8、iOS 11.0.3 和 xcode 9.2 问题是我的 Ajax 调用似乎都没有工作（它们无限期挂起，甚至没有返回错误代码）。这似乎是一个常见问题，因为已经有很多围绕这个问题的线程，但是这些线程中提出的解决方案似乎都不适用于我的应用程序。 到目前为止，我已经尝试了以下方法：

在 index.html 的 meta 标签中设置 CSP：

<meta http-equiv="Content-Security-Policy" content="default-src * data: gap: https: 'unsafe-inline' 'unsafe-eval'; style-src 'unsafe-inline' *; media-src * 'unsafe-inline'; connect-src * 'unsafe-inline'" />

在 xcode 项目的 info.plist 文件中设置 App Transport Security 设置：

导入cordova-whitelist-plugin并设置访问源、allow-intent和allow-navigation到*：

<?xml version='1.0' encoding='utf-8'?>
<widget id="opensap.myapp.eventapp" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
<name>eventapp2</name>

关于如何让它发挥作用的任何提示或建议？

编辑：尝试在域级别设置异常，但这也不起作用：

尝试将被叫域添加到您的 info.plist 在 Exception domain 部分并禁用 CertificateTransparency，并设置 TLS1.0。

  <key>NSAppTransportSecurity</key>
    <dict>
        <key>NSExceptionDomains</key>
        <dict>
            <key>yourdomain.com</key>
            <dict>
                <key>NSExceptionAllowsInsecureHTTPLoads</key>
                <true/>
                <key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key>
                <true/>
                <key>NSExceptionRequiresForwardSecrecy</key>
                <false/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                <false/>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSExceptionMinimumTLSVersion</key>
                <string>TLSv1.0</string>
                <key>NSRequiresCertificateTransparency</key>
                <false/>
            </dict>
        </dict>
    </dict>
