ionic cordova build android/ios --prod --debug
ionic serve
两条命令都可以访问自己生成的CA证书。
但是生成release版本时发现无法访问。
针对已经CA认证过的HTTPS无需做修改。但是第三方生成的需要在工程中做以下修改：

android

cordova v4及以下
project/platforms/android/CordovaLib/src/org/apache/cordova/CordovaWebViewClient.java
cordova v5
project/platforms/android/CordovaLib/src/org/apache/cordova/engine/SystemWebViewClient.java

public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
  final String packageName = this.cordova.getActivity().getPackageName();
  final PackageManager pm = this.cordova.getActivity().getPackageManager();
 
  ApplicationInfo appInfo;
  try {
    appInfo = pm.getApplicationInfo(packageName, PackageManager.GET_META_DATA);
    if ((appInfo.flags & ApplicationInfo.FLAG_DEBUGGABLE) != 0) {
      // debug = true
      handler.proceed();
      return;
    } else {
      // debug = false
      // THIS IS WHAT YOU NEED TO CHANGE:
      // 1. COMMENT THIS LINE
      // super.onReceivedSslError(view, handler, error);
      // 2. ADD THESE TWO LINES
      // ---->
      handler.proceed();
      return;
      // <----
    }
  } catch (NameNotFoundException e) {
    // When it doubt, lock it out!
    super.onReceivedSslError(view, handler, error);
  }
}

ios

project/platforms/ios/Project/Classes/AppDelegate.m
添加：
@implementation NSURLRequest(DataController)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
    return YES;
}
