Android webview在新Android版本上发布表单问题

我在测试过的Android版本2.3.6-4.2.2上有一个工作场景。

首先，我手动将 html 字符串设置为 WebView，这将打开一个新网页。

但是，在 Android 4.4.2 和 5.0 上，Webview 会返回有关 SSL 证书的错误。这些版本有什么区别？

.HTML：

      <form name="downloadForm"      action="https://asdasd/sds/sds"            method="POST">

我还添加了来自 LogCat 的日志：

从KitKat到更高版本的webview是基于Chromium而不是Android的特定分支Webkit。
