Android （CORDOVA）应用程序未在发布模式下连接到套接字api

（注意：这只发生在标签--release上）

问题 我现在建立了一个基于套接字连接的ionic应用程序，当我处于调试模式时，一切正常。。但是，当我移动到release（--release属性）时，应用程序不再连接到api端点。套接字正在发送暂停消息

xhr poll error

预计会发生什么？ 连接到api端点

到底发生了什么？ 未连接到api端点

问询处 我目前正在使用fallowing软件包

看起来在android api级别28之后，除了443之外，您不能使用任何其他端口进行安全连接。。。因为它只会在relase模式下限制您的访问，所以我将套接字端口从原来的443更改为443，并且可以正常工作。

嘿，Razvan，这个问题有帮助吗：
