推荐答案

我猜你得到这个是因为 android 改变了它的 http 架构.

I am Guessing that your are getting this because of android changes its http architecture.

要使其在 Android 上运行，请转到您的项目根文件夹.

to make it working on Android go to your project root folder.

yourAppFolder > 资源 > android > xml > network_security_config.xml将您的网络安全配置更改为打击代码.

yourAppFolder > resources > android > xml > network_security_config.xml Change your network security config to blow code.

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network-security-config>
