升级到 Cordova Android 8.0后，尝试连接到http://目标时出现net::ERR_CLEARTEXT_NOT_PERMITTED错误.
After upgrading to Cordova Android 8.0, I am seeing net::ERR_CLEARTEXT_NOT_PERMITTED errors when trying to connect to http:// targets.
那是为什么，我该如何解决?
Why is that and how can I resolve this?
推荐答案
Cordova Android平台中的默认API级别已升级.现在，在Android 9设备上，默认情况下禁用.
The default API level in the Cordova Android platform has been upgraded. On an Android 9 device, clear text communication is now disabled by default.
要再次允许纯文本通信，请将application标记上的android:usesCleartextTraffic设置为true:
To allow clear text communication again, set the android:usesCleartextTraffic on your application tag to true:
<platform name="android">
<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application">
<application android:usesCleartextTraffic="true" />
</edit-config>
</platform>
如注释中所述，如果您之前未定义android XML名称空间，则在构建过程中将收到error: unbound prefix.这表明您需要将其添加到同一config.xml中的widget标签中，如下所示:
As noted in the comments, if you have not defined the android XML namespace previously, you will receive an error: unbound prefix during build. This indicates that you need to add it to your widget tag in the same config.xml, like so:
<widget id="you-app-id" version="1.2.3"
xmlns="http://www.w3.org/ns/widgets"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:cdv="http://cordova.apache.org/ns/1.0">
