// android:usesCleartextTraffic=“true” //要加上这句话啊 允许明文访问,自从Android 6.0(API级别23)开始,Android操作系统默认不允许应用程序使用明文,以增强网络安全性和用户数据的保护。然而,有些应用可能需要连接到不支持HTTPS的旧服务器,或者是在开发过程中需要使用明文传输来方便调试。在这种情况下,开发者可以在应用的AndroidManifest.xml中设置android:usesCleartextTraffic=“true”,这样系统就会允许该应用使用明文。
注意:有些页面在存在跨域请求。要设置允许跨域。还有存储。比如localStorage的存储。允许网络访问等
