android 8.1 wifi提示“已连接 但无法访问互联网“的解决办法

主要是GFW的问题

adb shell以下命令解决

settings put global captive_portal_detection_enabled 1settings put global captive_portal_mode 1settings put global captive_portal_use_https 0settings put global captive_portal_server connect.settings put global captive_portal_http_url http://connect./generate_204settings put global captive_portal_https_url https://connect./generate_204

注，需要切换飞行模式生效
