android 8.1 wifi提示"已鏈接 但沒法訪問互聯網"的解決辦法

主要是GFW的問題

 

adb shell如下命令解決

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

注，須要切換飛行模式生效
