adb shell ifconfig //查看配置信息
adb shell dumpsys connectivity //查看连接情况
db shell netstat //查看连接状态和地址
adb shell ip ru //查看路由策略
下面展开说一下几个命令输出后的数据如何分析或者查看。
输入命令,获取到如下信息:

上面表示已经打开的连接端口/网卡名称,如果没有打开是看不到的
比如:只有wifi开启状态才显示wlan0这项
这里一般关心wlan0(wifi)和eth0(有线网络)
如果连接成功inet addr会显示具体ip地址
其中inet addr:表示连接成功后的ip地址,如果没有连接成功,是没有的。
这个打印的内容是比较多的,看重点地方即可。
简单的说,就是连接上网络后Current Networks才看到相关信息
ip地址,网络的Score分值(分值越高越优先,一般针对优先网络和wifi的切换)等信息
具体情况如下图如所示:
总结就是注意看Current Networks项里面的内容即可。
部分信息:

我这里是在系统中注释了网络切换后网络释放的操作,所以Current Networks才会有多个网络(正常是只看到一个NetworkAgentInfo网络对象的)
但是系统默认连接的只有一个那就是Active default network的网络
从NetworkAgentInfo也可以体现出现,那就是NetworkRequest的Capabilities包含INTERNET标签;
还有就是 包含REQUEST id=1 这个基本就是当前正在使用的网络
有些设备需要支持wifi和有些网都能连通,就不能释放网络。app内可以进行不同网络的选择连接。
用得不多,可能是查看连接过的具体网址
注意是看上面tcp的信息
Address是本机的信息。
Foreign Address是访问的地址信息。
打印情况如下:

这里是路由策略,应该是和NetworkAgentInfo里面的NetworkRequest有一定的关联
路由策略是可以进行设置的,就是通过adb禁止/允许网络的使用(wifi/有线网络)。
但是路由策略需要root权限!设备默认root或者adb root成功才行。
adb shell ip ru flush //清空所有的路由表
adb shell ip ru add from 192.168.13.X/24 lookup eth0 //把内网设置成以太网
adb shell ip ru add from all lookup wlan0 //添加wifi联网
adb shell ip ru del from XXX //删除某一个路由策略
下面是一组简单的操作示例:
C:\Users\liwenzhi>adb shell ip ru
0: from all lookup local
10000: from all fwmark 0xc0000/0xd0000 lookup legacy_system

可以自己测试一下,删除所有路由策略发现wifi上不了网,把wifi策略添加后就可以上网了。
比较简单易懂在是:
adb shell ifconfig //查看配置信息
比较全面在信息是:
adb shell dumpsys connectivity //查看连接情况
