如何在Windows中用Bash脚本启用华为E3372 4G USB网卡移动数据

编辑说明：解决方案可在问题底部查看！

我在Win8.1系统中使用华为E3372 4G USB网卡，该网卡可通过浏览器访问192.168.8.1进入设置页面，手动点击“启用移动数据”按钮开启4G连接。

我尝试用以下脚本自动启用移动数据，但明确知道第4行代码存在问题：

#!/bin/bash

curl -s -X GET "http://192.168.8.1/api/webserver/token" > token.xml
TOKEN=$(grep -v '<?xml version="1.0" encoding="UTF-8"?><response><token>' -v '</token></response>' token.xml)

curl "http://192.168.8.1/api/dialup/mobile-dataswitch" -H "Host: 192.168.8.1" -H "User-Agent: Mozilla/5.0 (Windows NT 6.3; rv:68.0) Gecko/20100101 Goanna/4.8 Firefox/68.0 PaleMoon/29.0.1" -H "Accept: */*" -H "Accept-Language: en-US,en;q=0.5" --compressed -H "Content-Type: application/x-www-form-urlencoded; charset=UTF-8;" -H "_ResponseSource: Broswer" -H "__RequestVerificationToken: $TOKEN" -H "X-Requested-With: XMLHttpRequest" -H "Referer: http://192.168.8.1/html/content.html" -H "Cookie: SessionID=AgVjkIjBxOC0xPbys3nne7rA4I8GXNzUkZCcSOGPR8P3xss8XOuqRbdb0EgHidXhQXZ903xf0nk0F8J81ISqHpZ7kYvZaSW5wHWDqJ9w90pXj90cPwCm7F01fFcmp0gv" -H "Connection: keep-alive" --data-raw "<?xml version=""1.0"" encoding=""UTF-8""?><request><dataswitch>1</dataswitch></request>"

date
exec $SHELL

执行第一个curl命令后，token.xml的内容如下：

<?xml version="1.0" encoding="UTF-8"?><response><token>ZsxY7Q9G90jh4FqUiAjxD9XmqLWf0rYg4RUNf6FoVzeTIlPPms0Ov1RERFFRY77o</token></response>

测试发现，若手动在脚本中填入token，脚本可正常运行：

#!/bin/bash

curl "http://192.168.8.1/api/dialup/mobile-dataswitch" -H "Host: 192.168.8.1" -H "User-Agent: Mozilla/5.0 (Windows NT 6.3; rv:68.0) Gecko/20100101 Goanna/4.8 Firefox/68.0 PaleMoon/29.0.1" -H "Accept: */*" -H "Accept-Language: en-US,en;q=0.5" --compressed -H "Content-Type: application/x-www-form-urlencoded; charset=UTF-8;" -H "_ResponseSource: Broswer" -H "__RequestVerificationToken: ZsxY7Q9G90jh4FqUiAjxD9XmqLWf0rYg4RUNf6FoVzeTIlPPms0Ov1RERFFRY77o" -H "X-Requested-With: XMLHttpRequest" -H "Referer: http://192.168.8.1/html/content.html" -H "Cookie: SessionID=AgVjkIjBxOC0xPbys3nne7rA4I8GXNzUkZCcSOGPR8P3xss8XOuqRbdb0EgHidXhQXZ903xf0nk0F8J81ISqHpZ7kYvZaSW5wHWDqJ9w90pXj90cPwCm7F01fFcmp0gv" -H "Connection: keep-alive" --data-raw "<?xml version=""1.0"" encoding=""UTF-8""?><request><dataswitch>1</dataswitch></request>"

exec $SHELL

我尝试了多种针对同类网卡的方案但均无效，问题显然出在最上方脚本的第4行，希望得到帮助。

感谢您的协助。

===== 编辑说明：已找到解决方案！ =====

markp-fuso的建议为我指明了解决方向。我发现除了每次开关操作都会变化的token外，该网卡还有一个SesTokInfo参数，它不会随开关操作改变（手动测试验证），但插拔网卡可能会使其变化。

以下是经两次测试验证可行的最终脚本：（注：此脚本用于启用移动数据，若要禁用，需将<dataswitch>1</dataswitch>中的1改为0）

#!/bin/bash

curl -s -X GET "http://192.168.8.1/api/webserver/token" > token.xml
curl -s -X GET "http://192.168.8.1/api/webserver/SesTokInfo" > sestoken.xml
TOKEN=$(sed -En 's|.*<token>(.*)</token>.*|\1|p' token.xml)
SESTOKEN=$(sed -En 's|.*<SesInfo>(.*)</SesInfo>.*|\1|p' sestoken.xml)
typeset -p TOKEN
typeset -p SESTOKEN

curl "http://192.168.8.1/api/dialup/mobile-dataswitch" -H "Host: 192.168.8.1" -H "User-Agent: Mozilla/5.0 (Windows NT 6.3; rv:68.0) Gecko/20100101 Goanna/4.8 Firefox/68.0 PaleMoon/29.0.1" -H "Accept: */*" -H "Accept-Language: en-US,en;q=0.5" --compressed -H "Content-Type: application/x-www-form-urlencoded; charset=UTF-8;" -H "_ResponseSource: Broswer" -H "__RequestVerificationToken: $TOKEN" -H "X-Requested-With: XMLHttpRequest" -H "Referer: http://192.168.8.1/html/content.html" -H "Cookie: SessionID=$SESTOKEN" -H "Connection: keep-alive" --data-raw "<?xml version=""1.0"" encoding=""UTF-8""?><request><dataswitch>1</dataswitch></request>"
