一、cURL安装

　　登录OpenWrt的Web管理后台，选择 “系统->Software（软件）”菜单，在 “Filter” 中输入cURL，在软件列表中，选择名为 “curl” 的应用进行安装（图14）。注：若搜索不到任何软件，请先在 “操作” 中点击 “Update lists”，来更新软件列表。更新时，需确保OpenWrt能正确访问广域网，即：在 “网络->接口” 中，至少需要有一个接口能成功连接至广域网。

图14 cURL软件安装

 二、cURL认证请求捕获

　　通过cURL，可以模拟浏览器发送请求给服务器，完成宽带账户认证登录的过程。首先，需要捕获浏览器发送给服务器的请求，然后使用cURL方法模拟发送。

1. 捕获浏览器认证请求

　　1）仅启用一个虚拟macvlan接口：在OpenWrt的Web面板中，进入 “网络-> 负载均衡（load balancing）” 菜单，选择 “接口” 选项卡，在接口列表中，编辑各接口，仅保留一个接口作为后续捕获认证登录数据包所用，禁用其余接口，防止宽带登录完毕后OpenWrt通过负载均衡切换至其他出口，影响调试。

　　2）打开浏览器（建议使用Chrome），访问宽带认证登录网页。

　　3）按键盘的F12按键，打开开发者调试工具。

　　4）选择 “Network” 选项卡（图15），在这里，可以看到浏览器与服务器的交互请求。首先，点击左上角Clear按钮（图15 开发者调试工具的左上角红框处），清空现有请求（若已经为空则不需清空）。

图15 浏览器开发者调试工具

 　　5）完成准备后，输入用户名和密码，点击登录按钮，完成所有登录流程。此时，可以在开发者调试工具中，看到登录请求数据。在该条数据处单击右键，选择 “Copy -> Copy as cURL (bash)”，图16。说明：bash形式的cURL可以在Linux（如OpenWrt）终端或Shell脚本中执行，cmd形式的cURL可以在Windows系统的命令提示符（cmd）中执行。

图16 捕获浏览器登录认证请求

 　　6）将复制的cURL请求，粘贴至文本文件中。例如本次实验捕获的认证数据如下所示。

curl 'http://10.255.255.34/api/v1/login' \
  -H 'Connection: keep-alive' \
  -H 'Accept: application/json, text/plain, */*' \
  -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.82 Safari/537.36' \
  -H 'Content-Type: application/json;charset=UTF-8' \
  -H 'Origin: http://10.255.255.34' \
  -H 'Referer: http://10.255.255.34/authentication/login' \
  -H 'Accept-Language: zh-CN,zh;q=0.9' \
  --data-raw '{"username":"**********5","password":"******","channel":"3","ifautologin":"0","pagesign":"secondauth","usripadd":"10.12.57.76"}' \
  --compressed \
  --insecure

2. 编辑浏览器认证请求

　　1）对捕获的浏览器认证请求，去除末尾的下列两行，并去除这两行的上一行末尾的换行符 “\”。

--compressed \
--insecure

　　去除后完整请求如下所示：

curl 'http://10.255.255.34/api/v1/login' \
  -H 'Connection: keep-alive' \
  -H 'Accept: application/json, text/plain, */*' \
  -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.82 Safari/537.36' \
  -H 'Content-Type: application/json;charset=UTF-8' \
  -H 'Origin: http://10.255.255.34' \
  -H 'Referer: http://10.255.255.34/authentication/login' \
  -H 'Accept-Language: zh-CN,zh;q=0.9' \
  --data-raw '{"username":"**********5","password":"******","channel":"3","ifautologin":"0","pagesign":"secondauth","usripadd":"10.12.57.76"}'

　　2）以root账户登录OpenWrt终端（可直接本机登录，或采用SSH等方式登录）。复制上述编辑完毕的cURL请求文本，粘贴至OpenWrt终端内，回车运行。运行完毕后可看到服务器返回的登录成功数据，本实验的数据如（图17）。

图17 终端执行结果

三、编写Shell脚本

　　Shell脚本将模拟人工启用/禁用接口、认证登录的行为，对每一个MWAN3接口依次启用，并关闭其余接口，完成该接口对应的macvlan虚拟网卡认证登录。完成所有macvlan虚拟网卡认证登录后，再开启所有的MWAN3接口，即可通过各接口进行负载均衡。

1. 准备工作（grep筛选IP、awk修改配置文件）

　　从捕获的cURL认证请求中，可以看到请求参数还需要网卡的IP地址（不同的认证页面需要的参数也不一样，如有的可能还需要网卡MAC地址，有的只需要账号密码），因此需准备好各虚拟macvlan网卡的IP地址。网卡的IP地址可通过OpenWrt的Web管理页面，选择 “网络->接口” 菜单，在对应的接口（如wan0）处，可查看到网卡的IPv4地址。此处，我们需要在终端中，通过命令方式获取网卡IP。

　　1）查看网卡信息

　　在OpenWrt终端内，输入 ifconfig 命令可查看所有网卡信息。

　　输入 ifconfig vth0 命令可查看单一网卡信息（如vth0），结果如（图18）。第一个红框为vth0的MAC地址，第二个红框为vth0的IPv4地址。

图18 查看网卡信息

 　　2）筛选出IPv4地址

　　通过命令 grep "text"，可筛选出具有 “text” 文本所在的行。

　　通过 cut -d '分隔符' -f 显示字段 命令，可以显示文本中的指定字段的内容。如执行命令：

echo "a/b/c" | cut -d '/' -f 2

　　echo 表示输出后面的结果，cut -d '/' 表示以符号 / 作为分隔符，将字符串 a/b/c分割为a、b、c三个字段，-f 2 表示显示第二个字段，即字符b。因此返回结果为b。

　　综上所述，结合 ipconfig 查询的网卡信息格式（图18），使用下列命令可获取指定网卡的IPv4地址（图19）。

ifconfig vth0 |grep 'inet addr:'|cut -d ' ' -f 12|cut -d ':' -f 2
图19 筛选IPv4地址

　　若认证信息还需MAC地址，可自行编写命令获取。

　　3）准备MWAN3接口的启用/停止命令

　　MWAN3配置文件位于：/etc/config/mwan3，在终端内使用下列命令查看MWAN3配置文件。

vim /etc/config/mwan3

　　打开MWAN3配置文件后，可查看配置文件（图20）。其中，config interface 为接口配置章节，每个接口均对应一个 config interface。接下来的 option … 为接口章节对应的各配置选项，重点关注 option enabled 选项。通过修改该选项的值为 “1” 或 “0”，便可开启或关闭MWAN3接口。

图20 MWAN3配置文件解读

　　使用awk函数编写Shell脚本，实现自动定位到各接口，然后开启该接口，并关闭其余接口的功能。当某个接口唯一打开后，便可采用cURL方法为该接口登录网页认证账户。

       使用下列命令，便可自动寻找到wan0的章节位置，并在该章节下寻找到enabled的配置选项，自动将0替换为1后，保存至文件。对于其他接口，仅需将命令中第一行的 'wan0' 替换为对应mwan3接口的名字即可。第四行 gsub(0,1) 用于将0替换为1，若需要关闭接口将其改为gsub(1,0)即可。

awk -F "'" -v section="config interface 'wan0'" '
    $0==section{flag=1;print;next}
    /config/{flag=0}
    flag==1&&/option enabled/{gsub(0,1)}
    {print}' /etc/config/mwan3 1<>/etc/config/mwan3

　　更改配置文件后，需要使用下列命令重启服务。

/etc/init.d/mwan3 restart

【详细解释】awk函数使用说明

  • awk语句中，单引号部分为执行的指令部分，前面为参数设置，后面为文件操作。
  • -F参数：分隔符参数。默认分隔符为空格。此处指定为单引号。

　　例如一文件，内有字符串：option enabled '1'

　　使用 awk -F "'" '{print $0;print $1;print $2}' 文件名 命令后，可按单引号将上述字符串分割开。在awk内，变量$0为完整字符串，$1为第一部分，即 option enabled；$2为第二部分，即1。

  • -v 参数：可指定自定义变量。如 -v section="config interface 'wan0'"，在执行的指令部分即可使用 section 变量来表达 config interface 'wan0'。
  • 指令部分：-v参数后面的单引号部分为执行的指令部分。此处一共有四段指令。awk将对文件逐行执行各个指令。指令中，{} 内为执行的操作，{} 前面为该操作的条件。

　　其中，next 表示立即跳转至下一行。即：忽略后面剩下的指令，立即跳转至下一行。在本例中，当 $0==section 匹配满足后，即寻找到了wan0接口的章节，将flag置1后，立即执行下一行。这样可避免下一段内使用正则表达式 /config/ 指令再次匹配到 config interface ‘wan0’ 所在的行，而又将flag立刻置为0。正确的操作应该是 /config/ 匹配到下一章开头时，再将flag置0。

　　flag为1的区间，即为wan0所在的配置选项范围。在此范围内继续匹配 option enabled 选项即可。匹配到flag为1且 option enabled 后，使用 gsub()，即可将0替换为1。然后将修改结果输出至文件即可。

2. 编写Shell脚本

　　1）编写一个虚拟macvlan网卡（如vth0）的Shell脚本。

FILEDIR=/etc/config/mwan3
# Open only one mwan interface.
awk -F "'" -v section="config interface 'wan0'" '
    $0==section{flag=1;print;next}
    /config/{flag=0}
    flag==1&&/option enabled/{gsub(0,1)}
    {print}' $FILEDIR 1<>$FILEDIR
awk -F "'" -v section="config interface 'wan1'" '
    $0==section{flag=1;print;next}
    /config/{flag=0}
    flag==1&&/option enabled/{gsub(1,0)}
    {print}' $FILEDIR 1<>$FILEDIR
awk -F "'" -v section="config interface 'wan2'" '
    $0==section{flag=1;print;next}
    /config/{flag=0}
    flag==1&&/option enabled/{gsub(1,0)}
    {print}' $FILEDIR 1<>$FILEDIR
awk -F "'" -v section="config interface 'wan3'" '
    $0==section{flag=1;print;next}
    /config/{flag=0}
    flag==1&&/option enabled/{gsub(1,0)}
    {print}' $FILEDIR 1<>$FILEDIR
awk -F "'" -v section="config interface 'wan4'" '
    $0==section{flag=1;print;next}
    /config/{flag=0}
    flag==1&&/option enabled/{gsub(1,0)}
    {print}' $FILEDIR 1<>$FILEDIR
awk -F "'" -v section="config interface 'wan5'" '
    $0==section{flag=1;print;next}
    /config/{flag=0}
    flag==1&&/option enabled/{gsub(1,0)}
    {print}' $FILEDIR 1<>$FILEDIR
awk -F "'" -v section="config interface 'wan6'" '
    $0==section{flag=1;print;next}
    /config/{flag=0}
    flag==1&&/option enabled/{gsub(1,0)}
    {print}' $FILEDIR 1<>$FILEDIR
awk -F "'" -v section="config interface 'wan7'" '
    $0==section{flag=1;print;next}
    /config/{flag=0}
    flag==1&&/option enabled/{gsub(1,0)}
    {print}' $FILEDIR 1<>$FILEDIR
/etc/init.d/mwan3 restart

# Get the IP address of the current network card.
CUIP=$(ifconfig vth0 |grep 'inet addr:'|cut -d ' ' -f 12|cut -d ':' -f 2)

# Log in through curl. This part is the general code of vth0 ~ vth7.
NStat=$(curl 'http://10.255.255.34/api/v1/login' \
  -H 'Connection: keep-alive' \
  -H 'Accept: application/json, text/plain, */*' \
  -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.82 Safari/537.36' \
  -H 'Content-Type: application/json;charset=UTF-8' \
  -H 'Origin: http://10.255.255.34' \
  -H 'Referer: http://10.255.255.34/authentication/login' \
  -H 'Accept-Language: zh-CN,zh;q=0.9' \
  --data-raw '{"username":"**********5","password":"******","channel":"3","ifautologin":"0","pagesign":"secondauth","usripadd":"'$CUIP'"}')

# Judge whether the login is successful.
echo "${NStat}"
NCode=$(echo "${NStat}" | grep "code" | cut -d " " -f 2 | cut -d "," -f 1)
if [ $NCode != 200 ]; then
    # Login failed.
    vth0ISP=0
else
    vth0ISP=1
fi

　　行1~行43：启用vth0的接口，禁用vth1~vth7接口。

　　行45~46，获取vth0网卡的IP地址，并保存至CUIP变量。

　　行48~57，执行cURL请求，并将服务器返回结果存储至NStat变量。注意：需在捕获的cURL外，加入$()来获取返回的字符串结果。还需将请求中的IP地址替换为CUIP变量，变量读取方法为$CUIP。

　　行59~67，根据图17，自行编写返回结果筛选代码，此处筛选返回的状态参数code，经测试，本实验的code为200时表明登录成功。

　　登录成功后vth0ISP变量置1，在所有接口开启完毕后，将会逐个判断vth*ISP变量，若为1则启用对应接口，否则禁用对应接口。脚本执行完毕后，登录OpenWrt后台，转到 “网络->负载均衡” 页面，选择 “接口” 选项卡，查看各接口的启用状态即可知道哪些接口认证登录失败。

　　2）编写完整的Shell脚本

　　将上述Shell脚本复制，并修改行1~行43的启用接口和禁用接口，修改行46的网卡名称，修改行48~57中的宽带账户和密码，修改行64、66的标志变量名称即可。

　　完整的参考脚本见文末。

　　在最后，加入如下代码，开启所有成功认证登录的接口。

3. 保存Shell脚本

　　1）脚本文件创建

　　在OpenWrt终端内，运行如下命令，将脚本文件创建在/etc/config文件夹下（也可自行选择保存路径）。

vim /etc/config/nw_log.bash

　　按键盘按键 “i”，进入编辑状态，将上述完整的Shell脚本输入或粘贴至脚本文件内。注意：需要在脚本最顶部插入一行作为第一行，输入下列脚本解释器声明代码。

#!/bin/bash

　　编辑完毕后，按键盘按键 “ESC”，退出编辑状态。并输入如下代码后按回车按键，保存并关闭文件。

:wq

　　2）为Shell脚本赋予执行权限

　　在OpenWrt终端内，运行如下命令。

chmod +x /etc/config/nw_log.bash

4. 执行Shell脚本

　　在OpenWrt终端内，运行如下命令。

sh /etc/config/nw_log.bash

四、开机自动执行Shell脚本

　　登录OpenWrt的Web管理面板，选择 “系统->启动项” 菜单，并切换至 “本地启动脚本” 选项卡。在exit 0 上方，输入如下代码并点击右下角保存按钮。

sleep 10

# Log in to the network.
sh /etc/config/nw_log.bash

　　sleep 10 为延迟10s再执行，开机后各接口将注册并启用，此处的延时可以等待各接口成功从服务器获取到IP地址，对于需要IP地址来认证登录宽带账户的请求而言非常重要。

　　重启服务器，可以在 “网络->负载均衡” 的 “接口” 选项卡下，可以看到成功认证登录的接口为启用状态。

附录、完整的Shell认证登录脚本代码

 　　【提示】采用数组等结构，可以实现部分代码的复用，简化代码结构。但系统本身的Shell脚本不具备数组这类结构，需查找资料另行安装配置。

　　【注意】不同的网页登录认证页面，所发送的登录请求也不一样。代码仅供参考，您至少需要理解代码 并 自行修改运营商标识NClass、awk命令、cURL请求代码 才能正常使用。
