我们一步一步来。
概述
要使用HttpHelper框架重启路由器,我们需要先了解什么是HttpHelper框架和路由器重启的过程。
HttpHelper框架是一个基于.NET Framework的HTTP请求框架,可以帮助我们实现请求数据、提交数据、模拟浏览器,进而实现网络爬虫等多种功能。而路由器重启,则是通过模拟客户端向路由器发送重启指令,实现路由器远程重启的过程。
下面我们将依次介绍如何通过C#和HttpHelper框架来实现路由器重启。
步骤
1. 引用HttpHelper框架
我们需要先引用HttpHelper框架,可以通过NuGet包管理器来安装。在Visual Studio的“工具”菜单中选择“NuGet包管理器”,搜索HttpHelper,选择合适的版本并安装即可。
2. 获取路由器登录页
在重启路由器之前,我们需要先获取到路由器的登录页。通常情况下,路由器的登录页地址为192.168.1.1或192.168.0.1,可以通过ping命令或浏览器输入地址来获取。获取到登录页后,我们需要通过HttpHelper框架来模拟浏览器,获取正确的登录状态和Session信息。
HttpItem item = new HttpItem()
{
URL = "http://192.168.1.1", // 登录页地址
Method = "get",
Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
ContentType = "text/html",
};
HttpHelper httpHelper = new HttpHelper();
HttpResult result = httpHelper.GetHtml(item);
string html = result.Html;
string url = result.ResponseUri.ToString();
string cookie = result.Cookie;
3. 获取登录状态和Session信息
获取到登录页之后,我们需要填写正确的用户名和密码,登录到路由器后台管理界面。这个过程需要提交表单数据,并把Session信息存储到HttpHelper中,方便后续操作。
HttpItem item = new HttpItem()
{
URL = url, // 登录页地址
Method = "post",
Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
ContentType = "application/x-www-form-urlencoded",
Postdata = string.Format("username={0}&psd={1}&login=%B5%C7%C2%BC", "admin", "admin"), // 登录表单数据,需要根据实际情况修改
Cookie = cookie, // 登录状态和Session信息
};
HttpHelper httpHelper = new HttpHelper();
HttpResult result = httpHelper.GetHtml(item);
4. 重启路由器
在获取到正确的Session信息后,我们就可以通过模拟发送重启指令的方式,重启路由器了。这个过程需要向路由器发送POST请求,提交正确的表单数据。
string routerURL = "http://192.168.1.1/cgi-bin/luci";
string postData = "cbi.submit=1&cbi.apply=1&cbi._=1610433931773&action=reboot&dummy=50724";
string referer = "http://192.168.1.1/cgi-bin/luci/admin/system";
HttpItem item = new HttpItem()
{
URL = routerURL, // 路由器重启地址
Method = "post",
ContentType = "application/x-www-form-urlencoded",
Accept = "application/json, text/javascript, */*; q=0.01",
Referer = referer,
Cookie = cookie, // 登录状态和Session信息
Postdata = postData, // 重启指令数据,需要根据实际情况修改
};
HttpHelper httpHelper = new HttpHelper();
HttpResult result = httpHelper.GetHtml(item);
在以上几步操作完成后,路由器就会收到重启指令,并开始执行路由器重启的过程。
示例说明
以下是两条示例说明,帮助我们更好地理解如何使用HttpHelper框架重启路由器。
示例1:TP-Link路由器重启
TP-Link路由器的登录页是http://192.168.0.1,假设用户名和密码都是admin。那么重启流程如下:
- 访问http://192.168.0.1,获取正确的登录状态和Session信息。
- 提交登录表单数据,进入路由器后台管理页面。
- 访问http://192.168.0.1/cgi-bin/luci,获取正确的Session信息。
- 提交重启指令数据,触发路由器重启。
其中,第3步是TP-Link路由器特有的,必须获取正确的Session信息才能发送重启指令。
代码实现如下:
// 获取登录状态和Session信息
HttpItem item1 = new HttpItem()
{
URL = "http://192.168.0.1",
Method = "get",
Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
ContentType = "text/html",
};
HttpHelper httpHelper1 = new HttpHelper();
HttpResult result1 = httpHelper1.GetHtml(item1);
string html1 = result1.Html;
string url1 = result1.ResponseUri.ToString();
string cookie1 = result1.Cookie;
HttpItem item2 = new HttpItem()
{
URL = url1,
Method = "post",
Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
ContentType = "application/x-www-form-urlencoded",
Postdata = string.Format("username={0}&password={1}&action={2}", "admin", "admin", "login"),
Cookie = cookie1,
};
HttpHelper httpHelper2 = new HttpHelper();
HttpResult result2 = httpHelper2.GetHtml(item2);
// 获取正确的Session信息
HttpItem item3 = new HttpItem()
{
URL = "http://192.168.0.1/cgi-bin/luci",
Method = "get",
Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
ContentType = "text/html",
Referer = "http://192.168.0.1/cgi-bin/luci/admin/system",
Cookie = cookie1,
};
HttpHelper httpHelper3 = new HttpHelper();
HttpResult result3 = httpHelper3.GetHtml(item3);
// 发送重启指令
HttpItem item4 = new HttpItem()
{
URL = "http://192.168.0.1/cgi-bin/luci/admin/system/reboot",
Method = "post",
ContentType = "application/x-www-form-urlencoded",
Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
Referer = "http://192.168.0.1/cgi-bin/luci/admin/system",
Cookie = result3.Cookie,
Postdata = "sessionid=" + cookie1 + "&cbi.submit=1&cbi.apply=1&cbi._=1610433931773&action=reboot&dummy=50724",
};
HttpHelper httpHelper4 = new HttpHelper();
HttpResult result4 = httpHelper4.GetHtml(item4);
示例2:D-Link路由器重启
D-Link路由器的登录页是http://192.168.0.1,假设用户名和密码都是admin。那么重启流程如下:
- 访问http://192.168.0.1,获取正确的登录状态和Session信息。
- 提交登录表单数据,进入路由器后台管理页面。
- 访问http://192.168.0.1/command/apply.cgi?command=reboot,发送重启指令,直接触发路由器重启。
代码实现如下:
// 获取登录状态和Session信息
HttpItem item1 = new HttpItem()
{
URL = "http://192.168.0.1",
Method = "get",
Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
ContentType = "text/html",
};
HttpHelper httpHelper1 = new HttpHelper();
HttpResult result1 = httpHelper1.GetHtml(item1);
string html1 = result1.Html;
string url1 = result1.ResponseUri.ToString();
string cookie1 = result1.Cookie;
HttpItem item2 = new HttpItem()
{
URL = url1,
Method = "post",
Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
ContentType = "application/x-www-form-urlencoded",
Postdata = string.Format("loginUsername={0}&loginPassword={1}&submit=submit", "admin", "admin"),
Cookie = cookie1,
};
HttpHelper httpHelper2 = new HttpHelper();
HttpResult result2 = httpHelper2.GetHtml(item2);
// 发送重启指令
HttpItem item3 = new HttpItem()
{
URL = "http://192.168.0.1/command/apply.cgi?command=reboot",
Method = "get",
ContentType = "application/x-www-form-urlencoded",
Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
Cookie = cookie1,
};
HttpHelper httpHelper3 = new HttpHelper();
HttpResult result3 = httpHelper3.GetHtml(item3);
总结
通过以上两个示例,我们可以学习到使用HttpHelper框架重启路由器的基本过程。在实际使用过程中,还需要注意以下几点:
- 路由器的登录页和重启地址可能会因品牌和型号不同而有所不同,需要根据实际情况修改。
- 登录表单数据和重启指令数据也需要根据实际情况修改,否则可能无法正常登录或重启路由器。
- 在使用HttpHelper框架发送POST请求时,需要设置ContentType为“application/x-www-form-urlencoded”,并使用Postdata属性来指定表单数据。
