C#教程之检查二维码的失效状态

在开发者界面用可以看到很多ptqrlogin开头的 name

我要做的就是  模拟浏览器的操作，把它转换成我们自己的客户端。所以只要是浏览器里有的我们都要模拟。接下来判断二维码失效，两秒一次吧，弄一个Timer

 

 

smart 类

#region 第二讲检查二维码状态
private static System.Timers.Timer StatuTimer = new System.Timers.Timer();
public static void Login()
{
StatuTimer.AutoReset = true;
StatuTimer.Elapsed +=StatuTimer_Elapsed;
StatuTimer.Interval = 2000;
StatuTimer.Start();
}

public static string Login_err = "其他";
/// <summary>
/// 检查二维码状态
/// </summary>
public static void Login_GetStatu()
{
string dat;
dat = HTTP.Get(string.Format("https://ssl.ptlogin2.qq.com/ptqrlogin?ptqrtoken={0}&webqq_type=10&remember_uin=1&login2qq=1&aid=501004106&u1=https%3A%2F%2Fw.qq.com%2Fproxy.html%3Flogin2qq%3D1%26webqq_type%3D10&ptredirect=0&ptlang=2052&daid=164&from_ui=1&pttype=1&dumy=&fp=loginerroralert&0-0-157510&mibao_css=m_webqq&t=undefined&g=1&js_type=0&js_ver=10184&login_sig=&pt_randsalt=3", ptqrtoken));
string[] temp = dat.Split('\'');
switch (temp[1])
{
case ("65"): //二维码失效
Login_err = "二维码失效";
break;
case ("66"): //等待扫描
Login_err = "等待扫描";
break;
case ("67"): //等待确认
Login_err = "等待确认";
break;
case ("0"): //已经确认

StatuTimer.Stop();
break;

default: break;
