First, start from scratch to make a web QQ robot, the first step to get Smart QQ QR code

Beginner Tutorials:

Preface: Recently looked at a long time ago to do the QQ robot failed, and recently also in the job, the time is very comfortable. Decided to start a new web QQ Robot PC protocol parsing out a little time later to do.

Preparatory work:

Compilation tool: vs2017

Programming languages: C # or. Net

Start building an SDK new file-project-Select Class Library-(WEBQQSDK)-Add a class SMARTQQ

The first step, login to the smart QQ, to this HTTP protocol, do robot interaction Bar, TX to this version of a lot of features removed, basic group chat, private chat and other information is still in. (Use Google Chrome to access http://web2.qq.com/press F12 to enter the developer window to enter Network-all)

Start the connection to the QR code name is/ptqrshow. The request connection of the QR code

https://ssl.ptlogin2.qq.com/ptqrshow?appid=501004106&e=2&l=M&s=3&d=72&v=4&t= 0.05929581762262637&daid=164&pt_3rd_aid=0

The yellow one is random. Later you can get a random. I've done an HTTP communication class before, and these will be open source to the code cloud above.

private static Random Rand = new Random ();
static int ptqrtoken = 0;//Check the QR code status needs to be verified
<summary>
The first step is to get the QR code
</summary>
<returns></returns>
public static Image Login_getqrcode ()
{

HttpWebRequest req = (HttpWebRequest) webrequest.create ("https://ssl.ptlogin2.qq.com/ptqrshow?appid=501004106& E=2&l=m&s=3&d=72&v=4&t=#{t}&daid=164&pt_3rd_aid=0 ". Replace ("#{t}", Rand. Nextdouble (). ToString ()));
Req. Cookiecontainer = http.cookies;//Set Cookies
HttpWebResponse res = (HttpWebResponse) req. GetResponse ();//request to Response can compare the developer interface data
Ptqrtoken = HTTP. Hash33 (HTTP. Getallcookies (Res. Cookies);//save, check the QR code status needs to be verified.
Return Image.fromstream (Res. GetResponseStream ());

}

This has been acquired to the QR code. Create a new Login Form window, pull a PictureBox component, and a button.

Window Login Code

private void Button1_Click (object sender, EventArgs e)
{
pictureBox1.Image = Smartqq.login_getqrcode ();
}

Run

Run the result, this is the login QR code. The first step is done here.

HTTP class

<summary>
HTTP network Communication Class
</summary>
public static Class HTTP
{

public static Cookiecontainer cookies = new Cookiecontainer ();
<summary>
Hash Conversion
</summary>
<param name= "S" ></param>
<returns></returns>
public static int Hash33 (string s)
{
var e = 0;
foreach (Var t in s)
E + = (e << 5) + t;
return int. MaxValue & E;
}
<summary>
Get all Cookies under cookiecollection
</summary>
<param name= "CC" ></param>
<returns></returns>
public static string Getallcookies (Cookiecollection cc)
{
list<cookie> lstcookies = new list<cookie> ();
String lstcookies = "";
ArrayList table = (ArrayList) cc. GetType (). InvokeMember ("M_list",
System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.GetField |
System.Reflection.BindingFlags.Instance, NULL, CC, new object[] {});

if (table! = null)
{
for (int i = 0; i < table. Count; i++)
{
string[] Tacookie = Table[i]. ToString (). Split (' = ');
Lstcookies = tacookie[1]. ToString (). Trim ();
}
}

return lstcookies;
}
}
