x

Well done! In order to explore WEBQQ HTTP request flow and data interaction, I paid a lot of effort.

Write down this article!!! This is my lost youth.

I will pack the source code after the series is finished

------My journey is the star of the Sea

One go to webqq page

Two Check if a verification code is requiredFirst get once for this page, save the cookie

After the user has entered the QQ number, an HTTP request will be triggered to detect whether the account requires a verification code.

Request Address: "https://ssl.ptlogin2.qq.com/check?uin=" + Qqnum + "&appid=501004106&js_ver=10095&js_type=0 &login_sig=a9nq-9*pnzkfxzp7jce7vorx5z9x6khffy44fkhikad-n8fshtak1r1gzrjgsxza&u1=http%3a%2f%2fw.qq.com% 2fproxy.html&r=0.6158497643191367 ";

Three No verification code is required to return the result

Analysis:

1. Here is the use of the Jsonp method, the security of QQ number is detected

2. The operation of this figure does not require verification code check

3. The first 4 parameters of the method are used:

• 1 means a verification code is required, and 0 means the QQ number is safe.
• The second parameter indicates the verification code, QQ security indicates that you do not have to enter the verification code, TX will help you to generate the background verification code ...
• QQ number 16 in the system
• Verifysession, after the article is used, save it first

Four The return result of the verification code is required

Analysis:

1. Here is the use of the Jsonp method, the security of QQ number is detected

2. The operation of this figure requires verification code check (multiple login, IP anomaly, etc.)

3. The parameters returned are only the first one, 1 means that a verification code is required, and 0 means that the QQ number is safe.

Five When you need a verification code, download the Verification code

1. Requested address: "https://ssl.captcha.qq.com/getimage?aid=501004106&r=0.8478438374586403&uin=" + qqnum;

2. Request to bring Referer: "https://ui.ptlogin2.qq.com/cgi-bin/login?daid=164&target=self&style=16&mibao_css= m_webqq&appid=501004106&enable_qlogin=0&no_verifyimg=1&s_url=http%3a%2f%2fw.qq.com% 2fproxy.html&f_url=loginerroralert&strong_login=1&login_state=10&t=20131024001 ";

3. After obtaining the picture, you need to save the cookie of the request

4. Find the value of "verifysession" from the cookie and save it
