VC submits webpage form-automatic comment (1)

Some time ago, after carefully reading an HTTP protocol, I wrote such an automated comments test program. Below are my study notes for this study experiment:

I. preparations:

1. Local Environment: Windows XP SP3, 10 m ADSL Optical Fiber

2. Development Tool: WildPackets OmniPeek V5.1.4

Visual C ++ 6.0

Netpas eight horses free VPN proxy (avoid IP address seizure)

FlexEdit V2.3.1871 (temporarily retain text)

3. webpage program: LBS Version 2.0.313

Ii. analyze data packets:

1. Open the LBS V2.0.313 blog program and you can see the following comments (first look for the ones without verification code !)

 

2. Set the OmniPeek filter type:

 

3. Click "Start packet capture" and manually comment once to capture the data packet. The following red lines are useful:

4. Actual raw data packet content:

5. After being parsed by OmniPeek, view the following content:

6. Check the first three fields and the last three fields. We can analyze them and the comment is actually

POST/blog/comment/asp? Act = save & logid = 3567 HTTP/1.1

E_ubb = true & e_autourl = true & e_smilies = true & comm_username = % E5 % A4 % A9 % E4 % BD %

BF & comm_password = & message = www. ****** .net.cn

After the analysis is complete, we began to prepare the POST data packet with the SOCKET!
