C + + Implementation Request Account---Send post submission form packets

First of all to determine the submission form information, I use the grab Bag tool grabbed the post package, and then write the program to simulate the sending process, the implementation of the login process.

Precautions:

1. Be sure to follow the packet to send the message, even the space, the number of lines to be the same;

2. No verification code for the Web page of the demo login;

Code:

Operation Result:

1. Form information submitted to the website

2. Return information for Web pages

3. Return information upon successful application

4. Run this program to return information here
