Use libcurl to sign into webpage?
See both C++ and page source code below. I want to use libcurl to enter a username and password into the appropriate fields on the webpage and then click the submit button. What changes to the code below do I need to make?
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <curl/curl.h>
#include <curl/types.h>
#include <curl/easy.h>
int main()
{
curl_global_init( CURL_GLOBAL_ALL );
CURL * myHandle = curl_easy_init ( );
// Set up a couple initial paramaters that we will not need to mofiy later.
curl_easy_setopt(myHandle, CURLOPT_USERAGENT, "Mozilla/4.0");
curl_easy_setopt(myHandle, CURLOPT_AUTOREFERER, 1 );
curl_easy_setopt(myHandle, CURLOPT_FOLLOWLOCATION, 1 );
curl_easy_setopt(myHandle, CURLOPT_COOKIEFILE, "");
// Visit the login page once to obtain a PHPSESSID cookie
curl_easy_setopt(myHandle, CURLOPT_URL, "my website");
curl_easy_perform( myHandle );
// Now, can actually login. First we forge the HTTP referer field, or HTS will deny the login
curl_easy_setopt(myHandle, CURLOPT_REFERER, "my website");
// Next we tell LibCurl what HTTP POST data to submit
char *data="Name/Badge=1234&Password=1234";
curl_easy_setopt(myHandle, CURLOPT_POSTFIELDS, data);
//curl_easy_setopt(myHandle, CURLOPT_POSTFIELDS, 'ctl00$LogInButton[]=Sign in');
curl_easy_perform( myHandle );
curl_easy_cleanup( myHandle );
return 0;
}
HTML
Code:
<div id="loginForm">
<div id="loginInput">
<label for="ctl00_LoginTextBox" id="ctl00_LoginLabel">Name/Badge</label>
<input name="ctl00$LoginTextBox" type="text" id="ctl00_LoginTextBox" class="PopupInput" />
</div>
<div id="passwordInput">
<label for="ctl00_PasswordTextbox" id="ctl00_PasswordLabel">Password</label>
<input name="ctl00$PasswordTextbox" type="password" id="ctl00_PasswordTextbox" class="PopupInput" />
</div>
<div id="equipmentbox">
</div>
</div>
<div id="ctl00_LoginButtons">
<input type="submit" name="ctl00$LogInButton" value="Sign in" id="ctl00_LogInButton" class="btn" />
<input type="submit" name="ctl00$SwitchLoginScreenModeBT" value="Change Password" id="ctl00_SwitchLoginScreenModeBT" class="btn" />
