help with POST in "freescale_http.c"

NT — Sun, 06 Apr 2008 02:06:31 GMT

According to the description of “freescale_http.c”, the web server supports ‘GET’,’POST’,’EMG’.

But void freescale_process_header(int session, char *buffer, int bytesread) only supports GET and EMG. I am not able to add code that supports POST. Can anyone help me to add the code that supports POST too.

Thanks

Change RECV_BUFFER_SIZE and MAX_HEADER_READS as required. You can find the size by looking at the contents that webpage sends during post method. You can do this using wireshark.

The function to process “POST”method is as follows.

if( freescale_http_sessions[session].headertype == TYPE_POST )

{

collect_sensor_data( );

if( filename[0] )

pre_process_post_filename( filename );

if(passwd_flag ==1)

{

emg_web_open( session, filename );

}

else

emg_web_open(session,"pwd_incorrect.htm");

freescale_http_sessions[session].state = EMG_HTTP_STATE_SEND_FILE;

} // end of if TYPE_POST
