18F87J50 as a webserver

**Christopher4187** · - 11th February 2014, 15:54

Agmen, can you help me a little more. I've been trying get the web server to work but I'm having no success. I'm confused about a few things so I stripped all of the features out of the code and went with something very simple.

I'm trying to use this code:

Code:

 IF MESSAGE1[0]="G" AND MESSAGE1[1]="E" AND MESSAGE1[2]="T" THEN 
             LCDOUT $FE, 192, "SERVER HIT!"
             HIGH LED1G
             HIGH LED2G
             HIGH LED3G
             HSEROUT [13,13]
               HSEROUT["<HTTP/1.0 200 OK Content-Length: 800>",13]
      HSEROUT ["Content-Type: text/html",13]
      hserout [13]
          hserout ["<html>",13]
          hserout ["<head>Test page</head>",13]
          HSEROUT ["<body>This is a test page</body>",13]
           hserout ["</html>",13]
            HSEROUT [13,13]
            PAUSE 500

Why doesn't this work? When I pull it up on a webpage, it doesn't work correctly. When I use "0,0,0" at the end, the webpage acts like it wants to download a file. Can you point me in the right direction?

hi,
My best understanding (and not real clear), the HTTP stuff uses the "Content-Length: ???" to give the html stuff the right amount of bytes then close the connection and render the page.
Try to figure what would be the correct 'Content-Length: ' and/or send at least that many serial bytes in 'Content-Length:???'.
and please share technical info of successes and failures.
I have been trying to keep up with web stuff, I think things get more straight forward as they evolve...... like HTML5
Seems like there should have been a command to "render page now" in html, but I could not find one for that in much google search.

Will do. One additional question. Why don't you have this line of code:

Code:

"HTTP/1.0 200 OK",13,"Content-Length: 800 ",13,13

written like this:

Code:

"<HTTP/1.0 200 OK",13,"Content-Length: 800>",13,13

there is a blank line required separating the HTTP header and html code.
I don't remember exactly what web, but search for HTTP explained has more info.....tons of info....too much info !!
good luck
