Hello, I was wondering if one of you could give me a snippet of reading a websites raw text for a boolean or function. Like I have a page on my site with true or false that way I can make my turtle or computer work over the internet. I know its possible but have lost interest in computercraft and forgot alot and never knew anything about https

this code doesn't work its for better understanding of my question

website = http://www.example.com/cc
if website == "true" then
print("It works!")

You'll want to use http.get

local webHandle = http.get( "http://www.example.com/cc" )
if webHandle then
  print( webHandle.readAll() )
else
  print( "Couldn't connect to website :(/>" )
end

Thankyou. this is a good way for an auto updater!

[TyDoesMC]

It always say update found my code is very basic.


version = http.get("http://pastebin.com/raw.php?i=9nXEnf7x")
currentVersion = "1.0.0"

if currentVersion ~= version then
print("Update found!")
else
print("No update")

http.get() returns a web handle. You can read data from this handle, but the handle does not directly represent the data itself. Take another look at what Yami's doing in his example, at this article, and at this section.

Ok I updated it.

still doesn't work.
I added

version_read = version.readAll()
then I use version_read in place but still no avail.

version = http.get("http://pastebin.com/raw.php?i=9nXEnf7x")
currentVersion = "1.0.0"
version_read = version.readAll()

if currentVersion ~= version_read then
print("Update found!")
else
print("No update")

[KingofGamesYami]

Try this:

local h, version = http.get( "http://pastebin.com/raw.php?i=9nXEnf7x" )
if h then
  version = h.readAll()
  print( version )
  if version ~= "1.0.0" then
    print( "Update Found!" )
  else
    print( "No Update Found!" )
  end
else
  print( "Couldn't connect to pastebin!" )
end

What does this print?

[TyDoesMC]

Ok it works ty

Why won't this work?
It updates no matter what.

A quick shot-in-the-dark guess, but what happens if you switch to h.readLine() instead of h.readAll()? I suspect you're pulling in a linebreak you don't want.

It'd also be a good idea to call h.close() after your read.

You actually have to close http handles?

They time out sooner or later if you don't, but there's no point in having them consume resources for longer than they have to.
