What variable(s) would you like to send/receive?

Cheers,

The simplest for the scripts I use is usually
script.php?var=123&statustring=hello

I've been mucking around with php for a decade or two.

Cheers,

Chris.

Well, I've got this far...

Function getTest(servaddr$,servport,tcpreq$) As string
Local return%(64) ' 512 chars
WEB OPEN TCP CLIENT servaddr$, servport%
WEB TCP CLIENT REQUEST tcpreq$+" HTTP/1.1"+Chr$(10)+Chr$(13), return%()
getTest$="done"
LongString Print return%()
WEB CLOSE TCP CLIENT

getTest("192.168.0.32",8081,"GET /status/ldata.php")

spits to the console:

HTTP/1.1 400 Bad Request
Date: Thu, 16 Nov 2023 01:53:46 GMT
Server: Apache/2.4.25 (Debian)
Content-Length: 301
Connection: close
Content-Type: text/html; charset=iso-8859-1
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>400 Bad Request</title>
</head><body>
<h1>Bad Request</h1>
<p>Your browser sent a request that this server could not understand.<br />
</p>
<hr>
.......... etc

This is a local server, and a known good request (eg: http://192.168.0.32:8081/status/ldata.php works)

Still, it's a start.

Cheers,

Chris

It may not -probably does not - like that you send LF then CR.

(Being chr$(10) then chr$(13).)

A previous webserver didn't like them in the wrong order.

Spot On John!

Function getTest(servaddr$,servport,tcpreq$) As string
Local return%(64) ' 512 chars
WEB OPEN TCP CLIENT servaddr$, servport
getTest$="GET "+tcpreq$+" HTTP/1.1"+Chr$(13)+Chr$(10)+"Host: "+servaddr$+":"+Str$(servport)+Chr$(13)+Chr$(10)+"Connection: keep-alive"+Chr$(13)+Chr$(10)+Chr$(13)+Chr$(10)
WEB TCP CLIENT REQUEST getTest$, return%()
LongString Print return%() ' for now
WEB CLOSE TCP CLIENT
End Function

Now works like a charm.

Calling getTest("192.168.0.32",8081,"/status/ldata.php") spits back exactly what I expected.

Cheers, Chief.

Not a problem, sir.

you should be able to use the usual eg "scriptname.php?var1=10&var2=fred" to pass variables, although I'm unsure about the webmite handling spaces in strings.

Cheers,

Chris.
