Hello experts,

I have tried to read data from a web page with the PicoW.
Unfortunately it did not work. Then I tried
to use the GET request block of my FireFox.
But it is longer than a string allows.

WEB TCP CLIENT REQUEST query$, inbuf [, timeout]
Longstring does not work as parameter for query$.

Also parts of the block did not work.

I always get the Bad Request error message.

Here is the program and the result:

' HTTP Client

Dim buff%(8000)

If MM.Info(ip address) = "0.0.0.0" Then
Print "Kein WLAN ... Neustart ... "
CPU restart
EndIf

WEB ntp +2, "fritz.box" ' Germany = +2 hours summer time

Print "Connected to W-Lant ... "

Dim Query$ = "GET /index.html HTTP/1.1"+Chr$(10)+Chr$(13)
Query$ = Query$ +"Host: www.thebackshed.com"+Chr$(10)+Chr$(13)
Query$ = Query$ +"User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64;"
Query$ = Query$ +" rv:109.0) Gecko/20100101 Firefox/111.0"+Chr$(10)+Chr$(13)
Query$ = Query$ +"Accept: text/html"+Chr$(10)+Chr$(13)

Query$ = Query$ +"Accept-Encoding: gzip, deflate"+Chr$(10)+Chr$(13)
Query$ = Query$ +"Connection: keep-alive"+Chr$(10)+Chr$(13)
Query$ = Query$ +Chr$(10)+Chr$(13)
Print :Print "Query$:"
Print Query$
Print "End of Query$":Print
