Samples

Sample request from a Linux client using perl

To install use:

root@myLVS-LinuxClient:~# apt-get install libsoap-lite-perl

Sample script (test.pl)

#!/usr/bin/perl -w
use SOAP::Lite; # + qw/ trace /;
my $soap = SOAP::Lite
  -> uri('urn:lvs')
  -> proxy('http://ws.mylvs.foo/cgi-bin/lvs.cgi');
my $result = $soap->WHATISMYIP ();
unless ($result->fault) {
 print $result->result();
} else {
  print join ', ',
    $result->faultcode,
    $result->faultstring;
}

Sample script (test.pl)

root@myLVS-LinuxClient:/usr/local/dev/mylvs# perl test.pl
200 192.168.2.222






Sample request from a Windows client using perl

To install the ActiveState Perl Module use:

C:\Users\Administrator\Documents\lvs> ppm install Soap-Lite

Sample script (test.pl):

#!/usr/bin/perl -w
use SOAP::Lite; # + qw/ trace /;
my $soap = SOAP::Lite
 -> uri('urn:lvs')
 -> proxy('http://ws.mylvs.foo/cgi-bin/lvs.cgi');
my $result = $soap->WHATISMYIP ();
unless ($result->fault) {
 print $result->result();
} else {
  print join ', ',
  $result->faultcode,
  $result->faultstring;
}

Sample script (test.pl):

C:\Users\Administrator\Documents\lvs>perl test.pl
200 192.168.2.221






Sample request from a Windows client using cscript with MSXML

Set xmlReq = CreateObject("MSXML2.DOMDocument.6.0")
request="<SOAP-ENV:Envelope xmlns:xsi='http://www.w3.org/1999/XMLSchema-instance' " 
request = request & "xmlns:SOAP-ENC='http://schemas.xmlsoap.org/soap/encoding/' "
request = request & "xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/' "
request = request & "xmlns:xsd='http://www.w3.org/1999/XMLSchema' "
request = request & "SOAP-ENV:encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'>"
request = request & "<SOAP-ENV:Body><mylvs:WHATISMYIP xmlns:mylvs='urn:lvs'/>"
'request = request & "<c-gensym3 xsi:type='xsd:string'>192.168.xx.yy</c-gensym3>" 'alternative param
request = request & "</SOAP-ENV:Body></SOAP-ENV:Envelope>"
xmlReq.loadXML  request 'load our request
Set xmlRes = CreateObject("MSXML2.XMLHTTP.6.0")  
xmlRes.open "POST", "http://ws.mylvs.foo/cgi-bin/lvs.cgi"
xmlRes.send (xmlReq)
while xmlRes.readyState <> 4
wend
Set objDispatch =  xmlRes.responseXML
set xmlDoc = CreateObject("MSXML2.DOMDocument")
xmlDoc.Load objDispatch
WScript.Echo xmlDoc.selectSingleNode("//WHATISMYIPResponse").text

Sample script (test.vbs):

C:\Users\Administrator\Documents\lvs>cscript test.vbs //Nologo
200 192.168.2.221




Sample request from a Windows client using cscript with SoapLite

Soaplite is a smart way to handle our request. It still runs as 32bit application on Server2012
but it requires the 32bit part of cscript.

Soaplite must be registered with the 32bit part of regsvr:

C:\Users\Administrator\Documents\lvs>c:\Windows\SysWOW64\regsvr32.exe Lite.dll

Sample script (test-lite.vbs):

strSoapProxy="http://ws.mylvs.foo/cgi-bin/lvs.cgi"
strSoapURI = "urn:lvs"
set wso = CreateObject("SOAP.Lite").new("proxy", strSoapProxy, "uri",strSoapURI )
'wscript.echo  wso.WHATISMYIP(strBLA).result 'Sample for an alternative parameter
wscript.echo  wso.WHATISMYIP().result

Sample script (test-lite.vbs):

C:\Users\Administrator\Documents\lvs>c:\Windows\SysWOW64\cscript.exe test-lite.vbs //nologo
200 192.168.2.221






Requirements and functions

The above samples are required to be setup additional mySQL data, see more details here:

Function Optional Paramter Description Return
REQUESTWEIGHTDOWN String (a ip address like 192.168.1.1) Request to set the host offline String (Code(d{3}) Description
REQUESTWEIGHTUP String (a ip address like 192.168.1.1) Request to set the host online String (Code(d{3}) Description
REQUESTWEIGHTSTATUS String (a ip address like 192.168.1.1) Request the current status String (Code(d{3}) Description
REQUESTGROUPINFORMATION String (a ip address like 192.168.1.1) Request the current group configuration String (Code(d{3}) Description
WHATISMYIP - - -


Return Codes

  • The LVS-WFE Webservice retruns the following codes:

    • 2nn = Success
    • 3nn = Logical Errors
