Errors on a first step

[robopet3]

Hi all.
I practically didn’t work with API before, so I took an example from here
http://wiki.dwscoalition.org/wiki/index.php/XML-RPC_Protocol_Method:_postevent
as it is, and and got an error


faultCodeClientfaultStringApplication failed during request deserialization:
XML or text declaration not at start of entity at line 1, column 1, byte 1 at /home/dw/current/extlib/lib/perl5/x86_64-linux-gnu-thread-multi/XML/Parser.pm line 187.



Could anyone please tell me which client is needed to work with and in what field ?
Thank you all in advance

UPD
Fixed, by replace ESC 0D 0A by
$ReturnTextPostTestMessage01.Replace("`r`n","")

For the example request, don't include the sample HTTP headers given in the syntaxhighlight block. The error indicates that the line that specifies the XML version needs to be the first line. The data you send should start there.

[robopet3]

I don't inculde first.
code:
----
function PostTestMessage01{

param([string]$F_UserID, [string]$F_UserPass)


$ReturnTextPostTestMessage01 = ''

$Now = Get-Date

$ReturnTextPostTestMessage01 = '


LJ.XMLRPC.postevent




username
' + $F_UserID + '
'

$ReturnTextPostTestMessage01 = $ReturnTextPostTestMessage01 +
# auth_method
'auth_method
cookie
'


$ReturnTextPostTestMessage01 = $ReturnTextPostTestMessage01 +


'event
This is a test post 001 Alpha


subject
Test subject 002 B

lineendings

pc

year
' + ($Now.Year.ToString()) + '


mon
' + ($Now.Month.ToString()) + '

day

'+ $Now.Day.ToString() +'

hour
' +$Now.Hour.ToString() + '


min
' + $Now.Minute.ToString() + '





'


return $ReturnTextPostTestMessage01
}

$Body4Post = PostTestMessage01 $DreamUsername $DreamPass
$DreamAnswer002 = Invoke-WebRequest -Uri $DreamUrlxmlrpc -Method Post -Body $Body4Post -ContentType "text/xml"

Is there a newline character in front of the xml version line? That seems like the most likely culprit.

[robopet3]

$Body4Post.Substring(0,26) | Format-Hex
00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00000000 0D 0A 3C 3F 78 6D 6C 20 76 65 72 73 69 6F 6E 3D ....<

yes, there are
0D 0A

faultCodeClientfaultStringApplication failed during request deserialization:
not well-formed (invalid token) at line 1, column 1, byte 2 at /home/dw/current/extlib/lib/perl5/x86_64-linux-gnu-thread-multi/XML/Parser.pm line 187.


so I fixed it inccorrect way
$ReturnTextPostTestMessage01 = $ReturnTextPostTestMessage01.Replace("`r`n","`0") #incorrect - 3F 3E !---00!--- 3C 6D

with differenet error (let it be here as example)
faultCodeClientfaultStringApplication failed during request deserialization:
not well-formed (invalid token) at line 1, column 1, byte 2 at /home/dw/current/extlib/lib/perl5/x86_64-linux-gnu-thread-multi/XML/Parser.pm line 187.


and after check
$ReturnTextPostTestMessage01 = $ReturnTextPostTestMessage01.Replace("`r`n","")


it's look better - just "Invalid password"

faultCode101faultStringInvalid password


Thanks a lot

After some another stupid fixes such as "(space) /int>" - it's works.c

Thanks again

Glad I could help!
