Http client POST request xml+soap - scala

Question

I want to make a post request in Scala to this API http://api.atinternet-solutions.com/toolbox/reporting.asmx
I first did it with a curl like this :
curl -X POST -T post.txt -H "Content-Type: application/soap+xml; charset=utf-8" http://api.atinternet-solutions.com/toolbox/reporting.asmx -v
and I got what I expected.
Now I want to call the API programatically with a simple HttpClient
val httpClient = new DefaultHttpClient()
def postRequest=new HttpPost("https://api.atinternet-solutions.com/toolbox/reporting.asmx")
postRequest.addHeader("Content-Type","application/soap+xml ; charset=utf-8")
postRequest.addHeader("SOAPAction","\"http://www.xiti.com/queryReport\"")
val file=new File("post.txt")
val fe=new FileEntity(file,"application/soap+xml;charset=utf-8")
postRequest.setEntity(fe)
val httpResponse=httpClient.execute(postRequest)
println(httpResponse.getStatusLine.toString)
val rspStr=Source.createBufferedSource(httpResponse.getEntity.getContent).mkString
println(rspStr)
but I get an HTTP/1.1 500 Internal Server Error
and printing the rspStr yields
"?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><soap:Code><soap:Value>soap:Receiver</soap:Value></soap:Code><soap:Reason><soap:Text xml:lang="en">Server was unable to process request. ---> Root element is missing.</soap:Text></soap:Reason><soap:Detail /></soap:Fault></soap:Body></soap:Envelope"
The post.txt looks like below, except I set the good information instead.
<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
<soap12:Header>
<NXHeader xmlns="http://www.xiti.com/">
<GUID>string</GUID>
<SecurityKey>string</SecurityKey>
<Site>int</Site>
</NXHeader>
</soap12:Header>
<soap12:Body>
<queryReport xmlns="http://www.xiti.com/">
<startDate>int</startDate>
<endDate>int</endDate>
<query>string</query>
<param>string</param>
<typereport>XML or CSV</typereport>
</queryReport>
</soap12:Body>
</soap12:Envelope>
The curl action which is working is done from my scala project directory. I printed post.txt in scala and got the good content.
I cannot figure out what is going wrong. Thank you for your help

Answer 1

I tried your call with the dispatch library.
This is my code
import dispatch._
import java.io.File
object ToolBox {
val endpoint = url("https://api.atinternet-solutions.com/toolbox/reporting.asmx").POST
.addHeader("Content-Type","application/soap+xml ; charset=utf-8")
.addHeader("SOAPAction",""" "http://www.xiti.com/queryReport" """)
def report = Http( endpoint <<< new File("post.txt") > as.xml.Elem)
def tryReport = {
val res = report.either
for {
ex <- res.left
} yield "Something got wrong " + ex.getMessage
}
}
The service replies with a status 500 like you, but the faultString in the response xml is: A parameter is missing in your NXHeader or you have a namespace issue.
Is it what you would expect, since the post.txt body contains only the placeholders from the query report example, instead of real parameters?

Answer 2

I found what was going wrong.
Replace
def postRequest
by
val postRequest.
Tks again
