Sending XML String through HTTP post
 
|
Hi guys,
I've been working on accomplishing the relatively simple task of sending a XML string through a POST request but am running into a lot of roadblocks .. I tried def request = """<?xml version="1.0" encoding="UTF-8"?> <requestMobilePaymentProcessEntrypoints xmlns="http://apps.shaun.com/shaunpay" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://apps.shaun.com/shaunpay/shaunpay.xsd"> <customerKey>a1w2e3r4g5</customerKey> <schCode>USK</schCode> <maxNumber>1</maxNumber> <items currency="USD" /> </requestMobilePaymentProcessEntrypoints> """ def url = new URL("http://apps.shaun.com/shaunpay/actions/default?method=lookup") def conn = url.openConnection() conn.setRequestProperty("Content-Type", "text/xml") conn.requestMethod='POST' //conn.addRequestProperty("request",request) conn.doOutput = true conn.doInput = true; Writer wr = new OutputStreamWriter(conn.outputStream) wr.write(request) wr.flush() wr.close() conn.connect() println conn.responseCode println conn.responseMessage and am getting a 400 status code error, which I take it to mean malformed syntax. I need to send the XML string as a value pair - name = "request", and xml string. Tried doing that with conn.addRequestProperty but got errors. Any help would be greatly appreciated. Also, I tried using HttpBuilder but it complained about a missing HttpRequestBase class. Added the Httpclient jar file into my lib folder to no avail. Am frustrated as hell.. Shaun |

Looks to me like your doing it the hard way. Check out HTTP Builder and
the rest plugin which uses HTTPBuilder On Thu, Oct 22, 2009 at 5:51 PM, ShaunLim <[hidden email]> wrote:

You probably need the Http-Core JAR for HTTPBuilder as well. Download
this package: http://repository.codehaus.org/org/codehaus/groovy/modules/http-builder/http-builder/0.5.0-RC2/http-builder-0.5.0-RC2-all.zip and it will have all of the necessary dependencies. As for your URL example above, I don't think you want to "connect" after writing to the request stream. Can you verify what (if any) data is getting to the server? Is it being sent as a POST request? -Tom 2009/10/22 ShaunLim <[hidden email]>: > > Hi guys, > > I've been working on accomplishing the relatively simple task of sending a > XML string through a POST request but am running into a lot of roadblocks .. > > I tried > > def request = """<?xml version="1.0" encoding="UTF-8"?> > <requestMobilePaymentProcessEntrypoints > xmlns="http://apps.shaun.com/shaunpay" > xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > xsi:schemaLocation="http://apps.shaun.com/shaunpay/shaunpay.xsd"> > <customerKey>a1w2e3r4g5</customerKey> > <schCode>USK</schCode> > <maxNumber>1</maxNumber> > <items currency="USD" /> > </requestMobilePaymentProcessEntrypoints> > """ > > def url = new > URL("http://apps.shaun.com/shaunpay/actions/default?method=lookup") > def conn = url.openConnection() > > > conn.setRequestProperty("Content-Type", "text/xml") > conn.requestMethod='POST' > //conn.addRequestProperty("request",request) > conn.doOutput = true > conn.doInput = true; > > Writer wr = new OutputStreamWriter(conn.outputStream) > wr.write(request) > wr.flush() > wr.close() > > conn.connect() > println conn.responseCode > println conn.responseMessage > > and am getting a 400 status code error, which I take it to mean malformed > syntax. > > I need to send the XML string as a value pair - name = "request", and xml > string.

Hey Tom,
I got it to work .. somewhat. Here's how: def http = new HTTPBuilder('http://apps.shaun.com/shaunpay/actions/default?method=lookup') def postBody = [request:request] //parameter name: "request", value is a variable named "request" //def postHeaders = [Accept: 'application/xml'] //requestContentType: URLENC http.post( headers: [Accept: 'application/xml'], body: postBody ) { resp,reader -> println "-----Response-----" println "${resp.statusLine}" //def xml = new XmlSlurper().parse(reader) println reader.getClass().toString() println "\n------------------" } - The problem is that I'm expecting a XML return but am getting a groovy.util.slurpersupport.NodeChild return that I can't parse with XMLSlurper. Is there a way to explicitly get a XML return? Thanks! Shaun

The NodeChild is the parsed output from XmlSlurper :) HttpBuilder
does that part for you! Your response closure parameter named "reader" is actually a GPathResult, so you can do "println reader.name()" and "reader.children().each { println it.name() }" etc etc. 2009/10/23 ShaunLim <[hidden email]>: > > Hey Tom, > > I got it to work .. somewhat.

Hi Shaun,
Just to follow up in case you're still working on this -- I've updated the site documentation here: http://groovy.codehaus.org/modules/http-builder/doc/xml.html With a working example that should help you understand it better.
