HTTP GET - Trouble parsing text/html

[djgutheinz]

I am having problems with a simple HTTP GET command parsing of the return. I usually use HubAction to send the command, but need an explicit response before continuing to the next step in the method. Obviously I am missing something, but I am at a loss.

Below are two elements:

• method newSendCmd which calls the post and response (I added some elements to document the return data in log.
• log of the response (shows problem in two errors on XmlSlurper and XmlParser).

Method newSendCmd:

private newSendCmd(command){
	def host = "http://192.168.0.127:55001"
	httpGet("${host}${command}") { response ->
		log.info "status: ${response.getStatus()}"
		log.info "contentType: ${response.getContentType()}"
		log.info "data: ${response.getData()}"
		log.info "context: ${response.getContext()}"
		log.info "entity: ${response.getEntity()}"
		log.info "locale: ${response.getLocale()}"
		log.info "tatusLine: ${response.getStatusLine()}"
		def data = response.data
		log.debug data
		def cmdResp = "DID NOT WORK"
		try { cmdResp = new XmlParser().parseText(data) }
		catch (error) { log.error "XmlParser: ${error}" }
		try { cmdResp = new XmlSlurper().parseText(data) }
		catch (error) { log.error "XmlSlurper: ${error}" }
		log.debug cmdResp
	}
}

No signature of method: groovy.util.XmlSlurper.parseText() is applicable for argument types: (groovy.util.slurpersupport.NodeChild

The error looks like you're trying to parse something that's already xml.

In the following post the XML was automatically parsed - did you try using response.data as an XML object directly?

Retrieve and parse xml data

Alright, so the response from the server is getting parsed into a GPathResult automatically. You can read up about it here: The Apache Groovy programming language - Processing XML result.data is your "apps" node of the xml and you can get its first child like this: response.data.app[0] and get the data in the node like this: response.data.app[0].text() or any attribute on the node with the @ symbol like this: response.data.app[0].@version Here is your chunk of code modified so it will p…

Thanks. I had tried that in the base command. problem was the ContentType not being there. By doing that, I am able to get the data I need. Now it is all better!
