php - using curl to consume this web service - php

Question

I saw this post on consuming a web service using CURL: Consume WebService with php
and I was trying to follow it, but haven't had luck. I uploaded a photo of the web service I'm trying to access. How would I formulate my request given the example below, assuming the URL was:
https://site.com/Spark/SparkService.asmx?op=InsertConsumer
I attempted this, but it just returns a blank page:
$url = 'https://xxx.com/Spark/SparkService.asmx?op=InsertConsumer?NameFirst=Joe&NameLast=Schmoe&PostalCode=55555&EmailAddress=joe#schmoe.com&SurveyQuestionId=76&SurveyQuestionResponseId=1139';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$xmlobj = simplexml_load_string($result);
print_r($xmlobj);

Really, you should probably look at the SOAP extension. If it is not available or for some reason you must use cURL, here is a basic framework:
<?php
// The URL to POST to
$url = "http://www.mysoapservice.com/";
// The value for the SOAPAction: header
$action = "My.Soap.Action";
// Get the SOAP data into a string, I am using HEREDOC syntax
// but how you do this is irrelevant, the point is just get the
// body of the request into a string
$mySOAP = <<<EOD
<?xml version="1.0" encoding="utf-8" ?>
<soap:Envelope>
<!-- SOAP goes here, irrelevant so wont bother writing it out -->
</soap:Envelope>
EOD;
// The HTTP headers for the request (based on image above)
$headers = array(
'Content-Type: text/xml; charset=utf-8',
'Content-Length: '.strlen($mySOAP),
'SOAPAction: '.$action
);
// Build the cURL session
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $mySOAP);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
// Send the request and check the response
if (($result = curl_exec($ch)) === FALSE) {
die('cURL error: '.curl_error($ch)."<br />\n");
} else {
echo "Success!<br />\n";
}
curl_close($ch);
// Handle the response from a successful request
$xmlobj = simplexml_load_string($result);
var_dump($xmlobj);
?>

Answer 2

The service requires you to do a POST, and you're doing a GET (curl's default for HTTP urls) instead. Add this:
curl_setopt($ch, CURLOPT_POST);
and add some error handling:
$result = curl_exec($ch);
if ($result === false) {
die(curl_error($ch));
}

This is the best answer because using this once you need to login then
get some data from webservices(third party site data).
$tmp_fname = tempnam("/tmp", "COOKIE"); //create temporary cookie file
$post = array(
'username=abc#gmail.com',
'password=123456'
);
$post = implode('&', $post);
//login with username and password
$curl_handle = curl_init ("http://www.example.com/login");
//create cookie session
curl_setopt ($curl_handle, CURLOPT_COOKIEJAR, $tmp_fname);
curl_setopt ($curl_handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $post);
$output = curl_exec ($curl_handle);
//Get events data after login
$curl_handle = curl_init ("http://www.example.com/events");
curl_setopt ($curl_handle, CURLOPT_COOKIEFILE, $tmp_fname);
curl_setopt ($curl_handle, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec ($curl_handle);
//Convert json format to array
$data = json_decode($output);
echo "Output : <br> <pre>";
print_r($data);
echo "</pre>";
