I'm trying to parse the xml response from a soap service. However, I can't get simplexml_load_string to work! Here is my code:
//make soap call
objClient = new SoapClient('my-wsdl',
array('trace' => true,'exceptions' => 0, 'encoding' => 'UTF-8'));
$soapvar = new SoapVar('my-xml', XSD_ANYXML);
$objResponse = $objClient->__soapCall($operation, array($soapvar));
//process result
$str_xml = $objClient->__getLastResponse();
$rs_xml = simplexml_load_string($str_xml);
...$rs_xml always has just one element with name Envelope.
However, if I use *"print var_export($objClient->__getLastResponse(),true);"* to dump the result to my browser, then cut and paste it into my code as a string variable, it work fine! This is what I mean:
$str_xml = 'my cut and pasted xml';
$rs_xml = simplexml_load_string($str_xml);
So it seems the problem is somehow related to something $objClient->__getLastResponse() is doing to the string it creates... but I'm at a loss as to what the problem is or how to fix it.
Do the following:
$str_xml = $objClient->__getLastResponse();
$str_xml = strstr($str_xml, '<');
$rs_xml = simplexml_load_string($str_xml);
As it's a quick and easy hack to strip off stuff before the first opening element.

I'm using Guzzle with Laravel to get an object from external API with a HTTP. The API return XML Object similar to this (https://www.w3schools.com/php/note.xml)
I need to check one value of the response body. Here is my code:
$client = new \GuzzleHttp\Client();
$res = $client->request('GET', 'https://www.w3schools.com/php/note.xml');
$stringBody = (string) $res->getBody()->getContents();
echo $stringBody;
which is working fine, I mean it display the body as below picture
but I couldn't get one value?
I tried different methods but non of them is working!
for example, this way:
$result = starts_with($stringBody, 'Tove');
or
splitName = explode(' ', $res->getBody());
$first_name = $splitName[0];
echo $first_name;
non is working? I think it consider the body text empty ?
I tried using json_decode but it doesn't work or not supported anymore.
Any idea?
Thanks
What you get from response is xml content. Due to browser compatibility with XML you see only text. You just need SimpleXML class of php for get content as per XML node. Here is sample code
$client = new \GuzzleHttp\Client();
$res = $client->request('GET', 'https://www.w3schools.com/php/note.xml');
$stringBody = (string) $res->getBody()->getContents();
$xml = simplexml_load_string($stringBody);
echo $xml->to;
Hope this help you.
I have a SPA (react) that is uses PHP calls to connect to a MongoDB.
Works great.
However, due to 'rules' I need to serve the javascript files from a different server -- a server that supports neither MongoDB nor MongoDB php client. Let's call this server, SERVER_A.
Let's call the server hosting the MongoDB PHP client and the MongoDB, SERVER_B. ('B' for 'backend'... :) )
The solution, I believe, was to build a php 'middleman' on SERVER_A that simply passes data on to SERVER_B. Research shows me that file_get_contents is the tool for this.
So I take my original known-working PHP file, I put it on SERVER_B and rename it to "mongoPatch_backend.php".
<?php
$user = "xxxx";
$pwd = 'xxx';
$filter = [];
if (isset($_REQUEST['needleKey'])) {
$needleKey = $_REQUEST['needleKey'];
$needle = $_REQUEST['needle'];
$filter = [$needleKey => $needle];
}
$newData = $_REQUEST['newData'];
$filter = ['x' => ['$gt' => 1]];
$options = [
'projection' => ['_id' => 0],
'sort' => ['x' => -1],
];
$bson = MongoDB\BSON\fromJSON($newData);
$value = MongoDB\BSON\toPHP($bson);
$manager = new MongoDB\Driver\Manager("mongodb://${user}:${pwd}#SERVER_B:27017");
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->update(
[$needleKey => $needle],
['$set' => $value],
['multi' => false, 'upsert' => true]
);
$results = $manager->executeBulkWrite('sedwe.users', $bulk);
var_dump($results);
?>
On SERVER_A I then make a new file, dbPatch.php, like so:
<?php
$API = "https://SERVER_B/php/mongoPatch_backend.php?";
if (isset($_REQUEST['needleKey'])) {
$needleKey = $_REQUEST['needleKey'];
$needle = $_REQUEST['needle'];
$filter = [$needleKey => $needle];
}
$newData = $_REQUEST['newData'];
$postData = "needleKey=".urlencode($needleKey);
$postData .= "&needle=".urlencode($needle);
$postData .= "&newData=".urlencode($newData);
// echo $API.$postData;
$data = file_get_contents($API.$postData);
echo $data;
?>
But when I call it, I get nothing echo'd back out of $data.
Any idea why? Remember, the exact same call directly to mongoPatch_backend.php works just fine (but it's a CORS call, so it's not a valid option).
So here is what I've tried:
First, to ensure my AJAX call was still working, I spit out the response to the console. I get nothing.
So I changed the last line of the middleman (dbPatch.php) to echo "Hello World" instead of echo $data and received "Hello World" on the console as expected.
Next, I then changed the last line of my middleman (dbPatch.php) back to echo $data and tried reducing the 'backend' to a simple <?php echo "Hello Back World"; ?> and got nothing on the console.
Next, I go to https://SERVER_B/php/mongoPatch_backend.php in a browser ... and I'm greeted with "Hello Back World" as expected in the browser.
... which leads me to believe something is up with the transferring of info from server to server. Logical call, eh?
Unfortunately, when I try the same thing with just a 'fetch' command, it works perfectly fine:
Here is my 'middleman' (dbFetch.php) script on SERVER_A:
<?php
$API = "https://SERVER_B/php/mongoFetch_backend.php?";
$collection = $_REQUEST['collection'];
$postData = "collection=".urlencode($collection);
$needleID = $_REQUEST['needleID'];
$postData .= "&needleID=".urlencode($needleID);
$data = file_get_contents($API.$postData);
echo $data;
?>
And this is the file on the backend, SERVER_B:
<?php
$user = "xxxx";
$pwd = 'xxxx';
$filter = [];
if (isset($_REQUEST['needleID'])) {
$needleID = $_REQUEST['needleID'];
$filter = ['id'=> $needleID];
}
if (isset($_REQUEST['collection'])) {
$collection = $_REQUEST['collection'];
}
//Manager Class
$connection = new MongoDB\Driver\Manager("mongodb://${user}:${pwd}#SERVER_B:27017");
// Query Class
$query = new MongoDB\Driver\Query($filter);
$rows = $connection->executeQuery("db_name.$collection", $query);
// Convert rows to Array and send result back to client
$rowsArr = $rows->toArray();
echo json_encode($rowsArr);
?>
Huzzah, this works! ... and it's also proof there doesn't appear to be a problem with the server-to-server communication.
So back to ground zero.
I then go with a very simple newData value -- shorter, but same general layout - stringified json. It works! The data ends up in the database.
So I'm forced to think something is wrong with the data in newData (which is only a few hundred lines of stringified JSON made like this: encodeURIComponent(JSON.stringify(newData)). But, this bears repeating: this works if I skip the middleman.
... and that puts me at a loss. PHP isn't something I understand well... can you help?
EDIT to answer comment:
When I call mongoPatch_backend.php directly on SERVER_B it works (as stated above). I had it echo the $newData and it spits out a stringified JSON version of the variable (not URLencoded).
When I call dbPatch.php, it does not give me anything that was passed back from mongoPatch_backend.
As I said in the OP, if I modify mongoPatch_backend.php to do nothing other than echo "hellow world" I am still unable to log it to console when calling it via the above dbPatch.php file.
EDIT: I also tried putting the two PHP files on the same server and am getting the same results. (ie: both the dbPatch.php and mongoPatch.php files are in the same directory on the same server)
EDIT2: I have done a var_dump from the middleman and I get standard-looking human-readable stringified text back.
I do the same var_dump($_REQUEST['newData']); in the backend file and I get nothing back.
I have generated some XML which is saved to a file.
Dummy_Order.xml
In the following code I wanted to open the XML and use it in the method 'ImpOrders'
Here is my code
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
$proxy = new SoapClient('http://soapclient/wsdl/Web?wsdl', array ('trace' => 1));
if (file_exists('Dummy_Order.xml')) {
$xml = file_get_contents('Dummy_Order.xml');
} else {
exit('Failed to open XML.');
}
$xmlstring = new SimpleXMLElement($xml);
$result = $proxy->ImportOrders($xmlstring);
var_dump($result);
echo "REQUEST:\n" . $proxy->__getLastRequest() . "\n";
?>
I am getting a response in $result of 0 imported 0 skipped. So i then did getLastRequest() and it's adding the code from the Method but not adding my XML. It wants my XML in a string - which it current is in and isnt moaning about that (It does moan if i use it ->asXML).
I have tried
$result = $proxy->ImportOrders();
and
$result = $proxy->ImportOrders($xmlstring);
And both show the same result in _getLastRequest, which led me to believe that my string isn't being plugged in.
When I check the functions using _getFunctions it provides the information of this...
ImportResult ImportOrders(string $Orders)
Any help would be awesome!
Ok so i resolved it. All i needed to do was wrap my answer in <<
Like below.
$teststring = <<<XML
$xml
XML;
$result = $proxy->ImportOrders($teststring);
Hope this helps out anyone else using PHP, SoapClient and XML.
I'm trying to submit a signed XML document (with xmlseclibs), but the signature is turning itself to be wrong.
The code I'm using looks like this:
// input variables:
$tout = __DIR__ . "/" . $firmacert2;
$certBuffer = file_get_contents($tout);
$certTempFile = __DIR__ . '/temp/temp.xml';
$xmlBuffer = base64_decode($xmlstrBase64);
// document creation and loading
$doc = new DOMDocument();
$doc->loadXML($xmlBuffer);
$objDSig = new XMLSecurityDSig();
$objDSig->setCanonicalMethod(XMLSecurityDSig::EXC_C14N);
$objDSig->addReference($doc, XMLSecurityDSig::SHA1, array('http://www.w3.org/2000/09/xmldsig#enveloped-signature'));
$objKey = new XMLSecurityKey(XMLSecurityKey::RSA_SHA1, array('type' => 'private'));
// load private key
$objKey->passphrase = $pass;
$objKey->loadKey($tout, TRUE);
$objDSig->sign($objKey);
// Add associated public key
$objDSig->add509Cert($certBuffer);
$objDSig->appendSignature($doc->documentElement);
$doc->save($certTempFile);
$codif = file_get_contents($certTempFile);
$xml_base64 = base64_encode($codif);
$param1 = new SoapParam($xml_base64, 'xml');
$com = new SoapClient('https://www.aespd.es:443/agenciapd/axis/SolicitudService?wsdl', array('trace' => 1, 'encoding' => 'UTF-8'));
$respuesta2 = $com->probarXml($param1);
$respuesta = base64_decode($respuesta2);
And the xml is being sent, and that's nice, but when i recover the xml file, and check the signature on: http://www.aleksey.com/xmlsec/xmldsig-verifier.html
the error I'm getting is:
func=xmlSecOpenSSLEvpDigestVerify:file=digests.c:line=229:obj=sha1:subj=unknown:error=12:invalid data:data and digest do not match
I tried to transform the certificate into separate private and public keys, same file, different files, importing and exporting and such.
The flow goes this way:
Java program sends generated unsigned Base64 encoded XML to PHP file, which signs and sends it with a SoapClient, result is printed, then captured and interpreted by Java program, thus avoiding having individual certificates on the machines using this system.
I've ran into trouble with SOAP, I've never had this issue before and can't find any information on line that helps me solve it.
The following code
$wsdl = "path/to/my/wsdl";
$client = new SoapClient($wsdl, array('trace' => true));
//$$textinput is passed in and is a very large string with rows in <item></item> tags
$soapInput = new SoapVar($textinput, XSD_ANYXML);
$res = $client->dataprofilingservice(array("contents" => $soapInput));
$response = $client->__getLastResponse();
var_dump($res);//outputs null
var_dump($response);//provides the proper response as I would expect.
I've tried passing params into the SoapClient constructor to define soap version but that didnt' help. I've also tried it with the trace param set to false and not present which as expected made $response null but $res was still null. I've tried the code on both a linux and windows install running Apache.
The function definition in the WSDL is (xxxx is for security reasons)
<portType name="xxxxServiceSoap">
<operation name="dataprofilingservice">
<input message="tns:dataprofilingserviceSoapIn"/>
<output message="tns:dataprofilingserviceSoapOut"/>
</operation>
</portType>
I have it working using the __getLastResponse() but its annoying me it will not work properly.
I've put together a small testing script, does anyone see any issues here. Do I need a structure for the return type?
//very simplifed dataset that would normally be
//read in from a CSV file of about 1mb
$soapInput = getSoapInput("asdf,qwer\r\nzzxvc,ewrwe\r\n23424,2113");
$wsdl = "path to wsdl";
try {
$client = new SoapClient($wsdl,array('trace' => true,'exceptions' => true));
} catch (SoapFault $fault) {
$error = 1;
var_dump($fault);
}
try {
$res = $client->dataprofilingservice(array("contents" => $soapInput));
$response = $client->__getLastResponse();
echo htmlentities($client->__getLastRequest());//proper request echoed
echo '<hr>';
var_dump($res);//null
echo "<hr>";
echo(htmlentities($response));//proper response echoed
} catch (SoapFault $fault) {
$error = 1;
var_dump($fault);
}
function getSoapInput($input){
$rows = array();
$userInputs = explode("\r\n", $input);
$userInputs = array_filter($userInputs);
//
$inputTemplate = " <contents>%s</contents>";
$rowTemplate = "<Item>%s</Item>";
//
$soapString = "";
foreach ($userInputs as $row) {
// sanitize
$row = htmlspecialchars(addslashes($row));
$xmlStr = sprintf($rowTemplate, $row);
$rows[] = $xmlStr;
}
$textinput = sprintf($inputTemplate, implode(PHP_EOL, $rows));
$soapInput = new SoapVar($textinput, XSD_ANYXML);
return $soapInput;
}
Ok after much digging it is related to relative namespaces, it appears that PHP doesn't handle them well within the WSDL or the SOAP Envelope. So since I don't have control of the SOAP Server I will continue to get the response via __getLastResponse();.
Hopefully this will save some people some time it was hard to find.
You are mixing things here. __getLastResponse() returns the bare XML string response from the server if you make use of the 'trace' => true option. That is for debugging only.
So regardless whether 'trace' => true or not, the method which you would like to call originally returns the same and that is totally normal. Setting tracing to on won't change the behaviour, it just offers an additional feature, the return value for __getLastResponse().
As the SoapClient does not throw any exception I'd say that your call is going okay and NULL is a valid return value.
You might want to provide the actual XML string and/or the WSDL defintion so that one could inspect if that's the case or not.
