How to issue a SOAP request in PHP - php

Question

I am trying to issue a SOAP request in PHP. I have my service URL, and when I check it in SOAP UI, I can see the following
<application xmlns="http://somenamespace.com">
<doc xml:lang="en" title="https://someurl.com"/>
<resources base="https://someurl.com">
<resource path="sdk/user/session/logon/" id="Logon">
<doc xml:lang="en" title="Logon"/>
<param name="ApiKey" type="xs:string" required="false" default="" style="query" xmlns:xs="http://www.w3.org/2001/XMLSchema"/>
<param name="ApiSecret" type="xs:string" required="false" default="" style="query" xmlns:xs="http://www.w3.org/2001/XMLSchema"/>
<method name="POST" id="Logon">
<doc xml:lang="en" title="Logon"/>
<request>
<param name="method" type="xs:string" required="true" default="" style="query" xmlns:xs="http://www.w3.org/2001/XMLSchema"/>
<representation mediaType="application/json"/>
<representation mediaType="application/xml"/>
<representation mediaType="text/xml"/>
<representation mediaType="application/x-www-form-urlencoded"/>
</request>
<response status="404 500">
<representation mediaType="text/html; charset=utf-8" element="html"/>
</response>
<response status="">
<representation mediaType="application/json"/>
<representation mediaType="application/xml"/>
<representation mediaType="text/xml"/>
<representation mediaType="application/x-www-form-urlencoded"/>
</response>
<response status="500">
<representation mediaType="application/vnd.marg.bcsocial.result-v1.9+json; charset=utf-8" element="log:Fault" xmlns:log="https://someurl.com/sdk/user/session/logon"/>
<representation mediaType="application/vnd.marg.bcsocial.result-v1.9+xml; charset=utf-8" element="web:Result_1" xmlns:web="https://someurl.com/Sdk/WebService"/>
</response>
<response status="200">
<representation mediaType="application/vnd.marg.bcsocial.api.index.options.list-v2.6+xml; charset=utf-8" element="web:ListOfApiIndexOptions_4" xmlns:web="https://someurl.com/Sdk/WebService"/>
<representation mediaType="" element="data"/>
</response>
</method>
</resource>
</resources>
</application>
So I am trying to use this to log on. At the moment, I am trying something like the following
public function updateApi(){
$service_url = 'https://someurl.com/sdk/user/session/logon';
$curl = curl_init($service_url);
$curl_post_data = array(
"ApiKey" => 'somekey',
"ApiSecret" => 'somesecret',
);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
$curl_response = curl_exec($curl);
curl_close($curl);
var_dump($curl_response);
}
However, I always receive a fault response that the login has failed. Do I have to call the logon method or something?
Really just looking for some advice as to whether I am doing things correctly.
Thanks

Answer 1

You don't set the Content-Type header telling the format of the content you posted:
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/x-www-form-urlencoded'));
Otherwise, from php5 upwards, the usage of http_build_query is recommended:
$curl_post_data = array(
"ApiKey" => 'somekey',
"ApiSecret" => 'somesecret',
);
curl_setopt($curl, CURLOPT_POSTFIELDS,
http_build_query($curl_post_data));
Hope it helps you,

According the XML you should try to send your curl_post_data variable as a URL Encoded string. like urlencode('ApiKey=somekey&ApiSecret=somesecret') and secondly try to set the content-type of your request to 'application/x-www-form-urlencoded'

$service_url = 'https://someurl.com/sdk/user/session/logon';
$curl = curl_init($service_url);
$headers = ["Content-Type: application/json"]; // or other supported media type
$curl_post_data = array(
"ApiKey" => 'somekey',
"ApiSecret" => 'somesecret',
);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
curl_setopt($rest, CURLOPT_HTTPHEADER,$headers);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$curl_response = curl_exec($curl);
curl_close($curl);
