PHP+SOAP+Google API

help me!

[tnkywe]

Hi,
Firstly sorry for my english :)

I wrote simple code to comunicate with Google Server useing Google API (http://google.com/apis/):

<?php
$url='http://api.google.com/search/beta2';
$host='api.google.com';
$action='urn:GoogleSearchAction';
$request = '<'.'?xml version="1.0" encoding="ISO-8859-1"?'.'>
<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:typens="urn:GoogleSearch">
<SOAP-ENV:Body>
<typens:doGoogleSearch xmlns:typens="urn:GoogleSearch">
<key xsi:type="xsd:string">XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</key>
<q xsi:type="xsd:string">asdasd</q>
<start xsi:type="xsd:int">0</start>
<maxResults xsi:type="xsd:int">10</maxResults>
<filter xsi:type="xsd:boolean">true</filter>
<safeSearch xsi:type="xsd:boolean">false</safeSearch>
<lr xsi:type="xsd:string"></lr>
<ie xsi:type="xsd:string">latin</ie>
<oe xsi:type="xsd:string">latin</oe>
</typens:doGoogleSearch>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>';
$header[] = "Host: $host";
$header[] = "Accept: text/html;q=0.5, application/soap+xml";
$header[] = "Content-length: ".strlen($request);
$header[] = "Content-Type: text/xml";
$header[] = "Connection: close";
$header[] = "SOAPAction: $action\r\n";
$header[] = $request;
$ch = curl_init();
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'POST');
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); 
curl_setopt($ch, CURLOPT_HEADER, 1); 
$data=curl_exec($ch);
curl_close($ch);
print($data);
?>

But there are some errors, this is my output:

Welcome to WebmasterWorld, tnkywe.

What is your error?

I have PHP Version 4.1.2

The first thing I would do is get current. There have been a lot of security patches since that release!

[dmorison]

"No signature match" can occur when one (or more) of the data types are represented incorrectly, in other words the SOAP server doesn't know how to decode the value based on the specified xsi:type.

I quickly compared your request with the request generated by my Google API app using PHP5's built in SOAP library, and the only difference I could see was the encoding of the boolean values.

The required encoding is formalised by:
[schemas.xmlsoap.org...]

...which states that boolean is constrained to 0 or 1, not the strings true or false, so try changing the values for filter and safeSearch to 1 and 0 respectively (instead of true and false) and see if that works....
