well i wanted to make a simple webservice that searches the db and return the data i know i can do it with mysql connector but this is just to learn how to use soaps here is the code for php soap server
require_once ('lib/nusoap.php');
$namespace = "http://localhost/webservice/index.php?wsdl";
$server = new soap_server();
$server->configureWSDL("DBQuery");
$server->wsdl->schemaTargetNamespace = $namespace;
$server->register(
'QueryMsg',
array('name'=>'xsd:string'),
array('return'=>'xsd:string'),
$namespace,
false,
'rpc',
'encoded',
'returns data from database');
function QueryMsg($query)
{
$con=mysqli_connect('localhost','root','','webserivce');
if (mysqli_connect_errno()) {
return "Failed to connect to MySQL: " . mysqli_connect_error();
}
if(!isset($query) or strpos(strtolower($query),'select')<=-1)
{
return "invalid order";
}
else
{
mysqli_real_escape_string($con,$query);
$result = mysqli_query($con,$query);
while($row = mysqli_fetch_array($result)) {
$data[] = $row;}
return json_encode($data);
}
}
// create HTTP listener
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
exit();
?>
it works when i try calling it from a php soap client but when i try adding this http:// localhost /webservice/index.php in visual studio as service refernce to consume it from C# application i get an error here it is
The HTML document does not contain Web service discovery information.
Metadata contains a reference that cannot be resolved: 'http://localhost/webservice/index.php'.
The content type text/xml; charset=ISO-8859-1 of the response message does not match the content type of the binding (application/soap+xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 700 bytes of the response were: '<?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/">
<SOAP-ENV:Body><SOAP-ENV:Fault><faultcode xsi:type="xsd:string">SOAP-ENV:Client</faultcode><faultactor xsi:type="xsd:string"></faultactor><faultstring xsi:type="xsd:string">Operation '' is not defined in the WSDL for this service</faultstring><detail xsi:type="xsd:string"></detail></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope>'.
The remote server returned an error: (500) Internal Server Error.
If the service is defined in the current solution, try building the solution and adding the service reference again.
solved : well it was easy actually there is two ways either use WCF and change encoding to ISO-8859-1
or change encoding of the web service itself by adding this line $server->soap_defencoding = 'UTF-8';
after creating the soap server
