PHP SOAP - 如何将XML传输到Web服务?
问题描述:
我了解到SOAP是向wsdl Web服务发送信息的有用PHP库。我正在构建一个XML表格以发送到web服务。我的朋友制作了网络服务,他说这需要一串字符。我试图给他发送一个XML表单的字符串,当他复制粘贴XML时,这是正确的,但是当我尝试使用Web服务时,他所得到的只是一个空指针。PHP SOAP - 如何将XML传输到Web服务?
while($row=mysql_fetch_array($result))
{
//Product Id is called ProductID in the XML
$product_id = $row['product_id'];
//Final price is called SalesPrice in the XML
$final_price = $row['final_price'];
echo $final_price.'<br>';
//qty is called Quantity in the XML
$qty = $row['qty'];
echo $qty.'<br>';
//Purchase cost is called PurchaseCost in the XML
$purchase_cost = $row['purchase_cost'];
echo $purchase_cost.'<br>';
$xml_output .="<SalesOrderLine>";
$xml_output.='<ProductID>'.$product_id.'</ProductID>';
$xml_output.='<Quantity>'.$qty.'</Quantity>';
$xml_output.='<SalesPrice>'.$final_price.'</SalesPrice>';
$xml_output.='<PurchaseCost>'.$purchase_cost.'</PurchaseCost>';
// Escaping illegal characters
$xml_output.='</SalesOrderLine>';
//$amount = $amount + $final_price;
//$i++;
}
$xml_output .="</SalesOrder>";
$xml = new SimpleXMLElement($xml_output);
$xml->asXML();
echo $xml;
try {
$client = new SoapClient("http://*&#^%(@%(*#(#$%)%CreateDB?wsdl");
$result = $client->addSalesOrder($xml);
} catch (SoapFault $e) {
var_dump(libxml_get_last_error());
var_dump($e);
}
//$result = $client->addSalesOrder($xml_output);
if (is_soap_fault($result)) {
trigger_error("SOAP Fault: (faultcode: {$result->faultcode}, faultstring: {$result->faultstring})", E_USER_ERROR);
}
当我回显出整个$ xml_output字符串时,我可以通过检查代码来看到它成为一个XML表。无论是否使用SimpleXML库,将该函数传递给Web服务都不起作用。如何安全地将字符串传输到作为XML表的Web服务,同时将其保留为字符串?
答
无法将XML作为Soap函数的参数发送。如果你想操作XML作为输入,使用以下方式
// xml content
$xmlDocument = '<Result>
<Product id="12345" language="fr-BE">
<Data>
<Brand>BrandName</Brand>
<ProductName>Bag</ProductName>
</Data>
</Product>
</Result>';
// initiate soap client
ini_set("soap.wsdl_cache_enabled", "0");
$client = new SoapClient(
"http://dotnetwebservice.com/Products.asmx?wsdl",
array(
'trace' => 1,
'exceptions' => 1,
'soap_version' => SOAP_1_1,
'encoding' => 'ISO-8859-1',
'features' => SOAP_SINGLE_ELEMENT_ARRAYS
)
);
$xmlvar = new SoapVar(
"<ns1:xmlDocument>'.$xmlDocument.'</ns1:xmlDocument>", XSD_ANYXML
);
$params->xmlDocument = (object)$xmlvar;
$save_result = $client->SaveProduct($params);
更多的细节你为什么要创建一个字符串,一个SimpleXMLElement,然后立刻把它放回一个字符串? ...我想你需要把它分配给一些变量来实际执行,例如$ strXML = $ xml-> asXML() – Onheiron 2012-07-30 13:17:11
