我正在从数据库创建一个XML文件。随后，我将获取该XML文件，并尝试将其发布到外部网站。在处理了与解析错误有关的严重问题后，我认识到这个问题是使用DOMDocument的结果，所以我将其转换为simpleXML。
我收到的错误是：Obj:SimpleXMLElement对象（[@attributes]=>数组（[Requence]=>检索查询字符串参数失败）引用=
//Save XML
$xmlDoc->save("file.xml");
//Convert DOMDocument to SimpleXML
$sxmlDoc = simplexml_load_file("file.xml");
print_r($sxmlDoc);
//Posting Order XML with PHP
$PartnerNumber = '1111';
$PartnerReference = $row['id'];
$OrderXml = '<Order Test="true">'.$sxmlDoc.'</Order>';
$urlConn = curl_init ("https://website.com/PostXmlOrder.axd?
PartnerNumber=".$PartnerNumber."&PartnerReference=".urlencode($PartnerReference));
curl_setopt ($urlConn, CURLOPT_POST, 1);
curl_setopt ($urlConn, CURLOPT_HTTPHEADER, array("Content-type", "text/xml"));
curl_setopt ($urlConn, CURLOPT_POSTFIELDS, $sxmlDoc);
curl_setopt ($urlConn, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($urlConn, CURLOPT_SSL_VERIFYPEER, 0);
$result = curl_exec($urlConn);
if (empty($result)) {
print "ERROR: " . curl_error($urlConn) . "'n";
exit;
}
// Parse the response
$xml = simplexml_load_string($result);
echo "Obj:'r'n";
print_r($xml);
echo "Reference=";
echo $xml->attributes()->Reference;
XML文件以SimpleXML格式输出到屏幕。有什么想法吗？
您正在免费执行一些额外的循环。
让我们回顾一下：您很可能需要将XML作为字符串POST，因此不需要将DOMDocument转换为SimpleXML，而只需将其作为字符串输出即可：
curl_setopt ($urlConn, CURLOPT_POSTFIELDS, $xmlDoc->saveXML());
参见DOMDocument::saveXML()。
注意不要将$xmlDoc转换为SimpleXMLElement，因此请从上面删除该代码。
// Create XML String
$xml = $xmlDoc->saveXML();
// Posting Order XML with Curl
$PartnerNumber = '1111';
$PartnerReference = $row['id'];
$url = sprintf(
"https://example.com/PostXmlOrder.axd?PartnerNumber=%s&PartnerReference=%s",
urlencode($PartnerNumber),
urlencode($PartnerReference)
);
$urlConn = curl_init($url);
curl_setopt_array(
$urlConn,
array(
CURLOPT_POST => 1,
CURLOPT_HTTPHEADER => array("Content-type", "text/xml"),
CURLOPT_POSTFIELDS => $xml,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_SSL_VERIFYPEER => 0,
)
);
$result = curl_exec($urlConn);
if (empty($result)) {
print "ERROR: " . curl_error($urlConn) . "'n";
exit;
}
// Parse the response
$sxml = simplexml_load_string($result);
echo "Obj:'r'n", print_r($sxml);
echo "Reference=", $sxml->attributes()->Reference;
