PHP 对 navision 网络服务的 SOAP 请求
PHP SOAP request to navision webservice
几天来，我一直在努力在 PHP 网店和具有 NTLM 身份验证的 navision 服务器之间建立连接。现在连接和身份验证已完成，我在执行正确请求时遇到了问题。
对于这个例子，我尝试使用一个函数 (ItemPriceDiscInventory) 来检索价格信息。
我从客户那里得到的 url 是：http://IP:PORT/MSIteminfoTest/WS/Saniceve%20BV/Codeunit/ItemPriceDiscInventory
我尝试了两种方法来发出请求：
curl post 与原始 XML
原始XML由客户提供。这与输入（本地）WSDL 文件时测试程序 (SOACleaner) 给我的 XML 相同。
$request = '
<InputItemPriceDiscInventory_PortGetPriceDiscInvInformation xmlns="http://xyrow.com">
<Body xmlns="">
<GetPriceDiscInvInformation xmlns="urn:microsoft-dynamics-schemas/codeunit/ItemPriceDiscInventory">
<itemPriceDiscInventory>
<Item xmlns="urn:microsoft-dynamics-nav/xmlports/x50005">
<Klantnummer />
<Artikelnr />
<Aantal />
<KortingsPercentage1 />
<KortingsPercentage2 />
<NettoPerEenheid />
<BeschikbareVoorraad />
<WebShopVoorraad />
</Item>
</itemPriceDiscInventory>
<customerNo>1234</customerNo>
<itemNo>5678</itemNo>
<quantityVarDec>1</quantityVarDec>
</GetPriceDiscInvInformation>
</Body>
</InputItemPriceDiscInventory_PortGetPriceDiscInvInformation>';
我的要求：
$ch = curl_init();
$headers = array(
'Method: POST',
'Connection: Keep-Alive',
'Content-Type: text/xml; charset=utf-8',
"Host: {$ip}:{$port}",
"Accept: */*"
);
curl_setopt($ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
curl_setopt($ch, CURLOPT_USERPWD, 'usr:pass');
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM );
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_FAILONERROR, 0);
这个 returns WSDL 文件，无论我包含什么 POST 值。如果我包含 header 'SOAPAction: "ItemPriceDiscInventory"' 它会给我错误：
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><s:Fault><faultcode xmlns:a="urn:microsoft-dynamics-schemas/error">a:System.Net.WebException</faultcode><faultstring xml:lang="nl-NL">Soap message is invalid!</faultstring><detail><string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">Soap message is invalid!</string></detail></s:Fault></s:Body></s:Envelope>

PHP SoapClient 请求
好吧，我想，试试 PHP 的 SOAP 功能。我使用了 NTLMSoapClient class 进行身份验证，这似乎没问题。
如果我用WSDL方式构建客户端，用上面给出的URL，它无法解析WSDL:
[WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'URL' : Start tag expected, '<'
但如果我在非 WSDL 模式下执行此操作，并在参数中给出位置，我会得到一些结果...
stream_wrapper_unregister('http');
stream_wrapper_register('http', 'MyServiceProviderNTLMStream') or die("Failed to register protocol");
$client = new MyServiceNTLMSoapClient(null,array( 'location' => $url,
'uri' => "http://schemas.xmlsoap.org/wsdl/soap/",
'trace' => 1));
$itemPriceDiscInventory = array(
"Item" => array(
"Klantnummer" => null,
"Artikelnr" => null,
"Aantal" => null,
"KortingsPercentage" => null,
"NettoPerEenheid" => null,
"Voorraad" => null
)
);
$params = array(
"itemPriceDiscInventory" => $itemPriceDiscInventory,
"customerNo" => '0000265',
"itemNo" => 'SAN483539',
"quantityVarDec" => '1.0'
);
echo $client->GetPriceDiscInvInformation($params);
stream_wrapper_restore('http');
这会导致错误。如果我收到最后的请求和响应，它会给我：

所以，看起来他正在尝试解析它，但是请求的格式不正确。注意：我不知道 uri 参数必须是什么。这是我可以从 WSDL 中读取的内容吗？
如果我看一下客户给我的请求和 SOAP 请求，它有很大的不同（第一个看起来根本不像 SOAP），但是对于 SOAP 请求，似乎是我再靠近一点。
对此有什么想法吗？
我终于明白了。首先我认为我的请求中的命名空间有问题。
我把WSDL文件保存在自己的服务器上，以WSDL方式用于soapclient，以navision服务器为位置。这奏效了！
我不知道为什么我不能在 WSDL 模式下使用直接 URL，但这是一个可以接受的解决方法。
