请求函数

function http_post ($url, $xml)
{
date_default_timezone_set('America/New_York');
$post_string = $xml;

$soap_do = curl_init();

完整回复

soap:ServerServer was unable to process request. ---> There was an error generating the XML document. ---> <>f__AnonymousType55`2[System.Int32,Z.T[]] cannot be serialized because it does not have a parameterless constructor.

      <currencyIds>
<string>EURUSD</string>
<string>USDCAD</string>
  </currencyIds>

根据你的wsdl，它是ArrayOfInt而不是ArrayOfString。

 <s:element name="GetProviderTrades">
   <s:complexType>
   <s:sequence>
   <s:element minOccurs="1" maxOccurs="1" name="providerId" type="s:int" /> 
   <s:element minOccurs="0" maxOccurs="1" name="currencyIds" type="tns:ArrayOfInt" /> 
   <s:element minOccurs="0" maxOccurs="1" name="fromDateStr" type="s:string" /> 
   <s:element minOccurs="0" maxOccurs="1" name="toDateStr" type="s:string" /> 
   <s:element minOccurs="1" maxOccurs="1" name="validTrades" type="s:boolean" /> 
   <s:element minOccurs="1" maxOccurs="1" name="lotSize" type="tns:LotSize" /> 
   <s:element minOccurs="1" maxOccurs="1" name="start" type="s:int" /> 
   <s:element minOccurs="1" maxOccurs="1" name="length" type="s:int" /> 
   <s:element minOccurs="0" maxOccurs="1" name="sortBy" type="s:string" /> 
   <s:element minOccurs="1" maxOccurs="1" name="sortAscending" type="s:boolean" /> 
   </s:sequence>
   </s:complexType>
 </s:element>

而ArrayOfInt是，

 <s:complexType name="ArrayOfInt">
 <s:sequence>
     <s:element minOccurs="0" maxOccurs="unbounded" name="int" type="s:int" /> 
 </s:sequence>
</s:complexType>

所以你的请求xml应该是这样的，

<currencyIds>
<int>11</int>
<int>22</int>
  </currencyIds>

cURL的SOAP请求给出了响应：生成XML文档时出错
