Question

的XML

$xml = "<?xml version='1.0' encoding='utf-8'?> 
<soap12:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap12='http://www.w3.org/2003/05/soap-envelope'> 
    <soap12:Body> 
    <GetProviderTrades xmlns='ZuluTrade.WebServices'> 
     <providerId>128391</providerId> 
     <currencyIds> 
    <string>EURUSD</string> 
    <string>USDCAD</string> 
     </currencyIds> 
     <fromDateStr>1986-08-27T09:00:00</fromDateStr> 
     <toDateStr>2014-01-12T09:00:00</toDateStr> 
     <validTrades>true</validTrades> 
     <lotSize>Standard</lotSize> 
     <start>0</start> 
     <length>20</length> 
     <sortBy>dc</sortBy> 
     <sortAscending>false</sortAscending> 
    </GetProviderTrades> 
    </soap12:Body> 
</soap12:Envelope>"; 

請求函數

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

$soap_do = curl_init(); 
curl_setopt($soap_do, CURLOPT_URL,   $url); 
curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10); 
curl_setopt($soap_do, CURLOPT_TIMEOUT,  10); 
curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false); 
curl_setopt($soap_do, CURLOPT_POST,   true); 
curl_setopt($soap_do, CURLOPT_POSTFIELDS, $post_string); 
curl_setopt($soap_do, CURLOPT_HTTPHEADER,  array('Content-Type: text/xml; charset=utf-8', 'Content-Length: '.strlen($post_string))); 
//curl_setopt($soap_do, CURLOPT_USERPWD, $user . ":" . $password); 

$result = curl_exec($soap_do); 
$err = curl_error($soap_do); 

return $result; 
} 

呼叫

$postRequest = http_post('http://www.zulutrade.com/WebServices/Performance.asmx?op=GetProviderTrades',$xml); 

充分反應

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.

有沒有發現什麼毛病我在做什麼，什麼想法？

Answer 1

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

根據你的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> 

而且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，你的請求XML應該是這樣的，

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