使用 php curl 将 XML 数据发送到 webservice

Question

I'm working on Flight API of arzoo. The server must receive the posted data in simple POST Request. To achieve this i'm using PHP cURL. In the API Document it is clearly mention that the data should be sent in the following format:

<AvailRequest>
        <Trip>ONE</Trip>
        <Origin>BOM</Origin>
        <Destination>NYC</Destination>
        <DepartDate>2013-09-15</DepartDate>
        <ReturnDate>2013-09-16</ReturnDate>
        <AdultPax>1</AdultPax>
        <ChildPax>0</ChildPax>
        <InfantPax>0</InfantPax>
        <Currency>INR</Currency>
        <Preferredclass>E</Preferredclass>
        <Eticket>true</Eticket>
        <Clientid>77752369</Clientid>
        <Clientpassword>*AB424E52FB5ASD23YN63A099A7B747A9BAF61F8E</Clientpassword>
        <Clienttype>ArzooINTLWS1.0</Clienttype>
        <PreferredAirline></PreferredAirline>
</AvailRequest>

I've taken the above code in a variable $xml. My PHP cURL code is as follows:

$URL = "http://59.162.33.102:9301/Avalability";

    //setting the curl parameters.
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL,$URL);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml'));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);

        if (curl_errno($ch)) 
    {
        // moving to display page to display curl errors
          echo curl_errno($ch) ;
          echo curl_error($ch);
    } 
    else 
    {
        //getting response from server
        $response = curl_exec($ch);
         print_r($response);
         curl_close($ch);
    }

I'm not getting anything in response. I've spoken about the same with the API Provider but they found empty request in their log. Am i missing something from my end. Your reply will be appreciated. Thank You.

After Struggling a bit with Arzoo International flight API, I've finally found the solution and the code simply works absolutely great with me. Here are the complete working code:

//Store your XML Request in a variable
    $input_xml = '<AvailRequest>
            <Trip>ONE</Trip>
            <Origin>BOM</Origin>
            <Destination>JFK</Destination>
            <DepartDate>2013-09-15</DepartDate>
            <ReturnDate>2013-09-16</ReturnDate>
            <AdultPax>1</AdultPax>
            <ChildPax>0</ChildPax>
            <InfantPax>0</InfantPax>
            <Currency>INR</Currency>
            <PreferredClass>E</PreferredClass>
            <Eticket>true</Eticket>
            <Clientid>777ClientID</Clientid>
            <Clientpassword>*Your API Password</Clientpassword>
            <Clienttype>ArzooINTLWS1.0</Clienttype>
            <PreferredAirline></PreferredAirline>
    </AvailRequest>';

Now I've made a little changes in the above curl_setopt declaration as follows:

    $url = "http://59.162.33.102:9301/Avalability";

        //setting the curl parameters.
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
// Following line is compulsary to add as it is:
        curl_setopt($ch, CURLOPT_POSTFIELDS,
                    "xmlRequest=" . $input_xml);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);
        $data = curl_exec($ch);
        curl_close($ch);

        //convert the XML result into array
        $array_data = json_decode(json_encode(simplexml_load_string($data)), true);

        print_r('<pre>');
        print_r($array_data);
        print_r('</pre>');

That's it the code works absolutely fine for me. I really appreciate @hakre & @Lucas For their wonderful support.

Previous anwser works fine. I would just add that you dont need to specify CURLOPT_POSTFIELDS as "xmlRequest=" . $input_xml "xmlRequest=" . $input_xml to read your $_POST. You can use file_get_contents('php://input') to get the raw post data as plain XML.

Check this one. It will work.

function fetch($i1,$i2,$i3,$i4)
{
$input_data = '<I> 
                <i1>'.$i1.'</i1> 
                <i2>'.$i2.'</i2> 
                <i3>'.$i2.'</i3> 
                <i4>'.$i3.'</i4> 
              </I>';
$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_PORT => "8080",
  CURLOPT_URL => "http://192.168.1.100:8080/avaliablity",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => $input_data,
  CURLOPT_HTTPHEADER => array(
    "Cache-Control: no-cache",
    "Content-Type: application/xml"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}
}

fetch('i1','i2','i3','i4');

If you are using shared hosting, then there are chances that outbound port might be disabled by your hosting provider. So please contact your hosting provider and they will open the outbound port for you
