在 php 中消耗 Restful 服务?

Question

我正在尝试使用以下代码使用Restful服务：

$dat=array(
'entidad' => "F001",'tipoIdentificacion' => 'CC','numeroIdentificacion' => '1020442757'
);
$postdata =http_build_query( $dat );

//print_r($postdata);
$opts = array('http' =>
array(
'method'  => 'POST',
'header'  => 'Content-Type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context  = stream_context_create($opts);
//var_dump($context);
$result=file_get_contents('http://172.18.131.195:9090/lince/rest/pazysalvo1/avaldescfin',FILE_USE_INCLUDE_PATH, $context);
//echo $result;
//$result = json_decode(file_get_contents('http://172.18.131.195:9090/lince/rest/pazysalvo1/avaldescfin?', false, $context),true);
print_r($result);

但它无法识别我发送的参数，因此返回空值：

{"entidad":"F001","tipoIdentificacion":null,"numeroIdentificacion":null,"codPersona":0,"estadoConsulta":"1","avales":[]}

我应该如何发送参数？

我不能以这种亚洲方式做到这一点，我以另一种方式给出了解决方案。

//set POST variables
$url = 'http://172.18.131.195:9090/lince/rest/pazysalvo1/avaldescfin';
$fields = array(
'entidad' => 'F001','tipoIdentificacion' =>$tipoid,'numeroIdentificacion' => $numid
);
//url-ify the data for the POST
foreach($fields as $key=>$value) 
{ 
$fields_string .= $key.'='.$value.'&'; 
}
rtrim($fields_string, '&');
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
$result=json_decode($result,true);
/*echo "<pre>";
print_r($result);
echo "</pre>";*/
