HttpRequest::send — Enviar petición

Descripción

public HttpMessage HttpRequest::send ( void )

A pesar de que puede lanzarse una excepción, la transferencia podría haber tenido éxito al menos parcialmente, por lo que quizás desee comprobar los valores devueltos por varias llamadas al método HttpRequest::getResponse*().

Valores devueltos

Devuelve en forma de objeto HttpMessage la respuesta recibida.

Errores/Excepciones

Lanza HttpRuntimeException, HttpRequestException, HttpMalformedHeaderException, HttpEncodingException.

Ejemplos

Ejemplo #1 ejemplo GET


<?php
$r = new HttpRequest('http://example.com/feed.rss', HttpRequest::METH_GET);
$r->setOptions(array('lastmodified' => filemtime('local.rss')));
$r->addQueryData(array('category' => 3));
try {
    $r->send();
    if ($r->getResponseCode() == 200) {
        file_put_contents('local.rss', $r->getResponseBody());
    }
} catch (HttpException $ex) {
    echo $ex;
}
?>

Ejemplo #2 Ejemplo POST


<?php
$r = new HttpRequest('http://example.com/form.php', HttpRequest::METH_POST);
$r->setOptions(array('cookies' => array('lang' => 'de')));

Example how to use HttpRequest to post data and receive the response:
<?php
//set up variables
$theData = '<?xml version="1.0"?>
<note>
    <to>php.net</to>
    <from>lymber</from>
    <heading>php http request</heading>
    <body>i love php!</body>
</note>';
$url = 'http://www.example.com';
$credentials = 'user@example.com:password';
$header_array = array('Expect' => '',
                'From' => 'User A');
$ssl_array = array('version' => SSL_VERSION_SSLv3);
$options = array(headers => $header_array,
                httpauth => $credentials,
                httpauthtype => HTTP_AUTH_BASIC,
                protocol => HTTP_VERSION_1_1,
                ssl => $ssl_array);
                
//create the httprequest object                
$httpRequest_OBJ = new httpRequest($url, HTTP_METH_POST, $options);
//add the content type
$httpRequest_OBJ->setContentType = 'Content-Type: text/xml';
//add the raw post data
$httpRequest_OBJ->setRawPostData ($theData);
//send the http request
$result = $httpRequest_OBJ->send();
//print out the result
echo "<pre>"; print_r($result); echo "</pre>";
?>

There is a typo in Lymber's comment.
Instead of 
$httpRequest_OBJ->setContentType = 'Content-Type: text/xml';
use
$httpRequest_OBJ->setContentType('text/xml');

The HttpRequest class does support redirects, but it's disabled by default. To enable redirect do something like this:
<?php
// Set number of redirects to a reasonable number.
$r->setOptions(array('redirect' => 10));
?>

Note that send() does not process redirects, and there doesn't appear to any way to get this to happen automatically.  If you need to follow redirects, use something like the following code:

<?php
$request = new HttpRequest($url, HTTP_METH_GET);
do {
    $response = $request->send();
    if ($response->getResponseCode() != 301 && $response->getResponseCode() != 302) break;
    $request->setUrl($response->getHeader("Location"));
} while (1);
?>
