PHP常用发送get、post请求的几种方法

方法1: 用file_get_contents 以get方式获取内容

<?php
$url='http://www.domain.com/';
$html = file_get_contents($url);
echo $html;
?>

方法2：用file_get_contents函数,以post方式获取url

<?php
$data = array ('foo' => 'bar');
$data = http_build_query($data);

$opts = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencoded\r\n" .
"Content-Length: " . strlen($data) . "\r\n",
'content' => $data
)
);

$context = stream_context_create($opts);
$html = file_get_contents('http://localhost/e/admin/test.html', false, $context);

echo $html;
?>

方法3:使用curl库，使用curl库之前，可能需要查看一下php.ini是否已经打开了curl扩展

<?php
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, 'http://www.domain.com/');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);

echo $file_contents;
?>

方法4：使用CURL发送post请求

<?php
$ch = curl_init();
$timeout = 5;
$params="{\"id\":1,\"name\":\"test\"}";
curl_setopt ($ch, CURLOPT_URL, $URL); //发贴地址
curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-type: text/json'));//设置header属性
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_POST,true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
$file_contents = curl_exec($ch);//获得返回值
return $file_contents;
curl_close($ch);

?>
