总结PHP的6种GET和POST远程请求发送方法
1、用file_get_contents 以get方式获取内容:
<?php $url = 'http://www.phprm.com/'; $html = file_get_contents($url); echo $html;
2、用fopen打开url,用get方式获取
$fp = fopen($url, 'r');
stream_get_meta_data($fp);
while (!feof($fp)) {
$result.= fgets($fp, 1024);
}
echo "url body: $result";
fclose($fp);
3、用file_get_contents以post方式获取内容: $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 $html;4、用fsockopen函数打开url,以get方式获取完整的数据,包括header和body, fsockopen需要PHP.ini中allow_url_fopen选项开启
function get_url($url, $cookie = false) {
$url = parse_url($url);
$query = $url[path] . '?' . $url[query];
echo 'Query:' . $query;
$fp = fsockopen($url[host], $url[port] ? $url[port] : 80, $errno, $errstr, 30);
if (!$fp) {
return false;
} else {
$request = "GET $query HTTP/1.1\r\n";
$request.= "Host: $url[host]\r\n";
$request.= "Connection: Close\r\n";
if ($cookie) $request.= "Cookie: $cookie\n";
$request.= "\r\n";
fwrite($fp, $request);
while (!@feof($fp)) {
$result.= @fgets($fp, 1024);
}
fclose($fp);
return $result;
}
}//获取url的html部分,去掉header
function GetUrlHTML($url, $cookie = false) {
$rowdata = get_url($url, $cookie);
if ($rowdata) {
$body = stristr($rowdata, "\r\n\r\n");
$body = substr($body, 4, strlen($body));
return $body;
}
return false;
}5、用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body
function HTTP_Post($URL, $data, $cookie, $referrer = '') {
// parsing the given URL
$URL_Info = parse_url($URL);
// Building referrer
if ($referrer == '') // if not given use this script as referrer
$referrer = '111';
// making string from $data
foreach ($data as $key => $value) $values[] = '$key=' . urlencode($value);
$data_string = implode('&', $values);
// Find out which port is needed – if not given use standard (=80)
if (!isset($URL_Info['port'])) $URL_Info['port'] = 80;
// building POST-request:
$request.= "POST " . $URL_Info['path'] . " HTTP/1.1\n";
$request.= "Host: " . $URL_Info['host'] . "\n";
$request.= "Referer: $refere\r\n";
$request.= "Content-type: application/x-www-form-urlencoded\n";
$request.= 'Content-length: ' . strlen($data_string) . "\n";
$request.= "Connection: close\n";
$request.= "Cookie: $cookie\n";
$request.= "\n";
$request.= $data_string . "\n";
$fp = fsockopen($URL_Info['host'], $URL_Info['port']);
fputs($fp, $request);
while (!feof($fp)) {
$result.= fgets($fp, 1024);
}
fclose($fp);
return $result;
}6、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
$ch = curl_init(); $timeout = 5; curl_setopt($ch, CURLOPT_URL, 'http: //www.phprm.com/'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents = curl_exec($ch); curl_close($ch); echo $file_contents;
