PHP的GET和POST請求發(fā)送方法
在i94web博客中，我試過了暢言和多說兩種社會化評論框，后來還是拋棄了暢言，不安全。無論是暢言還是多說，我都需要從遠程抓取文章的評論數，然后存入本地數據庫。對于多說，請求的格式如下，就跟隨小編去了解下吧，想了解更多相關信息請 持續(xù)關注我們應屆畢業(yè)生考試網!
/pic/strong>
function getCommCount($postid)
{
$jsondata = file_get_contents("/pic/threads/counts.json?short_name=i94web&threads=$postid"); /pic/p>
}
對于遠程請求，有很多種方法。今天，LZ就搜羅了六種，供大家參考。
1、用file_get_contents 以get方式獲取內容：
<?php
$url='/pic/';
$html = file_get_contents($url);
echo $html;
?>
2、用fopen打開url，用get方式獲取
$fp = fopen($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方式獲取內容：
$data = array ('foo' => 'bar');
$data = http_build_query($data);
$opts = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencodedrn" . 'Content-Length: ' . strlen($data) . 'rn', 'content' => $data ) ); $context = stream_context_create($opts); $html = file_get_contents('/pic/e/admin/test.html', false, $context); echo $html;
4、用fsockopen函數打開url，以get方式獲取完整的數據，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 選項開啟
function get_url ($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/1.1rn';
$request .= 'Host: $url[host]rn';
$request .= 'Connection: Closern';
if($cookie) $request.='Cookie: $cookien';
$request.='rn';
fwrite($fp,$request);
while(!@feof($fp)) {
$result .= @fgets($fp, 1024);
}
fclose($fp);
return $result;
}
}
/pic/p>
function GetUrlHTML($url,$cookie=false)
{
$rowdata = get_url($url,$cookie);
if($rowdata)
{
$body= stristr($rowdata,'rnrn');
$body=substr($body,4,strlen($body));
return $body;
}
return false;
}
5、用fsockopen函數打開url，以POST方式獲取完整的數據，包括header和body
function HTTP_Post($URL,$data,$cookie, $referrer='')
{
/pic/p>
$URL_Info=parse_url($URL);
/pic/p>
if($referrer=='') /pic/p>
$referrer='111';
/pic/p>
foreach($data as $key=>$value)
$values[]='$key='.urlencode($value);
$data_string=implode('&',$values);
/pic/p>
if(!isset($URL_Info['port']))
$URL_Info['port']=80;
/pic/p>
$request.="POST ".$URL_Info['path']." HTTP/1.1n"; $request.="Host: ".$URL_Info['host']."n"; $request.="Referer: $referern"; $request.="Content-type: application/x-www-form-urlencodedn"; $request.='Content-length: '.strlen($data_string)."n"; $request.='Connection: closen'; $request.='Cookie: $cookien'; $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庫，使用curl庫之前，可能需要查看一下php.ini是否已經打開了curl擴展
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, ‘/pic/');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
