PHP：6种GET和POST请求发送方法

在i94web博客中，我试过了畅言和多说两种社会化评论框，后来还是抛弃了畅言，不安全。

无论是畅言还是多说，我都需要从远程抓取文章的评论数，然后存入本地数据库。对于多说，请求的格式如下：

// 获取评论次数,参数是文章ID
function getCommCount($postid)
{
    $jsondata = file_get_contents("http://api.duoshuo.com/threads/counts.json?short_name=i94web threads=$postid"); // 设置true返回数组,不设置或者是false则返回对象 $resjson= json_decode($jsondata,true); return $resjson[response][$postid][comments];
}

对于远程请求，有很多种方法。今天，LZ就搜罗了六种，供大家参考。

1、用file_get_contents 以get方式获取内容：

?php
$url=http://www.ido321.com/;
$html = file_get_contents($url);
echo $html;
?

2、用fopen打开url，用get方式获取

$data = http_build_query($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(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

$url = parse_url($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 $result;
}
}
//获取url的html部分，去掉header
function GetUrlHTML($url,$cookie=false)
{
$rowdata = get_url($url,$cookie);
if($rowdata)
{
$body= stristr($rowdata,rnrn);
$body=substr($body,4,strlen($body));
return $body;
}

return false;
}

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/1.1n"; $request.="Host: ".$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

curl_setopt ($ch, CURLOPT_URL, ‘http://www.ido321.com/);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);

echo $file_contents;
