本文實(shí)例講述了PHP模擬http請(qǐng)求的方法。分享給大家供大家參考,具體如下:
方法一:利用php的socket編程來(lái)直接給接口發(fā)送數(shù)據(jù)來(lái)模擬post的操作。
建立兩個(gè)文件post.php,getpost.php
post.php內(nèi)容如下:
<?php $flag = 0; $params = ''; $errno = ''; $errstr = ''; //要post的數(shù)據(jù) $argv = array( 'var1'=>'abc', 'var2'=>'how are you , my friend??'); //構(gòu)造要post的字符串 foreach ($argv as $key=>$value) { if ($flag!=0) { $params .= "&"; $flag = 1; } $params.= $key."="; $params.= urlencode($value); $flag = 1; } $length = strlen($params); //創(chuàng)建socket連接 $fp = fsockopen("localhost",81,$errno,$errstr,10) or exit($errstr."--->".$errno); //構(gòu)造post請(qǐng)求的頭 $header = "POST /flandy/getpost.php HTTP/1.1\r\n"; $header .= "Host:127.0.0.1\r\n"; $header .= "Referer:/flandy/post.php\r\n"; $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; $header .= "Content-Length: ".$length."\r\n"; $header .= "Connection: Close\r\n\r\n"; //添加post的字符串 $header .= $params."\r\n"; //發(fā)送post的數(shù)據(jù) fputs($fp,$header); $inheader = 1; while (!feof($fp)) { $line = fgets($fp,1024); //去除請(qǐng)求包的頭只顯示頁(yè)面的返回?cái)?shù)據(jù) if ($inheader && ($line == "\n" || $line == "\r\n")) { $inheader = 0; } if ($inheader == 0) { echo $line; } } fclose($fp); ?>
getpost.php的內(nèi)容如下:
<?php echo "this is the data posted"; echo "<pre>"; print_r($_REQUEST); echo "</pre>"; ?>
結(jié)果輸出:
this is the data posted Array ( [var1] => abc [var2] => how are you , my friend?? )
以上代碼在本機(jī)81端口下已經(jīng)通過(guò)測(cè)試。
方法二:使用PHP的curl擴(kuò)展或HttpClient.class.php類,這兩個(gè)非常類似,下面簡(jiǎn)單的列出curl的實(shí)現(xiàn)代碼。
兩個(gè)文件post2.php和getpost2.php
post2.php的內(nèi)容如下:
<?php $psecode = 'NDE005'; $website = 'www.baidu.com'; $amt = 1; $pwd = 123456; $ch = curl_init(); $curl_url = "http://localhost:81/flandy/getpost2.php?web=" . $website . "&pwd=" . $pwd . "&action=check&pseid=" . $psecode . "&amt=" . $amt; curl_setopt($ch, CURLOPT_URL, $curl_url); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//不直接輸出,返回到變量 $curl_result = curl_exec($ch); $result = explode(',', $curl_result); curl_close($ch); print_r($result); ?>
getpost2.php的內(nèi)容如下:
<?php echo "returndata<br>"; echo "<pre>"; print_r($_REQUEST); echo "</pre>"; ?>
結(jié)果輸出:
Array ( [0] => returndata Array ( [web] => 'wwwbaiducom' [pwd] => 123456 [action] => check [pseid] => 'NDE005' [amt] => 1 ) )
方法三:這個(gè)要借助第三方類庫(kù)HttpClient
可以到這里下載:http://scripts.incutio.com/httpclient/
或者點(diǎn)擊此處本站下載。
<?php require_once 'HttpClient.class.php'; $params = array('web' => 'www.baidu.com', 'pwd' => '123456', 'action' => 'check', 'pseid' => 'NDE005', 'amt' => 1); $pageContents = HttpClient::quickPost('http://localhost:81/flandy/getpost3.php', $params); $result = explode(',', $pageContents); print_r($result); ?>
