本文实例讲述了PHP模拟http请求的方法。分享给大家供大家参考,具体如下:
方法一:利用php的socket编程来直接给接口发送数据来模拟post的操作。
建立两个文件post.php,getpost.php
post.php内容如下:
<?php
$flag = 0;
$params = "";
$errno = "";
$errstr = "";
//要post的数据
$argv = array(
"var1"=>"abc",
"var2"=>"how are you , my friend??");
//构造要post的字符串
foreach ($argv as $key=>$value) {
if ($flag!=0) {
$params .= "&";
$flag = 1;
}
$params.= $key."="; $params.= urlencode($value);
$flag = 1;
}
$length = strlen($params);
//创建socket连接
$fp = fsockopen("localhost",81,$errno,$errstr,10) or exit($errstr."--->".$errno);
//构造post请求的头
$header = "POST /flandy/getpost.php HTTP/1.1
";
$header .= "Host:127.0.0.1
";
$header .= "Referer:/flandy/post.php
";
$header .= "Content-Type: application/x-www-form-urlencoded
";
$header .= "Content-Length: ".$length."
";
$header .= "Connection: Close
";
//添加post的字符串
$header .= $params."
";
//发送post的数据
fputs($fp,$header);
$inheader = 1;
while (!feof($fp)) {
$line = fgets($fp,1024); //去除请求包的头只显示页面的返回数据
if ($inheader && ($line == "
" || $line == "
")) {
$inheader = 0;
}
if ($inheader == 0) {
echo $line;
}
}
fclose($fp);
?>
getpost.php的内容如下:
<?php echo "this is the data posted"; echo "<pre>"; print_r($_REQUEST); echo "</pre>"; ?>
结果输出:
this is the data posted Array ( [var1] => abc [var2] => how are you , my friend?? )
以上代码在本机81端口下已经通过测试。
方法二:使用PHP的curl扩展或HttpClient.class.php类,这两个非常类似,下面简单的列出curl的实现代码。
两个文件post2.php和getpost2.php
post2.php的内容如下:
<?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);//不直接输出,返回到变量
$curl_result = curl_exec($ch);
$result = explode(",", $curl_result);
curl_close($ch);
print_r($result);
?>
getpost2.php的内容如下:
<?php echo "returndata<br>"; echo "<pre>"; print_r($_REQUEST); echo "</pre>"; ?>
结果输出:
Array ( [0] => returndata Array ( [web] => "wwwbaiducom" [pwd] => 123456 [action] => check [pseid] => "NDE005" [amt] => 1 ) )
方法三:这个要借助第三方类库HttpClient
可以到这里下载:http://scripts.incutio.com/httpclient/
或者点击此处本站下载。
<?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);
?>
