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);
?>
