方法一：利用php的socket編程來直接給接口發(fā)送數(shù)據(jù)來模擬post的操作。

建立兩個文件post.php,getpost.php
post.php內(nèi)容如下：
<?php
 $flag = 0;
 $post = '';
 $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) {
        $post .= "&";
        $flag = 1;
    }
    $post.= $key."="; $post.= urlencode($value);
    $flag = 1;
    }
    $length = strlen($post);
     //創(chuàng)建socket連接
   $fp = fsockopen("localhost",81,$errno,$errstr,10) or exit($errstr."--->".$errno);
    //構(gòu)造post請求的頭
    $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 .= $post."\r\n";
    

    //發(fā)送post的數(shù)據(jù)
   fputs($fp,$header);
    $inheader = 1;
    while (!feof($fp)) {
        $line = fgets($fp,1024); //去除請求包的頭只顯示頁面的返回數(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
