PHP, cURL，和HTTP POST的例子?

有人能告诉我如何用HTTP POST做一个PHP cURL吗?

我想这样发送数据:

username=user1, password=passuser1, gender=1

到www.example.com

我希望cURL返回result=OK这样的响应。有什么例子吗?

function curlPost($url, $data=NULL, $headers = NULL) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    if(!empty($data)){
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    }

    if (!empty($headers)) {
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    $response = curl_exec($ch);

    if (curl_error($ch)) {
        trigger_error('Curl Error:' . curl_error($ch));
    }

    curl_close($ch);
    return $response;
}


curlPost('google.com', [
    'username' => 'admin',
    'password' => '12345',
]);

如果表单使用重定向、身份验证、cookie、SSL (https)或其他任何东西，而不是期望POST变量的完全开放脚本，那么您将很快开始咬牙切齿。看看Snoopy，它完全按照您的想法来做，而且不需要设置大量的开销。

一个使用php curl_exec来做一个HTTP post的实例:

把它放在一个名为foobar.php的文件中:

<?php
  $ch = curl_init();
  $skipper = "luxury assault recreational vehicle";
  $fields = array( 'penguins'=>$skipper, 'bestpony'=>'rainbowdash');
  $postvars = '';
  foreach($fields as $key=>$value) {
    $postvars .= $key . "=" . $value . "&";
  }
  $url = "http://www.google.com";
  curl_setopt($ch,CURLOPT_URL,$url);
  curl_setopt($ch,CURLOPT_POST, 1);                //0 for a get request
  curl_setopt($ch,CURLOPT_POSTFIELDS,$postvars);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch,CURLOPT_CONNECTTIMEOUT ,3);
  curl_setopt($ch,CURLOPT_TIMEOUT, 20);
  $response = curl_exec($ch);
  print "curl response is:" . $response;
  curl_close ($ch);
?>

然后用php foobar.php命令运行它，它会将这样的输出转储到屏幕上:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" 
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Title</title>

<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">
<body>
  A mountain of content...
</body>
</html>

因此，您执行了一个PHP POST到www.google.com，并向其发送了一些数据。

如果服务器被编程为读入post变量，它可以基于此决定做一些不同的事情。

<?php
//
// A very simple PHP example that sends a HTTP POST to a remote site
//

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,"http://www.example.com/tester.phtml");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
            "postvar1=value1&postvar2=value2&postvar3=value3");

// In real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS, 
//          http_build_query(array('postvar1' => 'value1')));

// Receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($ch);

curl_close($ch);

// Further processing ...
if ($server_output == "OK") { ... } else { ... }
?>

下面是PHP + curl的一些样板代码 http://www.webbotsspidersscreenscrapers.com/DSP_download.php

包含在这些库中将简化开发

<?php
# Initialization
include("LIB_http.php");
include("LIB_parse.php");
$product_array=array();
$product_count=0;

# Download the target (store) web page
$target = "http://www.tellmewhenitchanges.com/buyair";
$web_page = http_get($target, "");
    ...
?>
