关于php：通过cURL传递$ _POST值

Passing $_POST values with cURL

如何使用cURL将$_POST值传递到页面？

应该可以正常工作。

$data = array('name' => 'Ross', 'php_master' => true);

// You can POST a file by prefixing with an @ (for <input type="file"> fields)
$data['file'] = '@/home/user/world.webp';

$handle = curl_init($url);
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
curl_exec($handle);
curl_close($handle)

我们在这里有两个选项，CURLOPT_POST用于打开HTTP POST，而CURLOPT_POSTFIELDS包含要提交的一系列发布数据。这可用于将数据提交到POST <form> s。

重要的是要注意，curl_setopt($handle, CURLOPT_POSTFIELDS, $data);以两种格式获取$ data，这决定了将如何编码帖子数据。

$data作为array()：数据将作为multipart/form-data发送，但服务器并不总是接受。

1 2	$data = array('name' => 'Ross', 'php_master' => true); curl_setopt($handle, CURLOPT_POSTFIELDS, $data);

$data作为url编码的字符串：数据将作为application/x-www-form-urlencoded发送，这是提交的html表单数据的默认编码。

1 2	$data = array('name' => 'Ross', 'php_master' => true); curl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($data));

我希望这可以帮助其他人节省时间。

请参阅：

curl_init
curl_setopt

Ross具有将常用参数/值格式发布到url的正确想法。

最近，我遇到了一种情况，我需要以内容类型" text / xml "的形式发布一些XML，而没有任何参数对，因此这是您的操作方式：

$xml = '<?xml version="1.0"?><stuff><child>foo</child><child>bar</child></stuff>';
$httpRequest = curl_init();

curl_setopt($httpRequest, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($httpRequest, CURLOPT_HTTPHEADER, array("Content-Type: text/xml"));
curl_setopt($httpRequest, CURLOPT_POST, 1);
curl_setopt($httpRequest, CURLOPT_HEADER, 1);

curl_setopt($httpRequest, CURLOPT_URL, $url);
curl_setopt($httpRequest, CURLOPT_POSTFIELDS, $xml);

$returnHeader = curl_exec($httpRequest);
curl_close($httpRequest);

就我而言，我需要从HTTP响应标头中解析一些值，因此您不一定需要设置CURLOPT_RETURNTRANSFER或CURLOPT_HEADER。

另一个使用cURL的简单PHP示例：

<?php
$ch = curl_init(); // Initiate cURL
$url ="http://www.somesite.com/curl_example.php"; // Where you want to post data
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true); // Tell cURL you want to post something
curl_setopt($ch, CURLOPT_POSTFIELDS,"var1=value1&var2=value2&var_n=value_n"); // Define what you want to post
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the output in string format
$output = curl_exec ($ch); // Execute

curl_close ($ch); // Close cURL handle

var_dump($output); // Show output
?>

可在此处找到示例：http：//devzone.co.in/post-data-using-curl-in-php-a-simple-example/

可以使用curl_setopt_array代替使用curl_setopt。

$query_string ="";

if ($_POST) {
$kv = array();
foreach ($_POST as $key => $value) {
$kv[] = stripslashes($key) ."=" . stripslashes($value);
}
$query_string = join("&", $kv);
}

if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}

$url = 'https://www.abcd.com/servlet/';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($kv));
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);

curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);

$result = curl_exec($ch);

curl_close($ch);

$url='Your url'; // Specify your url
$data= array('parameterkey1'=>value,'parameterkey2'=>value); // Add parameters in key value
$ch = curl_init(); // Initialize cURL
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
curl_close($ch);

查看cUrl PHP文档页面。它不仅对示例脚本有帮助。
