Passing $_POST values with cURL
提问by Scott Gottreu
How do you pass $_POSTvalues to a page using cURL?
您如何$_POST使用将值传递给页面cURL？
回答by Ross
Should work fine.
应该工作正常。
$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.jpg';
$handle = curl_init($url);
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
curl_exec($handle);
curl_close($handle)
We have two options here, CURLOPT_POSTwhich turns HTTP POST on, and CURLOPT_POSTFIELDSwhich contains an array of our post data to submit. This can be used to submit data to POST<form>s.
我们在这里有两个选项，CURLOPT_POST打开 HTTP POST，并CURLOPT_POSTFIELDS包含要提交的帖子数据数组。这可用于向POST<form>s提交数据。
It is important to note that curl_setopt($handle, CURLOPT_POSTFIELDS, $data);takes the $data in two formats, and that this determines how the post data will be encoded.
需要注意的是curl_setopt($handle, CURLOPT_POSTFIELDS, $data);，$data 有两种格式，这决定了 post 数据的编码方式。
$dataas anarray(): The data will be sent asmultipart/form-datawhich is not always accepted by the server.$data = array('name' => 'Ross', 'php_master' => true); curl_setopt($handle, CURLOPT_POSTFIELDS, $data);$dataas url encoded string: The data will be sent asapplication/x-www-form-urlencoded, which is the default encoding for submitted html form data.$data = array('name' => 'Ross', 'php_master' => true); curl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($data));
$dataas anarray()：数据将被发送，multipart/form-data服务器并不总是接受它。$data = array('name' => 'Ross', 'php_master' => true); curl_setopt($handle, CURLOPT_POSTFIELDS, $data);$data作为 url 编码字符串：数据将作为 发送application/x-www-form-urlencoded，这是提交的 html 表单数据的默认编码。$data = array('name' => 'Ross', 'php_master' => true); curl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($data));
I hope this will help others save their time.
我希望这会帮助其他人节省时间。

Ross has the right ideafor POSTing the usual parameter/value format to a url.
I recently ran into a situation where I needed to POST some XML as Content-Type "text/xml" without any parameter pairs so here's how you do that:
我最近遇到了一种情况，我需要将一些 XML 作为 Content-Type "text/xml" 发布而没有任何参数对，因此您可以这样做：
$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);
In my case, I needed to parse some values out of the HTTP response header so you may not necessarily need to set CURLOPT_RETURNTRANSFERor CURLOPT_HEADER.
就我而言，我需要从 HTTP 响应标头中解析一些值，因此您可能不一定需要设置CURLOPT_RETURNTRANSFER或CURLOPT_HEADER。

$query_string = "";
if ($_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);

Another simple PHP example of using cURL:
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
?>
Example found here: http://devzone.co.in/post-data-using-curl-in-php-a-simple-example/
在这里找到的例子：http: //devzone.co.in/post-data-using-curl-in-php-a-simple-example/
Instead of using curl_setoptyou can use curl_setopt_array.
而不是使用curl_setopt您可以使用curl_setopt_array。

Check out the cUrl PHP documentation page. It will help much more than just with example scripts.
查看cUrl PHP 文档页面。它将不仅仅是示例脚本的帮助。
