在php中使用curl以编程方式发布到php网页并检索结果

Posted 2021-02-23

This source code contains two files:
1) result.php is a php webpage which expects a post request and renders some static results
2) mycurl.php uses curl to post programmatically some data to the result.php and after rendering the result is being return and saved inside a php variable. We later display inside the page this result

Note that in order to execute properly you should change the url inside curl_init inside the source code

mycurl.php:
 
<?php
 
$curl_connection = curl_init('http://george.pligor.com/testing/result.php');
 
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);	//seconds. Zero to wait indefinately
 
//curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");	//let's trick them by saying we are a mozilla agent ;)
curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
 
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);	//TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
 
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);	//FALSE to stop cURL from verifying the peer's certificate
 
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, true);	//TRUE to follow any "Location: " header that the server sends as part of the HTTP header (note this is recursive, PHP will follow as many "Location: " headers that it is sent, unless CURLOPT_MAXREDIRS is set)
 
curl_setopt($curl_connection, CURLOPT_POST, false);	//TRUE to do a regular HTTP POST. This POST is the normal application/x-www-form-urlencoded kind, most commonly used by html forms. 
 
 
$post_data["material"] = "1";
$post_data["Icc"] = "22";
 
foreach($post_data as $dataKey => $dataVal)
{
	$post_items[] = "$dataKey=$dataVal";
}
 
$post_string = implode("&",$post_items);
 
//$post_string = urlencode($post_string);
 
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);	//This parameter can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value
//curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_data);
 
$result = curl_exec($curl_connection);
 
//show information regarding the request
print "<pre>";
print_r(curl_getinfo($curl_connection));
print "</pre>";
 
print curl_errno($curl_connection) . '-' . curl_error($curl_connection);
 
curl_close($curl_connection);
 
?>

<?php

result.php:

	print "<br/><br/>";
