今天非常需要这个问题的答案,因为不是每个人都想使用 cURL 来使用 Web 服务。PHP也允许使用以下代码进行此操作
function get_info()
{
$post_data = array(
'test' => 'foobar',
'okay' => 'yes',
'number' => 2
);
// Send a request to example.com
$result = $this->post_request('http://www.example.com/', $post_data);
if ($result['status'] == 'ok'){
// Print headers
echo $result['header'];
echo '<hr />';
// print the result of the whole request:
echo $result['content'];
}
else {
echo 'A error occured: ' . $result['error'];
}
}
function post_request($url, $data, $referer='') {
// Convert the data array into URL Parameters like a=b&foo=bar etc.
$data = http_build_query($data);
// parse the given URL
$url = parse_url($url);
if ($url['scheme'] != 'http') {
die('Error: Only HTTP request are supported !');
}
// extract host and path:
$host = $url['host'];
$path = $url['path'];
// open a socket connection on port 80 - timeout: 30 sec
$fp = fsockopen($host, 80, $errno, $errstr, 30);
if ($fp){
// send the request headers:
fputs($fp, "POST $path HTTP/1.1\r\n");
fputs($fp, "Host: $host\r\n");
if ($referer != '')
fputs($fp, "Referer: $referer\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ". strlen($data) ."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $data);
$result = '';
while(!feof($fp)) {
// receive the results of the request
$result .= fgets($fp, 128);
}
}
else {
return array(
'status' => 'err',
'error' => "$errstr ($errno)"
);
}
// close the socket connection:
fclose($fp);
// split the result header from the content
$result = explode("\r\n\r\n", $result, 2);
$header = isset($result[0]) ? $result[0] : '';
$content = isset($result[1]) ? $result[1] : '';
// return as structured array:
return array(
'status' => 'ok',
'header' => $header,
'content' => $content);
}
