谢谢你的剧本,哈克雷。由于我需要HTTP PUT,因此我用以下结果对其进行了扩展:
GET request ..........................................: Continue: No
GET request with empty header ........................: Continue: No
POST request with empty header .......................: Continue: Yes
POST request with expect continue explicitly set .....: Continue: Yes
POST request with expect (set to nothing) as well ....: Continue: Yes
POST request with expect continue from earlier removed: Continue: No
PUT request with empty header ........................: Continue: Yes
PUT request with expect continue explicitly set ......: Continue: Yes
PUT request with expect (set to nothing) as well .....: Continue: Yes
PUT request with expect continue from earlier removed : Continue: No
DELETE request with empty header .....................: Continue: Yes
DELETE request with expect continue explicitly set ...: Continue: Yes
DELETE request with expect (set to nothing) as well ..: Continue: Yes
DELETE request with expect continue from earlier removed : Continue: No
下面是脚本:
<?php
$ch = curl_init('http://www.iana.org/domains/example/');
function curl_exec_continue($ch) {
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
$continue = 0 === strpos($result, "HTTP/1.1 100 Continue\x0d\x0a\x0d\x0a");
echo "Continue: ", $continue ? 'Yes' : 'No', "\n";
return $result;
}
// --- GET
echo "GET request ..........................................: ", !curl_exec_continue($ch);
$header = array();
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "GET request with empty header ........................: ", !curl_exec_continue($ch);
// --- POST
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('hello'));
echo "POST request with empty header .......................: ", !curl_exec_continue($ch);
$header[] = 'Expect: 100-continue';
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "POST request with expect continue explicitly set .....: ", !curl_exec_continue($ch);
$header[] = 'Expect:';
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "POST request with expect (set to nothing) as well ....: ", !curl_exec_continue($ch);
unset($header[0]);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "POST request with expect continue from earlier removed: ", !curl_exec_continue($ch);
// --- PUT
curl_setopt($ch, CURLOPT_PUT, TRUE);
$header = array();
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "PUT request with empty header ........................: ", !curl_exec_continue($ch);
$header[] = 'Expect: 100-continue';
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "PUT request with expect continue explicitly set ......: ", !curl_exec_continue($ch);
$header[] = 'Expect:';
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "PUT request with expect (set to nothing) as well .....: ", !curl_exec_continue($ch);
unset($header[0]);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "PUT request with expect continue from earlier removed : ", !curl_exec_continue($ch);
// --- DELETE
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
$header = array();
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "DELETE request with empty header .....................: ", !curl_exec_continue($ch);
$header[] = 'Expect: 100-continue';
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "DELETE request with expect continue explicitly set ...: ", !curl_exec_continue($ch);
$header[] = 'Expect:';
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "DELETE request with expect (set to nothing) as well ..: ", !curl_exec_continue($ch);
unset($header[0]);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo "DELETE request with expect continue from earlier removed : ", !curl_exec_continue($ch);
