callable $callback)Set client debugging callback.
NOTE:
This method has been added in v2.6.0, resp. v3.1.0.
callable $callback# as function(http\Client $c#, http\Client\Request $r#, int $type#, string $data#)callback. For $type see http\Client::DEBUG_* constants.
<?php
(new http\Client)->setDebug(function($c, $r, $type, $data) {
if ($type === http\Client::DEBUG_INFO) {
printf("INFO: %s\n", $data);
} else {
repeat:
if ($type & http\Client::DEBUG_OUT) {
$sep = ">";
} elseif ($type & http\Client::DEBUG_IN) {
$sep = "<";
}
if ($type & http\Client::DEBUG_SSL) {
printf("%s <%d bytes of SSL data>\n", $sep, strlen($data));
} else {
printf("%s %s\n", $sep, str_replace("\n", "\n$sep ", rtrim($data, "\n")));
}
}
})->enqueue(new http\Client\Request("GET", "http://example.com"))->send();
?>
NOTE:
Except for http\Client::DEBUG_INFO, which always occurs separately, the debugcallback's $type argument contains a bitmask of (http\Client::DEBUG_IN or http\Client::DEBUG_OUT) and (http\Client::DEBUG_HEADER or http\Client::DEBUG_BODY or http\Client::DEBUG_SSL).
