php - cURL 没有返回任何东西？

Question

<?php
error_reporting(-1);
$config = array
(
    "siteURL"        => "http://domain.com",
    "loginCheck"     => "checkuser.php",
    "userAgent"      => "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.204 Safari/534.16"
);

$postFields = "username=user&password=pass&submit= Login ";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $config['siteURL'] . $config['loginCheck']);
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_USERAGENT, config['userAgent']);
curl_setopt($ch, CURLOPT_REFERER, config['siteURL']);

$content = curl_exec($ch);
curl_close($ch);

echo $content;

?>

我希望这与 curl 的结果相呼应，但事实并非如此。我做错了什么吗？

确实如此，如果您设置一个完整的 URL 并在末尾添加“/”(修正其他两个拼写错误):

error_reporting(-1);
$config = array
(
    "siteURL"        => "http://www.apple.com/",
    "loginCheck"     => "checkuser.php",
    "userAgent"      => "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.204 Safari/534.16"
);

$postFields = "username=user&password=pass&submit= Login ";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $config['siteURL'] . $config['loginCheck']);
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $config['userAgent']);
curl_setopt($ch, CURLOPT_REFERER, $config['siteURL']);

$content = curl_exec($ch);
curl_close($ch);

echo $content;
