我遇到了一个相当奇怪的问题。
我正在尝试使用PHP的curl登录到远程MQ安装。
我有一个curl命令,该命令在终端中可以完美运行。
当我将同一个东西翻译成PHP时,它可以工作,但不能登录。通过终端成功登录的完全相同的值,以某种方式通过PHP触发了登录系统,但未登录。相反,它将再次返回登录页面。
我的cURL命令(数据部分已删除,因为它具有我的用户名和密码):
curl 'http://moodle.tsrs.org/login/index.php'

对应的PHP代码:
function login() {
$username = $_POST['username'];
$password = $_POST['password'];
if(!isset($_POST['username']) || !isset($_POST['password'])) {
echo "No login data received";
return;
}
$creq = curl_init();

curl_setopt_array($creq, array(

));
$output = curl_exec($creq);
echo print_r(curl_getinfo($creq));
echo "\n" . $output . "\n";
}
和curlinfo的输出:

有谁知道任何可能的原因吗?我尝试用COOKIEFILE和COOKIEJAR换出硬编码的cookie,但是它没有任何改变。
最佳答案
通过查看cURL实际完成的所有操作,可以更好地对其进行调试。这是通过将详细标志添加到命令-v
来完成的。
$ curl localhost/login [...] -v
通过添加
CURLOPT_VERBOSE
选项,我们可以从PHP的curl中获得相同的输出。请注意,通过添加此行,您正在指示cURL向STDOUT输出相同的信息-它不会返回,内容也不会发送到浏览器,因此必须在终端中对其进行调试。curl_setopt($curl, CURLOPT_VERBOSE, 1);
通过这种方式,您可以获得两个HTTP请求的一致且可比的输出,它看起来应该像这样:

左:问题中提供的命令行cURL(带有额外的
-v
标志)右:问题中张贴的PHP cURL(启用了
CURLOUT_VERBOSE
)如您所见,标题并不相同,这很清楚。 PHP调用缺少
Accept-Encoding
和Referer
header 。如果没有任何帮助,让我们尝试将PHP中的更多cURL设置更改回原始的cURL默认值。
Internally, PHP opts to override some defaults in cURL没有告诉你。尽管这些设置应该不错,但让我们通过将它们显式重置为cURL默认值来将它们更改回:
curl_setopt($curl, CURLOPT_DNS_CACHE_TIMEOUT, 60);
curl_setopt($curl, CURLOPT_DNS_USE_GLOBAL_CACHE, 0);
curl_setopt($curl, CURLOPT_MAXREDIRS, -1);
curl_setopt($curl, CURLOPT_NOSIGNAL, 0);
关于php - cURL可在Terminal上运行,但不能在PHP上运行,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/27088070/
