Question

我一直在写一些PHP脚本..

$gettarget = $argv[2];
echo "Trying to do something . . .\n";
            sleep(2);
            $ch = curl_init($gettarget); // initialize curl with given url
            $useragent = "Some user agent ";
            curl_setopt($ch, CURLOPT_USERAGENT, $useragent); // add useragent

            $response = curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // write the response to a variable
echo $response;
echo "Done";

所以这就是发生了什么，它来到“尝试做某事”然后没有任何事情发生，Done没有得到回应，这意味着卷曲有问题，我真的不知道cURL是什么，所以我以为我会在这里发帖。

Answer 1

您还没有在此代码块中执行curl。最后需要$response = curl_exec( $ch );。

    $gettarget = $argv[2];
    echo "Trying to do something . . .\n";

    sleep(2);
    $ch = curl_init($gettarget); // initialize curl with given url
    $useragent = "Some user agent ";
    curl_setopt($ch, CURLOPT_USERAGENT, $useragent); // add useragent

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // setopt() does not exec()

    // write the response to a variable
    $response = curl_exec( $ch );

    echo $response;
    echo "Done";

Answer 2

$response = curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

应该是

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);

curl_setopt()调用告诉它在您调用curl_exec()

时返回响应

cURL选项与php不兼容
