Question

我有一个交易，其中file1.php curl运行file2.php。 file2.php是一个长时间运行的文件，但是它会将响应发送（或者应该发送）给file1.php，然后继续执行它的代码。我正在使用输出缓冲区来尝试发送这些数据，但问题是如果我'返回';冲洗后; file1.php接收响应就好了，但是当我尝试保持file2.php运行时，file1.php永远不会收到响应，我做错了什么？我必须以不同的方式将响应发送回file1.php吗？

// file1.php
    $url = "file2.php"

    $params = array('compurl'=>$compurl,'validatecode'=>$validatecode);

    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => true,     // return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "Mozilla", // who am i
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
        CURLOPT_TIMEOUT        => 10,       // don't wait too long
        CURLOPT_POST           => true,     // Use Method POST (not GET)
        CURLOPT_POSTFIELDS     => http_build_query($params)
    );
    $ch = curl_init($url);

    curl_setopt_array( $ch, $options );
    $response = curl_exec($ch); 
    curl_close($ch);
    echo $response;

// file2.php
ob_start();
echo 'Running in the background.';

// get the size of the output
$size = ob_get_length();

header("HTTP/1.1 200 OK"); // I have tried without this
header("Date: " . date('D, j M Y G:i:s e')); // Tried without this
header("Server: Apache"); // Tried without this
header('Connection: close');
header('Content-Encoding: none');
header("Content-Length: $size");
header("Content-Type: text/html"); // Tried without this

// flush all output
ob_end_flush();
ob_flush();
flush();

// If I add return; here file1.php gets the response just fine
// But I need file2.php to keep processing stuff and if I remove the
// return; file1.php never gets a response.

在正常的卷曲转移中，在页面完成加载之前，您将无法获取数据，即。你的脚本完成了。如果要使用部分数据，则应查看CURLOPT_WRITEFUNCTION。这会创建一个回调，只要有任何数据，您就可以使用它。

PHP Curl输出缓冲区没有收到响应
