PHP 将 cURL 返回 HTML 作为函数返回字符串，而不是输出到客户端 - PHP have cURL return HTML as function return string instead of outputing to client

PHP have cURL return HTML as function return string instead of outputing to client

在发出两个cURL请求后，第二个请求我想捕获返回的HTML并将其作为字符串传递回调用函数。现在，它将 HTML 输出到客户端。我搞砸了ob_end_clean()，ob_get_contents()没有成功。

这是我目前拥有的...

function stuff()
{
 //user/pass stuff omitted.
 $ch = curl_init();
 curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);
 curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);
 curl_setopt($ch,CURLOPT_HEADER,0);
 curl_setopt($ch,CURLOPT_URL,$url);
 curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);
 curl_setopt($ch,CURLOPT_COOKIEFILE,$cookies);
 curl_setopt($ch,CURLOPT_POSTFIELDS,"user=$cp_user&pass=$cp_pwd");
 curl_setopt($ch,CURLOPT_TIMEOUT,100020);
 ob_start();
 $f = curl_exec($ch);
 $h = curl_getinfo($ch);
 $p0 = explode('cpsess',$h['url']);
 $p1 = explode('/',$p0[1]);
 ob_end_clean();
 /***/
 ob_start();
 curl_setopt($ch,CURLOPT_URL,$q2a.$p1[0].$q2b);
 curl_setopt($ch,CURLOPT_HEADER, 0);
 curl_exec($ch);
 $r = ob_get_contents();
 ob_end_clean();
 /***/
 curl_close($ch);
 return $r;
}

使用

curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

然后捕获返回的内容

function stuff() {
    // function code before
    $r = curl_exec($ch);
    // function code after
    return $r;
}

不要为此使用任何ob_函数，因为如果CURLOPT_RETURNTRANSFER未显式设置为 true 1则 curl 不会返回或打印出请求中的任何内容。
