Question

有没有解释为什么使用数组给我500内部服务器错误并且使用字符串只能在相同的输入下正常工作？

    $header_array[] = 'Host: example.com';
    $header_array[] = 'Accept-Language: tr-TR,tr;q=0.8,en-US;q=0.5,en;q=0.3';
 //   $header_array[] = 'Accept-Encoding: gzip, deflate';
    $header_array[] = 'Connection: keep-alive';
    $header_array[] = 'Cache-Control: no-cache';
    $header_array[] = 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8';
    $header_array[] = 'Pragma: no-cache';
    $header_array[] = 'Referer: https://example.com/post/'.$post_id;
    $header_array[] = 'X-Requested-With: XMLHttpRequest';
    $header_array[] = 'Content-Length: '.strlen("id=".$post_id);
    /* curl */
    curl_setopt( $ch, CURLOPT_HTTPHEADER, $header_array);
    curl_setopt( $ch, CURLOPT_POST, TRUE);

无法正常工作（内部服务器错误）：

    $post_array['id'] = "1";
    curl_setopt( $ch, CURLOPT_POSTFIELDS, $post_array);

工作：

    $post_string = "id=1";
    curl_setopt( $ch, CURLOPT_POSTFIELDS, $post_string);

这也适用于另一个网址：

    $post_array['__Token'] = $token;
    $post_array['UserName'] = $this->username;
    $post_array['Password'] = $this->password;
    curl_setopt( $ch, CURLOPT_POSTFIELDS, $post_array);

curl verbose错误输出：

如果您查看PHP手册，它会说：

将数组传递给CURLOPT_POSTFIELDS会将数据编码为 multipart / form-data，传递URL编码的字符串将进行编码数据为application / x-www-form-urlencoded。

你的代码中有这些行：

$header_array[] = 'Content-Length: '.strlen("id=".$post_id);
$header_array[] = 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8';

如果删除这些行，就可以了！

我的代码目前看起来像这样：

<?php 
    //$header_array[] = 'Host: example.com';

    //$header_array[] = 'Accept-Encoding: gzip, deflate';
    $header_array[] = 'Accept-Language: tr-TR,tr;q=0.8,en-US;q=0.5,en;q=0.3';
    $header_array[] = 'Connection: keep-alive';
    $header_array[] = 'Cache-Control: no-cache';

    $header_array[] = 'Pragma: no-cache';
    $header_array[] = 'Referer: https://example.com/post/'.$post_id;
    $header_array[] = 'X-Requested-With: XMLHttpRequest';
    //$header_array[] = 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8';
    //$header_array[] = 'Content-Length: '.strlen("id=".$post_id);
    /* curl */

    $ch = curl_init('http://example.com/your/file.php');

    curl_setopt( $ch, CURLOPT_HTTPHEADER, $header_array);
    curl_setopt( $ch, CURLOPT_POST, TRUE);
    $post_array['id'] = "1";
    curl_setopt( $ch, CURLOPT_POSTFIELDS, $post_array);


    $data = curl_exec($ch);
?>

如果显示相同的错误，请尝试添加：

$header_array[] = 'Transfer-Encoding: chunked';

为什么使用CURLOPT_POSTFIELDS的一个项目数组不起作用？
