Question

我创建了一个名为question_control.php的表单，其中包含5个字段，question，op1，op2，op3和op4。表单接受参数并将其发送到object.php，然后object.php将数据以类对象的形式写入文件。

    <form action="object.php" method="GET">

我尝试将数据发送到question_control.php，发现没有数据写入该文件。当我尝试向object.php发送数据时，我发现已经创建了新对象，但所有字段都是空的。我修改了curl_errno（）以查看是否发生了任何错误，但它返回0.这是代码

<?php

    $curl_connection = curl_init('http://127.0.0.1/project/object.php');

    curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);
    curl_setopt($curl_connection, CURLOPT_USERAGENT,"Mozilla/25.0 (compatible; MSIE 6.0; Windows NT 5.1)");
    curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);

    $post_data['question'] = 'My';
    $post_data['op1'] = '11';
    $post_data['op2'] = '22';
    $post_data['op3'] = '33';
    $post_data['op4'] = '44';

    foreach ( $post_data as $key => $value) 
    {
        $post_items[] = $key . '=' . $value;
    }
    $post_string = implode ('&', $post_items);

    print $post_string."\n";

    curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);

    $result = curl_exec($curl_connection);

    print $result;

    print_r(curl_getinfo($curl_connection));
    echo curl_errno($curl_connection)."\n";

    curl_close($curl_connection);

?>

Answer 1

正如问题评论中的讨论结果所示，您实际上必须提出GET请求，而不是POST请求。

所以试试这种方法：

<?php
$query_parameters = http_build_query([
    'question' => 'My',
    'op1' => '11',
    'op2' => '22',
    'op3' => '33',
    'op4' => '44'
]);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://127.0.0.1/project/object.php?' . $query_parameters);
// ... more curl_setopt(...) calls ...

因此，您可以通过查询分隔符?将查询参数附加到URL，并且 not 为请求指定任何POST字段。 GET是cURL的默认值，因此您无需再处理。

Answer 2

使用http_build_query函数生成urlencoded字符串以传入请求：

...
$post_data['question'] = 'My';
$post_data['op1'] = '11';
$post_data['op2'] = '22';
$post_data['op3'] = '33';
$post_data['op4'] = '44';
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, http_build_query($post_data, '', '&'));
...

我可能错过了使用静态值初始设置$post_data数组的要点，但是当您通过GET提交表单时，为什么不简单地使用表单中输入的值？

<?php
    $ch = curl_init( 'http://127.0.0.1/project/object.php' );
    curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, 30);
    curl_setopt( $ch, CURLOPT_USERAGENT,"Mozilla/25.0 (compatible; MSIE 6.0; Windows NT 5.1)");
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt( $ch, CURLOPT_POST, true );

    /* automatically generate the required post data using the $_GET array data sent by the form */
    curl_setopt( $ch, CURLOPT_POSTFIELDS, http_build_query( $_GET ) );

    $result = curl_exec( $ch );
    $info=curl_getinfo( $ch );
    $errors=curl_errno( $ch );
    curl_close( $ch );

    if( !empty( $result ) ) echo $result;
    if( !empty( $info ) ) print_r( $info );
    if( !empty( $errors ) ) print_r( $errors );
?>
