Question

这是我的PHP代码：

$source = $_POST['source'];
$destination = $_POST['destination'];
$class = $_POST['class'];
$day = $_POST['day'];
$month = $_POST['month'];

$data = array(
    'lccp_src_stncode_dis' => $source,
    'lccp_dstn_stncode' => $destination,
    'lccp_classopt' => $class,
    'lccp_day' => $day,
    'lccp_month' => $month
);

# Create a connection
$url = 'data as per raw req ';
$ch = curl_init($url);

echo $ch." <br>";

# Form data string
$postString = http_build_query($data);

echo $postString;
$header = array (   
            'Host' => 'data as per raw req '
            'Connection'=> 'keep-alive',
            'Content-Length'=> '180',
            'Cache-Control'=> 'max-age=0',
            'Accept'=> 'text/html',
            'Origin'=> 'data as per raw req ',
            'User-Agent' => '',
            'Content-Type' => 'application/x-www-form-urlencoded',
            'Referer': 'data as per raw req '
            'Accept-Encoding'=> '',
            'Accept-Language' => 'en-US,en;q=0.8'

    );

# Setting options
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postString);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
//# Get the response
curl_setopt($ch, CURLOPT_POSTFIELDS, 
$response = curl_exec($ch);
curl_close($ch);

#print response
echo "
$response
";

从以下地址接收表格数据：

<html>
    <form method="post" action="poster.php">
        <table>
            <tr><td>source:</td><td><input type="text" name="source"></td></tr>
            <tr><td>destination:</td><td><input type="text" name="destination"></td></tr>
            <tr><td>day:</td><td><input type="text" name="day"></td></tr>
            <tr><td>month:</td><td><input type="text" name="month"></td></tr>
            <tr><td>class:</td><td><input type="text" name="class"></td></tr>
            <tr><td><input type="submit" name="submit" value="Submit"></td>
            <td><input type="reset" name="reset" value="Reset"></td></tr>
        </table>
</form>
</html>

这是原始请求

Host: www.indianrail.gov.in

Content-Length: 91

lccp_src_stncode_dis=ndls&lccp_dstn_stncode=HYB&lccp_classopt=SL&lccp_day=26&lccp_month=6

Fiddler正在给出来自cgi的相应响应，而php脚本只是显示了html容器，我已经被困了一个多小时！请帮忙！

^关闭话题：这次为什么只让我发布链接，应该被认为是链接？

另外，我会比较fiddler中的会话，但是fiddler会在本地主机上向我自己的应用程序显示请求，而不是从我的应用程序到印度铁路网站。截图： NEVERMIND，没有足够的回复
编辑：如果有人能告诉我如何使用http_request2发出这个请求，我会很高兴。我已经发布了确切的原始请求，在评论中给我提供了fiddler所需的输出，所以不，我不是缺少任何身份验证和Cookie标头等

标题不能作为关联数组输入，这是错误的：

$header = array (   
            'Host' => 'data as per raw req '
            'Connection'=> 'keep-alive',
            'Content-Length'=> '180',
            'Cache-Control'=> 'max-age=0',
            'Accept'=> 'text/html',
            'Origin'=> 'data as per raw req ',
            'User-Agent' => '',
            'Content-Type' => 'application/x-www-form-urlencoded',
            'Referer': 'data as per raw req '
            'Accept-Encoding'=> '',
            'Accept-Language' => 'en-US,en;q=0.8'
             );

正确的方法：

$header = array (   
            'Host:*data as per raw req* '
            'Connection:keep-alive',
            'Content-Length:180',
            'Cache-Control:max-age=0',
            'Accept:text/html',
            'Origin:*data as per raw req* ',
            'User-Agent:',
            'Content-Type:application/x-www-form-urlencoded',
            'Referer:*data as per raw req* '
            'Accept-Encoding:',
            'Accept-Language:en-US,en;q=0.8'
             );

即使在我使用的关联数组中输入的数据也被格式化为url编码的post字符串，显然所有内容都必须输入，因为它在原始http请求中。 cURL并没有真正做任何格式化。

php curl与fiddler没有得到相同的回应
