PHP cURL 请求更改 POST 数据

Question

我使用 PHP cURL 模块的 POST 请求有问题。我有一个这样的字符串$new_post（因为它太长了，所以在这里剪掉了）：

    $new_post = '...AvailabilitySearchInputScheduleSelectView$RadioButtonMarketStructure='.$tipe.'&AvailabilitySearchInputScheduleSelectView$DropDownListMarketDay1='.$tanggal1.'&AvailabilitySearchInputScheduleSelectView$DropDownListMarketMonth1='.$bulan1.'&date_picker='.$bulan1.'-'.$tanggal1.'&AvailabilitySearchInputScheduleSelectView$DropDownListMarketDay2='.$tanggal2.'&AvailabilitySearchInputScheduleSelectView$DropDownListMarketMonth2='.$bulan2.'&date_picker='.$bulan2.'-'.$tanggal2.'&...;

当我使用curl_exec 发布该内容时，POST 字符串会自行更改。子字符串 AvailabilitySearchInputScheduleSelectView 更改为 AvailabilitySearchInputSearchView。我用 Firebug 查了一下。

我不知道为什么会这样。谁能告诉我为什么会这样？这是我的请求代码：

    $data = curl_init();
    curl_setopt($data, CURLOPT_CONNECTTIMEOUT, 180);
    curl_setopt($data, CURLOPT_URL, $url);
    curl_setopt($data, CURLOPT_FAILONERROR,1);
    curl_setopt($data, CURLOPT_FOLLOWLOCATION,1);
    curl_setopt($data, CURLOPT_VERBOSE, 1);
    curl_setopt($data, CURLOPT_POST, true);
    curl_setopt($data, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($data, CURLOPT_POSTFIELDS, $new_post);
    curl_setopt($data, CURLOPT_FAILONERROR,0);
    curl_setopt($data, CURLINFO_HEADER_OUT, true);
    curl_setopt($data, CURLOPT_COOKIEJAR, $cookie);
    curl_setopt($data, CURLOPT_COOKIEFILE, $cookie);
    curl_setopt($data, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0");
    $result = curl_exec($data);

如果我在真实的网页中这样做，这正是正确的帖子。我试图以同样的方式发布。很抱歉我可以上传我的萤火虫的截图，因为我没有足够的声誉。

Answer 1

您不会在 Firebug 中看到 cURL 请求，因为它发生在服务器上。

当我的 localhost 将 POST 数据发送到 URL (localhost/test2.php) 时，我看到了 AvailabilitySearchInputSearchView，我还使用 firebug 对其进行了检查。

如果您在 Firebug 中看到 AvailabilitySearchInputSearchView，但是当您在通过 curl_exec() 调用的 PHP 脚本中 echo 时获得正确的 POST 正文，则您的问题与 cURL 请求无关。

Answer 2

您可以在将http_build_query() 传递给curl_setopt() 之前使用它，如下所示：

$post = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'AvailabilitySearchInputScheduleSelectView$RadioButtonMarketStructure');

$post  = http_build_query($post);

$data = curl_init();
curl_setopt($data, CURLOPT_CONNECTTIMEOUT, 180);
curl_setopt($data, CURLOPT_URL, $url);
curl_setopt($data, CURLOPT_FAILONERROR,1);
curl_setopt($data, CURLOPT_FOLLOWLOCATION,1);
curl_setopt($data, CURLOPT_VERBOSE, 1);
curl_setopt($data, CURLOPT_POST, true);
curl_setopt($data, CURLOPT_RETURNTRANSFER, true);
curl_setopt($data, CURLOPT_POSTFIELDS, $post );
curl_setopt($data, CURLOPT_FAILONERROR,0);
curl_setopt($data, CURLINFO_HEADER_OUT, true);
curl_setopt($data, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($data, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($data, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0");
$result = curl_exec($data);
