Question

我想将帖子数据发送到页面以获取价值。问题是我想从abc.com获取数据。只有当用户从abc.com abc.com来到abc.com/previous url时才会打开url has be moved。

也许正在做一些会话或cookie来进行身份验证。我不知道。

我想要做的是从abc.com获取数据。有没有办法通过卷曲来做到这一点？

我的PHP代码：

当您运行代码$SearchBy = "2"; $AttorneySearchMode="Name"; $LastName= "Smith"; $FirstName= "William"; $CaseStatusType= "0"; $SortBy= "fileddate"; echo $url = 'https://www.clarkcountycourts.us/Anonymous/Search.aspx?ID=400&NodeID=101%2c103%2c104%2c105%2c500%2c600%2c601%2c602%2c603%2c604%2c605%2c606%2c607%2c608%2c609%2c610%2c611%2c612%2c613%2c614%2c615%2c616%2c617%2c618%2c619%2c699%2c700%2c701%2c702%2c703%2c704%2c705%2c706%2c707%2c708%2c709%2c710%2c711%2c712%2c713%2c714%2c715%2c716%2c717%2c718%2c719%2c720%2c721%2c722%2c723%2c724%2c725%2c726%2c727%2c728%2c729%2c730%2c731%2c797%2c798&NodeDesc=All+Courts'; //set POST variables $fields = array( 'SearchBy' => urlencode($SearchBy), 'AttorneySearchMode' => urlencode($AttorneySearchMode), 'LastName' => urlencode($LastName), 'FirstName' => urlencode($FirstName), 'CaseStatusType' => urlencode($CaseStatusType), 'SortBy' => urlencode($SortBy), ); $fields_string = ""; foreach ($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; } rtrim($fields_string, '&'); $ch = curl_init(); curl_setopt($ch,CURLOPT_URL, $url); curl_setopt($ch,CURLOPT_POST, true); curl_setopt($ch,CURLOPT_POST, count($fields)); curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string); $result = curl_exec($ch); curl_close($ch); print_r($result);时，对于此网址，您需要来自旧的引用网址，然后才能在浏览器中使用

<div>
<table>
    <thead>
        <!-- Example with only 2 columns -->
        <tr>
            <th>Col1</th>
            <th>Col2</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>foo</td>
            <td>this</td>
        </tr>
        <tr>
            <td>bar</td>
            <td>that</td>
        </tr>
    </tbody>

Answer 1

这是一个有一些小修改的起点。

我发现3个问题阻止我在他们的服务器上请求页面：

需要在cURL中启用Cookie并在发布
需要禁用SSL检查（CURLOPT_SSL_VERIFYPEER，CURLOPT_SSL_VERIFYHOST）
请求中缺少一些必要的表单字段

在下面的示例中，我首先获取主搜索页面，然后重新使用相同的cURL句柄发布表单。请注意，这是不完整的，您需要编写代码来填充剩余的表单字段。

// first fetch search page to set cookies
$url = 'https://www.clarkcountycourts.us/Anonymous/Search.aspx?ID=400&NodeID=101%2c103%2c104%2c105%2c500%2c600%2c601%2c602%2c603%2c604%2c605%2c606%2c607%2c608%2c609%2c610%2c611%2c612%2c613%2c614%2c615%2c616%2c617%2c618%2c619%2c699%2c700%2c701%2c702%2c703%2c704%2c705%2c706%2c707%2c708%2c709%2c710%2c711%2c712%2c713%2c714%2c715%2c716%2c717%2c718%2c719%2c720%2c721%2c722%2c723%2c724%2c725%2c726%2c727%2c728%2c729%2c730%2c731%2c797%2c798&NodeDesc=All+Courts';

$ch = curl_init();

// needed to disable SSL checks for this site
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);

// enable cookie handling (they aren't saved after cURL is closed)
curl_setopt($ch,CURLOPT_COOKIEFILE, '');

// debugging
curl_setopt($ch,CURLOPT_VERBOSE, 1);
curl_setopt($ch,CURLOPT_STDERR, fopen('php://output', 'w'));

// helpful options
curl_setopt($ch,CURLOPT_AUTOREFERER, true);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);

// set first URL
curl_setopt($ch,CURLOPT_URL, $url);

// execute first request to establish cookies & referer    
$data = curl_exec($ch);

// TODO: extract hidden form fields/values from form 
$fields_string = '...';

// now make second request
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

$result = curl_exec($ch);
curl_close($ch);
var_dump($result);
