我正在尝试将值发布到表单以从 aspx 页面获取数据，但我无法获取数据
要打开的第一个网址:
$url="https://www.clarkcountycourts.us/Anonymous/default.aspx"(此处设置 cookie)我们要搜索数据的第二个 url
$url3 ="https://www.clarkcountycourts.us/Anonymous/Search.aspx"
当我发布数据时，我只得到第 3 页的 html 而不是第 2 页的数据
下面是我的代码，我错过了什么？请指导我。
<?php
$url="https://www.clarkcountycourts.us/Anonymous/default.aspx";
$cookie="cookie.txt";
$url3 ="https://www.clarkcountycourts.us/Anonymous/Search.aspx";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie); // <-- add this line
curl_setopt ($ch, CURLOPT_REFERER, $url);
$result = curl_exec ($ch);
$SearchBy = "2";
$AttorneySearchMode="Name";
$LastName= "Smith";
$FirstName= "William";
$MiddleName ="";
$CaseStatusType= "0";
$SortBy= "fileddate";
$DateFiledOnAfter = "";
$DateFiledOnBefore = "";
$SearchSubmit ="Search";
$fields = array(

);
$fields_string = "";
foreach ($fields as $key=>$value) {
$fields_string .= $key.'='.$value.'&';
}
$fields_string = rtrim($fields_string, '&');
curl_setopt($ch, CURLOPT_URL, $url3);
curl_setopt($ch, CURLOPT_HEADER, true );
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
$result2 = curl_exec ($ch);
print_r($result2);
最佳答案
花了一些时间来弄清楚这一点 - 但下面的代码应该会在搜索后根据您对 William Smith 作为律师的原始查询回显结果。希望这是有道理的....

为完整起见，上面提到的实用程序类。
