我正在尝试从Guru.com (http://www.guru.com/pro/search.aspx?#&&page=1&budget=1000-30000&cid=800&sort=PostedDateDescending). 如果您研究此链接，您会注意到它正在执行 ajax 请求以获取作业列表，并且只是在加载时填充虚拟 html。它是一个 ASP.NET 服务器，我试图模仿这个 ajax 请求来获取作业列表。这是我的代码

$file_contents = parent::fetchPage($url);
        $string = tidy_repair_string($file_contents);
        $xmldoc = new DOMDocument();
        $xmldoc->loadHTML($string);
        $xpathvar = new Domxpath($xmldoc);
        
        $titleResult = $xpathvar->query('//input[@name="__VIEWSTATE"]');
        $postvars = 'ctl00%24scriptMgr=ctl00%24scriptMgr%7Cctl00%24scriptMgr&__EVENTTARGET=ctl00%24scriptMgr&__EVENTARGUMENT=page%3D1%26budget%3D1000-30000%26cid%3D800%26sort%3DPostedDateDescending&ctl00_scriptMgr_HiddenField=&__LASTFOCUS=&ctl00%24procnt%24hdnSearchId=&ctl00%24procnt%24ddlBudgetMin=0&ctl00%24procnt%24ddlBudgetMax=0&ctl00%24procnt%24Location=rbworldwide&ctl00%24procnt%24ddlCountries=Select%20One&ctl00%24procnt%24ddlCities=Select%20One&ctl00%24procnt%24txtKeyWords=Keywords%20or%20Project%20ID&ctl00%24procnt%24hdnKeyWords=&ctl00%24procnt%24ucLeadResults%24hdnSrc=&ctl00%24procnt%24ucLeadResults%24hdnPageNo=&ctl00%24procnt%24ucLeadResults%24hdnSearchResults=&ctl00%24procnt%24ucLeadResults%24hdnProjectID=&ctl00%24procnt%24txtSearchName=&ctl00%24procnt%24txtSearchName_reqd=true&ctl00%24procnt%24hdnSelectedTab=0&ctl00%24procnt%24hdnSelectSvdSearch=&ctl00%24hdnGuid=GUID&__ASYNCPOST=true&';
        $postvars .= '__VIEWSTATE='.urlencode($titleResult->item(0)->attributes->getNamedItem('value')->textContent);
        parse_str($postvars, $query);
        
        print_r($query);
        
        $ch = curl_init("http://www.guru.com/pro/search.aspx");
        curl_setopt($ch, CURLOPT_POST      ,1);
        curl_setopt($ch, CURLOPT_POSTFIELDS    ,$query);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION  ,1); 
        curl_setopt($ch, CURLOPT_HEADER      ,1);  // DO NOT RETURN HTTP HEADERS

        curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
        curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: www.guru.com',

        echo $Rec_Data = curl_exec($ch);
        $Rec_Data = gzinflate(substr($Rec_Data, 10, -8));
        echo $Rec_Data;

我发送的标题与我在为 ajax 请求发送的 Live HTTP Headers firefox 插件上看到的相同。我收到以下响应标头。

而我在 guru.com 完成 ajax 时收到的 Live HTTP Headers 插件上看到的响应标头是

Guru.com 正在接收工作列表，而我正在接收不包含任何工作的虚拟 html。谁能告诉我我的代码有什么问题。以下是 Guru.com 发送到其服务器以进行 ajax 调用的请求标头。

您为每个请求发送不同的 ASP.Net 会话 cookie。

据推测，Guru.com 在返回数据之前会检查一个有效的、经过身份验证的会话。

您必须首先以编程方式登录网站并获取有效的会话 ID，然后在后续的 Ajax 请求中使用该 ID。
