curl_close($campo_r ); 


$htm1_R= htmlentities($html_ini_r);

echo $htm1_R;

我在哪里错了？ Cookies是正确的，因为在其他网页上我可以下载数据，链接是正确的，我不知道我哪里写错了。所有变量都是正确的，我已经检查了值的准确性。

我通过从 $ postdata_ini_r 中删除参数来解决此问题：

$postdata_ini_r = 
array(
    '__VIEWSTATE' => $viewstate_ini_r,
    '__VIEWSTATEGENERATOR' => $viewstategenerator_ini_r,
    '__EVENTVALIDATION' => $eventvalidation_ini_r,
    'ctl00$ctl00$hwsid' => $hwsid_ini_r,
    'ctl00$ctl00$PageSessionId' => $pagesessionid_ini_r,
    'ctl00$ctl00$DefaultUrl' => $defaulturl_ini_r,
    'ctl00$ctl00$GenericErrorUrl' => $genericerrorurl_ini_r,
    'ctl00$ctl00$PopupElement' => '',
    'ctl00$ctl00$PollingTimeoutSecs' => $pollingtimeoutsecs_ini_r,
    'ctl00$ctl00$mainContent$titleContent$cldDataInizio$txtData' => $oggi,
    'ctl00$ctl00$mainContent$titleContent$cldDataFine$txtData' => '',
    'ctl00$ctl00$mainContent$titleContent$dropStatiRichiesta' => '-1', 
    'ctl00$ctl00$mainContent$titleContent$dropTipiRichiesta' => '-1', 
    'ctl00$ctl00$mainContent$titleContent$btnFiltro' => 'Filtra'    
);

谢谢大家！
