Question

功能：

function post_with_curl($target,$ref, $name ,$viewStateValue )
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $target) ;       // Target site

        curl_setopt($ch, CURLOPT_COOKIEFILE, str_replace('\\','/', getcwd().'/'."cook.txt" )); //CHANGE THIS 
        curl_setopt($ch, CURLOPT_REFERER, $ref);  
        curl_setopt($ch, CURLOPT_TIMEOUT, CURL_TIMEOUT);    // Timeout
        curl_setopt($ch, CURLOPT_USERAGENT, WEBBOT_NAME); 
        curl_setopt ($ch, CURLOPT_POST, 1);


        $postfields = urlencode('__EVENTTARGET=&__EVENTARGUMENT=&__VIEWSTATE=.'. $viewStateValue. '&__VIEWSTATEENCRYPTED=&ctl00$ContentPlaceHolder1$NameSearch1$CompanyNameTextBox1='.$name.'&ctl00$ContentPlaceHolder1$SearchButton=Search Now' ) ;
        curl_setopt ($ch, CURLOPT_POSTFIELDS, $postfields );

        curl_setopt($ch, CURLOPT_HEADER, 1);
        curl_setopt($ch, CURLINFO_HEADER_OUT, true);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);     // Follow redirects
        curl_setopt($ch, CURLOPT_MAXREDIRS, 4);             // Limit redirections to four
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);     // Return in string  
        $curled_page = curl_exec($ch);
        var_dump(curl_getinfo($ch , CURLINFO_HEADER_OUT)) ;
        curl_close($ch);
        return $curled_page ;
    }

var_dump的结果（curl_getinfo（$ ch，CURLINFO_HEADER_OUT））：

在我看来，标题（由curl发送？）不包含任何POST数据。为什么？

Answer 1

这是因为post数据不是HTTP消息头部的一部分，而是HTTP消息体的一部分。如果你得到标题，你就不会得到身体。如果要检索正文，则必须检索邮件正文。

顺便说一句，您不需要检索它，因为您已经将它自己创建到$postfields变量中。这只是发布的数据。

或者我误读了你实际要求的东西？

curl发送的标头不包含POST数据
