显示 Curl POST 请求标头？ 有没有办法做到这一点？

Question

I'm building a Curl web automation app and am having some issue with not getting the desired outcome of my POST action, I am having some trouble figuring out how I can show the full POST request I am sending over (with headers), I have been searching on this but everything that comes up is the response headers, actually I want these too but also the request, which none of the posts I find on google seem to mention..

I know I can display the result of a curl request using something like this (forgive me if my syntax is off, I already shut down my virtual machine with my ide and code to refer to

 $result = curl($curl_exect) ;

Anyways, I would greatly appreciate any advice on how to view the full headers, thanks

Answer 1

Here is all you need:

curl_setopt($curlHandle, CURLINFO_HEADER_OUT, true); // enable tracking
... // do curl request    
$headerSent = curl_getinfo($curlHandle, CURLINFO_HEADER_OUT ); // request headers

Answer 2

You can see the information regarding the transfer by doing:

curl_setopt($curl_exect, CURLINFO_HEADER_OUT, true);

before the request, and

$information = curl_getinfo($curl_exect);

after the request

View: http://www.php.net/manual/en/function.curl-getinfo.php

You can also use the CURLOPT_HEADER in your curl_setopt

curl_setopt($curl_exect, CURLOPT_HEADER, true);

$httpcode = curl_getinfo($c, CURLINFO_HTTP_CODE);

return $httpcode == 200;

These are just some methods of using the headers.

Answer 3

You can save all headers sent by curl to a file using :

$f = fopen('request.txt', 'w');
curl_setopt($ch,CURLOPT_VERBOSE,true);
curl_setopt($ch,CURLOPT_STDERR ,$f);

Answer 4

You can make you request headers by yourself using:

// open a socket connection on port 80
$fp = fsockopen($host, 80);

// send the request headers:
fputs($fp, "POST $path HTTP/1.1\r\n");
fputs($fp, "Host: $host\r\n");
fputs($fp, "Referer: $referer\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ". strlen($data) ."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $data);

$result = ''; 
while(!feof($fp)) {
    // receive the results of the request
    $result .= fgets($fp, 128);
}

// close the socket connection:
fclose($fp);

I had exactly the same problem lately, and I installed Wireshark (it is a network monitoring tool). You can see everything with this, except encrypted traffic (HTTPS).
