CURL POST显示为put

Question

I am trying to post a request to Amazon MWS Feeds API, and I am using the following php:

    private function submit_feed_request($xml)
{
    $feed_handle = @fopen('php://temp', 'rw+');
    fwrite($feed_handle, $xml);
    rewind($feed_handle);
    $md5 = base64_encode(md5(stream_get_contents($feed_handle, true)));
    $options_string = '';
    $count = 0;
    foreach ($this->options as $k => $v)
    {
        $options_string .= rawurlencode($k) . "=" . rawurlencode($v);
        $options_string .= ($count == count($this->options) -1)? '': "&";
        $count++;
    }
    $this->options['PurgeAndReplace'] = false;
    $this->options['Version'] = '2009-01-01';

    $curl_options = array(
            CURLOPT_CAINFO=>$_SERVER['DOCUMENT_ROOT'] . "\public\amazon_api\cacert_pem.crt",
            CURLOPT_RETURNTRANSFER=>true,
            CURLOPT_POST=>1,
            CURLOPT_PORT=>443,
            CURLOPT_POSTFIELDS=> $options_string,
            CURLOPT_SSL_VERIFYHOST=>2,
            CURLOPT_SSL_VERIFYPEER=> TRUE,
            CURLOPT_FOLLOWLOCATION => 1,
            CURLOPT_PROTOCOLS=> CURLPROTO_HTTPS,
            CURLINFO_HEADER_OUT =>true,
            CURLOPT_HTTPHEADER=> array('Content-Type: text/xml','User-Agent: ADS EV 1.0', 'Transfer-Encoding: chunked', 'Host: mws.amazonservices.com', 'Content-MD5: ' . $md5),        
            CURLOPT_INFILE => $feed_handle,
            CURLOPT_UPLOAD=>true,
            //CURLOPT_CUSTOMREQUEST =>'POST_UPLOAD',
            CURLOPT_VERBOSE => true,
            CURLOPT_HEADER =>true,
    );
    $session = curl_init($this->url);
    curl_setopt_array($session, $curl_options);
    $results = curl_exec($session);
    $errors = curl_error($session);
    $info = curl_getinfo($session);
    curl_close($session);
    var_dump($results);
    echo "<br /><br />";
    print_r($info); 
}       

This outputs the following:

Why does my request Header show as a Put request when I am setting the POST option?

Answer 1

When you use the CURLOPT_INFILE option, the method is automatically changed to PUT. I didn't realize that the API I was using requires you to override this operation with CURLOPT_CUSTOMREQUEST = "POST"
