Question

I have a hosted server with curl installed, but not http_post_data() pecl.

I’m trying to translate this (working) http_post_data() code to curl:

$responseString = @http_post_data("http://" . $this->username . ":" . $this->password ."@" . $this->webserviceHost . $this->requestUriBase .$request,
    $requestString,
    array('http_auth' => $this->username . ":" . $this->password, 'headers' => array('Content-Type' => 'text/xml')));

I’ve tried:

$url = "http://" . $this->username . ":" . $this->password ."@" . $this->webserviceHost . $this->requestUriBase .$request;
        curl_setopt($this->curl, CURLOPT_HTTPHEADER, array('Accept: application/xml', 'Content-Type: application/xml'));
        curl_setopt($this->curl, CURLOPT_URL, $url);
        curl_setopt($this->curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
        curl_setopt(CURLOPT_USERPWD, "[$this->username]:[$this->password]");
        curl_setopt ($this->curl, CURLOPT_POST, true);
        curl_setopt ($this->curl, CURLOPT_POSTFIELDS, array($requestString));
        $content = curl_exec($this->curl);  

… and failed: couldn’t connect to host

What’s the correct code?

Answer 1

To configure and execute a CURL request, I suggest the following format:

    # in curl URL is scheme://hostname/rest, and hostname != authority
    #     (authority is hostname plus port and with user/pass in front)

    $url = sprintf('http://%s/%s', $this->webserviceHost
                    , $this->requestUriBase . $request);
    $options = array(
         CURLOPT_HTTPHEADER     => array(
             'Accept: application/xml', 
             'Content-Type: application/xml',
         ),
         CURLOPT_HTTPAUTH       => CURLAUTH_BASIC,
         # don't use the brackets []
         CURLOPT_USERPWD        => $this->username . ':' . $this->password,
         CURLOPT_POST           => TRUE,
         CURLOPT_POSTFIELDS     => $requestString,
         CURLOPT_RETURNTRANSFER => TRUE,
    );

    $this->curl = curl_init($url);
    $r = curl_ setopt_ array($this->curl, $options);
    if (!$r) throw new Exception('Failed to setup options.');
    $content = curl_exec($this->curl); # This needs CURLOPT_RETURNTRANSFER => TRUE

I’m not sure about CURLOPT_POSTFIELDS because you don’t have specified what $requestString contains. It’s likely that this setting above is wrong. See curl POST format for CURLOPT_POSTFIELDS.

Edit: You have specified it via http_post_data:

String containing the pre-encoded post data

Curl supports that as well, just don’t pass as array, pass it as string:

     CURLOPT_POSTFIELDS     => $requestString,
