Question

I’m making simple http post request using libcurl to index.php file on my web server
that has the following simple code writing post data to a file

if (isset($_POST['abc'])){
    $log="abc.log";
    $h=fopen($log,"w");
    fwrite($h,$_POST['abc']);
    fclose($h);
}  

while my written c++ code implementing http post request is the following

    CURL *curl;
    CURLcode res;
    curl=curl_easy_init();
    string url=AnsiString("http://127.0.0.1/curl/index.php?abc=123").c_str();
    string data="abc=3434";
    if (curl) {

        curl_easy_setopt(curl, CURLOPT_POST, 1);
        curl_easy_setopt(curl, CURLOPT_POSTFIELDS,AnsiString("abc=3434").c_str());
        curl_easy_setopt(curl, CURLOPT_URL,AnsiString("http://127.0.0.1/curl/index.php").c_str());
        res=curl_easy_perform(curl);
        curl_easy_cleanup(curl);
    }

First, posting is enabled curl_easy_setopt(curl, CURLOPT_POST, 1);

Second, if I debug this code i get CURL_OK status in res (return value)
and also TCP 127.0.1:80 will be established everytime i run the code monitoring via netstat -ano 15 but the file abc.log is empty

What’s wrong with this??
Haven’t you any idea pointing me to the right way?

Thank you
in advance!

Sending CURLOPT_POSTFIELDSIZE helped!
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE,data.Length());

Apache log says it’s ok you’ve sent POST

127.0.0.1 - - [03/Mar/2012:17:39:06 +0500] "POST /curl/post.php HTTP/1.1" 200 -
