Problem with curl to send Content-length header

问题:

i need to upload files to wupload here is my function

public function doPost($link, $postfields = '', $cookie = '', $ref = '', $nobody = false, $upload = false, $header = true, $headers = "") {
    $ch = curl_init($link);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    if ($header)
        curl_setopt($ch, CURLOPT_HEADER, 1);
    if ($headers)
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
    curl_setopt($ch, CURLOPT_REFERER, $ref);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1');
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
    curl_setopt($ch, CURLOPT_UNRESTRICTED_AUTH, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_VERBOSE, TRUE);  
    if ($postfields) {
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
    }
    if ($cookie) {
        curl_setopt($ch, CURLOPT_COOKIE, $cookie);
        curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
        curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);

    }
    $log = fopen("log.txt", "w+");
    curl_setopt($ch, CURLOPT_STDERR, $log);
    if ($upload) 
        curl_setopt($ch, CURLOPT_UPLOAD, true); 
    $page = curl_exec($ch);
    curl_close($ch);
    fclose($log);
    return($page);
}

and i tried to make this call

    $result = doPost("http://www.wupload.com/file-manager/list", '', $this->upcookies, "http://www.wupload.com/", false);
    preg_match("/_uploadServerHostname = '(s[0-9]*.wupload.com)'/i", $result, $matches);
    $server = $matches[1];
    $post = array();
    $post['files[]'] = "@$filelocation";
    $headers = array('Content-Type: application/octet-stream','Content-length: ' . filesize($filelocation));
    $page = $this->doPost($server, $post, $this->upcookies, "http://www.wupload.com", false, true, true, $headers);

and the result is

HTTP/1.1 411 Length Required Server: nginx Date: Sun, 21 Aug 2011 16:10:51 GMT Content-Type: text/html Content-Length: 174 Connection: close

i thought i sent the content lenght, cookies and file are ok. to be more clear, here is the curl log for this call

回答1:

When you upload with PUT (which CURLOPT_UPLOAD implies) you should set the size of the file to be uploaded with CURLOPT_INFILESIZE. (Or possibly the one made to support really large files: CURLOPT_INFILESIZE_LARGE).

回答2:

i removed that from the function and now it works

curl_setopt($ch, CURLOPT_UPLOAD, true);
