我在使用freebase MQL登录服务时遇到问题。我做了一个post请求,然后freebase api应该发回头文件,然后我将分析并从中获取信息。

但我唯一得到的头球是 HTTP/1.0 200 OK

代码

class myFreebaseClass {

....

function doLogin() {

echo $uri = "http://".$this->config['apiSandboxHost'].'/'.$this->config['apiLoginPath'].'username='.$this->config['apiLoginUser'].'&password='.$this->config['apiLoginPass'];

$ch = curl_init($uri);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADERFUNCTION, array(&$this,'readHeader'));
$output = curl_exec($ch);
curl_close($ch);

}

function readHeader($ch, $string)
{
    echo "Header: ".$string."<Br />";
    if(strpos($string, 'Set-Cookie') !== false) {
        $this->authCookies[] = str_replace('Set-Cookie: ', '', $string);
    }
    return true;
}

}

输出

http://sandbox.freebase.com/api/account/login?username=dXXXXX&password=XXXX
Header: HTTP/1.0 200 OK

我做错什么了?我得到的标题不正确吗?

这最终成为了一个问题 readHeader() 功能。在我的例子中,我回来了 true . 当我返回每个标题的长度时,一切都正常了。例如

function readHeader($ch, $string)
{
    $length = strlen($string);
    if(strpos($string, 'Set-Cookie') !== false) {
        $this->authCookies[] = str_replace('Set-Cookie: ', '', $string);
    }
    return $length;
}

希望这能帮助别人!

这似乎是PHP的curl的一个bug,我在下面几行中也遇到了同样的问题:

function readHeader($ch, $string)
{
    echo "Header: ".$string."<Br />";
}

echo $uri = 'http://localhost/';

$ch = curl_init($uri);
curl_setopt($ch, CURLOPT_HEADER, 1);//this line can also be omitted
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'readHeader');
$output = curl_exec($ch);
curl_close($ch);

你必须用传统的方法提取邮件头:

class myFreebaseClass {

....

function doLogin() {

    echo $uri = "http://".$this->config['apiSandboxHost'].'/'.$this->config['apiLoginPath'].'username='.$this->config['apiLoginUser'].'&password='.$this->config['apiLoginPass'];

    $ch = curl_init($uri);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADERFUNCTION, array(&$this,'readHeader'));
    $output = curl_exec($ch);

    //extracting headers:
    $infos = curl_getinfo($ch);
    $headers = substr($output, 0, $infos['header_size']);
    $headers = explode("\n", $headers);
    //done extracting headers
    $output = substr($output, $infos['header_size']);

    foreach($headers as $header) {
        readHeader($ch, trim($header));
    }
    curl_close($ch);

    }

    function readHeader($ch, $string)
    {
        echo "Header: ".$string."<Br />";
        if(strpos($string, 'Set-Cookie') !== false) {
            $this->authCookies[] = str_replace('Set-Cookie: ', '', $string);
        }
        return true;
    }

}
