curl json不保存cookiefile PHP

Question

当我在任何主机中使用带有 json 的 curl 登录时，我无法保存 cookiefile。这是我的代码：

<?php
function curl($url = false, $var = false, $cookie = false, $header = false)
{
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_URL, $url);
        if($var){
		curl_setopt($ch, CURLOPT_POSTFIELDS,$var);
        }
        curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0');
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
		curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
		curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie); 
		curl_setopt($ch, CURLOPT_REFERER, $header);
		@curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);		
		curl_setopt($ch, CURLOPT_HTTPHEADER, array(
			'Content-Type: application/json',
            'charset=utf-8',
			'Content-Length: ' . strlen($var)
        )); 
		$error = curl_error($ch);
		$result = curl_exec($ch);
		curl_close ($ch);
		return $result;
        return $error;
}
    $urlcheck = 'http://abcxyz.com/api/login';
    $username = 'xxxxxxxx';
    $password = 'xxx';
    $passmd5 = @md5($password);
	$request = '{"username":"'.$username.'","password":"'.$password.'","passwordMD5":"'.$passmd5.'"}';
	$data = json_decode($request);
	if (empty($data->username) || empty($data->password)){
		echo " Thieu du lieu";
	}else{
		$ck = str_replace('\\','/',dirname(__FILE__)).'/cookies/'.$data->username.'.txt';	
        $curl = curl($urlcheck,$request,$ck);
        echo $curl;	
		}
?>

我有 chmod 0777 目录 /cookies/。

Answer 1

设置 CURLOPT_COOKIEJAR 时，需要使用绝对路径。您可以使用

轻松做到这一点

curl_setopt ($ch, CURLOPT_COOKIEJAR, realpath($cookie_file) );

Answer 2

http://curl.haxx.se/libcurl/c/CURLOPT_COOKIEJAR.html

请注意，libcurl 不会从 cookie jar 中读取任何 cookie。如果你 要从文件中读取 cookie，请使用 CURLOPT_COOKIEFILE。

如果您的请求应该是 POST 请求，则您没有指示 curl 发送 POST 请求。以下与您的函数略有不同，因为该函数没有 $cookie 参数 - curl 请求将使用系统临时目录来存储 cookie。

<?php
    function curl( $url = false, $var = false, $header = false ){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);

        if( $var ){
            /* send POST request */
            curl_setopt($ch, CURLOPT_POST,true);
            curl_setopt($ch, CURLOPT_POSTFIELDS,$var);
        }
        /* Use the systems temp dir to store cookies */
        $cookiejar=tempnam( sys_get_temp_dir(), 'cookiejar_' );
        $headers=array('Content-Type: application/json','charset=utf-8');
        if( $var ) $headers[]='Content-Length: ' . strlen($var);

        curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0');
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true ); 
        curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiejar );
        curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiejar ); 
        curl_setopt($ch, CURLOPT_REFERER, $header );
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);     
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers ); 

        $error = curl_error($ch);
        $result = curl_exec($ch);
        curl_close($ch);
        /* you can't expect two return statements to both return data ! */
        return $result;
    }

    $urlcheck = 'http://abcxyz.com/api/login';
    $username = 'xxxxxxxx';
    $password = 'xxx';
    $passmd5 = md5($password);
    $request = '{"username":"'.$username.'","password":"'.$password.'","passwordMD5":"'.$passmd5.'"}';
    $data = json_decode($request);

    if ( empty($data->username) || empty($data->password) ){
        echo " Thieu du lieu";
    }else{
        $curl = curl( $urlcheck, $request );
        echo $curl; 
    }
?>
