Homephp教程php手册php 获取qq用户昵称和在线状态实例

如果我们利用php获取QQ用户名与在线状态QQ并未给我们提供api接口了,如果要获取我们可以通过QQ空间或QQ网页版聊天来实现。

QQ通过返回不同的图片,来表示在线或离线,图标也随之变换

既然图片不同,那么,返回的HTTP头信息中的Content-Length 也一定不同,而且,彩色图片一定会比同样子的暗色图片要大,于是,找出某个样式的彩色与暗色图片的中间值,就能达到通过判断头部返回长度的方法来获取QQ在线状态

以下是代码

<?php
function get_qq_status($uin) {
    error_reporting(0);
    $f = file_get_contents(&#39;http://wpa.qq.com/pa?p=1:&#39; . $uin . &#39;:4&#39;);
    if (!$f) return (true);
    foreach ($http_response_header as $val) {
        if (strpos($val, &#39;Content-Length&#39;) !== false) {
            return (intval(substr($val, 16, 50)) > 1000);
        }
    }
}
?>

上面比较简单,下面来个更好的

<?php
function tphp_qq_online($uin) {
    $reques = "GET /pa?p=1:" . $uin . ":1 HTTP/1.1rn";
    $reques.= "Host: wpa.qq.comrn";
    $reques.= "User-Agent: PHP_QQ_SPYrnrn";
    if (!($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP))) return (-1);
    if (!(socket_connect($socket, "wpa.qq.com", 80))) return (-1);
    if (!(socket_write($socket, $reques))) return (-1);
    if (!($respon = socket_read($socket, 1024, PHP_BINARY_READ))) return (-1);;
    socket_close($socket);
    $field = explode("rn", $respon);
    for ($i = 0; $i < count($field); $i++) {
        if (strncasecmp($field[$i], "Location:", 9) == 0) {
            if (strpos($field[$i], "online")) {
                $ret = 1;
            } else if (strpos($field[$i], "offline")) {
                $ret = 0;
            } else {
                $ret = - 1;
            } // if
            break;
        } // if
        
    } // for
    return ($ret);
}
/* }}} */
echo tphp_qq_online(561272831);
?>

例,qq用户昵称和在线状态

<?php
//获取QQ状态
function getQQState($qq) {
    $url = &#39;http://wpa.qq.com/pa?p=2:&#39; . $qq . &#39;:41&r=&#39; . time();
    $headInfo = get_headers($url, 1);
    $length = $headInfo[&#39;Content-Length&#39;];
    if ($length == 1243) {
        return true;
    } else {
        return false;
    }
}
//获取QQ昵称
function getQQNick($qq) {
    $str = file_get_contents(&#39;http://r.qzone.qq.com/cgi-bin/user/cgi_personal_card?uin=&#39; . $qq);
    $pattern = &#39;/&#39; . preg_quote(&#39;"nickname":"&#39;, &#39;/&#39;) . &#39;(.*?)&#39; . preg_quote(&#39;",&#39;, &#39;/&#39;) . &#39;/i&#39;;
    preg_match($pattern, $str, $result);
    return $result[1];
}
//获取QQ姓名
function getQQName($qq) {
    //$qqArr = include &#39;friendArr.php&#39;;//预先设置的
    //$username = $qqArr[$qq];
    if (!$username) {
        $username = getQQNick($qq);
    }
    return $username;
}
?>
