有没有办法注销在php中完成的摘要认证.

我试过unset($ _ SERVER ["PHP_AUTH_DIGEST"]); 但它不会要求重新登录.我知道如果我关闭浏览器然后它将工作,这是我的功能.

    function login(){
        $realm = "Restricted area";
        $users = array("jamesm"=>"");
        if (empty($_SERVER["PHP_AUTH_DIGEST"])) {
            header("HTTP/1.1 401 Unauthorized");
            header("WWW-Authenticate: Digest realm=\"{$realm}\",qop=\"auth\",nonce=\"".uniqid()."\",opaque=\"".md5($realm)."\"");
            return false;
        }
        if (!($data = http_digest_parse($_SERVER["PHP_AUTH_DIGEST"])) || !isset($users[$data["username"]]))
            return false;
        $A1 = md5($data["username"] . ":{$realm}:{$users[$data["username"]]}");
        $A2 = md5($_SERVER["REQUEST_METHOD"].":{$data["uri"]}");
        $valid_response = md5("{$A1}:{$data["nonce"]}:{$data["nc"]}:{$data["cnonce"]}:{$data["qop"]}:{$A2}");
        if ($data["response"] != $valid_response)
            return false;
        return true;
    }
    function logout(){
        unset($_SERVER["PHP_AUTH_DIGEST"]);
        return true;
    }

我还需要添加到注销功能以完成此操作.

如果我改变了它的作用,但我不希望它被改变.

在绘制和移动模型时如何使用z轴？

我目前的代码中有以下内容:

var canvas = {
    obj: document.querySelector("canvas"),
    models: [{
        start: [10, 10, 10],
        end: [1, 20, 20],
        color: "silver",
    },{ start: [30, 30, 30],
        end: [10, 1, 10],
        color: "silver",
    },{ start: [60, 60, 60],
        end: [10, 10, 10],
        color: "silver",
    }],
    data: {},
    draw: (function () {
        if (this.obj.getContext) {
            this.data.ctx = this.obj.getContext('2d');
            this.models.forEach(function () {
                canvas.data.ctx.fillStyle = this.color;
                canvas.data.ctx.fillRect(this["start"][0], this["start"][1], this["end"][0], this["end"][1]);
            }));
        }
        return this
    })
}.draw()

我知道3d可以在2d画布中使用,例如Pre3D库

所以我要做的是拥有一个商品的模型,并能够在3D中平移和环顾四周...我仍然不知道如何移动一切,但现在我要求如何获得z轴那里...然后我会问如何移动画布......

由于我的登录不起作用,我使用PHP和JavaScript这样做.

PHP:

$users = sql("SELECT * FROM USERS WHERE SITE_ID='${CONFIG["ID"]}'");
if($_REQUEST["logindata"]){
    $logindata = $_REQUEST["logindata"];
    $now = array_shift(explode(" ",microtime()));
    if($_REQUEST["time"] < strtotime("+10 sec",$now) && $_REQUEST["time"] > strtotime("-10 sec",$now))
        exit(json_encode(array("TYPE"=>"FUNCTION","FUNCTION"=>"(\$login.failed(\"Time out for this request.. (Go away bots)\"))")));
    foreach($users as $user){
        if(hash_hmac("sha1",$user["LOGIN_SALT"],hash_hmac("sha1",$_SERVER["REMOTE_ADDR"],$_REQUEST["time"])) == $logindata){
            $_SESSION = $user;
            $_SESSION["ACTIVE_IP"] = $IP;
            sql("UPDATE USERS SET ACTIVE_IP='${IP}' WHERE LOGIN_SALT='${user["LOGIN_SALT"]}'",0);
            $result = json_encode(array("TYPE"=>"FUNCTION","FUNCTION"=>"(\$login.success())"));
        }
    }
    !$result ? $result = json_encode(array("TYPE"=>"FUNCTION","FUNCTION"=>"(\$login.failed())")) : void;
}

JavaScript的:

    login: (function () {
        $("#ajax_loading").fadeIn("fast");
        $("[type=submit]").fadeOut("fast");
        $tmp.time = "" + (new Date()).valueOf();
        return …
