在 digitalocean 的 ubuntu 服务器中使用 php 无法上传图像？

Question

即使在将权限更改为 777 之后，使用 PHP 中 ubuntu 服务器中的 PHP 也无法上传图片，并且我的代码输出显示图片已上传？之前它显示未授予权限，所以我使用 chmod 777 ./Images.

更改了此目录的权限

<?php
    require_once '../config.php';
    require_once '../function2.php';

    if ($_SERVER['REQUEST_METHOD']=="POST") {

        /*foreach($_POST as $key => $value) {
            $params[$key] = $value;
        }*/

        $isImage = isset($_FILES['imgUrl']['tmp_name']);

        if ($isImage) {
            $upload_dir ="../Images/";
            echo "upload_dir: " . $upload_dir . "<br>";
            if (file_exists($upload_dir)) {
                if (is_writable($upload_dir)) {
                    $target = $upload_dir; //"dirname(__FILE__)" . "photos/";
                    $target = $target . 'Visnu.png';
                    $moved = move_uploaded_file($_FILES['imgUrl']['name'], "$target");
                    echo "isMoved: " . $moved;
                } else {
                    echo 'Upload directory is not writable<br>';
                }
            } else {
                echo 'Upload directory does not exist.<br>';
            }
            echo $target . "<br>";
            //  echo dirname(__FILE__)."<br>";
            echo "Upload: " . $_FILES["imgUrl"]["name"] . "<br>";
            echo "Type: " . $_FILES["imgUrl"]["type"] . "<br>";
            echo "Size: " . ($_FILES["imgUrl"]["size"] / 1024) . " kB<br>";
            echo "Stored in: " . $_FILES["imgUrl"]["tmp_name"];
        }

        /*$url = $config['URLS']['API_PATH'] . $config['URLS']['ADD_USER_FORM'];

        echo $url;
        echo json_encode($params);

        $str = sendPostRequestWithImage($url, $params);

        echo "res: " . $str;

        $res = json_encode($str);

        if ($res['status']=='ok') {
            //header("location: ../signup-msg.php?success=0");
        }
        else {
            //header("location: ../signup-msg.php?success=1");
        }*/

    }
    else {
        header('location: ../404.php');
    }
?>

在你的代码中你有：

$moved = move_uploaded_file($_FILES['imgUrl']['name'], "$target");

密钥必须是 tmp_name 而不是 name

name 是用户电脑上原始文件的密钥。 tmp_name 是服务器上文件的 (tmp) 名称
