在Unity3D（C#）中创建文件夹并将文本文件上载到服务器（php）

我所拥有的：

我有一个简单的模块，可以将字符串转换为文本文件并存储在我的服务器中

C#/Unity Code

private IEnumerator UploadUserData(string _fileName)
{        
    string _data = ("With text name " + System.DateTime.Now.ToString ());
    string _postDataURL = "https://nameofserver.com/upload.php"

    WWWForm _form = new WWWForm ();
    _form.AddField ("name", _fileName);
    _form.AddField ("data", _data);      

    UnityWebRequest _wwwRequest = UnityWebRequest.Post (_postDataURL, _form);

    yield return _wwwRequest.Send ();

    while (!_wwwRequest.isDone)
    {   yield return null;}

    if (_wwwRequest.error != null)
    {
        Debug.Log (_wwwRequest.error);
    }
    else
    {
        Debug.Log ("Uploaded");
    }

    Debug.Log (_wwwRequest.downloadHandler.text);
}

服务器端PHP

 <?php    
if(isset($_POST['name']) && isset($_POST['data'])){
    file_put_contents($_POST['name'].".txt", $_POST['data']);      
    echo "uploaded.";
}else{
    echo "invalid file uploaded.";
}  

请求

我想建立一个系统，我可以上传文件到特定的文件夹。假设我想上传一个文本文件（filename.txt）到一个名为“Folder1”的文件夹中

来自php端

private IEnumerator UploadUserData(string _fileName)
{        
    string _data = ("With text name " + System.DateTime.Now.ToString ());
    string _postDataURL = "https://nameofserver.com/upload.php"

    WWWForm _form = new WWWForm ();
    _form.AddField ("name", _fileName);
    _form.AddField ("data", _data);      

    UnityWebRequest _wwwRequest = UnityWebRequest.Post (_postDataURL, _form);

    yield return _wwwRequest.Send ();

    while (!_wwwRequest.isDone)
    {   yield return null;}

    if (_wwwRequest.error != null)
    {
        Debug.Log (_wwwRequest.error);
    }
    else
    {
        Debug.Log ("Uploaded");
    }

    Debug.Log (_wwwRequest.downloadHandler.text);
}


如果文件夹“Folder1”不存在，php端应该创建它
然后将文本文件“filename.txt”上载到该文件夹

如果该目录中存在“Folder1”，那么我希望php
将文本文件“filename.txt”上载到现有文件夹的脚本
“文件夹1”


来自联合方

private IEnumerator UploadUserData(string _fileName)
{        
    string _data = ("With text name " + System.DateTime.Now.ToString ());
    string _postDataURL = "https://nameofserver.com/upload.php"

    WWWForm _form = new WWWForm ();
    _form.AddField ("name", _fileName);
    _form.AddField ("data", _data);      

    UnityWebRequest _wwwRequest = UnityWebRequest.Post (_postDataURL, _form);

    yield return _wwwRequest.Send ();

    while (!_wwwRequest.isDone)
    {   yield return null;}

    if (_wwwRequest.error != null)
    {
        Debug.Log (_wwwRequest.error);
    }
    else
    {
        Debug.Log ("Uploaded");
    }

    Debug.Log (_wwwRequest.downloadHandler.text);
}

我应该如何提及Unity webrequest中的文件夹名称

非常感谢您抽出时间。非常感谢
 就像我在IRC上对你咆哮一样，你应该避免让你的文件路径由用户或用户可访问的API提供的数据指定，甚至包括这些数据

我会提出以下建议：

// always have something define the absolute path to your application root,
// then build your paths/filenames relative to that.
// let's say this is /usr/local/myapp/config/config.php
define('APPROOT', realpath(__DIR__ . '/..')); // APPROOT == '/usr/local/myapp'
define('USERUPLOADS', APPROOT . '/user_uploads');

// userid SHOULD be something you control, not a username or anything specified
// by the user. the focus is to prevent malformed and/or malevolent user data
// from breaking out of the upload directory sandbox.
function acceptUploadedUserData($userid, $name, $data) {
    $userdir = USERUPLOADS . '/' . $userid;
    if( ! is_dir($userdir) ) {
        mkdir($userdir);
    }
    // just kinda baseline "OK"
    if( strpos('..', $name) !== false || strpos('/', $name) !== false ) {
        throw new Exception('Specified name cannot contain .. or /');
    }
    file_put_contents($userdir . '/' . $name, $data);

    // better yet don't let the user have *any* control over any part of the path
    // but also allows you to specify *any* string as the filename.
    file_put_contents($userdir . '/' . md5($name), $data);
}

acceptUploadedUserData($_SESSION['user_id'], $_POST['name'], $_POST['data']);

该文件夹名称可能是PHP中的
文件内容
调用的一部分。@Draco18s非常感谢您的评论。我对php完全陌生，因此你能帮我写一段代码吗？谢谢不幸的是，我自己对PHP知之甚少。
