Php 正在上载文件，但名称为空

我有一个IOS应用程序，它使用PHP作为我的API。我的文件上传工作正常，但文件名没有附加到文件中。我已经在我的应用程序中镜像了其他页面，但它仍然不工作，尽管其他页面工作正常。我可以在服务器上看到该文件，但名称是notes-.jpg。它不是根据代码将puuid附加到名称。我在ViewController上实现了不起作用的MessageKit（以防万一）。下面是我的代码，我觉得我在大海捞针。代码有点草率（请不要判断）

PHP上传文件

<?php
if (!empty($_REQUEST["uuid"])) {
    $id = htmlentities($_REQUEST["id"]);
    $recipient = htmlentities($_REQUEST["recipient"]);
    $recipient_id = htmlentities($_REQUEST["recipient_id"]);
    $uuid = htmlentities($_REQUEST["uuid"]);
    $puuid = htmlentities($_REQUEST["puuid"]);
    $text = htmlentities($_REQUEST["text"]);
    $sender = htmlentities($_REQUEST["sender"]);
    $sender_id = htmlentities($_REQUEST["sender_id"]);

if (isset($_FILES['file']) && $_FILES['file']['size'] > 1) {

    $folder = "/home/xxxxx/public_html/notes/" . $uuid;

    // if no posts folder, create it
    if (!file_exists($folder)) {
        mkdir($folder, 0777, true);
    }

    $picture = $folder . "/" . basename($_FILES["file"]["name"]);
            chmod($picture,0777);

    if (move_uploaded_file($_FILES["file"]["tmp_name"], $picture)) {

        $path = "http://localhost/notes/" . $uuid . "/notes-" . $puuid . ".jpg"; 

        $returnArray["message"] = "Post has been made with picture";

        $returnArray["path"] = $path;
        $returnArray["status"] = "200";
    } else {
        $returnArray["message"] = "Post has been made without picture";
        $path = "";
    }
        $result=$access->insertMessage($recipient, $recipient_id, $uuid, $sender,$sender_id, $text, $path);
       // STEP 2.5 If posts are found, append them to $returnArray
       if (!empty($result)) {

        $returnArray["message"] = $result;
       $result = $access->updatebadge($recipient_id);
}
    else {
    $returnArray["message"] = "Couldnt insert". $puuid ."";

    }



 // if data is not passed - show posts except id of the user

}
else {

    $username = htmlentities($_REQUEST["username"]);
    $uuid = htmlentities($_REQUEST["uuid"]);
    $recipient_id = htmlentities($_REQUEST["recipient_id"]);

    $message = $access->conversation($username, $uuid, $recipient_id);

    if (!empty($message)) {
        $returnArray["message"] = $message;
    }

}

}
$access->disconnect();
echo json_encode($returnArray);



?>

我想出来了。Swift中的正文和标题不正确，未发送正确的文件名

我把尸体改成：

// web development and MIME Type of passing information to the web server
  let boundary = "Boundary-\(NSUUID().uuidString)"
  request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")

  // access / convert image to Data for sending to the server
  var data = Data()

  // if picture has been selected, compress the picture before sending to the server
  if image != nil {
    data = image.jpegData(compressionQuality: 0.5)!
  }

  // building the full body along with the string, text, file parameters
  request.httpBody = Helper().body(with: parameters, filename: "notes-\(puuid).jpg", filePathKey: "file", imageDataKey: data, boundary: boundary) as Data

你能在服务器上找到上传的文件吗？你能在print（）中找到文件名吗？@sayooj我能根据时间戳在服务器上找到文件。但是它的名字是notes-.jpg，它没有根据code@angel在createparams函数中，我得到了文件名，但在UploadImages中没有，这里调用的

htmlentities（）

数量惊人。由于这些都与HTML显示转义无关，因此您根本不应该调用此函数。您是否能够在服务器中找到上载的文件？您可以在print（）中获得文件名？@sayooj我可以根据时间戳在服务器上找到该文件。但是它的名字是notes-.jpg，它没有根据code@angel在createparams函数中，我得到了文件名，但在UploadImages中没有，这里调用的
