func generateBoundaryString() -> String 
{ 
    return "Boundary-\(UUID().uuidString)" 
}

在PHP

if (move_uploaded_file($_FILES['file']['tmp_name'], "image.png")) { 
echo "File uploaded: ".$_FILES["file"]["name"]; }

你的第二個屏幕截圖顯示問題：這是帶有PHP警告的服務器回覆，apache/php用戶沒有權限將上傳的圖像移動到targetdirectory中，這將成爲根目錄（/） - 因爲您沒有指定目錄/路徑在哪裏存儲圖像。請參閱PHP文檔的Example 1。

所以，你應該建立一個上傳目錄（如MKDIR /Appli.../htdocs/uploads，設置正確的權限（用於開發目的搭配chmod -R 777個上傳），並在你的PHP目標目錄指定：

if (move_uploaded_file($_FILES['file']['tmp_name'], "/Appli.../htdocs/uploads/image.png")) { ...

它不是在PHP工作如果（move_uploaded_file（$ _ FILES [ '文件'] [ 'tmp_name的值']，「/Applications/XAMPP/xamppfiles/htdocs/image.png」））{ echo「File uploaded：」。$ _ FILES [「file」] [「name」]; \t } 我運行應用程序，但顯示 https://www.dropbox.com/s/gd87ym4yfr0lao3/%E0%B8%88%E0%B8%B1%E0%B8%9A%E0%B8%A0%E0%B8 ％B2％E0％B8％9E％E0％B8％AB％E0％B8％99％E0％B9％89％E0％B8％B2％E0％B8％88％E0％B8％AD％202559-09-21 ％20％E0％B9％80％E0％B8％A7％E0％B8％A5％E0％B8％B2％2017.14.01.png？dl = 0 – user3592917

您現在將圖像直接保存到您的htdocs/Applications/XAMPP/xamppfiles/htdocs /請嘗試以下操作： –

對不起，我在這裏插入了全部評論：您現在將映像直接保存到您的htdocs文件夾：/ Applications/XAMPP/xamppfiles/htdocs，請在* * terminal **： mkdir/Applications/XAMPP/xamppfiles/htdocs/uploads && chmod -R 777/Applications/XAMPP/xamppfiles/htdocs/uploads 然後在** PHP **上使用： if（move_uploaded_file（$ _ FILES ['file'] ['tmp_name']，「/Applications/XAMPP/xamppfiles/htdocs/uploads/image.png」）） –
