通過curl發送文件到plupload chunked

Question

我的一個客戶需要一個文件（圖片）通過捲髮（php-curl） 發送到plupload php腳本。問題是該文件似乎應該與塊一起發送。

你能告訴我如何用PHP發送文件到這個腳本？

這裏是接受文件的上傳腳本文件。

我評論了PHP腳本的以下幾行，其中chunking似乎涉及到。當請求分塊參數不存在時，您會看到整個文件大小寫爲默認情況。

// $chunk is the index of the chunk being uploaded. 
// Considered as 0 if not present in the request (whole file, or fist chunk in chunking mode) 
$chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0; 

// $chunks is the number of upload chunks. 
// Considered as 0 (whole file, no chunking) if not present in the request 
$chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 0; 

// if handling the first chunk (or whole file) open temp file in create mode, else in append mode 
$out = @fopen("{$filePath}.part", $chunk == 0 ? "wb" : "ab"); 

// if not in chunking mode (!$chunks) or finished processing last chunk, rename the temp file to target nam 
if (!$chunks || $chunk == $chunks - 1) 

希望這將有助於

根據您的意見，當前頁面應該張貼的文件，用文件名defaultname.txt

<html> 
    <head> 
    <title>Upload Form</title> 
    </head> 
<body> 
<form enctype="multipart/form-data" action="/upload.php"; method="POST"> 
    <input type="text" name="name" size="20" value="defaultname.txt"/> <br /><br /> 
    <input type="file" name="file" size="20" /> <br /><br /> 
    <input type="submit" value="upload" /> 
</form> 
</body> 
</html>
