從表單 POST 上傳 PHP Curl 檔案
使用 POST 表單上傳檔案可能具有挑戰性，尤其是在伺服器端使用 cURL 時。要解決這個問題，請考慮以下方法：
伺服器端cURL 實作
要處理檔案上傳並透過cURL 發送它們，您可以利用PHP 的$_FILES 超全局，它提供有關上傳文件的資訊。以下是示範流程的程式碼片段：
if (isset($_POST['upload'])) {
$fileKey = 'image'; // Assuming your file input has 'image' as its name
// Retrieve file information
$tmpFile = $_FILES[$fileKey]['tmp_name'];
$fileName = $_FILES[$fileKey]['name'];
// Prepare cURL parameters
$postFields = ['file' => '@' . $tmpFile, /* Other post parameters if needed */];
$url = 'https://example.com/curl_receiver.php'; // URL to send the file to
// Initialize and configure cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Execute cURL request
$result = curl_exec($ch);
// Handle cURL response
if (curl_errno($ch)) {
// Handle error
} else {
// Success, do further processing with $result
}
// Close cURL connection
curl_close($ch);
}接收腳本 (curl_receiver.php)
<?php
// Handle incoming POST data
if (!empty($_FILES)) {
// Retrieve file information
$tmpFile = $_FILES['file']['tmp_name'];
$fileName = $_FILES['file']['name'];
// Process and save the uploaded file
// ...
// Send response to the client
echo json_encode(['status' => 'success']);
} else {
// Handle error, no file uploaded
echo json_encode(['status' => 'error', 'message' => 'No file uploaded']);
}
