使用php从dart上传多个文件到服务器端

import 'dart:io';
import 'dart:convert';

void uploadFiles() async {
  var uri = Uri.parse('http://your-server.com/upload.php');
  var request = await HttpClient().postUrl(uri);
  request.headers.set('content-type', 'multipart/form-data; boundary=XXX');

  var formData = FormData.from({
    'files': [
      await http.MultipartFile.fromPath('file1.jpg', 'path/to/file1.jpg'),
      await http.MultipartFile.fromPath('file2.jpg', 'path/to/file2.jpg'),
    ],
  });

  request.write(formData.toString());
  var response = await request.close();

  if (response.statusCode == 200) {
    print('Files uploaded successfully');
  } else {
    print('Failed to upload files');
  }
}

<?php
$uploadDir = 'uploads/';

if (isset($_FILES['files'])) {
    $files = $_FILES['files'];
    $fileCount = count($files['name']);

    for ($i = 0; $i < $fileCount; $i++) {
        $fileName = $files['name'][$i];
        $fileTmpName = $files['tmp_name'][$i];
        $fileSize = $files['size'][$i];
        $fileType = $files['type'][$i];

        $uploadPath = $uploadDir . basename($fileName);

        if (move_uploaded_file($fileTmpName, $uploadPath)) {
            echo "File $fileName uploaded successfully.\n";
        } else {
            echo "Failed to upload file $fileName.\n";
        }
    }
} else {
    echo "No files uploaded.\n";
}
?>

$fileName = uniqid() . '_' . basename($files['name'][$i]);
$uploadPath = $uploadDir . $fileName;

$allowedTypes = ['image/jpeg', 'image/png'];
if (in_array($fileType, $allowedTypes)) {
    // 处理文件上传
} else {
    echo "Invalid file type.\n";
