使用vue axios和PHP上传多个文件 - 只上传一个文件

Question

我正在尝试使用 vue 和 axios 创建多个文件上传。我的问题是只有ine 文件会上传到服务器。这是我使用的代码：模板代码<input type="file" name="images[]" multiple ref="images" @change="handleUpload()">JS代码//this is part of the handleUpload() vue method.let formData = new FormData();for(let i;i < $refs.images.files.length; i++){ let file = this.$refs.images.files[i]; formData.append('image', file);}axios.post('/upload', formData, { header: { 'Content-Type': 'multipart/form-data' } }).then( (response) => console.log(response, response.data) ).catch( (error) => console.log(error) ); PHP服务器代码// I'm using slim 4 and sirius upload to manage the file validation/uploaduse Psr\Http\Message\ResponseInterface as Response;use Psr\Http\Message\ServerRequestInterface as Request;use Psr\Http\Message\UploadedFileInterface;use Slim\Factory\AppFactory;use Sirius\Upload\Handler as UploadHandler;require __DIR__ . '/vendor/autoload.php';$app = AppFactory::create();$app->post('/platform/api/v1/compress', function(Request $request, Response $response){    $uploadHandler = new UploadHandler('/uploads');            $uploadHandler->addRule('extension', ['allowed' => ['jpg', 'jpeg', 'png']]);           $result = $uploadHandler->process( $request->getUploadedFiles() );                // handle single input with single file upload        if( $result->isValid() ){            $result->confirm();                               $url = ["master_image_url" => "/uploads/".$result->name];            $response->getBody()->write(json_encode($url));        }    return $response;});$app->run();如何上传多个文件？也许我需要修改代码？

Answer 1

append尝试将函数中的“image”更改为“image[]”

例子：

for(let i;i < $refs.images.files.length; i++){

 let file = this.$refs.images.files[i];

 formData.append('image[]', file);

}

在服务器中

$uploadedFiles=$request->getUploadedFiles();

foreach ($uploadedFiles['image'] as $uploadedFile) {

        if ($uploadedFile->getError() === UPLOAD_ERR_OK) {

           

        }

    }
