symfony4上傳表單上沒有handleResquest方法但帶有xhr物件html

你好，我想用 xhr html 請求執行我的進度條，用 symfony 4 簡單提交是不夠的

我嘗試使用表單資料在 php 方法上執行 xhr html 請求，并使用 e.preventDefault() 指令防止事件默認，但它不起作用。我不知道為什么 Symfony 工具列說我沒問題（代碼 200 ). 但我無法使用 php 獲取輸入檔案物件。我在這里發布我的代碼。

var uploadForm=document.getElementById("form2");
uploadForm.addEventListener("submit", uploadFile);
function uploadFile(e) {
    e.preventDefault();
    var inputFile=document.getElementById("user_file").files[0];
    let uploadDataForm = new FormData();
    uploadDataForm.append('file',inputFile);
    for (var value of uploadDataForm.values()) {
        console.log(value);
    }
 try {
        const xhr = new XMLHttpRequest();
        xhr.open('POST', '/');
        xhr.upload.addEventListener('progress', e => {
            const percent = e.lengthComputable ? (e.loaded / e.total) * 100 : 0;
            progressBarFill.width = percent.toFixed(2)
            progressBarText.textContent=percent.toFixed(2);
        });
        xhr.setRequestHeader("Content-Type", "multipart/form-data");
        xhr.send(uploadDataForm);


    }
    catch (error){
        console.error(error);
    }





}

 /**
 * @Route("/", name="acceuil")
 * @param Request $request
 * @return \Symfony\Component\HttpFoundation\RedirectResponse|\Symfony\Component\HttpFoundation\Response
 */
public function index(Request $request,ProductManager $productManager)
{
    /** @var User $user */
    $user = new User();
    $file = $request->query->get('file');
    try {
        /** @var UploadedFile $task */
        $task = $file;
        if ($task === null) exit;
        $destination = $this->getParameter('files_directory');
        $originalFilename = pathinfo($task->getClientOriginalName(), PATHINFO_FILENAME);
        $newFilename = Urlizer::urlize($originalFilename) . '-' . uniqid() . '.' . $task->guessExtension();


        //$fileName = md5(uniqid()).'.'.$file->guessClientExtension();
        $task->move(
            $destination,
            $newFilename
        // $this->getParameter('files_directory'),


        );
        return $this->redirectToRoute('acceuil');
    } catch (\Exception $e) {
        echo $e->getMessage();
    }

}

我無法保存我的輸入檔案。

   <div class="col-12">
    {{ form_start(form2,{'attr': {'id': 'form2'}})  }}
    {{ form_row(form2.file,{attr:{'placeholder':'veuillez importer votre CV'}}) }}
    {{ form_widget(form2) }}

    <button type="submit" class="btn btn-primary">Enregistrer!</button>
    {{ form_end(form2) }}
        <div class="progress-bar" id="progressBar">
            <div class="progress-bar-fill">
                <span class="progress-bar-text">0</span>
            </div>
        </div>
    </div>
    {% if fichier is defined %}
        {%  for fich fichier %}
            <div>{{ fich }}</div>
        {% endfor %}
    {% endif %}

我今天嘗試使用 axios 技術，但它再次不起作用，在這里，您將看到我的代碼 js 和 php：

js：

    $('document').ready(function () {
    const axios = require('axios').default;
    const progressBarFill = document.getElementsByClassName('progress-bar-fill');
    const progressBarText = document.getElementsByClassName('progressBarText');
    var uploadForm = document.getElementById("form2");

    $('uploadForm').on('Submit', function (e) {
        e.preventDefault();
        var inputFile = document.getElementById("user_file").files[0];
        let uploadDataForm = new FormData();
        uploadDataForm.append('file', inputFile);
        var config = {
            onUploadProgress: function (e) {
                const percent = e.lengthComputable ? (e.loaded / e.total) * 100 : 0;
                progressBarText.textContent = percent.toFixed(2);
            },
            headers: ('X-Requested-width','XMLHttprequest')
        };

        axios.post('/', uploadDataForm, config).then(function (response) {

            console.log(response.data);
        });
    });
});
// uploadForm.addEventListener("submit", uploadFile);
// function uploadFile(e) {

你可以幫幫我嗎 ？

我找到了解決方案。

    const progressBarFill = document.getElementsByClassName('progress');
const progressBarText = document.getElementsByClassName('progress-bar');
var uploadForm = document.getElementById("form2");
uploadForm.addEventListener("submit", uploadFile);
function uploadFile(e) {
    e.preventDefault();
    var inputFile=document.getElementById("user_file").files[0];
    let uploadDataForm = new FormData();
    uploadDataForm.append('file',inputFile);
    for (var value of uploadDataForm.values()) {
        console.log(value);
    }
    try {
        const xhr = new XMLHttpRequest();
        xhr.open('POST', '/uploadAjax');
        xhr.upload.addEventListener('progress', e => {
            const percent = e.lengthComputable ? (e.loaded / e.total) * 100 : 0;
            $(".progress-bar").width(percent  '%');
            $(".progress-bar").html(percent '%');
        });

        xhr.send(uploadDataForm);




        console.log(response);
}




    }
    catch (error){
        console.error(error);
    }
}

和 php 代碼：

     /**
     ** @Route("/uploadAjax", name="uploadAjax")
     * @param Request $uneRequete
     * @return void
     */
    public Function uploadAjax(Request $uneRequete){

            try {
                $test = 'c bon';
                $req = $uneRequete;

                /** @var UploadedFile $file */
                $file = $uneRequete->files->get('file');

                if ($file === null) exit;
                $destination = $this->getParameter('files_directory');
                $originalFilename = pathinfo($file->getClientOriginalName(), PATHINFO_FILENAME);
                $newFilename = Urlizer::urlize($originalFilename) . '-' . uniqid() . '.' . $file->guessExtension();

                //$fileName = md5(uniqid()).'.'.$file->guessClientExtension();
                $file->move(
                    $destination,
                    $newFilename

                );
            }
            catch (\Exception$e){
                echo $e->getMessage();
            }


       return $this->render('acceuil/index.html.twig',['uneRequete'=>$req]);
    }
}
