Question

我正在尝试

<link href="{{ asset('css/mystyle.css') }}"
      rel="stylesheet"/>

在我的树枝文件中进行渲染。但这给了我未捕获的PHP异常Twig_Error_Runtime：

“在呈现模板期间引发了异常（“资产清单文件“ /../public/build/manifest.json”不存在。”

当我使用

时，它确实可以工作

link href="css/mystyle.css"
          rel="stylesheet"/>

。以下是我的控制器：

    <?php

namespace App\Controller;

use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;

class WelcomeController extends AbstractController
{
    /**
     * @Route("/", name="welcome")
     */
    public function index()
    {
        return $this->render('welcome/index.html.twig');
    }
}

以下是我的树枝模板：

我该如何解决此问题？

Answer 1

执行以下命令：

yarn add --dev @symfony/webpack-encore

yarn add webpack-notifier --dev

yarn encore dev

它将生成manifest.json文件

Answer 2

yarn encore dev-server --hot创建manifest.json文件

Answer 3

尝试安装Assets Bundle：

composer require symfony/asset

Answer 4

manifest.json是Symfony 3.3中的新功能。

因此，您应该在配置文件中包含以下行：

// The url of the service 
$url = 'https://wsbexpress.dhl.com:443/sndpt/expressRateBook?WSDL';
// the soap operation which is called
$action = 'createShipmentRequest';

// the xml input of the service
$xmlrequest = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:rat="http://scxgxtt.phx-dc.dhl.com/euExpressRateBook/RateMsgRequest">

    <soapenv:Header>

     <wsse:Security soapenv:mustunderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">

            <wsse:Username>*********</wsse:Username>           
            <wsse:Password type="PasswordText">*******</wsse:Password>

            <wsu:Created>' . date('Y-m-d H:i:s') . '</wsu:Created>
         </wsse:UsernameToken>
      </wsse:Security>

try {

    // the soap client accepts options, we specify the soap version
    // The trace option enables tracing of request so faults can be backtraced.
    // The exceptions option is a boolean value defining whether soap errors throw exceptions of type SoapFault. 
    $opts = array(
        'ssl' => array(
            'verify_peer' => false,
            'verify_peer_name' => false,
            'allow_self_signed' => true
        )
    );
    $options = array(
        'encoding' => 'UTF-8',
        'verifypeer' => false,
        'verifyhost' => false,
        'soap_version' => SOAP_1_2,
        'trace' => 1,
        'exceptions' => 1,
        'connection_timeout' => 180,
        'stream_context' => stream_context_create($opts),
        'cache_wsdl' => WSDL_CACHE_NONE,
    );

    // create the soapclient and invoke __doRequest method
    $client = new SoapClient($url, $options);
    $output = $client->__doRequest($xmlrequest, $url, $action, 1);
} catch (SoapFault $fault) {
    echo "<h2>SOAP Fault!</h2><p>";
    echo "FaultCode: {$fault->faultcode} <br/>";
    echo "FaultString: {$fault->faultstring} <br/>";
    echo"</p/>";
}

echo "<h2>WSDL URL: </h2><p>";
echo $url;
echo "</p/>";

echo "<h2>Action: </h2><p>";
echo $action;
echo "</p/>";

echo "<h2>XMLRequest: </h2><p>";
echo $xmlrequest;
echo "</p/>";

if (!isset($output)) {
    echo "<h2>SOAP Fault!</h2><p>";
    echo "FaultCode: {$output->faultcode} <br/>";
    echo "FaultString: {$output->faultstring} <br/>";
} else {
    echo "<h2>Output: </h2><p>";
    file_put_contents('dhl.xml', $output);
    echo $output;
    echo "</p/>";
}

如果manifest.json不存在，则应创建它，如下所示：

{ “ css / app.css”：“ build / css / mystyle.b916426ea1d10021f3f17ce8031f93c2.css”， “ ...”：“ ...” }

Answer 5

我通过不使用json_manifest_path解决了这个问题：〜

通过在json_manifest_path前面添加“＃”来注释它并在“资产：”之后添加“〜”

nzCustomRequest

Answer 6

请记住，该问题被标记为 Symfony4 ！

我在导航栏，网站图标中添加徽标也遇到了同样的问题……

在Symfony4中，没有更多的 app 目录，因此没有 app / config / config.yml ！在Symfony4中， web 目录已不存在，但有新目录 public

正如@Bijaya所写，只需在公共位置指定 href 或 src 地址

就我而言，我有自己的徽标： myProjectName / public / logo_mom.png

在我的控制器中，我有：

/**
 * @Route("/", name="home")
 */
public function home() {
    return $this->render('blog/home.html.twig', [
        'title' => "Bienvenue",
        'logo_path' => "logo_mom.png",
        'logo_alt' => "logo alt description",
    ]);
}

以及在我的 home.html.twig 中：

{% block body %}
    <h1>{{ title }}</h1>
    <img src={{ logo_path }} alt={{ logo_alt}}>

以及在我的 template / base.html.twig 中：

<link rel="icon" type="image/x-icon" href="favicon.ico" />

因此，对于那些不具备Symfony先前版本知识而发现Symfony4的我来说，很高兴不需要资产功能或任何其他配置！

Answer 7

我通过不使用 json_manifest_path: ~

解决了这个问题

注释掉json_manifest_path，在它前面添加#并在~之后添加assets:

framework:
    assets: ~
        #json_manifest_path: '%kernel.project_dir%/public/build/manifest.json'

Symfony错误：“在呈现模板期间引发了异常”
