获得FileLoaderLoadException symfony的

Question

我是新来Symfony.I正在努力学习中Symfony.I文件上传我得到以下错误：

（3/3）FileLoaderLoadException 文件“d：\ WAMP \ WWW \ symfony_project \ app/config \ services.yml“不包含D：\ wamp \ www \ symfony_project \ app/config \ services.yml中的有效YAML（正在从D：\ wamp \ www \ symfony_project \ app导入/config\config.yml“）。

config.yml

parameters: 
brochures_directory: '%kernel.symfony_project%/../web/uploads/brochures' 

services.yml

FileUploader.php

namespace AppBundle\Service; 

use Symfony\Component\HttpFoundation\File\UploadedFile; 

class FileUploader 
{ 
    private $targetDir; 

    public function __construct($targetDir) 
    { 
     $this->targetDir = $targetDir; 
    } 

    public function upload(UploadedFile $file) 
    { 
     $fileName = md5(uniqid()).'.'.$file->guessExtension(); 

     $file->move($this->getTargetDir(), $fileName); 

     return $fileName; 
    } 

    public function getTargetDir() 
    { 
     return $this->targetDir; 
    } 
}

Answer 1

由于错误说，services.yml无效YAML。本着targetDir之前删除$标志：

 $targetDir: '%brochures_directory%' 

因此，这将是：

AppBundle\Service\FileUploader: 
    arguments: 
     targetDir: '%brochures_directory%' 

我想，这是你的问题，但我不能肯定，因为我不知道怎么看起来整个做这个文件的内容。

Answer 2

您services.yml不包含有效的YAML（错误信息不能得到更清晰;））

尝试这种代码：

/***/ 
admin.blog_post: 
    class: AppBundle\Admin\BlogPostAdmin 
    arguments: [~, AppBundle\Entity\BlogPost, ~] 
    tags: 
     - { name: sonata.admin, manager_type: orm, label: Blog post } 
    public: true 

admin.file_uploader: 
    class: AppBundle\Service\FileUploader 
    arguments: [~, '%brochures_directory%', ~] 

Answer 3

变化

parameters: 
brochures_directory: '%kernel.symfony_project%/../web/uploads/brochures' 

至

parameters: 
    brochures_directory: '%kernel.symfony_project%/../web/uploads/brochures' 

Answer 4

现在应该工作：

→ ﹍AppBundle\Service\FileUploader: 
    arguments: 
     targetDir: '%brochures_directory%'

Answer 5

您在AppBundle\Service\FileUploader前面有空间在未来使用YAML棉短绒：

bin/console lint:yaml app/config/services.yml
