我正在尝试使用Api平台和Vich Uploader捆绑包上传文件。当我用多部分/表单数据和要附加图像文件的实体的Id发送POST请求时，我的实体得到了200的响应。但上传的文件不会上传到目标目录，生成的文件名也不会持久存在。没有错误，没有任何线索，没有任何想法。
这是我的代码：

正如你所看到的，一切都很好。找到了合适的组织。甚至logoFile字段也充满了上传的图片。但上传的文件没有移动到目的地。logoPath包含旧的徽标文件名。
正如我所说，没有错误。请帮我弄清楚在哪里挖。
VichUploaderBundle使用prePersist和preUpdate钩子在条令事件监听器中进行上传处理。在你的案例中，问题是，从学说的角度来看，没有持久性的财产发生变化。由于没有更改，因此不会调用上传侦听器。
一个简单的解决方法是在上传文件时始终更改持久属性。我将updatedAt添加到您的实体和方法updateLogo中，以将所需的logoFile和updatedAt更改保持在一起。

我目前正在进行一个允许用户上传媒体文件的项目。
我丢弃了维克的包裹。Api平台是面向应用程序/ld+json的。
相反，我让用户提供一个base64编码的内容文件(即，只有可读字符的字符串表示(。
我得到的唯一对应结果是，在http传输过程中，文件大小增加了约30%。老实说，这并不重要。
我建议你做一些类似下面代码的事情。
组织控制器--使用-->组织1<gt--->0..1图像对象
徽标(注意$encodingFormat属性上的断言(：
<?php
declare(strict_types=1);
namespace AppEntity;
use ApiPlatformCoreAnnotationApiProperty;
use ApiPlatformCoreAnnotationApiResource;
use DoctrineORMMapping as ORM;
use SymfonyComponentSerializerAnnotationGroups;

private $encodingFormat;
// getters and setters, nothing specific here
您剥离的组织类，声明OrganizationController:
<?php
namespace AppEntity;
use ApiPlatformCoreAnnotationApiResource;
use AppRepositoryOrganizationRepository;
use DoctrineORMMapping as ORM;
use SymfonyComponentSerializerAnnotationGroups;
use SymfonyComponentValidatorConstraints as Assert;
use AppControllerOrganizationController;
/**
* @ApiResource(
* normalizationContext={
"groups" = {"organization:get"}
* },
* denormalizationContext={
"groups" = {"organization:post"}
* },
* collectionOperations={
"get",
* "post" = {
* "controller" = OrganizationController::class
* }
* }
* )
* @ORMEntity(repositoryClass=OrganizationRepository::class)
*/
class Organization
{
/**
* @ORMId()
* @ORMGeneratedValue()
* @ORMColumn(type="integer")
* @Groups({"organization:get"})
*/
private $id;
/**
* @var string
* @ORMColumn(type="string", length=100, unique=true)
* @Groups({"organization:get", "organization:post"})
*/
private $slug;
/**
* @var null|ImageObject
* @AssertValid()
* @ORMOneToOne(targetEntity=ImageObject::class, cascade={"persist", "remove"})
* @Groups({"organization:get"})
*/
private $logo;
/**
* @var string the logo BLOB, base64-encoded, without line separators.
* @Groups({"organization:post"})
*/
private $b64LogoContent;
// getters and setters, nothing specific here...
}
请注意$logo和$b64LogoContent属性的序列化组。
然后控制器(动作类(，以便解码、分配和写入徽标内容。
<?php
namespace AppController;
use AppEntityImageObject;
use AppEntityOrganization;
use finfo;
/**
* Handle the base64-encoded logo content.
*/
class OrganizationController
{
public function __invoke(Organization $data)
{
$b64LogoContent = $data->getB64LogoContent();
if (! empty($b64LogoContent)) {
$logo = $this->buildAndWriteLogo($b64LogoContent);
$data->setLogo($logo);
}
return $data;
}
private function buildAndWriteLogo(string $b64LogoContent): ImageObject
{
$logo = new ImageObject();
$content = str_replace("n", "", base64_decode($b64LogoContent));
$mimeType = (new finfo())->buffer($content, FILEINFO_MIME_TYPE);
$autoGeneratedId = $this->createFileName($content, $mimeType); // Or anything to generate an ID, like md5sum
$logo->setName($autoGeneratedId);
$logo->setContentUrl("/public/images/logo/$autoGeneratedId");
$logo->setEncodingFormat($mimeType);
// check the directory permissions!
// writing the file should be done after data validation
file_put_contents("images/logo/$autoGeneratedId", $content);
return $logo;
}
private function createFileName(string $content, string $mimeType): string
{
if (strpos($mimeType, "image/") === 0) {
$extension = explode('/', $mimeType)[1];
} else {
$extension = "txt";
}
return time() . ".$extension";
}
}
它检查所提供的标志是否是一个"标志"；微小图像"；对于ImageObject类的@Assert注释(encodingFormat、width、height等(，它们由Organization:：$logo属性的@Assert\Valid批注触发。
这样，您就可以通过发送一个HTTPPOST/organizations请求来创建一个带有徽标的组织。
