我的管理面板有一个问题，我的api没有问题，（可以发布和获取）但是当我想用管理面板创建或更新对象的时候，我有一个白色的表单： 我的api没有问题，（可以发布和获取）但是当我想用管理面板创建或更新对象时，我有一个白色的表格。屏幕

我也有这个警告在我的控制台。

Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.

谁能帮帮我？

我没有修改api平台的原生代码。

我的app.js是(REACT_APP_API_ENTRYPOINT =) https:/localhost:8443。):

import React from 'react';
import { HydraAdmin } from '@api-platform/admin';

export default () => <HydraAdmin entrypoint={process.env.REACT_APP_API_ENTRYPOINT}/>;

我的nelmio_cors.yaml在我的api中。

nelmio_cors:
    defaults:
        origin_regex: true
        allow_origin: ['%env(CORS_ALLOW_ORIGIN)%']
        allow_methods: ['GET', 'OPTIONS', 'POST', 'PUT', 'PATCH', 'DELETE']
        allow_headers: ['Content-Type', 'Authorization', 'Preload', 'Fields']
        expose_headers: ['Link']
        max_age: 3600
    paths:
        '^/': null

api中的一个实体的例子。

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * SupplierType
 *
 * @ORM\Table(name="supplier_type")
 * @ORM\Entity(repositoryClass="App\Repository\CustomEntityRepository")
 */
class SupplierType
{
    /**
     * @var int
     *
     * @ApiResource
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="SEQUENCE")
     * @ORM\SequenceGenerator(sequenceName="supplier_type_id_seq", allocationSize=1, initialValue=1)
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="code", type="string", length=100, nullable=false, unique=true)
     */
    private $code;

    /**
     * @var string
     *
     * @ORM\Column(name="label", type="string", length=100, nullable=false)
     */
    private $label;

    /**
     * @var \DateTime
     *
     * @ORM\Column(name="created", type="datetime")
     */
    private $created;

    /**
     * @var \DateTime
     *
     * @ORM\Column(name="updated", type="datetime")
     */
    private $updated;

    public function getId(): ?int
    {
        return $this->id;
    }

    public function getCode(): ?string
    {
        return $this->code;
    }

    public function setCode(string $code): self
    {
        $this->code = $code;

        return $this;
    }

    public function getLabel(): ?string
    {
        return $this->label;
    }

    public function setLabel(string $label): self
    {
        $this->label = $label;

        return $this;
    }

    public function getCreated(): ?\DateTimeInterface
    {
        return $this->created;
    }

    public function setCreated(\DateTimeInterface $created): self
    {
        $this->created = $created;

        return $this;
    }

    public function getUpdated(): ?\DateTimeInterface
    {
        return $this->updated;
    }

    public function setUpdated(\DateTimeInterface $updated): self
    {
        $this->updated = $updated;

        return $this;
    }
}

你没有分享任何代码，所以很难精确，但你可以尝试跟踪你的组件是否被挂载。

查看这篇博客文章，它可以提供关于这个问题的进一步（和更详细）的见解。https:/www.debuggr.ioreact-update-unmounted-component

另外这个链接上的公认答案可能也是相关的。React-hooks。无法在未安装的组件上执行React状态更新。
