我正在尝试将一个项目进行Dockerize，前端和后端是分开的：如果我用命令启动Symfony和VueJS来启动这两个项目（在同一个根目录下，但不同的文件夹中），它可以正常工作。但是如果我尝试将所有内容都进行Dockerize，我会得到CORS错误。
我正在使用：

• 第一个月
• Vue 3.2.13个
• PHP 8.1个
• Docker 4.24.2个

在根项目中，我有几个文件和3个文件夹：客户端、服务器和nginx
这是来自服务器的Docker：

FROM php:8.1-fpm

# Copy composer.lock and composer.json into the working directory
COPY composer.lock composer.json /var/www/html/

# Set working directory
WORKDIR /var/www/html/

# Install dependencies for the operating system software
RUN apt-get update && apt-get install -y \
    build-essential \
    libpng-dev \
    zip \
    vim \
    git \
    curl

# Install extensions for php
RUN docker-php-ext-install pdo_mysql
RUN docker-php-ext-install gd

# Install composer (php package manager)
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# Copy existing application directory contents to the working directory
COPY . /var/www/html

# Expose port 7999 and start php-fpm server (for FastCGI Process Manager)
EXPOSE 7999

CMD ["php-fpm"]

字符串
在.env文件中，我看到了下面一行：

###> nelmio/cors-bundle ###
CORS_ALLOW_ORIGIN='^https?://(localhost|127\.0\.0\.1)(:[0-9]+)?$'
###< nelmio/cors-bundle ###

型
和内部配置/包/nelmio_cors.yaml

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']
        expose_headers: ['Link']
        max_age: 3600
    paths:
        '^/': null

型
在客户端部分，我得到了Docker：

FROM node:16 as build-stage
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY ./ .
RUN npm run build

FROM nginx as production-stage
EXPOSE 3000
RUN mkdir /app
COPY nginx.conf /etc/nginx/conf.d/default.conf
COPY --from=build-stage /app/dist /app

型
和nginx.conf文件

server {
  listen 3000;

  location / {
    root /app;
    index index.html index.htm;
    try_files $uri $uri/ /index.html;
  }
}

型
在nginx文件夹中，我得到了两个文件：这是默认的.conf

upstream frontend {
  server frontend:3000;
}

#upstream backend {
  #server backend:7999;
#}

server {
  listen 80;
  index index.php index.html;
  error_log  /var/log/nginx/error.log;
  access_log /var/log/nginx/access.log;
  root /var/www/html/public;

  location / {
    proxy_pass http://frontend;
  }

  location /api {
    try_files $uri $uri/ /index.php?$query_string;
    gzip_static on;
  }

  # Nginx Pass requests to PHP-FPM
  location ~ \.php$ {
    #try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    #fastcgi_pass backend;
    fastcgi_pass localhost:7999;
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param PATH_INFO $fastcgi_path_info;
  }
}

型
码头档案是

FROM nginx
COPY ./default.conf /etc/nginx/conf.d/default.conf

最后，在根项目中，docker-compose.yml是

我收到CORS错误或NS_ERROR_DOM_BAD_URI x1c 0d1x
有什么建议吗？
