码头化Django Rest+Angular项目中阻塞的CORS

今天我决定将现有的django rest+angular应用程序进行Dockerize。尽管CORS请求被阻止,但该网站仍按原样显示。

访问位于' http://localhost:8000/branches/1 “起源” http://localhost:3000 '已被CORS策略阻止:请求的资源上不存在'access control allow origin'头。

角度应用程序使用nginx进行固定。我在用 this 教程正在进行中(docker+compose文件如下所示)。

奇怪的是,我以前有过这个问题,通过使用 Djang Cors标题 包裹。随着 CORS_ORIGIN_ALLOW_ALL = True 这似乎不再解决问题了。

这是否与应用程序现在在容器中运行的事实有关?我将为项目提供dockerfiles以及下面的docker compose文件。但不确定它们是否相关。

角度项目的Dockerfile:

FROM tiangolo/node-frontend:10 as build-stage
WORKDIR /app

COPY package*.json /app/
RUN npm install

COPY ./ /app/
ARG configuration=production
RUN npm run build -- --output-path=./dist/out --configuration $configuration

# Stage 1, based on Nginx, to have only the compiled app, ready for production with Nginx
FROM nginx:1.15
COPY --from=build-stage /app/dist/out/ /usr/share/nginx/html

# Copy the default nginx.conf provided by tiangolo/node-frontend
COPY --from=build-stage /nginx.conf /etc/nginx/conf.d/default.confenter

Django Rest项目的Dockerfile:

# Pull base image
FROM python:3.7

# Set environment varibles
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# create root directory
RUN mkdir /web

# set working directory
WORKDIR /web

# Coppy current directory contents into the container
ADD . /web/

# Install any needed packages in requirements.txt
RUN pip install -r requirements.txt

以及docker-compose.yml文件:

version: '3'

services:
  db:
    image: mysql:5.7
    restart: always
    container_name: db
    environment:
      - MYSQL_HOST=localhost
      - MYSQL_PORT=3306  # cannot change this port to other number
      - MYSQL_ROOT_HOST=%
      - MYSQL_DATABASE=test
      - MYSQL_USER=belter
      - MYSQL_PASSWORD=belter_2017
      - MYSQL_ROOT_PASSWORD=123456_abc
    ports:
      - '3302:3306'

  web:
    build: ./orca/
    restart: always
    command: bash -c "python manage.py makemigrations && python manage.py migrate && python manage.py runserver 0.0.0.0:8000"
    container_name: web
    volumes:
      - ./orca:/code
    ports:
      - '8000:8000'
    depends_on:
      - db

  angular:
    build: ./ng-orca-new/
    container_name: angular
    ports:
      - '3000:80'

事先谢谢!

问题是由于nginx阻塞了请求。在该层再次添加头文件,生成以下nginx.conf:

server {
  listen 80;
  location / 
    add_header "Access-Control-Allow-Origin" "*";
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE';
    add_header 'Access-Control-Allow-Headers' 'X-Requested-With,Accept,Content-Type, Origin';

    root /usr/share/nginx/html;
    index index.html index.htm;
    try_files $uri $uri/ /index.html =404;
  }
}
