环境:mac for docker
前端: vue
后端: django
解决什么问题: 解决前后端跨域问题
1、首先通过docker run 运行临时nginx容器,将下面需要映射的文件及目录,全部通过docker cp 命令复制出来
然后将/opt/nginx/conf.d/default.conf文件, 文件内容修改如下:
server { listen 80; #listen [::]:80; server_name host.docker.internal, localhost, 127.0.0.1; #charset koi8-r; #access_log /var/log/nginx/host.access.log main; keepalive_timeout 70; gzip on; gzip_min_length 200; gzip_buffers 4 16k; gzip_comp_level 6; gzip_types text/plain application/javascript text/css application/xml text/javascript application/json; gzip_vary on; gzip_disable "MSIE [1-6]\."; gzip_proxied any; # 配置django ,如果符合 /api/ 开头的url,就转发到http://127.0.0.1:8000 location /api/ { proxy_pass http://host.docker.internal:8000; proxy_pass_request_headers on; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } # 配置vue,默认的所有的请求,都转发到 http://127.0.0.1:8080; 比上面多了几个配置,因为要支持websocket location / { proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_pass http://host.docker.internal:8080; proxy_pass_request_headers on; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } #location / { # root /usr/share/nginx/html; # index index.html index.htm; #} #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache‘s document root # concurs with nginx‘s one # #location ~ /\.ht { # deny all; #} }
2、启动docker-nginx, 将容器内80端口映射到宿主机的8001端口(8001未使用状态):
version: ‘3‘ services: nginx: container_name: nginx image: nginx:latest ports: - 8001:80 #network_mode: host volumes: - /opt/nginx/nginx.conf:/etc/nginx/nginx.conf - /opt/nginx/conf.d:/etc/nginx/conf.d - /opt/nginx/log:/var/log/nginx restart: always
3、本地启动vue(默认是8080端口)和django(默认是8000端口)
4、此时nginx 开始监听本地的8000端口和8080端口,所以打开前后端工程都要用8001了:
http://127.0.0.1:8001/
前端工程中,调用后端的接口变量,就需要配置成如下了:
let portUrl = "http://127.0.0.1:8001/api/";
需要注意的是:上面2个地址要一致,要么都是127.0.0.1要 么都是localhost,否则,还是会存在跨域问题
好的,现在应该没有跨域问题了,可以愉快的开发了。
