用nginx解决前端跨域问题
假如前端你项目部署在nginx的根目录下,然后项目需要请求后台小伙伴写的接口
nginx配置:
#user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 9511; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { root D:\xxx\xxx\xxx; #项目在计算机中的位置(前端你项目) index index.html index.htm; #指定项目入口文件 try_files $uri $uri/ /index.html; #解决vue-router的history模式 刷新404问题 } location /data/ { proxy_pass http://139.196.xxx.xx:8083;# 代理接口地址 } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # 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; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
然后在浏览器中输入localhost:9511就可以访问到项目了!!!并且可以请求到后盾接口数据!!!
又一次代理实践:
server { listen 8011; # listen qinghai:8011; # server_name somename alias another.alias; location / { root D:\project\fontEnd\xxx\menu; index index.html index.htm; } location /api { proxy_pass https://xxx.net;# 代理接口地址 } }
http://127.0.0.1:8011/ 即可访问
列几个nginx经常用到的命令
nginx -t 测试配置文件是否正确
start nginx 启动nginx
nginx -s reload 热更新
nginx -s quit 温柔停止
nginx -s stop 粗暴停止
