项目中有时候会遇到跨域的问题，通常这个问题应该从server端解决，但是某些情况下我们不能修改server的代码，我们可以通过setup nginx来实现跨域。

还有一点需要注意，nginx不支持http 的option方法，所以需要做些特殊配置。下面是我项目中nginx.conf的详细配置（这个文件中没有配置nginx的负载均衡）同时nginx不支持else和其它的与或非等操作:

user  nginx;worker_processes  1;error_log  /var/log/nginx/error.log warn;pid        /var/run/nginx.pid;events {    worker_connections  1024;}http {    include       /etc/nginx/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  /var/log/nginx/access.log  main;    sendfile        on;    #tcp_nopush     on;    keepalive_timeout  265;    #gzip  on;    include /etc/nginx/conf.d/*.conf;    server {        keepalive_requests 240;        listen       80;   # nginx server deployed port (I am using docker, the docker port is 80)        server_name  127.0.0.1; # nginx deployed server ip        location  /{       if ($request_method = OPTIONS ) {            add_header 'Access-Control-Allow-Origin' '*';            add_header 'Access-Control-Allow-Credentials' 'true';            add_header 'Access-Control-Allow-Methods' 'POST,GET,DELETE,OPTIONS';            add_header 'Access-Control-Allow-Headers' 'x-method-override,content-type,accept';            proxy_pass  http://targetServerIP:port; # target server ip and port            return 200;         }         if ($request_method != OPTIONS ){             add_header 'Access-Control-Allow-Origin' '*';             add_header 'Access-Control-Allow-Credentials' 'true';             add_header 'Access-Control-Allow-Methods' 'POST,GET,DELETE,OPTIONS';             add_header 'Access-Control-Allow-Headers' 'x-method-override,content-type,accept';             proxy_pass  http://targetServerIP:port;  # target server ip and port         }        }    }}
