vue.js使用代理和使用Nginx来解决跨域的问题

server { 
listen 8899;// 你的端口 
server_name localhost; 
root C:/ZOBSF_Fhttps://img.qb5200.com/download-x/dist;//你打包部署的文件路径 
#charset koi8-r; 
#access_log logs/host.access.log main; 
# 匹配 api 路由的反向代理到API服务 
location ^~/api { 
proxy_pass http://119.23.227.141:10001/;//你的后端IP和端口 
} 
#根据路由设置，避免出现404 
location / { 
try_files $uri $uri/ @router; 
index index.html; 
} 
location @router { 
rewrite ^.*$ /index.html last; 
} 
#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; 
#} 
}
