nignx 配置允许跨域访问

add_header Access-Control-Allow-Methods *;
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Credentials true;
add_header Access-Control-Allow-Headers Token,groupid,app,appid,projectid,project_id,Project-Id,appcode,Content-Type,Upgrade,Connection,X-Real-IP,Company-Id,companyID,pf_token,pf_c_token,company_id,token,Authorization,Accept,Referer,*;

if ($request_method = OPTIONS){
               return 200;
}

举例

server {
    listen 8091;
   

    location / {

	   add_header Access-Control-Allow-Methods *;
           add_header Access-Control-Allow-Origin *;
           add_header Access-Control-Allow-Credentials true;
           add_header Access-Control-Allow-Headers Token,groupid,app,appid,projectid,project_id,Project-Id,appcode,Content-Type,Upgrade,Connection,X-Real-IP,Company-Id,companyID,pf_token,pf_c_token,company_id,token,Authorization,Accept,Referer,*;

	   if ($request_method = OPTIONS){
               return 200;
           }
        proxy_pass http://127.0.0.1:8092;
    }     
}

解释：

#允许跨域请求的域，*代表所有
add_header 'Access-Control-Allow-Origin' *;
#允许带上cookie请求
add_header 'Access-Control-Allow-Credentials' 'true';
#允许请求的方法，比如 GET/POST/PUT/DELETE
add_header 'Access-Control-Allow-Methods' *;
#允许请求的header
add_header 'Access-Control-Allow-Headers' *;
