Nginx 跨域配置
在 Nginx 的 server 或 location 块中添加以下配置,允许所有域名、方法和请求头的跨域请求:
conf
server {
listen 80;
server_name yourdomain.com;
location / {
# 允许所有域名跨域
add_header 'Access-Control-Allow-Origin' '*' always;
# 允许的 HTTP 方法
add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
# 允许的请求头
add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range' always;
# 允许暴露给客户端的响应头
add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range' always;
# 预检请求的缓存时间(单位:秒)
add_header 'Access-Control-Max-Age' 1728000 always;
# 处理 OPTIONS 预检请求
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain; charset=utf-8';
add_header 'Content-Length' 0;
return 204;
}
# 其他代理或转发配置
proxy_pass http://backend;
}
}
