nginx如何配置跨域请求?

nginx配置跨域，只需要在nginx的conf里面的location里面配置跨域参数即可，跨域参数是：

add_header 'Access-Control-Allow-Origin' *;
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Methods' *;
add_header 'Access-Control-Allow-Headers' 'Origin,X-Requested-With,Content-Type,Accept,token';

具体配置如下图：
