nginx小技巧

预请求

if ($request_method = OPTIONS ) {
    add_header Access-Control-Allow-Origin "*";
    add_header Access-Control-Allow-Methods "POST, GET, PUT, OPTIONS, DELETE";
    add_header Access-Control-Max-Age "3600";
    add_header Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept, Authorization";
    add_header Content-Length 0;
    add_header Content-Type text/plain;
    return 200;
}

备注： 需要放在location节点下面

yarn错误The engine "node" is incompatible with this module

yarn config set ignore-engines true
