使用rspadd标头在HAPROXY 1.6.9中添加CORS

Question

我已经在Apache上设置了HAPROXY，它工作正常，但是我无法从其他域调用api，这是CORS问题，所以我添加了

rspadd Access-Control-Allow-Origin：\ *

但仍然没有在api调用中添加响应头。 请告诉我。有没有其他方法可以实现它？

这是我的整个haproxy.cfg文件

global
    log 127.0.0.1   local2
    #log 127.0.0.1  local1 notice
    #log loghost    local0 info
    #log /dev/log local0 info
    log-tag haproxy
    maxconn 4096
    chroot /usr/share/haproxy
    uid 99
    gid 99
    daemon
    debug
    #quiet
