使用Nginx Lua拦截内容标头

我正在使用以下代码通过衡量协议将服务器端匹配发送到GA:

location = /example {    
    access_by_lua_block  {    
        local request = {
            v = 1,
            t = "pageview",
            tid = "UA-XXXXXXXX-Y",
            cid = ngx.md5(ngx.var.remote_addr .. ngx.var.http_user_agent),
            uip = ngx.var.remote_addr,
            dp = ngx.var.request_uri,
            dr = ngx.var.http_referer,
            ua = ngx.var.http_user_agent,
            ul = string.sub(ngx.var.http_accept_language, 1, 2)
        }
        local res = ngx.location.capture(  "/gamp",  {
            method = ngx.HTTP_POST,
            body = ngx.encode_args(request)
        })
    }
}
location = /gamp {
    internal;
    expires epoch;
    access_log off;
    proxy_pass_request_headers off;
    proxy_pass_request_body on;
    proxy_pass https://google-analytics.com/collect;
}

我希望能够从内容中传递更多信息,例如标题等。相应的标头(例如X-title)已经从后端(php / wordpress)生成,但是当我将dt = ngx.resp.get_headers()["X-title"]添加到请求中,该请求不检索任何内容。我认为这是因为nginx尚未看到它们。他们会以某种方式被拦截然后发送出去吗?
