大叔经验分享（77）openresty（nginx+lua）发http请求

openresty（nginx+lua）发http请求

利用location+proxy_pass间接实现

    location ^~ /test/http {
        internal;
        proxy_pass http://test.com/path;
    }

lua代码

local res, err = ngx.location.capture("/test/http", {
    method = ngx.HTTP_POST,
    body = body
});
if res then
  ngx.log(ngx.INFO, "response:"..res.body)
else
  ngx.log(ngx.INFO, "error:"..err)
end
