> # 背景
> 历史遗留客户端, 只接受特定大小写的 HTTP 响应 HEAD 字段
>
> - 比如 FooBar: 1234567
> - 但是, 后来使用标准化库后,自动将字段名修订为 Foobar 类似字串
> - 客户端就无法接受了
> - 同时,此时的 Nginx 是作为代理,将后端动态系统发布出来的,类似:
> + proxy_pass http://myapi/;
>
> # 尝试
> 发现有两个库可操作 HTTP response HEAD:
>
> - https://github.com/openresty/lua-resty-core
> - https://github.com/openresty/headers-more-nginx-module
>
> 前者是内置的,后者得编译安装
>
> 进行类似尝试时:
>
> ngx.header["X-My-Header"] = 'blah blah'
> local h = ngx.resp.get_headers()
> for k, v in pairs(h) do
> ngx.say(k,'\t', v)
> if k ~='x-my-header' then
> ngx.header["My-Header-X"] = 'blah blah'
> end
> end
>
>
> 报错:
> 2015/08/18 22:06:08 [error] 47371#0: *12 attempt to set
> ngx.header.HEADER after sending out response headers, client:
> 127.0.0.1, server: , request: "GET /echo HTTP/1.1", host:
> "127.0.0.1:8081"
>
>
> 如果将测试脚本部署在代理路径上,类似:
>
> location / {
> proxy_pass http://myapi/;
> content_by_lua_file conf/lua/echo.lua;
> }
>
> 则根本不执行
>
>
> # 提问:
>
> - 如何在 proxy_pass 配置路径上,对代理的响应数据进行提取和修订?
> - 以上两个库,哪个最合理实时对请求响应的 HEAD 字段名进行更改?
