我正在使用Ruby on Rails 3,並試圖設置JSON/XML響應的值。如何在'format.json/xml {render:json/xml => @ user.to_json/xml}'中設置JSON/XML響應的標題?
在我的控制器我有
respond_to do |format|
format.xml { render :xml => @user.to_xml }
format.json { render :json => @user.to_json }
end
當我爲JSON/XML HTTP GET請求,它被設置共同的價值觀像這些
header:
date:
- Fri, 18 Feb 2011 18:02:55 GMT
server:
- Apache ...
etag:
- "\"0dbfd0ec23934921144bd57d383db443\""
cache-control:
- max-age=0, private, must-revalidate
x-ua-compatible:
- IE=Edge
x-runtime:
- "0.033209"
status:
- "200"
transfer-encoding:
- chunked
content-type:
- application/json; charset=utf-8 #or application/xml; charset=utf-8
http_version: "1.1"
message: OK
read: true
我想添加/套header
值並添加新參數,如message2
或header2
。
如何在format.json/xml { render :json/xml => @user.to_json/xml }
語法中做到這一點?
