我有一個簡單的開箱滑軌服務器運行,我想弄清楚如何使它與If-Modified-Since標題一起工作。我正在使用以下curl請求。Rails 3 HTTP-header If-Modified-Since使用curl
捲曲-I本地主機:3000 /表演/ 1 --header '如果-Modified-Since的:週四2012年6月21日19點16分二十秒GMT'
我總是得到200 OK,但我想304不改性。
當我通過瀏覽器做到這一點時,我得到了304未修改,但沒有捲曲。
我做錯了嗎?
UPDATE
如果我運行
捲曲-v -I本地主機:3000 /顯示/ 1 --header '的If-Modified-時間:星期三,2012年6月21日19時16分二十秒GMT'
我得到:

的控制器Rails代碼是:
def index
@shows = Show.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @shows }
end
end
的鉻輸出如下:

使用'-v'運行'curl'並粘貼輸出,粘貼瀏覽器的輸出(如果您使用的是瀏覽器,只需打開Web工具並檢查請求 - 響應)。 –
請發佈您的ShowsController代碼,特別是show動作。 –
