我想用 ROR 中的设计进行 JSON 身份验证。我设法配置设计以响应 Json。但我不知道下一步如何进行。

  1. 据我了解，登录时，我需要从服务器获取会话 cookie。
  2. 登录后，我需要在后续请求中设置cookie。

我用 curl 做了实验。登录时似乎可以正常工作，但我不知道如何进行第 2 步。

步骤1：

curl -i -c cookie.txt --data "user[email]=aaa@hotmail.com&user[password]=bbb" 
http://localhost:3000/users/sign_in.json

来自服务器的响应头

第2步

curl -b cookie.txt http://192.168.1.104:3000/user/show
