ruby-on-rails - Rails 将 auth_token 渲染到 API 响应 header

Question

我有自定义 JSON 身份验证 API(没有设计等)。如何将 @user.authentication_token 渲染到响应 header 而不是正文？

在 sessions_controller.rb

  def create

    if @user && @user.authenticate(params[:user][:password])
      @user.sign_in_count += 1
      @user.save!

      render  status: 200,
              json: { success: true,
                      info: "Logged in sucessfully.",
                      data: { auth_token: @user.authentication_token } }
    else
      render  status: :unprocessable_entity,
              json: { success: false,
                      info: "Login failed." }
    end
  end

试试 response.header["auth_token"]

    def create

        if @user && @user.authenticate(params[:user][:password])
          @user.sign_in_count += 1
          @user.save!

          render  status: 200,
                  json: { success: true,
                          info: "Logged in sucessfully."}
                   response.headers["auth_token"] = @user.authentication_token

        else
          render  status: :unprocessable_entity,
                  json: { success: false,
                  info: "Login failed." }
    end
  end
