通过 http 标头传递真实性令牌 [英] Pass Authenticity token through http header

问题描述

我有一个使用令牌来验证用户身份的 rails 应用程序.目前我将令牌作为参数传递.我想改变这一点.我相信可以通过 html 标头传递它.我不明白如何使用 authenticate_or_request_with_http_token do |token, options|.我的 rails 应用程序实际上是我的 iphone 客户端的服务器.我不明白的是:

I have a rails application that uses a token to authenticate the user. Currently I am passing the token as params. I would like to change this. I believe it is possible to pass it through html header. I dont understand how to use authenticate_or_request_with_http_token do |token, options|. My rails app is actually a server for my iphone client. I things I dont understand are:

1. 我知道 options 是随机数，但是如何在我的客户端和服务器之间运行?

1. I know options is nonce but how will that work out between my client and server?

我如何在我的服务器代码中实际使用它.

How do I actually use this in my server code.

我可以使用 authenticate_or_request_with_http_token do |token, options| 来检查标头中的令牌，但如何在成功创建会话后将其插入标头.

I can use authenticate_or_request_with_http_token do |token, options| to check for token in the the header but how do I insert it into the header once a session is created successfully.

这是我的服务器会话控制器:

Here is my server Sessions Controller:

def create
if @user && @user.authenticate(params[:password])
 # @token = @user.auth_token
 @user.auth_token = SecureRandom.hex 
 @user.save
    respond_to do |format|
        format.json {render :json => {:status => "200", :message => "Logged in successfully", :auth_token => @user.auth_token}}
    end
else
    respond_to do |format|
        format.json {render :json => {:status => "401", :message => "wrong credentials"}}
    end
end
  end

  def destroy
    if(@user)
      @user.auth_token = ""
      @user.save
      respond_to do |format|
         format.json {render :json => {:status => "200", :message => "logged out successfully"}}
      end
    else
      respond_to do |format|
         format.json {render :json => {:status => "401", :message => "No User"}}
      end
   end
  end

def user
  @user = User.find_by_auth_token(params[:auth_token])
end

推荐答案

使用 response.headers 设置自定义标头.

to set custom headers you use response.headers.

类似的东西

response.headers["X-AUTH-TOKEN"] = auth_token

应该工作..阅读您使用的标题

should work.. to read the header you use

request.headers["X-AUTH-TOKEN"]

命名中的 X- 是一个很好的实践约定，所有自定义标头都应该在前面有一个 X-.

the X- in the naming is a good practice convention, all custom headers should have an X- in front.
