I have a rails controller that is making a web request, I would like to display the response body and status code inside of a view without saving the data to a model. I've tried using partials and instance variables but I've gotten no luck.

Here is what I have so far:

def create
    uri = URI.parse "https://#{login_params[:ip]}"
    http = Net::HTTP.new uri.host, uri.port

    http.use_ssl = true if uri.scheme == 'https' # Use SSL, Should probably be default
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE

    req = Net::HTTP::Post.new(uri.request_uri, headers)
    req.basic_auth login_params[:username].to_s, login_params[:password].to_s # Base64 encode username:password


    res = http.request(req, req_body) # make request

    body = Hash.from_xml(res.body)
    if res.code == 200
      redirect_to :show
    end 
end

Am I just better of making the request with Stimulus JS and appending the data to the screen?

CodePudding user response：

your issue here is you don't assign the value of your request to an instance variable for example you could do that:

def create
    uri = URI.parse "https://#{login_params[:ip]}"
    http = Net::HTTP.new uri.host, uri.port

    http.use_ssl = true if uri.scheme == 'https' # Use SSL, Should probably be default
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE

    req = Net::HTTP::Post.new(uri.request_uri, headers)
    req.basic_auth login_params[:username].to_s, login_params[:password].to_s # Base64 encode username:password


    res = http.request(req, req_body) # make request

    @body = Hash.from_xml(res.body)
    @code = res.code

    if res.code == 200
      redirect_to :show
    end 
end

then access it from the view like that:

<%= @body %>
<%= @code %>

CodePudding user response：

1. Save the response into an instance variable
2. render to the next action
3. Add this to the view:

<% if @resp %> 
  <%= @resp.body %> 
<% end %>
