javascript - Rails Controller 到 ajax

Question

我在这里有一个很好的查询。相信这就是我需要做的。

我有这行代码。

event = client.get_listings_by_event 1296393

现在，这段代码位于私有(private) def 方法中。我们称之为数据。

在我的显示方法中，我将其列为数据。

我想要得到这个响应(我目前可以在 byebug 中使用)，并在我已经运行并已经对其他 api 进行排序的 javascript 文件中使用它。

这是我得到的 byebug 回复

显然这只是第一项，我如何将其传递给 javascript ajax？

ajax 请求是否能够处理这种格式？

这是我当前的ajax请求

$.ajax({
    type: 'GET',
    crossDomain: true,
    dataType: 'json',
    url: 'https://',
    success: function(json) {

我可以将数据放入 url 区域 data.event 吗？

这是我的所有代码:

def gogodata
    # All methods require OAuth2 authentication. To get OAuth2 credentials for your
    # application, see http://developer.viagogo.net/#authentication.
    client = GogoKit::Client.new do |config|
      config.client_id = ENV['viagogo_key']
      config.client_secret = ENV['viagogo_secret']
    end



    # Get an access token. See http://developer.viagogo.net/#getting-access-tokens
    token = client.get_client_access_token
    client.access_token = token.access_token


    # Get a list of events, categories, venues and metro areas that match the given
    # search query

    event = client.get_listings_by_event @event.viagogolink
    byebug
    # Get the different event genres (see http://developer.viagogo.net/#entities)
    genres = client.get_genres



  end

编辑

我收到此错误，ActionController::UnknownFormat

关于这个 响应事件 如果有帮助，请使用代码

  respond_to :json, only: :data

   def data
     client = GogoKit::Client.new do |config|
       config.client_id = ENV['viagogo_key']
       config.client_secret = ENV['viagogo_secret']
     end
     token = client.get_client_access_token
     client.access_token = token.access_token
     event = client.get_listings_by_event(params[:id])
      respond_with event
   end

Answer 1

如果您想在前端(公开)使用数据，您需要首先将事件数据设为“公开”(您自己承认，您当前的实现是< em>private)，然后确保您的应用可以通过以下路由访问它:

#config/routes.rb
resources :clients do
   scope constraints: { format: "json" } do
      get :data, on: :member
   end
end

#app/controllers/clients_controller.rb
class ClientsController < ApplicationController
   respond_to :json, only: :data

   def data
      event = client.get_listings_by_event(params[:id])
      respond_with event
   end
end

这将允许您向上述路由发送请求，并根据需要操纵响应:

#app/assets/javascripts/application.js
$(document).ready(function(){
    $.ajax({
        type: 'GET',
        dataType: 'json',
        url: 'clients/1296393/data',
        success: function(data) {
            alert(JSON.stringify(data));
        });
});
