如何在 Rails 上使用 Ruby 从 Facebook 营销 API 获得潜在影响 5

Question

我正在尝试获取基于 Python 的 potential reach from the Facebook Marketing API using Ruby on Rails 5. I found the Ruby SDK here but I can't see the sample codes nor the functions that I need for getting the data that I want. I also found this post，并尝试将语言转换为 Ruby，这让我得到了这段代码：

require "facebook_ads"

class FacebookApi
  attr_reader :ad_instance

  def initialize(opts={})
    @ad_instance = FacebookAds::AdAccount.get("act_#{opts[:account_id]}")
    raise 'Account ID Key must be provided' unless opts[:account_id]
  end

  def get_target()
    targeting_spec = {
      'geo_locations': {
        'countries': ['US'],
      },
      'age_min': 20,
      'age_max': 40,
    }

    params = {
      'targeting_spec': targeting_spec,
    }

    @ad_instance.get_reach_estimate(params: params)
  end
end

但是，找不到函数get_reach_estimate。

我也尝试模拟示例 cURL 命令并提出以下测试脚本：

require 'net/http'
require 'uri'
require "erb"
include ERB::Util

class FacebookApi
  def get_target()
    account_id = <ACCOUNT_ID>
    access_token = <USER_ACCESS_TOKEN_WITH_ADS_MANAGEMENT_PRIVILEGE>
    uri = URI.parse("https://graph.facebook.com/v2.10/act_#{account_id}/reachestimate")
    request = Net::HTTP::Post.new(uri)
    request.set_form_data(
      "access_token" => access_token,
      "targeting_spec" => url_encode("{\"geo_locations\": {\"countries\":[\"US\"]}, \"age_min\": 20, \"age_max\": 40}")
    )

    req_options = {
      use_ssl: uri.scheme == "https",
    }

    response = Net::HTTP.start(uri.hostname, uri.port, req_options) do |http|
      http.request(request)
    end

    puts response.code
    puts response.body
  end
end

请注意，我在我的代码中使用了实际的帐户 ID 和访问令牌。就藏在这里吧。所以上面的代码现在 returns 出现以下错误：

    {
      "error": {
        "message": "Unsupported post request. Object with ID <ACCOUNT_ID> does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api",
        "type": "GraphMethodException",
        "code": 100,
        "fbtrace_id": "ESJks9/KxJC"
      }
    }

我确定我添加了对我的访问令牌的 ad_management 访问权限。我还尝试删除 URI 中的前缀 act_ 但结果相同。我现在遇到了死胡同，所以我想就如何做到这一点提出一些建议。非常感谢。

原来是因为post的要求。我应该改用 GET 请求。这是我的工作代码，带有针对目标规范的附加 interest 参数。

def get_target(interest_id, interest_name)
    account_id = @account_id
    access_token = @access_token
    url = "https://graph.facebook.com/v2.10/act_#{account_id}/reachestimate"

    params = {
      "access_token" => access_token,
      "targeting_spec" => "{" +
          "\"geo_locations\": {\"country_groups\":[\"Worldwide\"]}," +
          " \"age_min\": 20, \"age_max\": 40," +
          " \"interests\": [" +
            "{\"id\":#{interest_id}, \"name\":\"#{interest_name}\"}" +
          "]" +
        "}"
    }

    response = get_response(url, params)

    response
end

def get_response(url, params)
    uri = URI.parse(url)
    uri.query = URI.encode_www_form(params)

    http = Net::HTTP.new(uri.host, uri.port)
    http.use_ssl = true
    request = Net::HTTP::Get.new(uri)
    response = http.request(request)

    response.body
end
