如何在Ruby中使用机械化或法拉第发送JSON表单数据

Question

我想从使用JSON数据来设置自定义搜索参数的网站中检索数据，这些参数似乎通过AJAX请求。传输的数据在Firebug中的XHR->请求有效载荷下显示：

{"filters": [{"action": "post", "filterName": "Hersteller", "ids": [269], 
"settingName": "Hersteller", "settingValue": "ValueA"}, 
{"action": "delete", "filterName": "Modelle", 
"settingName": "Modelle", "settingValue": ""}]}

.

该站点不会传输任何帖子参数，但只有此JSON编码的数据以应用搜索条件。将此数据传递为具有机械化的后参数不起作用。

如何在Ruby上使用Chanchize或Faraday在Rails上传输此数据？

Answer 1

用机械化，你会做：

agent.post url, data.to_json, {'Content-Type' => 'application/json'}

.

Answer 2

我想出了一种方法：

connection = Faraday.new

fetched_page = connection.post do |request|
  request.url 'http://www.site.com'
  request.headers['Content-Type'] = 'application/json'
  request.body = '{"filters": [{"action": "post", "filterName": "Hersteller", "ids": [269], 
"settingName": "Hersteller", "settingValue": "ValueA"}, {"action": "delete", "filterName": "Modelle", "settingName": "Modelle", "settingValue": ""}]}'
end
