如何使用 Rails 从 API 获取 POST 请求

Question

I got POST request from API. I checked content-type, it's x-www-form-urlencoded, but body request also contains JSON. How can I parse from JSON in hash?

Parameters of request in console: Screenshot || Parameters: {"vpbx_api_key"=>"etxojfklr6nue6tl627pn5sdi0koov7t", "sign"=>"ad0c49034c8d83a7d7f1b433afc2ed5a9aa08d933dba3724062aed0c3d1a79bb", "json"=>"{\\"entry_id\\":\\"MjYyNjQ2NzM1Njo0Mg==\\",\\"call_id\\":\\"MToxMDAxNDAzOTo0Mjo4Mjc2NzEzMzk=\\",\\"timestamp\\":1485939839,\\"seq\\":2,\\"call_state\\":\\"Disconnected\\",\\"location\\":\\"abonent\\",\\"from\\":{\\"number\\":\\"79268220697\\",\\"taken_from_call_id\\":\\"MToxMDAxNDAzOTo0Mjo4Mjc2NzEwOTA6MQ==\\"},\\"to\\":{\\"extension\\":\\"2\\",\\"number\\":\\"79154612023\\",\\"line_number\\":\\"74953749768\\"},\\"disconnect_reason\\":1100}"}

If you want to keep the form encoded that way, you will have the parameters in the params collection. That means you could be parsing that JSON doing something as:

def my_method_to_process_the_post
    parsed = JSON.parse params[:json]
end

'json' is the key for the json that you are receiving in the payload.
