Rails使用JSON处理POST请求-RailsprocessPOSTrequestwithJSON

The event data received from params[:json]:

来自params的事件数据[:json]:

{
"event": {
    "event_type": "signature_request_sent",
    "event_time": "1394642012",
    "event_hash": "xxxxx"
},
"account_guid": null,
"client_id": "xxxx",
"signature_request": {
    "signature_request_id": "xxxxxxx",
    "title": "Review Agreement",
    "original_title": "Review Agreement",
    "message": null,
    "test_mode": true,
    "is_complete": false,
    "final_copy_uri": "/v3/signature_request/final_copy/xxxxx",
    "files_url": "https://api.hellosign.com/apiapp.php/v3/signature_request/files/xxxxx",
    "details_url": "https://www.hellosign.com/home/manage?locate=xxxxx",
    "requester_email_address": "xxxxxxx",
    "signatures": [
        {
            "signature_id": "xxxxx",
            "has_pin": false,
            "signer_email_address": "xxxx@gmail.com",
            "signer_name": "admin",
            "order": null,
            "status_code": "awaiting_signature",
            "signed_at": null,
            "last_viewed_at": null,
            "last_reminded_at": null
        }
    ]
}
}

How can I parse "j" to save the "event_type" and the "signature_request_id" for example?

如何解析“j”来保存“event_type”和“signature_request_id”?

Thanks

谢谢

Also: this is the actual callback from the console:

另外:这是控制台的实际回调:

2 个解决方案

j = JSON.parse(params[:json])
j['event']['event_type'] # => "signature_request_sent"
j['signature_request']['signature_request_id'] # => "xxxxxxx"

require 'json'

#in your code 
json_data = JSON.parse(params[:json])
