Ruby on Rails从fcm响应中获取body对象

Question

我在rails ruby​​ on rails上实现了fcm for push notification。但是我收到了send（）的响应，格式如下。我只需要body属性的值。我对rails上的ruby很新。请指导我如何实现它。

fcm = FCM.new(server_key)   
options = {
        priority: "high",
        # collapse_key: "updated_score",
        notification: {
            title: "Hi Android",
            body: "Hi, Worked perfectly"
        }
    }
response = fcm.send([device_token], options)

这是我的回答

Answer 1

假设您的回答是hash

body =  hash[:data][:body].gsub(/[\"]/,"")

并且输出将是这样的： -

"{multicast_id:8218758506962978728,success:1,failure:0,canonical_ids:0,results:[{message_id:0:1514875371230492%ebb60861ebb60861}]}"

Answer 2

你可以关注ruby OpenStruct库，就像这样

object = JSON.parse(response, object_class: OpenStruct)

然后你可以找到基于对象的价值，非常好地解释here
