Error: Data must be an object, value must be an array - Posting Expo push token from Rails app

Question

我有一个 Rails 应用程序，我想通过 sidekiq 向 Expo 发送一个 post 请求，以便处理应用程序内通知。该应用程序的 API 是使用 Node.JS 构建的，推送令牌使用此代码成功执行：

                    axios({
                        method: "post",
                        url: "https://exp.host/--/api/v2/push/send",
                        data: {
                            to: result.expo_push_token,
                            title: `${data.user.first_name}`,
                            sound: "default",
                            body: shortMessage,
                            data: {
                                status: "ok",
                                body: shortMessage,
                                title: `${data.user.first_name}`,
                                msgUser: data.user,
                                convoId: data.room,
                            }
                        }
                    })

在 Rails 应用程序中，一切正常，直到我想将数据对象传递给该应用程序。这是有效的方法：

        push_tokens = PushToken.where(user_id: other_user)

        push_tokens.each do |token|
            params = ({

              to: token.expo_push_token,
              title: user.first_name,
              sound: "default",
              body: msg.body
            })


            puts params
            puts params.class

            x = Net::HTTP.post_form(URI.parse('https://exp.host/--/api/v2/push/send'), params)
            puts x.body

然后当我添加数据对象时，出现错误：{'errors':[{"code":'API_ERROR','message':'child \'data\' fails because [\'data\' must be an object], \'value\' must be an array.'}]}

        push_tokens.each do |token|
            params = ({

              to: token.expo_push_token,
              title: user.first_name,
              sound: "default",
              body: msg.body,
              data: {
                status: "ok",
                msgUser: {
                  id: user.id,
                  avatar_file_name: user.avatar_file_name,
                  first_name: user.first_name,
                },
                convoId: msg.convo_id,
                body: msg.body,
                title: user.first_name,
              },
            })


            puts params
            puts params.class

            x = Net::HTTP.post_form(URI.parse('https://exp.host/--/api/v2/push/send'), params)
            puts x.body

最初，我将 ActiveRecord 传递给数据 msgUser: user，并认为这可能是问题所在，但当我自己创建一个数组时，它没有任何区别：msgUser: {id: user.id, avatar_file_name: user.avatar_file_name, first_name: user.first_name,},。一个简单的 data: {status: 'ok'} 也不起作用。

我也用 [ ]、params.to_json 和 params.as_json 尝试过 data: [status: 'ok']，但我得到了同样的错误。

如何通过此 Rails post 请求将此 data 对象成功发送到 expo 推送令牌？

这是我应用程序中的有效代码，你能试试这个吗

在您触发作业的控制器中，执行以下操作

# Controller
push_tokens.each do |token|
  WorkerClass.perform_async(token, @user)
end

# Worker file
class WorkerClass
  def perform(token, user)
    uri = URI.parse("https://exp.host/--/api/v2/push/send")
    Net::HTTP.start(uri.host, uri.port, use_ssl: true) do |http|
      http.verify_mode = OpenSSL::SSL::VERIFY_NONE
      request = Net::HTTP::Post.new(uri.path, {'Content-Type' => 'application/json'})
      request.body = {"to"=>token.expo_push_token, "title"=>user.first_name, "body"=>"your_message", "data"=>{"status"=>"ok"}}.to_json
      response = http.request(request)
    end
  end
end
