错误:数据必须是对象,值必须是数组-从Rails应用程序发布Expo推送令牌

我有一个Rails应用程序,并且我想通过sidekiq发送一个发布请求到Expo,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,并且推送令牌已使用以下代码成功执行:

                    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,它给出了错误:{'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,我正在将ActiveRecord传递给数据到msgUser: user,并认为可能是问题所在,但是当我自己创建数组时msgUser: {id: user.id, avatar_file_name: user.avatar_file_name, first_name: user.first_name,},并没有什么不同。简单的data: {status: 'ok'}也不起作用。

我也尝试将data: [status: 'ok'][ ]params.to_jsonparams.as_json一起使用,但遇到同样的错误。

如何通过此Rails发布请求将这个data对象成功发送到博览会推送令牌?

这是我应用程序中的有效代码,您可以尝试一下

在您要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
