如何在响应命中URL时自动保存JSON响应数据？

我向第三方URL发送请求。他们收到我的请求后，会向我的网址发送回复。当响应到达我的URL时，我想自动将这些数据保存到我的表格中。如何在响应命中URL时自动保存JSON响应数据？

响应URL格式：

http://example.com/delivery_reports/new?data=%7B%22requestId%22%3A%22546b384ce51f469a2e8b4567%22%2C%22numbers%22%3A%7B%22911234567890%22%3A%7B%22date%22%3A%222014-11-18+17%3A45%3A59%22%2C%22status%22%3A1%2C%22desc%22%3A%22DELIVERED%22%7D%7D%7D

我的控制器：

def new   
    json = JSON.parse(params["data"])  
    requestId = json["requestId"] 
    numbers = json['numbers'] 

    numbers.each do |num| 
     @delivery_report = DeliveryReport.new 
     @delivery_report.request_id = requestId 
     @delivery_report.date = num[1]["date"] 
     @delivery_report.receiver = num[0].to_s 
     @delivery_report.status = num[1]["status"] 
     @delivery_report.description = num[1]["desc"] 
     @delivery_report.save 
    end  
    end

，当我在URL直接输入响应代码，但是当URL被击中时不会自动保存保存到我的表中的数据。

您的模型中有任何验证吗？尝试'保存！' - '@ delivery_report.save！'。看看它是否会抛出任何错误。 –

通过GET或POST发送响应吗？ – makhan

如果当你通过浏览器访问该链接，但不是因为API使用POST请求时，URL被击中它最有可能的工作。

添加路由到您的routes.rb：

post 'delivery_reports/new', to: 'delivery_reports#new'

我加入了路线。但是数据没有保存到db .. –

你在日志中看到API请求吗？你可以复制粘贴到你的问题？ – makhan

你可以在你的日志中找到一些符合'tail -n10000 | grep delivery_reports -A5 -B3' – makhan

看一看下面的代码片段。这应该是格式。格式化的Json应根据常规的参数名称进行格式化。你可以试试。

if params[:data].present?  
    request = params[:data][:request_id] 
    numbers = params[:data][:number] 
    #....

可能的方式来调试：

或者你可以尝试使用撬宝石，把binding.pry在动作块，然后你可以检查为右PARAMS。并检查您的记录保存过程。
您可以使用基于浏览器的gem来模拟相同数据的api命中，以在您的本地计算机上生成此问题，以实现期望的行为，您期望从完全相同的api命中。
你可以添加一个raise params.inspect来调试你的参数。但是这可能无法给你提供完整的信息，说明你的代码可能会破坏
