我有一个带有以下代码的应用程序:
quantity = 3
unit_types = ['MarineTrac','MotoTrac','MarineTrac']
airtime_plan = 'Monthly Airtime Plan'
url = "http://localhost:3000/home/create_units_from_paypal?quantity=#{quantity}&unit_types=#{unit_types}&airtime_plan=#{airtime_plan}"
begin
resp = Net::HTTP.get(URI.parse(URI.encode(url.strip)))
resp = JSON.parse(resp)
puts "resp is: #{resp}"
true
rescue => error
puts "Error: #{error}"
return nil
end
它通过 URL 参数查询字符串将数据发送到我的其他应用程序。这是其他应用程序的控制器方法的样子:
def create_units_from_paypal
quantity = params[:quantity]
unit_types = params[:unit_types]
airtime_plan = params[:airtime_plan]
quantity.times do |index|
Unit.create! unit_type_id: UnitType.find_by_name(unit_types[index]),
airtime_plan_id: AirtimePlan.find_by_name(airtime_plan),
activation_state: ACTIVATION_STATES[:activated]
end
respond_to do |format|
format.json { render :json => {:status => "success"}}
end
end
我收到此错误:
<h1>
NoMethodError
in HomeController#create_units_from_paypal
</h1>
<pre>undefined method `times' for "3":String</pre>
<p><code>Rails.root: /Users/johnmerlino/Documents/github/my_app</code></p>
我尝试使用 bothraw
和html_safe
on theparams[:quantity]
和 other params
,但仍然出现错误。注意我必须使用URI.encode(url)
,因为URI.parse(url)
返回了错误的 uri 可能是因为 unit_types 数组。
