Question

我有一个简单的sinatra应用程序，它应该接收使用查询参数的GET请求，并获取这些参数并将它们转储到txt文件中。

当我使用telnet在本地测试时 - 一切都很棒。我收到了200条回复。第二个我把它全部放在heroku上，没有骰子。一切都有400 BAD_REQUESTS。当我使用浏览器时，一切都很好。我只是不能使用telnet（或我的arduino，这是我将使用的）发送。

直播网站： http://weathervane.herokuapp.com/

示例查询字符串： /sensor?temp=100&hum=200

此外，除了HTTP错误之外，看起来第二个参数（hum）也会被切断： http://cl.ly/image/3P46382p0D0v

这是索引路径

get '/' do
  erb :index
end

这是/传感器路线。

get '/sensor' do

  File.open 'temp_data.txt', 'w' do |f|
    f.write params[:temp]
  end

  File.open 'hum_data.txt', 'w' do |f|
    f.write params[:hum]
  end

  "OK, Temp: #{params[:temp]} & Hum: #{params[:hum]}" 

end

同样，这一切都在本地工作......我只是错过了我的heroku设置中的一步吗？

更新：以下是我尝试获取索引和传感器路径时的telnet打印输出。这只是因为我没有在请求中添加host：头。

标头中没有主机的索引。

标题中包含主机的索引。（看起来它就行了！）

这是没有主机头的/ sensor路由。

这是带有主机头的/ sensor路由。看看可爱的200 ok状态。 :)

OK, Temp: 100 & Hum: 200

heroku上的Sinatra应用程序使用GET和查询参数提供400个BAD_REQUEST错误
