使用logstah解析范围请求标头(Parsing range request header with logstah)

 我需要将范围请求值解析为logstash中的start_range和end_range。 数据来自json对象，如下所示： 
 
byte_range: "bytes=10-200"
 
 我想将start和end提取为单独的值，如下所示： 
 
start_range:10
end_range:200
 
 我还需要考虑到值可能如下所示： 
 
byte_range: "bytes=10-"
 
 并且仍然应该导致： 
 
start_range: 10
end_range: -
 
 我尝试使用grok过滤器这样做，但它不起作用： 
 
bytes=%{NUMBER:start_range}-%{NUMBER:end_range}
 
 有没有人知道如何尽可能简单地解决这个问题？ 

I need to parse a range request value into start_range and end_range in logstash. The data comes from a json object and looks like this:
 
byte_range: "bytes=10-200"
 
and I want to extract start and end into separate values like this:
 
start_range:10
end_range:200
 
I also need to take into account that the value could look like this:
 
byte_range: "bytes=10-"
 
and should still result in:
 
start_range: 10
end_range: -
 
I tried doing it like this with a grok filter but it does not work:
 
bytes=%{NUMBER:start_range}-%{NUMBER:end_range}
 
Does anyone have any idea how to solve this as simple as possible?
