c# serialized JSON date to ruby

问题

I have a C# application that serializes its DTOs to JSON and sends them accros the wire to be processed by Ruby. Now the format of the serialized date is like so:

/Date(1250170550493+0100)/

When this hits the Ruby app I need to cast this string representation back to a date/datetime/time (whatever it is in Ruby). Any ideas how I would go about this?

Cheers, Chris.

回答1:

You could parse out the milliseconds since the epoch, something like:

def parse_date(datestring)
  seconds_since_epoch = datestring.scan(/[0-9]+/)[0].to_i / 1000.0
  return Time.at(seconds_since_epoch)
end

parse_date('/Date(1250170550493+0100)/')

You'd still need to handle the timezone info (the +0100 part), so this is a starting point.

回答2:

You could use Json.NET to serialize your DTOs instead of the built in .NET JSON serializer. It gives you flexibility over how to serializing dates (i.e. as a constructor, ISO format, etc).

回答3:

.NET serializes in milliseconds from the epoch, so you need to divide the part before the timezone by 1000. Other wise your dates will be thousands of year off

回答4:

You can use Time.strptime to parse this to a Time object with the correct time zone:

Time.strptime(string, "/Date(%Q%z)/")

For example:

string = "/Date(1250170550493+0100)/"
Time.strptime(string, "/Date(%Q%z)/")
#=> 2009-08-13 14:35:50 +0100
