I have encountered this and other issues as well.

@liuhongda11 For the first example, jsonpath.Get("$.welcome.123456[1]", v), I would propose you use bracket-notation in your path, such as: 

jsonpath.Get(`$.welcome["123456"][1]`, v)

I haven't attempted with a hyphen in the index, but I'm guessing that can be solved using bracket-notation as well. Note that I use double-quotes (") in the path above. When using single quotes (') it seems like the number is treated as a character and thus won't work for numbers with more than one digit.
