Lua string concatenation in Json blob -


i have question string concatenation.

i have example trying append value inside json block variable value

example: 

clock = os.clock() body = "{\"name\":\"stringvalue\" .. clock }" print(body)

when run following output: 

{"name":"stringvalue" .. clock }

what expecting 

{"name":"stringvalue0.010117"}

how make variables value added string?

this instance using [[ ]] delimited strings useful:

clock = os.clock() body = [[{"name":"stringvalue]] .. clock .. [["}]] print(body)

to continue using double quoted string, variable assignment following (note how quote after stringvalue not escaped):

body = "{\"name\":\"stringvalue" .. clock .. "\"}"
