jsonvalidator

A json validator based on json template which supports go-playground/validator and regular expression.

Installation

go get github.com/seaguest/jsonvalidator

Usage

The template json value is composed by type|rule. for example:

all supported type:

tokenInt       = "{int}"
tokenFloat     = "{float}"
tokenString    = "{string}"
tokenList      = "{list}"
tokenRe        = "{re}" // regular expression
tokenSeparator = "|"

{string}|eq=ok    declare the node as string and equal ok
{int}|eq=0        declare the node as int and equal 0
{re}|^0$          declare validation type as regular expression
