Validating user input in perl
Not all of these are as effective as one would hope: A better approach to validating JSON input is the use of a JSON schema.Similar to the XML schema, which is written in pure XML format for validating XML, JSON schema is written in pure JSON format for validating JSON. There are almost 30 validator implementations written for Java, Ruby, C, C , Python, Java Script Perl and other languages.I work on web service APIs to create new and interesting small business marketing solutions.
This really simplifies the entire process of trying out a schema.To interactively execute any of the tutorial examples below, I recommend using this validator, which implements the fge/json-schema-validator code from Git Hub.You’ll find that using this validator makes playing with a schema and trying out various validation scenarios quite simple.If you get into syntactic trouble with either and want to know what the problem is, use the JSON lint web page to validate the JSON formatting.
We’ve only scratched the surface of what is possible using JSON schema to validate JSON requests.By adding a pattern constraint for type string we can use a regular expression to validate the string matches exactly: Developers have the freedom to create arbitrarily complex custom data types by using composition of the native types.
